DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0009] Hereinafter, an embodiment of an electronic device according to the present invention will be described with reference to the drawings. In the following description, the electronic device will be described as an electronic musical instrument, but the present invention is not limited to electronic devices that are electronic musical instruments, and can be applied to any electronic device that has a display unit and an input interface, which will be described later. Furthermore, the scope of the invention is not limited to the illustrated examples.

[0010] [Configuration of electronic musical instrument 100] Fig. 1 is a block diagram showing the functional configuration of an electronic musical instrument 100 according to the present invention, Fig. 2 is a diagram showing an example of the external configuration of the electronic musical instrument 100. As shown in Figures 1 and 2, the electronic musical instrument 100 is configured to include at least one processor such as a CPU (Central Processing Unit) 11, a ROM (Read Only Memory) 12, a RAM (Random Access Memory) 13, a keyboard 14, an operation unit 15, a display unit 16, a sound system 17, and a communication unit 18, and each unit is connected by a bus 19.

[0011] The CPU 11 reads out the programs and data stored in the ROM 12 and executes various processes using the RAM 13 as a work area, thereby centrally controlling each section of the electronic musical instrument 100. For example, the CPU 11 causes the sound system 17 to output the sound of a musical instrument such as a piano according to the pitch of a pressed key on the keyboard 14, and causes the sound system 17 to output a piece of music selected by the operation section 15. The CPU 11 also causes the sound system 17 to play music based on audio data input from an external device via the communication section 18. The CPU 11 also functions as a control section of the present invention by executing a light emission control process, which will be described later.

[0012] The ROM 12 stores programs and various data. The RAM 13 provides a working memory space for the CPU 11 and temporarily stores data.

[0013] The keyboard 14 is configured to include a plurality of keys (operators) and outputs information about pressed / released keys to the CPU 11.

[0014] The operation unit 15 has various switches and operation keys, and outputs to the CPU 11 operation signals in response to the operation of the various switches and operation keys by the user.

[0015] As shown in FIG. 2, the operation unit 15 includes an input ring 151, which is an annular input interface. The input ring 151 includes a detection unit (sensor) that detects the contact position between the operating object and the detection surface, which is one continuous area in a circular ring shape, by a change in capacitance, and a plurality of light-emitting units (LEDs (Light Emitting Diodes)) that are arranged in a circular ring shape at positions corresponding to the detection unit and light the detection surface. The input ring 151 detects the contact position of the operating object on the detection surface of the input ring 151, outputs the contact position to the CPU 11, and causes the light-emitting unit to light up according to the control of the CPU 11. Note that the detection by the detection unit does not necessarily require the operating object to be in "contact" with the detection surface, and may detect a change in capacitance when the operating object is in "proximity (non-contact state)" to the detection surface. In other words, it is sufficient to detect the contact or proximity of the operating object to the detection surface when the capacitance has changed by more than a threshold value. In addition, the detection unit may not be a sensor that detects a change in capacitance, and may be an optical sensor or a heat sensor, as long as it can detect the contact or proximity of the operating object.

[0016] In this embodiment, the operation object is a finger, but the operation object is not limited to this, and may be other objects such as a touch pen, etc. In addition, in this embodiment, the input ring 151 is annular, but the input ring 151 is not limited to annular, and may be, for example, elliptical, square, rectangular, etc.

[0017] The display unit 16 is configured with an LCD (Liquid Crystal Display) or the like, and performs display according to instructions of a display signal input from the CPU 11.

[0018] The sound system 17 includes a sound source unit 171 , an audio circuit 172 , and a speaker 173 . The sound source unit 171 , in accordance with a control instruction from the CPU 11 , reads out waveform data pre-stored in the ROM 12 or generates waveform data and outputs it to the audio circuit 172 . The audio circuit 172 performs D / A conversion and amplifies the waveform data output from the sound source unit 171 or the waveform data (audio data) input from the communication unit 18, and the speaker 173 outputs the amplified analog sound.

[0019] The communication unit 18 transmits and receives data to and from external devices such as an external terminal connected via a communication interface such as the Internet, Bluetooth (registered trademark), or a USB (Universal Serial Bus) cable, or an external recording medium such as a USB memory.

[0020] [Operation of electronic musical instrument 100] Next, the operation of the electronic musical instrument 100 will be described. When options are displayed on the display unit 16, the CPU 11 divides the circumference of the input ring 151 into a plurality of regions according to the number of options, and when an area of ​​the input ring 151 corresponding to one of the options is tapped, it determines that the option corresponding to the tapped area has been selected.

[0021] 3 is displayed on the display unit 16, the CPU 11 divides the circumference (on the detection surface) of the input ring 151 into four regions, top, bottom, left and right (for example, into four regions, top, bottom, left and right, with equal arc lengths), and sets the right region (right region) 151a as the region for selecting "YES" and the left region (left region) 151b as the region for selecting "NO." If the right region 151a is tapped, it is determined that YES has been selected, and if the left region 151b is tapped, it is determined that NO has been selected.

[0022] However, if there is no means of informing the user that they can select YES by tapping right area 151a of input ring 151 and that they can select NO by tapping left area 151b, the user will not know how to make the selection, which would be inconvenient.

[0023] 4, the CPU 11 enables the user to recognize how to select an option. The light emission control process is executed by the CPU 11 in cooperation with a program stored in the ROM 12.

[0024] In the light emission control process, first, the CPU 11 turns off (extinguishes) all light emitting parts of the input ring 151, and then lights up (illuminates) the right area 151a and the left area 151b (step S1). 3 is a diagram showing a schematic view of the display on the display unit 16 and the input ring 151 in step S1. Note that in the display on the input ring 151 in FIGS. 3, 5 to 8, the darker the color, the higher the luminescence intensity (unit: nit, etc.). White indicates no light emission.

[0025] Next, the CPU 11 causes the word "YES" on the confirmation screen 161 of the display unit 16 to blink (step S2). In this embodiment, "blinking" refers to repeating lighting on and off several times (for example, 2-3 times) per second. Furthermore, CPU 11 causes the light emitting portion of right region 151a of input ring 151 to blink in synchronization with the timing of the blinking of the character "YES" (step S3). Note that "synchronization" in this embodiment refers to the fact that the display of at least a portion of the content (characters, symbols, etc.) on display unit 16 and at least a portion of the light emitting portion of input ring 151 are linked to each other and either turn on (light emission), turn off (extinguishing), or blink. Also, the "synchronization" between the display of display unit 16 and the light emission of input ring 151 does not have to be at exactly the same timing, and there may be a delay of about several ms.

[0026] 5 is a diagram showing a schematic display of the display unit 16 and the input ring 151 in steps S2 to S3. In FIG. 5, the solid lines around the character "YES" displayed on the display unit 16 and extending to the right side of the input ring 151 show that the character "YES" and the light-emitting part in the right area (right area 151a) of the input ring 151 are flashing in synchronization with each other (the same applies to "NO" in FIG. 6). As shown in FIG. 5, by flashing the character "YES" in the confirmation screen 161 and the light-emitting part in the right area 151a of the input ring 151 in synchronization with each other, the user can recognize that the option for "YES" in the confirmation screen 161 corresponds to the right area 151a of the input ring 151 and that "YES" can be selected by tapping the right area 151a.

[0027] Next, the CPU 11 stops the blinking of the character "YES" on the confirmation screen 161 of the display unit 16 and the light-emitting part of the right region 151a of the input ring 151, and causes the character "NO" on the confirmation screen 161 of the display unit 16 to blink (step S4). Furthermore, the CPU 11 causes the light emitting portion of the left region 151b of the input ring 151 to blink in synchronization with the timing of the blinking of the character "NO" (step S5).

[0028] Fig. 6 is a diagram showing a schematic view of the display on the display unit 16 and the input ring 151 in steps S4 and S5. As shown in Fig. 6, by flashing the character "NO" in the confirmation screen 161 and the light-emitting part in the left region 151b of the input ring 151 in synchronization with each other, the user can recognize that the option for "NO" in the confirmation screen 161 corresponds to the left region 151b of the input ring 151 and that "NO" can be selected by tapping the left region 151b.

[0029] Next, the CPU 11 stops the blinking of the character "NO" on the confirmation screen 161 of the display unit 16 and the light emitting part of the left region 151b of the input ring 151 (step S6). As a result, the right region 151a and the left region 151b of the input ring 151 are turned on (emitted light).

[0030] Next, the CPU 11 waits for a tap operation to be performed on either the right area 151a or the left area 151b of the input ring 151 (step S7). When it is determined that either the right region 151a or the left region 151b of the input ring 151 has been tapped (step S7; YES), the CPU 11 determines whether YES or NO has been selected on the display unit 16 depending on the region that has been tapped (step S8), transitions the display unit 16 to the next screen depending on the selection, and executes processing depending on the selection (step S9), and ends the light emission control processing. Even if an area other than the right area 151a or the left area 151b of the input ring 151 is tapped, the CPU 11 does not change the content displayed on the display unit 16 and invalidates the operation.

[0031] In this way, in the light emission control process, first, while the confirmation screen 161 is being displayed, the CPU 11 lights up (illuminates) a light emitting portion in the right region 151a of the input ring 151 corresponding to the option "YES" on the confirmation screen 161 and a light emitting portion in the left region 151b corresponding to the option "NO". Next, the CPU 11 blinks the word "YES" on the confirmation screen 161, and blinks the light emitting portion in the right region 151a of the input ring 151 in synchronization with the timing of the blinking of the word "YES". Next, the CPU 11 blinks the word "NO" on the confirmation screen 161, and blinks the light emitting portion in the left region 151b of the input ring 151 in synchronization with the timing of the blinking of the word "NO". Therefore, since the user can be informed of how to select each of the options "YES" and "NO" on the confirmation screen 161, the convenience of the user's operations regarding the screen display can be improved.

[0032] As described above, electronic musical instrument 100 includes display unit 16, and input ring 151 having a detection unit that detects contact between an operating object and a circular detection surface, and a plurality of light-emitting elements that are arranged in a circular shape at positions corresponding to the detection units and illuminate the detection surface, and CPU 11 controls so as to synchronize (link) the display of at least a portion of the content on display unit 16 with the illumination of at least a portion of the plurality of light-emitting elements of input ring 151. Therefore, for example, the user can be notified by lighting up the operating portion of the input ring 151 corresponding to the display on the display unit 16 in synchronization with the display on the display unit 16, thereby improving the convenience of user operations regarding the screen display.

[0033] Also, for example, when the CPU 11 displays at least two options on the display unit 16, it sets selection areas on the detection surface of the input ring 151 corresponding to each of the options displayed on the display unit 16, and causes the light-emitting parts among the multiple light-emitting parts corresponding to each selection area to emit light. Therefore, the user can easily recognize which area of ​​the input ring 151 can be operated to select an option on the screen.

[0034] Furthermore, for example, the CPU 11 can synchronize and light (illuminate) or blink each of the options displayed on the display unit 16 with the light-emitting units corresponding to the selection areas of the input ring 151 corresponding to each of the options, thereby enabling the user to more easily and intuitively recognize which area of ​​the input ring 151 needs to be operated to select an option on the screen.

[0035] Also, for example, the CPU 11 performs control so as not to change the content displayed on the display unit 16 even if the operating object is brought into contact with or close to an area of ​​the detection surface of the input ring 151 that corresponds to a non-emitting light-emitting part. Therefore, it is possible to invalidate the operation of the part that is not synchronized with the display.

[0036] The above-described embodiment and modified examples are merely preferred examples of the electronic device, electronic musical instrument, control method, and program according to the present invention, and the present invention is not limited to these.

[0037] For example, in the above embodiment, the case where the options displayed on the display unit 16 are two options, "YES" and "NO", is described as an example, but the number of options is not limited to two. For example, when displaying four options on the display unit 16, the CPU 11 may divide the detection surface (circumference) of the input ring 151 into four areas (for example, four areas with equal arc lengths) on the top, bottom, left, and right, set selection areas corresponding to each of the four options, and sequentially light up (emit light) or blink while synchronizing each of the four options with the selection areas corresponding to each of the four. This allows the user to easily recognize which area of ​​the input ring 151 should be operated to select each of the four options.

[0038] 7, for example, by sliding the input ring 151, it is possible to switch, for example, underlined characters ("L" in FIG. 7) to alphabetical order, but some users are unaware of this function. Therefore, when accepting a sliding operation of the detection surface of the input ring 151 by the operating object (for example, when the character switching screen 162 is displayed), the CPU 11 may display a display showing the rotation of a circular figure on the screen displayed on the display unit 16, and may sequentially cause some of the multiple light-emitting parts of the input ring 151 to emit light in synchronization with the rotation of the circular figure displayed on the display unit 16. 7, for example, a diagram (called a ring diagram) R1 representing the input ring 151 is displayed on the screen displayed on the display unit 16, and the ring diagram R1 is illuminated or turned off while being moved sequentially around its circumference to display the rotation of the ring diagram R1, and in synchronization with the illumination or turning off of the ring diagram R1 around its circumference, the illumination parts of the input ring 151 at positions corresponding to the illuminated or turned off positions of the ring diagram R1 are illuminated (others are turned off). This enables the user to intuitively recognize that the input ring 151 should be slid. In order to make it easier for the user to notice that the input ring 151 is being slid around its circumference, the display unit 16 may display a diagram showing a rotating arc-shaped arrow as shown in FIG. 8, instead of the ring diagram R1.

[0039] 5 and 6 of the above embodiment, a case where one character is kept on while the other character is blinking on the display unit 16 has been described as an example, but the display method is not limited to this. For example, the display unit 16 may be controlled so that one character is kept off while the other character is blinking, and the light-emitting unit of the input ring 151 may be controlled so that one area is turned off and the other area is blinked in synchronization with this. The blinking of the display unit 16 and the input ring 151 includes not only a case where lighting at maximum light emission intensity and complete extinction (zero light emission intensity) are repeated, but also a case where lighting at maximum light emission intensity and lighting at a light emission intensity weaker than the maximum light emission intensity are repeated.

[0040] In the above embodiment, an example is disclosed in which a semiconductor memory such as a ROM is used as a computer-readable medium for the program according to the present invention, but the present invention is not limited to this example. As other computer-readable media, a portable recording medium such as an HDD, an SSD, or a CD-ROM can be applied. In addition, a carrier wave can be applied as a medium for providing data of the program according to the present invention via a communication line.

[0041] In addition, the detailed configurations and operations of the electronic devices and electronic musical instruments may be modified as appropriate without departing from the spirit and scope of the invention.
