[0030] The following describes the various embodiments of the present invention.

[0031] (Embodiment 1) Figure 1 shows the wristwatch 1 according to Embodiment 1 worn on the user's left arm. Figure 1(a) shows the wristwatch 1 together with the user's upper body, and Figure 1(b) is an enlarged view of the wristwatch 1 from a different angle than Figure 1(a). In Figure 1(b), arrow A indicates the direction of the user's line of sight when viewing the wristwatch 1 worn on the left wrist. That is, when a user views the wristwatch 1 worn on the left wrist, it is common for the user to look at the wristwatch 1 with their elbow slightly bent toward their body (towards their stomach or chest), and this is the direction of the line of sight. In Figure 1(b), arrow A is depicted as being in a horizontal plane, but in reality, the direction of the line of sight is generally directed diagonally downward from the user's eyes.

[0032] Figure 2 is a diagram illustrating the watch body 100 of the watch 1 according to Embodiment 1 and the display section 200 formed on five surfaces of the watch body 100, excluding the bottom surface which faces the wearer's wrist during use. Figure 2(a) is a perspective view of the watch body 100, and Figure 2(b) is a plan view showing the display section 200 of the watch 1 unfolded into five display sections 210 to 214. Figure 2(c) is a bottom view showing the display section 200 of the watch 1 unfolded into five display sections 210 to 214.

[0033] The configuration of the wristwatch 1 according to Embodiment 1 will be described with reference to Figures 1 and 2. The wristwatch 1 according to Embodiment 1 comprises a rectangular parallelepiped wristwatch body 100, five display units 210 to 214 formed over the entire area of ​​five of the six surfaces constituting the surface of the wristwatch body 100, excluding the bottom surface which faces the user's arm when in use (the top surface and four side surfaces), a belt 300 for attaching the wristwatch 1 to the user's arm, a display control unit (the display control unit will be described later with reference to Figure 3) that controls the display of each of the five display units 210 to 214, and a detection unit that detects the position information of the wristwatch 1. The belt 300 is not an essential component of the wristwatch 1, but is a preferred component. In this embodiment, the detection unit comprises two image sensors 50, 60 installed at any part of the wristwatch 1, and a calculation unit that extracts information regarding the positional relationship between the user's eye and the wristwatch 1 from the image of the user's eye captured by the two image sensors 50, 60. The detection unit can detect information regarding the positional relationship between the user's eye and the watch 1 as positional information for the watch 1. The display control unit has the function of controlling the display of each of the five display units 210 to 214 based on the information detected by the detection units 50 and 60. In this application, at least one "information" may be read as "data".

[0034] As shown in Figure 1, the image sensors 50 and 60 are preferably located at the two corners on the upper surface of the rectangular watch body 100 that are closest to the user in normal use. However, the image sensors 50 and 60 may also be located at other corners on the upper surface of the watch body 100. Furthermore, one, three, or four or more image sensors may be placed on the watch body 100 or the strap 300. When four image sensors are placed on the watch 1, preferably, one image sensor can be placed near the vertex where adjacent sides of the watch 1 meet the upper surface of the watch 1. Examples of image sensors include CCD (Charge Coupled Devices) image sensors and CMOS (Complementary Metal Oxide Semiconductor) image sensors. The lens of the image sensor is preferably capable of wide-angle imaging centered on the image sensor. In this invention, "formed throughout the entire area" means that it is sufficient if it appears to be formed throughout the entire area from the user's perspective, and it does not have to be formed throughout the entire area in a strict sense. Therefore, even if there is a gap between the display sections 210 and 214 that cannot be displayed, it is included in the category of "formed throughout the entire area".

[0035] As shown in Figure 2(a), the watch body 100 is a rectangular parallelepiped having a predetermined thickness t, and as shown in Figure 1, five display sections 210 to 214 are formed on the top surface 110 opposite to the bottom surface and on the four sides (first side 111, second side 112, third side 113, and fourth side 114). Of the five display sections 210 to 214, the display section formed on the top surface 110 of the watch body 100 is called the top display section 210, the display section formed on the first side 111 of the watch body 100 is called the first side display section 211, the display section formed on the second side 112 of the watch body 100 is called the second side display section 212, the display section formed on the third side 113 of the watch body 100 is called the third side display section 213, and the display section formed on the fourth side 114 of the watch body 100 is called the fourth side display section 214.

[0036] The five display sections 210 to 214 consist of five organic EL (Electro-Luminescence) display sheets. Specifically, the top display section 210 consists of a top-type organic EL display sheet, the first side display section 211 consists of a first-side-type organic EL display sheet, the second side display section 212 consists of a second-side-type organic EL display sheet, the third side display section 213 consists of a third-side-type organic EL display sheet, and the fourth side display section 214 consists of a fourth-side-type organic EL display sheet. When describing the first side display section 211, the second side display section 212, the third side display section 213, and the fourth side display section 214 together or individually, they may be referred to as "side display sections 210 to 214".

[0037] In the following description, when the five display units 210 to 214 are described as corresponding organic EL display sheets, the same reference numerals as the five display units 210 to 214 will be used for each organic EL display sheet, such as the top organic EL display sheet 210, the first side organic EL display sheet 211, the second side organic EL display sheet 212, the third side organic EL display sheet 213, and the fourth side organic EL display sheet 214.

[0038] Furthermore, when describing the top-side organic EL display sheet 210, the first-side organic EL display sheet 211, the second-side organic EL display sheet 212, the third-side organic EL display sheet 213, and the fourth-side organic EL display sheet 214 together, they may be referred to as "each organic EL display sheet 210-214." Also, when describing the first-side organic EL display sheet 211, the second-side organic EL display sheet 212, the third-side organic EL display sheet 213, and the fourth-side organic EL display sheet 214 together, they may be referred to as "each side organic EL display sheet 211-214."

[0039] Each of these organic EL display sheets 210-214 is attached one by one to the top surface 110 and four sides (first side 111, second side 112, third side 113, and fourth side 114) of the watch body 100, that is, to a total of five surfaces. This constitutes the watch 1 shown in Figure 1. In Figure 1, the state in which the analog time is displayed is shown, but when nothing is displayed, the five surfaces of the watch body 100, excluding the bottom surface, will be completely blank. Here, "blank" means that not only the analog time display, but also the digital time display and various other displays are not being shown.

[0040] In this case, the display unit 200 is constructed by attaching five organic EL display sheets (each organic EL display sheet 210-214) one by one to the watch body 100. By doing so, the corners of the watch 1 (the corners formed by the top organic EL display sheet 210 and the side organic EL display sheets 211-214) can be made right angles, and the flatness of each organic EL display sheet 210-214 can be increased, resulting in a simple and pleasing appearance.

[0041] Furthermore, a first electrode group 120 for supplying power and electrical signals to each organic EL display sheet 210-214 is exposed on five sides of the watch body 100, namely the top surface 110 and four sides (first side 111, second side 112, third side 113, and fourth side 114). On the other hand, a second electrode group 220 for receiving power and electrical signals from the first electrode group 120 is provided on the back surface of each organic EL display sheet 210-214 at a position corresponding to the first electrode group 120. The first electrode group 120 of the watch body 100 and the second electrode group 220 of each organic EL display sheet 210-214 are electrically connected to each other by their corresponding electrodes. In addition, a drive circuit for supplying electrical signals to control the lighting state of each pixel of each organic EL display sheet 210-214 is provided on the back surface of each organic EL display sheet 210-214. Note that the drive circuit is not shown in Figure 2.

[0042] Figure 3 is a functional block diagram showing the configuration of the control system for operating the wristwatch 1 according to Embodiment 1. The functional block diagram shown in Figure 3 mainly shows the functional blocks necessary for displaying information, among the various functions of the wristwatch 1 according to Embodiment 1.

[0043] On the wristwatch body 100, there is a display image selection unit 410 which serves as a user interface that allows the user to select what to display on the five display units 210 to 214 (each organic EL display sheet 210 to 214), an image data storage unit 420 which stores the images to be displayed on each organic EL display sheet 210 to 214, a synchronization signal generation unit 430 which generates a synchronization signal to synchronize the organic EL display sheets 210 to 214 so that the images displayed on each organic EL display sheet 210 to 214 are linked or related images, a time data generation unit 440 which generates the current time data, a display control unit 450 which controls the display of each organic EL display sheet 210 to 214, and a calculation unit 460 which identifies the position of a person's eyes from images captured by image sensors 50 and 60 and performs calculations to determine the direction toward the display unit 210 from the position of the eyes. The calculation unit 460 is also an example of a detection unit. The images displayed on each of the OLED display sheets 210 to 214 may be images stored in the image data storage unit 420, images generated by an image data generation unit (not shown), or images received from an external source via communication. For example, images from the user's smartphone or images from a contracted video distribution company may be displayed on the OLED display sheets 210 to 214.

[0044] On the other hand, the display unit 200 is equipped with a drive circuit 510 for the top organic EL display sheet 210, a drive circuit 511 for the first side organic EL display sheet 211, a drive circuit 512 for the second side organic EL display sheet 212, a drive circuit 513 for the third side organic EL display sheet 213, and a drive circuit 514 for the fourth side organic EL display sheet 214.

[0045] Although not shown in Figure 3, the watch body 100 also has a power supply unit to supply power to each of the functional blocks shown in Figure 3. Power from the power supply unit and various signals from the display control unit 450 are supplied via the first electrode group 120 (see Figure 2(a)) located on the watch body 100 side and the second electrode groups 220 (see Figure 2(c)) located on each of the organic EL display sheets 210 to 214 sides.

[0046] The display control unit 450 reads an image stored in the image data storage unit 420 based on the content selected by the user from the display image selection unit 410, and controls the display of the read image on each of the organic EL display sheets 210 to 214. At this time, the display control unit 450 controls the display of each of the organic EL display sheets 210 to 214 so that the images displayed on each of the organic EL display sheets 210 to 214 are linked or related.

[0047] As described above, the display control unit 450 controls the display of images read from the image data storage unit 420 on each of the organic EL display sheets 210 to 214. However, when the watch 1 according to Embodiment 1 is started up, it controls the display of a display image selection screen that functions as a display image selection unit 410. When the display image selection screen is displayed on the watch 1, the user can select the content they want to display from the displayed display image selection screen. The display control unit 450 then controls the display based on the display mode selected by the user. Note that the selection of the display image may also be made from the selection screen of the user's smartphone, which is linked to the watch 1.

[0048] For example, if the user selects analog time display from the display image selection unit 410, the five display units 210-214 of the wristwatch 1 according to Embodiment 1 will enter analog clock display mode, and the display control unit 450 will read the current time data from the time data generation unit 440 and control the respective drive circuits 510-514 of each organic EL display sheet 210-214 to display the current time using the hour and minute hands on each organic EL display sheet 210-214. Note that the selection of the display image may also be made from the selection screen of the user's smartphone, which is linked to the wristwatch 1. The specific method of displaying the time in analog time display mode will be described later.

[0049] At least the display control unit 450 and the arithmetic unit 460, which constitute the control system of the watch body 100, perform various processes through the operation of a processing unit, such as a CPU (Central Processing Unit) or a GPU (Graphics Processing Unit). These various processes are performed, for example, by reading computer programs stored in the memory (ROM, RAM, EEPROM, etc.) within the watch body 100. The image data storage unit 420 is also a memory. The memory storing the computer programs may be the image data storage unit 420 or a different storage unit. Furthermore, at least one of the various drive circuits 510 to 514 of the display unit 200 may include a processing unit, such as the CPU or GPU mentioned above.

[0050] As explained in Figure 2, each of the OLED display sheets 210 to 214 is attached to five of the six surfaces that make up the surface of the watch body 100, excluding the bottom surface. Specifically, the top OLED display sheet 210 is attached to the top surface 110 of the watch body 100, the first side OLED display sheet 211 is attached to the first side surface 111 of the watch body 100, the second side OLED display sheet 212 is attached to the second side surface 112 of the watch body 100, the third side OLED display sheet 213 is attached to the third side surface 113 of the watch body 100, and the fourth side OLED display sheet 214 is attached to the fourth side surface 114 of the watch body 100. In this way, when each of the OLED display sheets 210 to 214 is attached to the corresponding surface of the watch body 100, a gap equivalent to the thickness of the OLED display sheet may occur between adjacent OLED display sheets at the corners of the watch body 100.

[0051] Figure 4 is a diagram illustrating how to address gaps that occur between adjacent organic EL display sheets. Figure 4 shows an example of a gap that occurs between the top organic EL display sheet 210 and the third side organic EL display sheet 213.

[0052] As shown in Figure 4, at the corners of the watch body 100, a black material 280 is embedded between adjacent organic EL display sheets (in this case, between the top organic EL display sheet 210 and the third side organic EL display sheet 213). For example, the black material 280 can be made by mixing graphite filler with silicone rubber to create a black color. By filling the gaps between adjacent organic EL display sheets with the black material 280 in this way, the gaps between adjacent organic EL display sheets become less noticeable, resulting in a cleaner and more aesthetically pleasing appearance for the watch 1.

[0053] In Figure 4, only the space between the top organic EL display sheet 210 and the third side organic EL display sheet 213 is shown, but the spaces between the five display sections 210 to 214, namely between the first side organic EL display sheet 211 and the second side organic EL display sheet 212, between the second side organic EL display sheet 212 and the third side organic EL display sheet 213, between the third side organic EL display sheet 213 and the fourth side organic EL display sheet 214, between the fourth side organic EL display sheet 214 and the first side organic EL display sheet 211, and between the top organic EL display sheet 210 and each of the side organic EL display sheets 211 to 214, are also similarly filled with black material 280.

[0054] As a result, the black member 280 is embedded in the corners of the watch body 100, that is, between adjacent organic EL display sheets. Then, a protective member 290 (see Figure 6) is applied and cured to the surface of each organic EL display sheet 210-214 in which the black member 280 is embedded between adjacent organic EL display sheets, so as to cover the entire surface of each organic EL display sheet 210-214.

[0055] Figure 5 is a diagram illustrating the state in which the protective member 290 has been applied and cured to cover the entire wristwatch 1. Note that Figure 5 is a cross-sectional view obtained by cutting the wristwatch body 100 vertically from the top organic EL display sheet 210 to the belt 300 on its lower surface, parallel to the long side of the rectangular wristwatch body 100, and components such as the display control unit 450 located inside the wristwatch body 100 (see the functional block diagram in Figure 3) are omitted from the illustration. As shown in Figure 5, the transparent protective member 290 has been applied and cured to cover the entire five display sections of the wristwatch 1, namely the top organic EL display sheet 210 and each of the first side organic EL display sheets 211 to 214.

[0056] Here, as the protective member 290, a silicone resin having waterproof, corrosion-resistant, and heat-resistant properties can preferably be used. In this way, by applying and curing the transparent protective member 290 so as to cover the entirety of the five display parts of the wristwatch 1, namely the top organic EL display sheet 210 and each of the first side organic EL display sheets 211 to 214, the wristwatch 1 becomes waterproof, corrosion-resistant, and heat-resistant, and is less prone to damage, thus becoming a highly reliable wristwatch.

[0057] The five display units 210 to 214 described above may also be made up of a single organic EL display sheet (not shown). In that case, the single organic EL display sheet is folded to conform to the outer shape of the watch body 100 and attached to the watch body 100. When the five display units 210 to 214 are made up of a single organic EL display sheet, no gap is formed in the folded portion, so it is not necessary to fill the folded portion with a black material. On the other hand, a gap equivalent to the thickness of the organic EL display sheet may be formed at the boundary between adjacent organic EL display sheets, rather than at the folded portion.

[0058] For example, in a single organic EL display sheet having a shape in which a top organic EL display sheet located in the center has first side organic EL display sheets, second side organic EL display sheets, third side organic EL display sheets, and fourth side organic EL display sheets extending outwards in all four directions, the top organic EL display sheet can be attached to the top surface 110 of the watch body 100, and each side organic EL display sheet can be folded to attach each side organic EL display sheet to each side 111 to 114 of the watch body 100. In this case, a gap equivalent to the thickness of the organic EL display sheet may be formed at the corners of each side display section, so it is preferable to fill this gap with a black material.

[0059] Next, we will describe the specific display modes of the wristwatch 1 according to Embodiment 1. The wristwatch 1 according to Embodiment 1 can be worn on either the left or right arm of the user, but here we will describe the case where the wristwatch 1 according to Embodiment 1 is worn on the user's left wrist, as shown in Figure 1.

[0060] [First display mode] The user selects the digital clock display mode from the display image selection unit 410. As a result, the five display units 210 to 214 display the time in digital clock mode, and the current time is displayed on the five display units 210 to 214 of the wristwatch 1. Here, as an example of the time display format, the hours and minutes are each displayed as two-digit numbers.

[0061] Figure 6 is a diagram illustrating the first display mode in the wristwatch 1 according to Embodiment 1. For example, as shown in Figure 6, suppose the current time is displayed as 23:46. Figure 6(a) shows the time display when the wristwatch body 100 is viewed from diagonally above, close to the image sensor 60. Figure 6(b) shows the time display when the wristwatch body 100 is viewed from vertically above the surface of the top organic EL display sheet 210. Figure 6(c) shows the time display when the wristwatch body 100 is viewed from diagonally above, close to the image sensor 50.

[0062] In all of the time displays shown in Figures 6(a), 6(b), and 6(c), the four digits indicating 23:46 are displayed on at least one of the display units 210 to 214 so as far as possible that they face the user.

[0063] For example, in the example shown in Figure 6(a), the time is displayed on the display units 210, 213, and 214 so as to be directly in line with the user's line of sight, which is diagonally above the watch body 100 and close to the image sensor 60. In reality, the surface composed of the display units 210, 213, and 214 is not flat. Therefore, numbers displayed across two or three display units will be bent at the edges or corners of the display units. In Figure 6(a), the number "4" is displayed across display unit 210 and display unit 214. Also, the number "6" is displayed across display unit 210, display unit 213, and display unit 214. Therefore, the numbers "4" and "6" are displayed bent at the edges where the display units meet.

[0064] In the example shown in Figure 6(b), the time is displayed only on the display unit 210, facing directly towards the user's line of sight, which is vertically above the top surface of the watch body 100. Since the time is displayed only on the display unit 210, four digits without any bends are displayed on the display unit 210.

[0065] In the example shown in Figure 6(c), the time is displayed on the display units 210, 212, and 213 so as to be directly facing the user's line of sight, which is located diagonally above the watch body 100 and close to the image sensor 50. In reality, the surface formed by the display units 210, 212, and 213 is not flat. Therefore, numbers displayed across two display units will appear to be bent at the edges or corners of the display units. In Figure 6(c), the number "4" is displayed across display units 210, 212, and 213. Similarly, the number "6" is displayed across display units 210 and 212. Therefore, the numbers "4" and "6" are displayed as bent at the edges where the display units meet.

[0066] As described above, in order to display the time directly in line with the user's line of sight, image sensors 50 and 60 capture an image including a human eye, and the processing unit 460 recognizes the image. Details of the above processing will be described later.

[0067] [Second display mode] Next, the second display mode will be described. Suppose the user selects the analog clock display mode from the display image selection unit 410. As a result, the five display units 210 to 214 will display the outer edge of the clock, a total of four numbers indicating 12, 3, 6, and 9 o'clock, the hour hand, and the minute hand.

[0068] Figure 7 is a diagram illustrating a second display mode in the wristwatch 1 according to Embodiment 1. For example, as shown in Figure 7, suppose the current time is displayed as 10:10. Figure 7(a) shows the time display when the wristwatch body 100 is viewed from diagonally above, close to the image sensor 60. Figure 7(b) shows the time display when the wristwatch body 100 is viewed from vertically above the surface of the top organic EL display sheet 210. Figure 7(c) shows the time display when the wristwatch body 100 is viewed from diagonally above, close to the image sensor 50.

[0069] In all of the time displays shown in Figures 7(a), 7(b), and 7(c), the analog clock display showing 10:10 is shown on at least one of the display units 210 to 214 so as far as possible that it faces the user.

[0070] For example, in the example shown in Figure 7(a), the analog clock is displayed on the display units 210, 213, and 214 so as to be directly in line with the user's line of sight, which is diagonally above the watch body 100 and close to the image sensor 60. In reality, the surface composed of the display units 210, 213, and 214 is not flat. Therefore, the analog clock display is displayed in a bent state at the edges that form the boundaries of each display unit 210, 213, and 214. In Figure 7(a), a portion of the lower area of ​​the analog clock is displayed on the display units 213 and 214.

[0071] In the example shown in Figure 7(b), the analog clock is displayed only on the display unit 210, facing directly towards the user's line of sight, which is vertically above the top surface of the wristwatch body 100. Because the analog clock is displayed only on the display unit 210, it is displayed on the display unit 210 without any bending or distortion.

[0072] In the example shown in Figure 7(c), the analog clock is displayed on the display units 210, 212, and 213 so as to be directly in line with the user's line of sight, which is diagonally above the watch body 100 and close to the image sensor 50. In reality, the surface formed by the display units 210, 212, and 213 is not flat. Therefore, the analog clock display is displayed in a bent state at the edges that form the boundaries of each display unit 210, 212, and 213. In Figure 7(c), a portion of the lower area of ​​the analog clock is displayed on display units 212 and 213.

[0073] As described above, in order to ensure that the analog clock is displayed facing the user directly, image sensors 50 and 60 capture images including the human eye, and processing such as image recognition is performed by the processing unit 460. Details of the above processing will be described later.

[0074] [Third display method] Next, we will explain the third display method. Figure 8 is a diagram illustrating the third display mode of the wristwatch 1 according to the embodiment. The third display mode of the wristwatch 1 according to the embodiment is the same as the second display mode described above, when the five display units 210 to 214 are set to analog clock display mode. However, in the third display mode, unlike the second display mode described above, there are 12 types of numbers representing the time, from "1" to "12", and these are displayed on the respective side organic EL display sheets 211 to 214 located on each side of the wristwatch body 100. In addition, the display unit 210 displays dots (indicated as M in Figure 8) corresponding to the 12 types of numbers representing the time on the circumference of an ellipse or rectangle, and displays the hour hand 230 and minute hand 240 inside. In the third display mode, the time is 1:43.

[0075] In the third display mode of the wristwatch 1 according to Embodiment 1, the display control unit 450 controls the display so that, to the user, it appears as if the inside of the wristwatch body 100 is transparent, and the numbers indicating the time in analog clock display mode are displayed on the side display units 211 to 214. In this case, for the sides that are not visible to the user, the display control unit 450 displays the numbers indicating the time inverted left to right, performing a display process that makes it appear as if the numbers are visible through the inside of the wristwatch body 100. Unlike the first and second display modes, the third display mode does not display the time or clock face-to-face with the user, but rather displays numbers that should not be visible to the user using the sides that are visible to the user, making it appear as if they are transparent. Such a display may also be called a display that makes a three-dimensional image appear on the wristwatch body 100.

[0076] Here, controlling the display of each organic EL display sheet 210 to 214 so that the inside of the watch body 100 is visible means controlling the display so that the watch body 100 appears as if it were a transparent container. For example, according to the display configuration shown in Figure 8(a), the user can visually see the inner sides of the watch body 100 (the inner side 111a of the first side 211 and the inner side 112a of the second side 212), and the inner bottom surface 115a of the watch body 100 is visible to the user. In this case, the "transparent container" may be a colorless transparent container or a colored transparent container that is light-transmitting.

[0077] By performing this type of display control, the user will perceive the inside of the watch body 100 as if it were transparent. In particular, in the display configuration shown in Figure 8(a), the numbers "11," "12," "1," "2," "3," and "4" displayed on the first side display section 211 and the second side display section 212, which are normally invisible to the user, are displayed with the numbers reversed left to right from the user's perspective. As a result, the user will have the impression that the watch body 100 is a transparent container and that the inside of the watch body 100 is visible.

[0078] In the third display embodiment, the hour hand 230 and minute hand 240 are displayed on the top display section 210, which appears transparent to the user. In this case, the minute hand 240 is displayed only on the top display section 210, but it may also be extended and displayed on one of the side display sections 211 to 214.

[0079] The display mode shown in Figure 8(a) shows the time display when the watch body 100 is viewed from an oblique angle above, close to the image sensor 60. This display mode can be realized because the direction from which the user is viewing the watch body 100 is determined. For this purpose, the image sensors 50, 60 and the processing unit 460 are used to capture an image including the human eye and perform image recognition and other processing. Through this processing, the sides of the watch body 100 that are not visible to the user are identified, and the transparent display of those sides can be simulated and displayed on the top and sides visible to the user.

[0080] Figure 8(b) shows the time display when viewed from above, slightly tilted backward along the belt 300, relative to the surface of the organic EL display sheet 210 for the top surface of the watch body 100. In this case, it is necessary to perform display processing on the display unit 210 so that the side display unit 211 appears to be transparent. On the other hand, the side display unit 213 is visible to the user, so the normal display configuration is sufficient. Also, the side display units 212 and 214 are not visible to the user at all, so no display processing is required for them. Such displays can be achieved using the image sensors 50 and 60 and the processing unit 460, as in the case of Figure 8(a).

[0081] Figure 8(c) shows the time display when the watch body 100 is viewed from diagonally above, close to the image sensor 50. According to the display configuration shown in Figure 8(c), the display control unit 450 controls the display units 210, 212, and 213 to display so that the user can see through to the inner sides of the watch body 100 (the inner side 111a of the first side 211 and the inner side 114a of the fourth side 214), and also see through to the inner bottom surface 115a of the watch body 100. Such a display can be achieved using the image sensors 50 and 60 and the calculation unit 460, as in the case of Figure 8(a).

[0082] Thus, in the third display embodiment, the inside of the watch body 100 appears transparent to the user, and the numerical display of the time in analog clock display mode is displayed correctly left to right on the side visible to the user, and reversed left to right on the side not visible to the user, using the side visible to the user. For this reason, the watch 1 according to Embodiment 1 is a watch with unprecedented new value. On the side not visible to the user, the numerical display of the time and other displays in analog clock display mode may be omitted, but to avoid causing discomfort to people other than the user when they see the watch, the numerical display of the time may be displayed correctly left to right for people other than the user. Details of the above processing will be described later.

[0083] [Fourth display mode] Figure 9 is a diagram illustrating the fourth display mode of the wristwatch 1 according to Embodiment 1. The fourth display mode is the mode when the five display units 210 to 214 are set to digital clock display mode. Here, digital clock display mode means a display mode in which the time is displayed numerically, similar to the first display mode, rather than being represented by hour and minute hands. Furthermore, in the fourth display mode, an example is described in which not only the time but also the date, day of the week, and other information are displayed. To display such information, the user can set the five display units 210 to 214 to digital clock display mode by selecting, for example, "digital clock display" from the display image selection screen, which functions as a display image selection unit 410.

[0084] By setting the five display units 210-214 to digital clock display mode, for example, as shown in Figure 9, the top display unit 210 can display the current time, such as 10:25:34, as "10:25:34", as well as today's date, such as October 1, 2020, as "20.10.01", and today's day of the week as "Thursday". Furthermore, other information, such as today's weather forecast, can be displayed on each side display unit 211-214 (the side in the example in Figure 9) using weather symbols. This various information can also be displayed in a scrolling manner across each display unit. For example, it is possible to display the day of the week in a scrolling manner, followed by various other pieces of information.

[0085] Unlike the first display mode, the fourth display mode does not display the time or other information directly facing the user. In the fourth display mode, the display format is rotated in 90-degree increments within the plane of the display unit 210 so that the user can view the time and other information in a horizontal format as much as possible, and the weather information is displayed on the side located directly below the time and other information display surface.

[0086] Figure 9(a) shows the time display when the watch body 100 is viewed from an oblique angle above, close to the image sensor 60. This display configuration is possible because the direction from which the user is viewing the watch body 100 is determined. For this purpose, the image sensors 50, 60 and the calculation unit 460 are used to capture an image including the human eye and perform image recognition processing. As a result, the time and other information are displayed in a way that is approximately parallel to the long side of the rectangular display unit 210 and is not upside down, allowing for normal viewing from the user's line of sight. This is because a display parallel to the long side is easier for the user to see than a display parallel to the short side. The weather is displayed in the display unit 214, which is located directly below the time and other information on the display unit 210. When the watch body 100 is viewed from an oblique angle above, close to the image sensor 60, the display control unit 450 uses the image sensors 50, 60 and the calculation unit 460 to determine the direction from which the user is viewing the display unit 210 of the watch 1, and determines the display configuration of the time and other information on the display units 210 to 214. Details of this will be described later.

[0087] Figure 9(b) shows the time display when viewed from above, slightly tilted backward along the belt 300 relative to the surface of the organic EL display sheet 210 for the top surface of the watch body 100. In this case, the time and other information are displayed on the rectangular display unit 210, approximately parallel to the shorter side of the display unit 210. The processing of the display control unit 450, etc., is the same as in the case of Figure 9(a).

[0088] Figure 9(c) shows the time display when the watch body 100 is viewed from an oblique angle above, close to the image sensor 50. Similar to Figures 9(a) and 9(b), the image sensors 50, 60 and the processing unit 460 are used to capture images including the human eye and perform image recognition and other processing. As a result, the time and other information are displayed in a way that is approximately parallel to the long side of the rectangular display unit 210 and is not upside down, allowing for normal viewing from the user's line of sight. The weather is displayed in the display unit 212, which is located directly below the time and other information displayed in the display unit 210. When the watch body 100 is viewed from an oblique angle above, close to the image sensor 50, the display control unit 450 uses the image sensors 50, 60 and the processing unit 460 to determine the direction of the user's line of sight when viewing the display unit 210 of the watch 1, and determines the display mode of the time and other information in the display units 210 to 214. Details of the above processing will be described later.

[0089] Thus, in the fourth display embodiment, various types of information, including a digital clock display, can be displayed as images using the five display units 211 to 214, and it is also possible to display some of the information (images) or all of the information (images) in a flowing manner. As described above, the wristwatch 1 according to Embodiment 1 can realize image display that responds to the user's gaze, making it a wristwatch with unprecedented new value.

[0090] [Method for determining the direction in which the user views their watch] Next, a method for determining the direction in which the user of the wristwatch 1 according to Embodiment 1 will be viewed will be described.

[0091] Figure 10 is a diagram illustrating how the user of the wristwatch 1 according to Embodiment 1 determines the direction in which they view the wristwatch 1. The wristwatch 1 according to Embodiment 1 uses two image sensors 50, 60 and a processing unit 460 to determine the distance and direction between the user's eye and the in-plane center of the wristwatch's display unit 210.

[0092] The following describes a method for determining the distance and direction between the user's eyes and the in-plane center of the watch's display unit 210 using two image sensors 50 and 60. Figure 10(a) shows a three-dimensional space with image sensor 60 (let's call it point A) as the origin, the display surface 210 as the XY plane, and the direction perpendicular to the display surface 210 as the Z axis. Image sensor 50 (let's call it point B) is assumed to be located on the X axis. When image sensor 60 captures an image of the user, the processing unit 460 can recognize both eyes from the user's image. Specifically, the processing unit 460 uses a trained model in the image data storage unit 420 to recognize the position of the person's face and eyes in the image. As a result, in three-dimensional space, the direction D2 from point A on image sensor 60 to the midpoint M of the line segment connecting the user's eyes is determined. However, only the direction D2 can be determined from the image captured by image sensor 60.

[0093] Next, when the image sensor 50 captures an image of the user, the processing unit 460 can recognize both eyes from the user's image, similar to the image captured by the image sensor 60. The use of the trained model is the same as when analyzing the image captured using the image sensor 60. As a result, in three-dimensional space, the direction D3 from point B on the image sensor 60 to the midpoint M in the line segment connecting the user's eyes is identified. Once the two directions D2 and D3 are identified, the processing unit 460 determines the coordinates of point M where these directions intersect. The distance between point A and point B corresponds to the length of the shorter side of the display unit 210. Since the distance L2 between point A and point M, the distance L3 between point B and point M, and directions D1 and D2 are also identified, a triangle ABM tilted at a certain angle from the display unit 210 can be identified.

[0094] Figure 10(b) is a diagram illustrating the direction and distance between the midpoint M of the line segment connecting the user's eyes and the center C of the display unit 210. Figure 10(c) is a view from a position close to the watch 1, with the watch 1 omitted from Figure 10(b). Once triangle ABM and the angle θ that triangle ABM makes with the display unit 210 are determined, the direction D4 from point M toward the center C of the display unit 210 and the distance L4 between M and C are also uniquely determined. This is because the positional relationship between the center C and point A (or point B) is fixed. The above calculation is performed by the calculation unit 460. In this way, once the direction and distance from the midpoint M to the center C of the display unit 210 are determined, the display control unit 450 of the watch 1 transmits a signal to the drive circuits 510-514 to display according to the direction of the user's line of sight.

[0095] To perform the display control by the display control unit 450 described above, the distance L4 between M and C is not essential. It is sufficient to be able to specify only the direction D4 from point M toward the center C of the display unit 210. However, by specifying the distance L4, the following advantages can be enjoyed. The watch 1 can be controlled to remain in a black state without displaying anything if the distance L4 exceeds a certain threshold (e.g., 800 mm), while displaying the time, etc., on the display units 210-240 of the watch 1 if the distance L4 is less than or equal to the threshold (e.g., 800 mm). Such control is necessary to prevent the time, etc., from being displayed when someone who happens to be near the watch 1 glances at it while it is on a desk, and to ensure that the time, etc., is displayed only when the user wearing the watch 1 on their wrist looks at it. The threshold described above is not limited to 800 mm, but can be set to another distance, such as 500 mm or 1200 mm. The threshold may be stored, for example, in the image data storage unit 420. The display control unit 450 or the calculation unit 460 can read a threshold value stored in the image data storage unit 420 and compare it with the distance L4 between the MCs. The threshold value may not be set by the user, or it may be set freely by the user using a setting means such as the display image selection unit 410.

[0096] In addition, instead of switching between display and non-display on the display units 210-214 based on the magnitude of the distance L4, the display and non-display may be switched according to the distance L2 from the image sensor 60 to the midpoint M, the distance L3 from the image sensor 50 to the midpoint M, or the sum of distance L2 and distance L3. Alternatively, the eye position E1 or position E2 may be used instead of the midpoint M. As a variation, if only one eye is detected from the user's image, instead of specifying the coordinates of the midpoint M, the position of the detected eye (for example, E2) may be specified to specify triangle ABE2 (including the angle θ between triangle ABE2 and the display unit 210).

[0097] The above-described embodiment is an embodiment of a wristwatch 1 equipped with a detection unit including two image sensors 50, 60, but the number of image sensors is not limited to two. For example, in a modified wristwatch 1, the detection unit may include one or more image sensors installed in any part of the wristwatch 1, and a calculation unit that extracts information regarding the positional relationship between the user's eye and the wristwatch 1 from the image of the user's eye captured by the one or more image sensors. As a result, the calculation unit can extract information regarding the positional relationship between the user's eye and the wristwatch 1 as positional information for the wristwatch 1. For example, in a wristwatch 1 equipped with only one image sensor, the direction from the user's eye toward a predetermined position on the top display unit 210 of the wristwatch 1 (for example, the center of the top display unit 210) can be determined, but the distance between the user's eye and the predetermined position on the top display unit 210 cannot be determined. However, if the above direction can be determined, the orientation of the image displayed on the display units 210-214 can be determined according to the above direction. On the other hand, by providing three or more image sensors, the direction and distance from the user's eye to a predetermined position on the top display section 210 of the wristwatch 1 can be determined even more accurately than in the example using the two image sensors 50 and 60 described above.

[0098] The number of image sensors may be reduced from one or more to four. Preferably, the four image sensors can be installed near the vertices where adjacent sides of the four sides of the watch 1 meet the top surface of the watch 1. By arranging the four image sensors in this position, if the user's eyes are in a direction that is difficult to image with the aforementioned image sensors 50 and 60, the position of the eyes can be easily imaged using the two image sensors other than image sensors 50 and 60. As a variation, the four image sensors may be installed only on the belt 300 connected to the watch 1, or two may be installed at each connection point between the watch body 100 and the belt 300. Furthermore, if one image sensor is placed at each of the four corners of the top display section 210, the level of image interpolation will be lower compared to when one image sensor is placed at each of the four corners, but the level of interpolation will be higher compared to when two image sensors 50 and 60 are placed. Alternatively, two of the three image sensors may be placed at the two corners of the top display unit 210, and the remaining image sensor may be placed at the connection point between the watch body 100 and the strap 300.

[0099] (Embodiment 2) Next, Embodiment 2 of the present invention will be described. In Embodiment 2, components common to Embodiment 1 are denoted by the same reference numerals, and their descriptions may be omitted.

[0100] Figure 11 shows the wristwatch 1 according to Embodiment 2 being worn on the user's left arm. In Figure 11, arrow A indicates the direction of the user's line of sight when viewing the wristwatch 1 worn on the left wrist, as in Embodiment 1. In Figure 11, arrow A is depicted as being in a horizontal plane, but in reality, the direction of the line of sight is generally directed diagonally downward from the user's eyes.

[0101] In the wristwatch 1 according to Embodiment 2, the display units 210 to 214 are black when not in use, and a digital clock is displayed on the display units 210 to 214 when in use. In the example in Figure 11, only the display unit 210 shows a total of four numbers: "2", "3", "4", and "6", indicating 23:46.

[0102] Figure 12 is a functional block diagram showing the configuration of the control system for operating the wristwatch 1 according to Embodiment 2. The functional block diagram in Figure 12 primarily shows the functional blocks necessary for displaying information, among the various functions of the wristwatch 1 according to Embodiment 2. The detection unit provided in the wristwatch 1 according to Embodiment 2 includes a three-dimensional acceleration sensor for detecting the posture information of the wristwatch 1, and can detect information regarding the three-dimensional posture of the wristwatch 1 as posture information. Furthermore, the detection unit is also a three-dimensional acceleration sensor for detecting movement information of the wristwatch 1, and can detect information regarding the three-dimensional movement of the wristwatch 1 as movement information. Hereinafter, the functions specific to Embodiment 2 will be described with reference to Figure 12, and redundant explanations of functions common to Embodiment 1 will be omitted.

[0103] The watch body 100 includes the same components as in Embodiment 1, such as the display image selection unit 410, image data storage unit 420, synchronization signal generation unit 430, time data generation unit 440, and display control unit 450, as well as a three-dimensional acceleration sensor (hereinafter simply referred to as "accelerometer") 610. The components of the display unit 200 are the same as in Embodiment 1. The acceleration sensor 610 is a type of inertial sensor capable of measuring acceleration and can detect three-dimensional inertial motion. The acceleration sensor 610 can detect the movement of the watch 1 corresponding to the movement of the user's arm, and can also detect whether the display unit 210 of the watch 1 is holding a horizontal or nearly horizontal angle. In this embodiment, the acceleration sensor 610 also includes a calculation unit. The calculation unit is the part that performs calculations using a processing unit such as a CPU or GPU. The same applies to the "calculation unit" referred to hereafter. The watch body 100 may also include a device that integrates the acceleration sensor 610 and a gyro sensor. It may also further include a geomagnetic sensor. The image data storage unit 420 stores various image data, as well as acceleration thresholds and various computer programs. The display control unit 450 refers to the thresholds in the image data storage unit 420 and can switch the display on the display units 210 to 214 depending on whether the acceleration of the wristwatch 1 exceeds the threshold or does not, according to the movement of the user's arm.

[0104] [First display mode] Figure 13 is a diagram illustrating the first display mode of the wristwatch 1 according to Embodiment 2. When the user performs the action of looking at the wristwatch, and the acceleration sensor 610 inside the wristwatch 1 detects an acceleration that exceeds a preset threshold, the display state a before detection switches to a state in which each digit indicating the time rotates alternately between state b, where the digits rotate in a predetermined direction (see the direction of the arrows around the digits), and state c, where they rotate in the opposite direction (see the direction of the arrows around the digits). Specifically, when the acceleration received from the acceleration sensor 610 exceeds a threshold stored in the image data storage unit 420, the display control unit 450 causes each drive circuit 510 to 514 to vibrate the four digits that make up the current time 252 displayed on the display unit 210, etc. To perform such a display, the user selects, for example, "Other display modes" from the display image selection screen, which functions as a display image selection unit 410, and then selects, for example, "Time vibration pattern" from among the multiple options in "Other display modes". The vibration images of the digits are stored in the image data storage unit 420. Furthermore, the four digits that make up the current time 252 may vibrate not only within the display unit 210 but also extending beyond the display units 211 to 214.

[0105] The image data storage unit 420 stores a computer program programmed to return the display to the original display state a when a predetermined time has elapsed since the acceleration detected by the acceleration sensor 610 exceeded a threshold and the display started to vibrate the numbers. The display control unit 450 measures the time elapsed since the start of vibration, and when a predetermined time has elapsed (for example, 30 seconds), it switches the vibrating display state, which alternates between display state b and display state c, back to the original display state a where the numbers do not vibrate, according to the computer program.

[0106] [Second display mode] Figure 14 is a diagram illustrating a second display mode of the wristwatch 1 according to Embodiment 2. The second display mode is set by the user specifying a mode from the display image selection unit 410. In the initial state of the second display mode, the current time 252 is displayed on the top display unit 210. However, if acceleration is applied to the wristwatch 1, for example, by the user's arm moving, the current time 252 will move and protrude to the side. To enable this display, the user selects, for example, "Other display modes" from the display image selection screen, which functions as the display image selection unit 410, and then selects, for example, "Time display protrusion pattern" from among the multiple options in "Other display modes". In the wristwatch 1 according to Embodiment 2, the display control unit 450 sends signals to each of the drive circuits 510 to 514 and controls the display of each of the five display units 210 to 214 so that the current time 252 moves when the acceleration when the wristwatch 1 is brought close to the user's hand exceeds a threshold value stored in advance in the image data storage unit 420.

[0107] Furthermore, when the current time 252 is projected to the side, the side to which it is projected may be pre-programmed, or the display may be projected onto the organic EL sheet on the side visible to the user, depending on the tilt measured by the acceleration sensor 610.

[0108] Figure 15 shows a series of movements in which the current time extends not only to the top display unit 210 but also to one or more of the side display units 211 to 214 in a pre-programmed display mode. As shown in Figure 15, the four digits that make up the current time extend not only to the top display unit 210 but also to the four side displays, changing their display mode from a to h in the figure. After changing from a to h, the program may terminate, or it may return to a and change to h again. Such display operations are described in a computer program stored in the image data storage unit 420.

[0109] [Third display method] Figure 16 is a diagram illustrating a third display mode of the wristwatch 1 according to Embodiment 2. The third display mode is a display mode in which a collection of small spheres 262 within the rectangular wristwatch body 100 physically behaves in response to the movement of the user's arm. When the user looks at the wristwatch 1, the small spheres 262 come together and change into a time display. That is, in this display mode, initially, the small spheres 262 are shown dispersed and moving randomly within the rectangular wristwatch body 100, and then, as time passes, the small spheres 262 come together on the top surface to form the current time 252. To display in this way, the user selects, for example, "Other display modes" from the display image selection screen which functions as a display image selection unit 410, and then selects, for example, "Pattern of small spheres" from among the multiple options in "Other display modes". When the acceleration sensor 610 detects the acceleration of the watch body 100 and / or the tilt of the top display unit 210 in response to the user's arm movement, the display control unit 450 displays a number of small spheres 262 moving within the watch body 100 based on the detected conditions. The small spheres 262 may move, for example, in accordance with the passage of time, or in accordance with the user's arm movement. The display in which the small spheres 262 form the current time 252 may switch from the previous random movement display when the acceleration sensor 610 stops detecting acceleration. In that case, when the acceleration from the acceleration sensor 610 becomes zero or below a predetermined threshold, the display control unit 450 receives the signal, reads the computer program in the image data storage unit 420, and can switch to the display of the current time 252 using the small spheres 262. Specifically, the display control unit 450 sends signals to each drive circuit 510 to 514 to enable the above-described display mode and controls the display of each of the five display units 210 to 214.

[0110] [Fourth display mode] Figure 17 is a diagram illustrating the fourth display mode of the wristwatch 1 according to Embodiment 2. The fourth display mode is a mode in which the frame of the wristwatch body 100 itself vibrates based on the acceleration of the user looking at the wristwatch 1, producing an illusionary visual effect. That is, as shown in Figure 17, in the fourth display mode, the current time 252 is displayed on the top display unit 210 in the initial state, but when acceleration is applied to the wristwatch 1, for example, by the movement of the arm, the pseudo-wristwatch frame 264 inside the wristwatch 1 appears to vibrate (an optical illusion display mode) triggered by that movement. To enable such a display, the user selects, for example, "Other display modes" from the display image selection screen which functions as a display image selection unit 410, and then selects, for example, "Vibrating pattern" from among the multiple options in "Other display modes". In the wristwatch 1 according to Embodiment 2, the display control unit 450 controls the display of each of the five display units 210 to 214 so that the above-described display modes are possible. The image data storage unit 420 stores a pseudo-wristwatch frame 264 (consisting of multiple frames) which switches from the current time 252 display on the top display unit 210, a predetermined threshold for acceleration, and a computer program for switching from the normal time display to the display of the pseudo-wristwatch frame 264 when an acceleration signal exceeding the predetermined threshold is obtained.

[0111] When the display control unit 450 receives an acceleration signal from the acceleration sensor 610 that exceeds a predetermined threshold, it reads the computer program in the image data storage unit 420 and sends signals to each drive circuit 510 to 514, switching the display of the current time 252 to the display of the pseudo-wristwatch frame 264. The data for each display image is read from the image data storage unit 420 by the display control unit 450. The computer program may also be configured to switch from the display of the pseudo-wristwatch frame 264 back to the original display of the current time 252 after a predetermined time has elapsed since detecting acceleration exceeding the predetermined threshold.

[0112] [Fifth display mode] Figure 18 is a diagram illustrating a fifth display mode of the wristwatch 1 according to Embodiment 2. As shown in Figure 18, the fifth display mode displays the wristwatch 1 with a ribbon 254 wrapped around it. In this display mode, the ribbon 254 may be wrapped around the wristwatch or unwrapped as time progresses, for example, every second. To enable such a display, the user selects, for example, "Other display modes" from the display image selection screen, which functions as a display image selection unit 410, and then selects, for example, "Ribbon wrapping pattern" from among the multiple options in "Other display modes". The fifth display mode can be realized by switching the normal display of the current time 252 to a ribbon 254 wrapping display when the acceleration detected by the acceleration sensor 610 exceeds a threshold (referred to as the second threshold) that is larger than the predetermined threshold in the first to fourth display modes. The image data storage unit 420 stores a ribbon-wrapped time display frame, a second acceleration threshold, and a computer program for switching from the normal time display to the ribbon-wrapped time display frame display when an acceleration signal exceeding the second threshold is detected. The computer program may also be configured to switch from the ribbon-wrapped time display frame display back to the original current time 252 display after a predetermined time (for example, 3 minutes) has elapsed since detecting acceleration exceeding the second threshold.

[0113] When the display control unit 450 receives an acceleration signal from the acceleration sensor 610 that exceeds the second threshold, it reads the computer program in the image data storage unit 420 and sends signals to each drive circuit 510-514, switching the display of the current time 252 to a ribbon-wrapped time display frame. The data for each display image is read from the image data storage unit 420 by the display control unit 450.

[0114] Figure 19 is a diagram illustrating a modified example of the fifth display mode of the wristwatch 1 according to Embodiment 2. This modified example shows a display in which the ribbon 254 is wrapped around the wristwatch 1 while the current time 252 is displayed on the top display unit 210. Such display control can be realized by the same control method as described above with reference to Figure 18. As a modified example, when the acceleration does not exceed the second threshold, as shown in Figure 18, the display shows the ribbon 254 being wound up in seconds while the current time 252 is not displayed, whereas when the acceleration exceeds the second threshold, as shown in Figure 19, the display shows the ribbon 254 being wound up in seconds while the current time 252 is displayed.

[0115] [Sixth display method] Figure 20 is a diagram illustrating the sixth display mode of the wristwatch 1 according to Embodiment 2. As shown in Figure 20, the sixth display mode displays the appearance of fine particles 256 seeping from the top surface to the bottom surface of the wristwatch 1. In this display mode, the surface color may periodically change as fine particles 256 of a different color seep in. To enable such a display, the user selects, for example, "Other display modes" from the display image selection screen, which functions as a display image selection unit 410, and then selects, for example, "Seeping pattern" from among the multiple options in "Other display modes". This enables the wristwatch 1 to display the eighth display mode. The sixth display mode can be achieved by switching from displaying only the current time 252 to displaying fine particles 256 seeping towards the bottom surface on the side display units 211-214 while keeping the current time 252 displayed on the top display unit 210, when the acceleration detected by the acceleration sensor 610 exceeds the second threshold. The image data storage unit 420 stores a video of fine particles 256 permeating, a second acceleration threshold, and a computer program for switching from the normal time display to a display of fine particles 256 permeating when an acceleration signal exceeding the second threshold is detected. The computer program may also be configured to switch from the display of fine particles 256 permeating to the original current time 252 display after a predetermined time (for example, 3 minutes) has elapsed since detecting acceleration exceeding the second threshold.

[0116] When the display control unit 450 receives an acceleration signal from the acceleration sensor 610 that exceeds the second threshold, it reads a computer program from the image data storage unit 420 and sends a signal to each drive circuit 510-514, switching the display of the current time 252 to a display of fine particles 256 seeping in. When the colors of the top display unit 210 and the side display units 211-214 are to be changed periodically, the display control unit 450 reads a computer program containing the above description from the image data storage unit 420 and instructs each drive circuit to change the color. In addition, the data required for display is read from the image data storage unit 420 by the display control unit 450.

[0117] [7th Display Mode] Figure 21 is a diagram illustrating the seventh display mode of the wristwatch 1 according to Embodiment 2. As shown in Figure 21, the seventh display mode displays the liquid as if it were in a transparent container, and the liquid is shown sloshing around and increasing or decreasing within the transparent container. To display this, the user selects, for example, "Other display modes" from the display image selection screen, which functions as a display image selection unit 410, and then selects, for example, "Liquid pattern" from among the multiple options within "Other display modes". As a result, the wristwatch 1 displays the eighth display mode.

[0118] The image data storage unit 420 stores data for displaying the liquid 265 in the transparent container, and a computer program for changing the form of the liquid 265 in the transparent container and displaying it on the display units 210-214 according to the signal from the acceleration sensor 610 and the passage of time. The display control unit 450 reads the computer program from the image data storage unit 420 based on the signal received from the acceleration sensor 610, and sends signals to each drive circuit 510-514 to display the liquid 265 in accordance with the horizontal position and movement of the wristwatch 1. In Figure 21, the top display unit 210 is tilted in the direction of the thick arrow, so the liquid 265 is shifted towards the display unit 213. Also, because the wristwatch 1 has moved in the direction of the thick arrow, the liquid 265 is displayed as wavy.

[0119] Furthermore, the liquid 265 can be displayed as increasing as the current time 252 elapses. This display is also realized by the control of the display control unit 450. Specifically, the display control unit 450 reads the computer program in the image data storage unit 420 based on the time signal and sends signals to each drive circuit 510 to 514 to display the liquid 265 gradually increasing according to the time.

[0120] Thus, the display control unit 450 controls the change in the position of the liquid 265 in the watch body 100 based on the acceleration from the acceleration sensor 610, and the change in the amount of liquid 265 based on the time. As a modification, both the change in the position and amount of liquid 265 may be controlled to depend only on the time, without relying on the signal from the acceleration sensor 610. In that case, the liquid 265 will be displayed as swaying in a pre-programmed motion within the transparent container and increasing as time progresses. On the other hand, both the change in the position and amount of liquid 265 may be controlled to depend only on the acceleration sent from the acceleration sensor 610, without relying on the time. In that case, the liquid 265 will be displayed as swaying in the transparent container in accordance with the tilt and acceleration of the watch body 100.

[0121] [8th display mode] Figure 22 is a diagram illustrating the eighth display mode of the wristwatch 1 according to Embodiment 2. As shown in Figure 22, the eighth display mode is a display mode in which different flows with different flow directions 266 are generated on each display surface (top display section 210 and four side display sections 211 to 214), and these flows change randomly, for example, every second. The top display section 210 also displays the current time 252. However, it is not necessary to display the current time 252. In this display mode, high-speed flows with different directions are generated on each surface of the display sections 210 to 214. That is, each surface is divided by the direction of the flow. To display in this way, the user selects, for example, "Other display modes" from the display image selection screen, which functions as a display image selection section 410, and then selects, for example, "Flow pattern" from among the multiple options in "Other display modes". As a result, the wristwatch 1 displays in the eighth display mode.

[0122] Figure 22 shows an example where the flow display mode repeats between state a and state b every second. However, the switching between state a and state b is not limited to every second, but can be arbitrarily changed to every two seconds or every ten seconds. To perform the above-described display mode, the display control unit 450 controls each display unit 210 to 214 to display the flow based on a time signal. The flow image is stored in the image data storage unit 420. The display control unit 450 reads the flow image from the image data storage unit 420 while reading the computer program in the image data storage unit 420, and sends a signal to each drive circuit 510 to 514 to display the image.

[0123] As a variation, the flow display mode may change based on a signal from the acceleration sensor 610. The image data storage unit 420 stores image data of multiple types of flow, an acceleration threshold for switching flow images, and a computer program for randomly selecting one type of flow image from the multiple types of flow images when the acceleration exceeds the threshold. When the acceleration received from the acceleration sensor 610 exceeds the threshold stored in advance, the display control unit 450 randomly selects flow image data from the image data storage unit 420, sends a signal to the drive circuits 510-514, and switches from displaying the current flow image to displaying the new flow image.

[0124] As described above, the wristwatch 1 according to Embodiment 2 can execute or change the display of the display units 210-214 using information from the acceleration sensor 610, thus providing a wristwatch with unprecedented new value.

[0125] (Embodiment 3) Next, Embodiment 3 of the present invention will be described. In Embodiment 3, components common to the previously described embodiments are denoted by the same reference numerals, and their descriptions may be omitted.

[0126] The detection unit provided in the wristwatch 1 according to Embodiment 3 is a pulse meter (or heart rate monitor), thermometer, blood pressure monitor, electrocardiograph, or 3D accelerometer that detects health-related information (information including health information and fitness information) of the user of the wristwatch 1. The detection unit can detect the user's pulse (or heart rate), body temperature, blood pressure, or activity information as health-related information of the user of the wristwatch 1. Here, "activity information" means information about the user's behavior. Examples of activity-related information include the number of steps taken, the distance walked, the number of floors climbed, the number of calories burned, the number of hours sat in a chair, the number of hours sat in a chair continuously, the number of hours swam, the time when woke up and went to bed, what was eaten, the number of hours slept, the time when went to bed and woke up, the number of calories consumed, time zone information, the number of hours movies watched, the number of hours TV watched, the number of hours books read, the number of hours worked, handwashing information, contact tracing information, breathing information, music and podcasts listened to, and emergency SOS information.

[0127] Figure 23 shows the main part of the wristwatch 1 according to Embodiment 3 as viewed from its underside. The surfaces of the wristwatch 1 other than the underside are the same as in Embodiment 2 (see Figure 11). In Embodiment 3, the belt 300 corresponding to the underside of the wristwatch body 100 has two through holes that penetrate in the thickness direction of the belt 300. One of these through holes is a circular hole when viewed from the underside of the belt 300 (the upper surface in Figure 23). The other through hole is a rectangular hole. The light-emitting and light-receiving unit 621 necessary for measuring blood pressure, pulse, and electrocardiogram is provided in the wristwatch body 100 and is exposed to the outside through the aforementioned circular hole, enabling light emission toward the user's wrist and light reception from the wrist direction. The body temperature sensor 622 is a rectangular parallelepiped sensor provided in the wristwatch body 100 and is exposed from the underside of the belt 300 through the aforementioned rectangular hole.

[0128] Figure 24 is a functional block diagram showing the configuration of the control system for operating the wristwatch 1 according to Embodiment 3. The functional block diagram in Figure 24 primarily shows the functional blocks necessary for displaying information, among the various functions of the wristwatch 1 according to Embodiment 3. Hereinafter, the functions specific to Embodiment 3 will be described with reference to Figure 24, and redundant explanations of functions common to the aforementioned embodiments will be omitted.

[0129] The wristwatch body 100 includes, in addition to the various components similar to those in Embodiment 2, such as the display image selection unit 410, image data storage unit 420, synchronization signal generation unit 430, time data generation unit 440, display control unit 450, and acceleration sensor 610, it also includes a light-emitting / light-receiving unit 621, a body temperature measurement sensor 622, a blood pressure measurement unit (may be called a blood pressure monitor) 630, a pulse measurement unit (may be called a pulse meter) 640, an electrocardiogram measurement unit (may be called an electrocardiograph) 660, and a body temperature measurement unit (may be called a thermometer) 670. In this embodiment, the acceleration sensor 610, blood pressure measurement unit 630, pulse measurement unit 640, electrocardiogram measurement unit 660, and body temperature measurement unit 670 also include calculation units. The light-emitting / light-receiving unit 621 is equipped with, for example, a diode for light emission and a diode for light reception. The body temperature measurement sensor 622 is, for example, a highly sensitive sensor that measures heat flux from the skin surface of the user's wrist. The values ​​measured by the sensor are converted into core body temperature using a specific algorithm. In addition to selecting acceleration measurement, the display image selection unit 410 also allows selection of health-related information such as blood pressure measurement, pulse rate measurement, electrocardiogram measurement, and body temperature measurement. When the user selects one of the above measurements from the display image selection unit 410, the wristwatch 1 can display various information according to the selection. Details of the various displays will be described later.

[0130] At least the display control unit 450, acceleration sensor 610, blood pressure measurement unit 630, pulse measurement unit 640, electrocardiogram measurement unit 660, and body temperature measurement unit 670 of the watch body 100 perform various processes through the operation of a processing unit such as a CPU or GPU. These various processes are performed, for example, by reading computer programs stored in the memory (ROM, RAM, EEPROM, etc.) within the watch body 100. The memory storing such computer programs may also serve as the image data storage unit 420, or it may be a separate storage unit. At least one of the various drive circuits 510 to 514 of the display unit 200 may include a processing unit such as the CPU or GPU mentioned above. Below, among the health or fitness information of the user of the watch 1, an example of a watch 1 equipped with a blood pressure monitor, pulse meter, electrocardiogram, and thermometer as detection units will be described with reference to the drawings. Next, the detection and display of activity-related information (including fitness information) using a three-dimensional acceleration sensor will be described.

[0131] [First display mode] Figure 25 is a diagram illustrating the first display mode of the wristwatch 1 according to Embodiment 3. The first display mode, as shown in Figure 25, displays the user's blood pressure. Figure 25(a) shows an example of the display when the user's blood pressure is normal. Figure 25(b) shows an example of the display when the user's blood pressure is outside the normal range, i.e., abnormal. When measuring blood pressure, the user selects, for example, "Other display modes" from the display image selection screen, which functions as the display image selection unit 410, and then selects, for example, "Blood pressure measurement" from among the multiple options in "Other display modes". This enables blood pressure measurement. When the user selects the blood pressure measurement mode, the blood pressure measurement unit 630 starts measuring blood pressure after a predetermined time has elapsed since the user's selection instruction (for example, 10 seconds later). When measuring blood pressure, the green light-emitting diode in the light-emitting / receiving unit 621 emits light towards the user's wrist. This utilizes the mechanism by which blood reflects green wavelength light. The reflection of light differs depending on whether the blood flow in the blood vessels is high or low due to the heart beating. As the light-receiving diode receives reflected light over time, the blood pressure measurement unit 630 measures blood pressure based on the differences in light reflection. The blood pressure measurement unit 630 can control the emission and reception of light to the light-emitting / receiving unit 621. When blood pressure measurement is complete, the blood pressure measurement unit 630 sends the blood pressure data to the display control unit 450. The display control unit 450 reads the image data for blood pressure display from the image data storage unit 420 according to the computer program in the image data storage unit 420, and sends signals to each drive circuit 510 to 514 to cause the display units 210 to 214 to display the blood pressure.

[0132] In this example of display configuration, blood pressure is visually displayed not only as numerical values ​​for systolic and diastolic blood pressure, but also in a display configuration 267 of an annular region 268 and its internal region 269. When the user's blood pressure is within the normal range, the annular region 268 and internal region 269 are displayed within the range of the top display unit 210, as shown in Figure 25(a). On the other hand, when the user's blood pressure is abnormal, the annular region 268 and / or internal region 269 become larger and are displayed, for example, overflowing into the side display units 212 and 214. When the systolic blood pressure is abnormal and the diastolic blood pressure is normal, only the annular region 268 is displayed, for example, overflowing into the side display units 212 and 214. Also, when the systolic blood pressure is normal and the diastolic blood pressure is abnormal, only the internal region 269 is displayed, for example, overflowing into the side display units 212 and 214. Furthermore, if both the systolic and diastolic blood pressure are abnormal, the annular region 268 and the internal region 269 will both extend beyond the side display units 212 and 214, as shown in Figure 25(b). The display control unit 450 receives image data from the image data storage unit 420 according to the blood pressure received from the blood pressure measurement unit 630 and displays the corresponding blood pressure on the display units 210 to 214. Alternatively, instead of the above display configuration, the color of each region 268 and 269 may be changed without changing the size of the annular region 268 and the internal region 269. For example, if the blood pressure is normal, the color of each region 268 and 269 can be set to green or blue, and if it is abnormal, the color of each region 268 and 269 can be set to red. Furthermore, both the size and color of each region 268 and 269 may be changed.

[0133] [Second display mode] Figure 26 is a diagram illustrating a second display mode of the wristwatch 1 according to Embodiment 3. As shown in Figure 26, the second display mode displays the user's pulse rate. To measure the pulse rate, the user selects, for example, "Other display modes" from the display image selection screen, which functions as a display image selection unit 410, and then selects, for example, "Pulse measurement" from among several options in "Other display modes". This enables pulse measurement. When the user selects the pulse measurement mode, the pulse measurement unit 640 emits light from the light-emitting / light-receiving unit 621 after a predetermined time has elapsed since the user's selection instruction (for example, 10 seconds later), and detects the pulse rate through the blood vessels in the user's wrist. Hemoglobin in the blood has the property of easily absorbing green light. The light-receiving diode receives reflected light over time. The pulse measurement unit 640 calculates the pulse rate from the time change in the intensity of the reflected light. The pulse measurement unit 640 can control the emission and reception of light to the light-emitting / light-receiving unit 621. The pulse measurement unit 640 sends pulse data to the display control unit 450. The display control unit 450 reads the pulse display image data from the image data storage unit 420 according to the computer program in the image data storage unit 420, and sends signals to each drive circuit 510 to 514 to cause the display units 210 to 214 to display the pulse rate.

[0134] The pulse rate display 270 of the display units 210-214 includes a heart mark 271 displayed, for example, in the center of the top display unit 210, and lines 272 extending from the heart mark 271 through the top display unit 210 to each of the side display units 211-214. The heart mark 271 flashes according to the detected pulse rate. The lines 272 are displayed cumulatively, for example, starting from the display unit 214, and progressing in the order of display unit 213, display unit 212, and display unit 211 (see the direction of the arrows in Figure 26).

[0135] [Third display method] Figure 27 is a diagram illustrating the third display mode of the wristwatch 1 according to Embodiment 3. As shown in Figure 27, the third display mode is a different display mode from the second display mode, and is a mode in which the pulse measurement display 285 is displayed on the display units 210 to 214. When measuring the pulse, the user selects, for example, "Other display modes" from the display image selection screen which functions as a display image selection unit 410, and then selects, for example, "Pulse measurement no. 2" from among the multiple options in "Other display modes". This makes it possible to measure the pulse, as described in the second display mode. When the user selects the pulse measurement no. 2 mode, the pulse measurement unit 640 emits light from the light-emitting / light-receiving unit 621 after a predetermined time has elapsed since the user's selection instruction (for example, after 10 seconds), and detects the pulse through the blood vessels in the user's wrist. When the pulse measurement unit 640 sends pulse data to the display control unit 450, the display control unit 450 reads the image data for pulse display from the image data storage unit 420 according to the computer program in the image data storage unit 420, and sends signals to each drive circuit 510 to 514 to cause the display units 210 to 214 to display the pulse. In the third display mode, it is also possible to log the changes in the pulse over time on the side display units 211 to 214.

[0136] The display 285 during pulse measurement differs from the pulse display in the second display mode. This display 285 is performed, for example, in conjunction with music playback and includes a display 286 of information related to the music on the top display unit 210 and a visualizer display 287 of pulse information on the side display units 211-214. This display 287 moves according to the pulse. If the user has set their favorite song in advance, the display control unit 450 can also select and play that song. Song selection can be done from the image data storage unit 420 or a server on the cloud. Note that the display 285 does not necessarily have to be accompanied by music playback. For example, the change in pulse may be displayed on the side display units 211-214 along with the normal time display on the top display unit 210. Alternatively, the display 285 may be performed when the pulse is measured while music is playing. Furthermore, although pulse and heart rate are strictly different, heart rate measurement may be performed instead of pulse measurement. In that case, it is preferable to obtain the heartbeat signal from near the heart, for example. For example, the watch 1 may be equipped with a sensor capable of detecting vibrations during a heartbeat, and the heartbeat information may be sent to the watch 1 by attaching the sensor near the heart.

[0137] If the user wishes to display an electrocardiogram (ECG), the user selects, for example, "Other display modes" from the display image selection screen, which functions as a display image selection unit 410, and then selects, for example, "ECG measurement" from among several options within "Other display modes." This enables ECG measurement. When the user selects the ECG measurement mode, the ECG measurement unit 660 measures the ECG using the light-emitting / receiving unit 621 after a predetermined time has elapsed since the user's selection (for example, 10 seconds later). Similar to heart rate measurement, the ECG measurement unit 660 captures the time-dependent change in reflected light obtained by emitting light from the light-emitting / receiving unit 621 toward the blood vessels and converts this into a waveform. The display control unit 450 receives waveform display data from the ECG measurement unit 660 and reads the ECG display image data from the image data storage unit 420 according to the computer program in the image data storage unit 420. The display control unit 450 then sends signals to each drive circuit 510-514 to cause the display units 210-214 to display the electrocardiogram. For example, the waveform of the electrocardiogram can be displayed over time on at least one of the side display units 211-214 in Figure 27. The electrocardiogram may also be measured electrically by providing electrodes on the underside of the wristwatch or belt and passing them through these electrodes.

[0138] For example, activity information such as "what time the user woke up and went to sleep" and "how many hours they slept" can also be displayed on the display units 210-214 by the display control unit 450 after the pulse measurement unit 640 and light-emitting / receiving unit 621 detect the user's heart rate. This is because it can detect the rapid increase in heart rate upon waking and the rapid decrease in heart rate upon going to sleep. As a variation of the third display mode, instead of displaying "changes in pulse rate over time" on the side display units 211-214, it is also possible to display "changes in sound pressure level over time" as beat information of the music being played.

[0139] [Fourth display mode] Figure 28 is a diagram illustrating the fourth display mode of the wristwatch 1 according to Embodiment 3. As shown in Figure 28, the fourth display mode is a mode in which the user's body temperature display 295 is displayed on the display units 210 to 214. When measuring body temperature, the user selects, for example, "Other display modes" from the display image selection screen, which functions as a display image selection unit 410, and then selects, for example, "Body temperature measurement" from among the multiple options in "Other display modes". This enables body temperature measurement. When the user selects the body temperature measurement mode, the body temperature measurement unit 670 measures the body temperature using the body temperature measurement sensor 622 after a predetermined time has elapsed since the user's selection instruction (for example, after 10 seconds). After the body temperature measurement is complete, the body temperature measurement unit 670 receives the body temperature data from the body temperature measurement sensor 622 and sends the data to the display control unit 450. The display control unit 450 reads out the image data for displaying body temperature from the image data storage unit 420 according to the computer program in the image data storage unit 420, and sends signals to each drive circuit 510 to 514 to cause the display units 210 to 214 to display the body temperature 295.

[0140] In Figure 28, a band-shaped display section 296, extending from the side display section 212 through the top display section 210 to the side display section 214, displays a region 297 indicating high or low body temperature. This region 297 extends from the lower side in the width direction of the side display section 214 to the top display section 210. When the body temperature exceeds normal, this region 297 extends from the top display section 210 towards the side display section 212. In this display configuration, the numerical value indicating body temperature (in this example, "36.5℃") is displayed on the band-shaped display section 296 along with the region 297. However, the numerical value indicating body temperature is not essential. Also, the current time is not displayed on the top display section 210, but it may be displayed.

[0141] [Example of activity information detection and display using an accelerometer] The accelerometer 610, which serves as a detection unit in the wristwatch 1, can also detect information related to the user's activity. For example, information such as the number of steps taken and the distance walked can be detected through the accelerometer 610. The number of steps and distance walked can be displayed on the side display units 211 to 214, with the length changing according to the number of steps and distance.

[0142] As described above, the wristwatch 1 according to Embodiment 3 can display the user's health or fitness information, as well as a wide range of activity-related information including said fitness information, on the display units 210-214 by utilizing information from the acceleration sensor 610, blood pressure measurement unit 630, pulse measurement unit 640, electrocardiogram measurement unit 660, and body temperature measurement unit 670, thus providing a wristwatch with unprecedented new value.

[0143] (Embodiment 4) Next, Embodiment 4 of the present invention will be described. In Embodiment 4, components common to the previously described embodiments are denoted by the same reference numerals, and their descriptions may be omitted.

[0144] Figure 29 is a functional block diagram showing the configuration of the control system for operating the wristwatch 1 according to Embodiment 4. The functional block diagram in Figure 29 mainly shows the functional blocks necessary for displaying information and the sensors necessary for detecting the movement of the wristwatch 1, among the various functions that the wristwatch 1 according to Embodiment 4 has. Hereinafter, the functions specific to Embodiment 4 will be described with reference to Figure 29, and redundant explanations of functions common to the aforementioned embodiments will be omitted.

[0145] The watch body 100 includes, in addition to the various components such as the display image selection unit 410, image data storage unit 420, synchronization signal generation unit 430, time data generation unit 440, and display control unit 450 as described in the embodiments above, a microphone 690 and a GPS (Global Positioning System) 700 as detection units. At least the display control unit 450, microphone 690, and GPS 700 of the watch body 100 perform various processes through the operation of a processing unit such as a CPU and GPU. In this embodiment, the display on the display units 210 to 214 can be selected or changed by voice via the microphone 690. The microphone 690 also includes a calculation unit. The display image selection unit 410 enables the selection of display and switching modes based on voice input. When the display control unit 450 receives voice data via the microphone 690, it recognizes the voice and reads specific image data according to a computer program in the image data storage unit 420. Next, the display control unit 450 causes the display units 210 to 214 to display images using the respective drive circuits 510 to 514.

[0146] By equipping the watch 1 with a GPS 700 as a detection unit, it is possible to display a specific information when the watch 1 enters a specific location range. In addition, in the watch 1 according to Embodiment 4, the user's current location can also be displayed on the display units 210 to 214 via the GPS 700. The GPS 700 also includes a calculation unit. The display image selection unit 410 enables the selection of a mode for detecting the user's location using the GPS 700. When the display control unit 450 receives user location information data via the GPS 700, it reads specific image data (including map data) according to a computer program in the image data storage unit 420. Subsequently, the display control unit 450 uses the drive circuits 510 to 514 to display an image showing the user's location on a map on the display units 210 to 214.

[0147] [First display mode] Figure 30 is a diagram illustrating the first display mode of the wristwatch 1 according to Embodiment 4. As shown in Figure 30, the first display mode shows how multiple images 258 constituting the video frame are stacked from the present (top) to the past (bottom). As time progresses, the top display unit 210 displays the image that is closest to the present among the multiple images 258. The four side display units 211 to 214 display the end faces 260 of the stacked multiple images 258. For example, a total of 1000 images 258 are stored, and the display units 210 to 214 show the most recent 100 images as if they were exposed and stacked on the belt 300. The newest image (No. 1000) 258 is displayed on the top display unit 210. The image 258 at the bottom of the stacked 100 images 258 corresponds to the 901st image counting from the oldest image 258. The oldest images, from 258 to 900, are not displayed on display sections 210-214, and are positioned as if they were embedded below the watch body 100. Additionally, the end faces 260 of image 258 (100 images in total) are displayed on side display sections 211-214.

[0148] In Embodiment 4, when executing the first display mode, the user selects, for example, "Other display modes" from the display image selection screen, which functions as a display image selection unit 410, and then selects, for example, "Video frame" from among the multiple options in "Other display modes". After the user selects the video frame mode, when the user says "Turn over one page", the microphone 690 receives the sound. The display control unit 450 analyzes the sound from the microphone 690 and reads the image data storage unit 420 with the image 258 turned over by one page (the 999th image counting from the oldest image 258: No. 999), sends signals to each drive circuit 510~514, and displays the image on the display units 210~214. The above series of operations by the display control unit 450 are performed according to a computer program stored in the image data storage unit 420. In this way, image 258 No. 999 is displayed on the top display unit 210. The end faces 260 of the 100 images 258 are displayed on the side display sections 211 to 214.

[0149] The display or switching operation based on the sound emitted to the microphone 690 can also be applied when performing one or more display modes in each of the embodiments described above.

[0150] For example, in the first display mode of Embodiment 2, the numbers constituting the current time 252 may be made to appear to dance by giving an instruction such as "dancing" to the microphone 690. The image data storage unit 420 stores image data that causes the numbers constituting the current time 252 to appear to dance based on the reception of the voice command "dancing". The display control unit 450 reads the image data from the image data storage unit 420 according to the computer program in the image data storage unit 420 and sends signals to each drive circuit 510 to 514 to cause the display units 210 to 214 to display the dancing numbers. Similar examples apply to other display modes of Embodiments 2 and 3 described above. As a modification, the same display as described above can also be performed by emitting a voice into another microphone mounted on a smartphone that can communicate with the communication unit (not shown) of the wristwatch 1. In this case, the display control unit 450 or the calculation unit of the microphone 690 reads out the image data in the image data storage unit 420 according to the computer program in the image data storage unit 420 based on the audio data received wirelessly or via wired connection from the smartphone's microphone, and sends signals to each drive circuit 510 to 514 to cause the display units 210 to 214 to display numbers dancing.

[0151] [Second display mode] Figure 31 is a diagram illustrating the second display mode of the wristwatch 1 according to Embodiment 4. As shown in Figure 31, the second display mode can be displayed on the display units 210-214 by the user selecting a GPS function mode from the display image selection unit 410 or by uttering a voice command such as "Activate GPS" through the microphone 690. When the GPS 700 is activated, the display control unit 450 reads map image data from the image data storage unit 420 according to a computer program in the image data storage unit 420. The type of map image and the user's current location data are determined based on radio waves received by the GPS 700 from multiple satellites. When the display control unit 450 receives data from the GPS 700, it sends signals to each drive circuit 510-514 to cause the display units 210-214 to display the map image 298 and the user's current location 299. The top display unit 210 also displays the current time 252, but the current time 252 may be hidden.

[0152] [Examples of activity information detection and display using a microphone or GPS] The microphone 690 and GPS 700, which are detection units equipped in the wristwatch 1, can be used individually or together to detect and display the following activity information. For example, information such as "how many hours a chair was sat in," "how many hours a chair was sat in continuously," and "how many hours a swimmer was swam" can be easily detected using the microphone 690 and GPS 700. When sitting in a chair or starting to swim, the user simply needs to emit voice messages towards the microphone 690 to indicate the start and end of the action. The user's position can be detected by the GPS 700 to determine whether they are sitting in a chair or continuing to swim. In addition, information such as "what was eaten," "how many calories were consumed," "how many hours a movie was watched," "how many hours a TV was watched," "how many hours a book was read," and "how many hours a work was done" can be easily detected by emitting voice messages towards the microphone 690 before and after each action, indicating the type of action and the start and end of the action.

[0153] As described above, the wristwatch 1 according to Embodiment 4 can display a first display mode, a second display mode, and other display modes on the display units 210-214 using information from the microphone 690 and GPS 700, thus providing a wristwatch with unprecedented new value.

[0154] (Other embodiments) In each of the embodiments described above, further modifications are also possible. For example, when the acceleration sensor 610 detects an acceleration that exceeds a second threshold greater than the first threshold, the display units 210 to 214 display the fifth or sixth display mode of Embodiment 2 (see Figures 18 to 20). However, even in the other display modes of Embodiment 2, the display may be changed when the acceleration exceeds a preset second threshold. For example, when the acceleration exceeds the second threshold, the displayed object (such as a number or liquid) may be moved faster than when the acceleration is within the range between the first and second thresholds. Also, one or more thresholds may be set for the sound detected by the microphone 690, and when the decibel value of the sound exceeds a predetermined threshold, the displayed object (such as a number or liquid) may be moved faster.

[0155] In Embodiment 1 described above, the image sensor was provided on a wristwatch or strap, but the present invention is not limited thereto. The image sensor may be provided on the user's eyeglasses or sunglasses, and information regarding the positional relationship between the user's eye and the wristwatch may be detected from the image of the wristwatch captured using the image sensor.

[0156] In the embodiments and their modifications described above, the present invention was explained with reference to a wristwatch 1. However, the present invention is not limited to a wristwatch 1, and can also be a wristwatch-type display device. A wristwatch-type display device has the same or similar form as a wristwatch 1 and refers to a device that does not display the time or a device that displays the time but whose main purpose is to display something other than the time. In the case of a wristwatch-type display device, the configuration can be the same as that of the wristwatch 1 described above, except for the time display. That is, in a wristwatch-type display device, the watch-type display device body (corresponding to the wristwatch body 100) in Figure 2 comprises five organic EL display sheets 210 to 214 as display units formed over the entire area of ​​each of the five surfaces of the six surfaces that make up its surface, excluding the bottom surface that faces the user's arm when in use; a display control unit 450 that controls the display of each of the five display units; and a detection unit that detects at least one piece of information from the position information, posture information, movement information, and user health-related information of the wristwatch-type display device. The display control unit 450 has the function of controlling the display of each of the five display units 210 to 214 based on at least one piece of information detected by the detection unit. The display control unit 450 has the function of controlling the display of each of the five display units 210 to 214 so that the images displayed on each of the five display units 210 to 214 are linked or related. For example, the display control unit 450 can control the display of each of the five display units 210 to 214 so that, from the user's perspective, it appears as if the inside of the wristwatch-type display device body is transparent.

[0157] Thus, the wristwatch-type display device of the present invention makes it possible to display various images in various ways by utilizing not only the top surface of the rectangular parallelepiped wristwatch-type display device body but also the four sides. For this reason, the wristwatch-type display device of the present invention makes it possible to provide a wristwatch-type display device with unprecedented new value.

[0158] Furthermore, the wristwatch or wristwatch-type display device of the present invention may include all or part of the components of the wristwatch 1 according to Embodiments 1 to 4. For example, a modified wristwatch or wristwatch-type display device of the present invention may include all or part of the following: the image sensors 50, 60 and calculation unit 460 of the wristwatch 1 according to Embodiment 1; the acceleration sensor 610 of the wristwatch 1 according to Embodiment 2; the light-emitting / light-receiving unit 621, body temperature measurement sensor 622, blood pressure measurement unit 630, pulse measurement unit 640, electrocardiogram measurement unit 660 and body temperature measurement unit 670 of the wristwatch 1 according to Embodiment 3; and the microphone 690 and GPS 700 of the wristwatch 1 according to Embodiment 5. The display or switching of voice via the microphone of a smartphone is not limited to Embodiment 4 but is also possible in other embodiments.

[0159] Furthermore, while the present invention illustrates a case where a black material is embedded in the gaps formed between the five display sections 210 to 214 (between adjacent organic EL display sheets) to make the gaps less noticeable, since organic EL display sheets are thin, gaps may not be formed to a noticeable extent in the areas adjacent to each organic EL display sheet. In such cases, it is not necessary to embed a black material in the areas adjacent to each organic EL display sheet.

[0160] Furthermore, the present invention illustrates a case where the five display units 210 to 214 of the wristwatch or wristwatch-type display device consist of five organic EL display sheets (see Figure 2(b)). In the above embodiment, an example of a modified organic EL display sheet is shown in which the five display units 210 to 214 consist of one organic EL display sheet, but the invention is not limited thereto. That is, the five display units 210 to 214 may consist of two to four organic EL display sheets. For example, as shown in Figure 32, the five display units 210 to 214 may consist of three organic EL display sheets. In Figure 32, the first side display unit 211, the top display unit 210, and the third side display unit 213 are connected by one organic EL display sheet, while the second side display unit 212 and the fourth side display unit 214 each consist of two separate organic EL display sheets. As a result, the five display units 210-214 consist of three organic EL display sheets.

[0161] It should be noted that the example of the five display units 210-214 consisting of three organic EL display sheets is not limited to this. Although not shown in the diagram, for example, the second side display unit 212, the top display unit 210, and the fourth side display unit 214 may be connected to a single organic EL display sheet, while the first side display unit 212 and the third side display unit 214 may each consist of two separate organic EL display sheets. Thus, the five display units 210-214 consist of three organic EL display sheets.

[0162] Although not shown in the diagram, the five display units 210-214 may also consist of two organic EL display sheets. For example, the first side display units 211-4th side display units 214 may be connected to a single organic EL display sheet, while the top display unit 210 is separated to form a single organic EL display sheet. In this case, the five display units 210-214 consist of two organic EL display sheets.

[0163] Similarly, although not shown in the diagram, the five display units 210-214 may consist of four organic EL display sheets. For example, the first side display unit 211 and the top display unit 210 may consist of one connected organic EL display sheet, while the second side display unit 212, the third side display unit 213, and the fourth side display unit 214 may each consist of three separate organic EL display sheets. In this way, the five display units 210-214 consist of four organic EL display sheets.

[0164] Furthermore, although the wristwatch or wristwatch-type display device of the present invention has been described as having five display units, it does not have to have five display units. That is, the wristwatch or wristwatch-type display device of the present invention may comprise a rectangular parallelepiped wristwatch body 100 or wristwatch-type display device body, at least two display units formed over the entire area of ​​each of the six surfaces constituting the surface of the wristwatch body 100 or wristwatch-type display device body, namely the "upper surface opposite to the lower surface that faces the user's arm when in use" and "at least one of the four side surfaces", and a display control unit that controls the display of each of the at least two display units. In other words, in each of the above embodiments, the at least two display units are five display units formed over the entire area of ​​each of the five surfaces consisting of the upper surface and the four side surfaces, but the wristwatch or wristwatch-type display device of the present invention may have at least two display units instead of five.

[0165] Figure 33 shows an example of a case where the display unit 20 consists of at least two display units. In Figure 33, the display unit 200 of a wristwatch or wristwatch-type display device having 2 to 4 display units is shown in an unfolded state as at least two display units. In Figure 33, Figures 33(a) and 33(b) show the case with 2 display units, Figures 33(c) to 33(f) show the case with 3 display units, and Figures 33(g) to 33(i) show the case with 4 display units. As shown in each figure of Figure 33, in a wristwatch or wristwatch-type display device having 2 to 4 display units, there are surfaces that do not have display units made of organic EL display sheets, but protective members may also be applied and cured on the surfaces that do not have display units made of organic EL display sheets.

[0166] Furthermore, as shown in each of the figures in Figure 33, even when there are 2 to 4 display units, each display unit may consist of multiple organic EL display sheets or of one organic EL display sheet. Specifically, Figures 33(a) and 33(h) show cases where each display unit consists of two organic EL display sheets, Figures 33(c) and 33(e) show cases where each display unit consists of three organic EL display sheets, and Figure 33(g) shows cases where each display unit consists of four organic EL display sheets.

Conversely, although the top display section 210 is rectangular in the embodiments described above, it may also be square.

[0168] Furthermore, while the present invention illustrates a case where the display unit 200 (five display units 210-214) of the wristwatch or wristwatch-type display device is made of an organic EL display sheet, it may also be made of a micro LED (Light Emitting Diode) display sheet.

[0169] Furthermore, the wristwatch or wristwatch-type display device of the present invention is not limited to the display modes described in the above embodiments, but can also display in the display modes shown in Figures 34 and 35 (display modes in which the display switches by a swipe operation).

[0170] Figures 34 and 35 are diagrams illustrating a display mode in which the display switches by a swipe gesture. In the display mode in which the display switches by a swipe gesture, as shown in the upper diagram of Figure 34, the initial state is that the first image G1 is displayed on the four display units: the top display unit 210, the first side display unit 211, the second side display unit 212, and the third side display unit 213, and the second image G2 is displayed on the remaining fourth side display unit 214. Subsequently, as shown in the lower diagram of Figure 34, by swiping any part P of the boundary between the first image G1 and the second image G2 with a finger, the boundary between the first image G1 and the second image G2, and the boundary between the second image G2 and a third image G3 (not shown) are pulled and moved. Subsequently, when any part P is swiped further with a finger and the swiping motion is ended, the display mode is such that the boundary between the first image G1 and the second image G2, and the boundary between the second image G2 and the third image G3, appear as if they are snapped to something and stop, as shown in Figure 35.

[0171] Examples of displays that can be switched by a swipe include switching between analog and digital displays, switching between clock and calendar displays, and unlocking the device, but various other display switching options are also possible. In the wristwatch 1 according to this embodiment, the display control unit 450 controls the display of each of the five display units 210 to 214 so that the above-described display modes are possible.

[0172] Furthermore, when realizing the 20th display mode, a touch panel is used, in which a touch pad is provided on the surface of each of the five organic EL display sheets, as the five display units 210 to 214. The touch pad may be provided on the surface of the black member 280 or the protective member 290. [Explanation of Symbols]
