Abstract
Description
[Technical Field]
[0001] The present application relates to the technical fields of control devices, control methods, and control programs. More specifically, the present application relates to the technical fields of control devices and control methods for controlling the rotation or movement of a display unit such as a liquid crystal display, and programs for such control devices. [Background technology]
[0002] In recent years, in-vehicle devices equipped with a display unit such as a liquid crystal display have become widespread. In such in-vehicle devices, for example, navigation processing accompanied by map display on the display unit, playback processing of content designated by a user (e.g., a passenger in the vehicle) using the display unit, etc. In this case, in consideration of the above-mentioned uses, it is preferable that the display unit be large.
[0003] On the other hand, in order to address the above points, various measures are required to enlarge the display unit, since the size (area) of the vehicle cabin is limited and there is also a need to ensure the driver's field of vision while driving. An example of a conventional technology that takes such measures into consideration is the technology described in Patent Document 1 below.
[0004] This patent document 1 discloses a configuration in which a large rectangular display protrudes into the vehicle cabin during use, and the display is controlled to be used in landscape or portrait orientation (rotating the display itself) depending on the content displayed on the display. Examples of the content displayed include maps or operation icons. Regarding the control of the rotation, the patent document also discloses a configuration in which the top edge of the display when used in landscape orientation is approximately aligned with the top edge when used in portrait orientation, so that the driver's field of view is not obstructed even when the display is rotated. Furthermore, the patent document also discloses a configuration in which the rotation control is performed when a so-called proximity sensor detects the approach of the driver's or passenger's hand, and the rotation is coordinated with the sliding movement of the display itself.

[0005] [Patent Document 1] Japanese Patent Application Laid-Open No. 2013-121768 Summary of the Invention [Problem to be solved by the invention]
[0006] Here, the use of a large display such as that disclosed in Patent Document 1 is advantageous in terms of the ease of viewing the displayed content and the amount of information that can be displayed at one time. However, when using the display in front of the console (inside the vehicle) where operation buttons and the like are originally located, there is a problem that the operation buttons and the like may be hidden behind the display due to its size, making them inoperable. In this case, it is necessary to move the display, for example, to make the operation buttons and the like operable.
[0007] Therefore, the present application has been made in consideration of the above problems and demands, and one example of its objective is to provide a control device and control method, as well as a program for the control device, that can easily and smoothly move the display itself when a large display is used in front of the console unit. [Means for solving the problem]
[0008] In order to solve the above problem, the invention described in claim 1 comprises a detection unit that detects a pressure force due to contact with a display unit supported by a support unit, and a control unit that controls the rotation or movement of the display unit in either a first direction relative to the support unit or a second direction different from the first direction based on the detected pressure force.
[0009] In order to solve the above problem, the invention described in claim 11 is a control method executed in a control device equipped with a detection unit that detects a pressure force due to contact with a display unit supported by a support unit, and a control unit, and includes a control step in which the control unit controls the rotation or movement of the display unit in either a first direction relative to the support unit or a second direction different from the first direction based on the detected pressure force.
[0010] In order to solve the above problem, the invention described in claim 12 causes a computer included in a control device having a detection unit that detects a pressure force due to contact with a display unit supported by a support unit to function as a control unit that controls the rotation or movement of the display unit in either a first direction relative to the support unit or a second direction different from the first direction based on the detected pressure force.

[0012] Next, an embodiment of the present invention will be described with reference to Fig. 1. Fig. 1 is a block diagram showing a schematic configuration of a control device according to the embodiment.
[0013] As shown in FIG. 1, the control device S according to the embodiment is configured to include a detection unit 1 and a control unit 3.
[0014] In this configuration, the detection unit 1 detects a pressure applied by contact to the display unit D supported by the support unit.
[0015] As a result, the control unit 3 controls the rotation or movement of the display unit D in either a first direction relative to the support unit or a second direction different from the first direction, based on the pressure detected by the detection unit 1.
[0016] As described above, according to the control device S of the embodiment, the rotation or movement of the display unit D in either the first direction or the second direction relative to the support part is controlled based on the pressure caused by contact with the display unit D, so that the display unit D can be moved freely with a simple operation. [Example]
[0017] Next, specific examples corresponding to the above-described embodiments will be described with reference to Figures 2 to 10. The examples described below are examples in which the embodiments are applied to drive control of the position of a display unit provided in an in-vehicle navigation device and configured with a liquid crystal display or the like. In this case, the embodiments are not limited to the above-described navigation device, and can also be applied to, for example, an in-vehicle AV (Audio Visual) device, etc., as long as the device has the above-described display unit.
[0018] FIG. 2 is a block diagram showing the general configuration of a navigation device according to an embodiment, FIG. 3 is a perspective view of a portion of the configuration of the navigation device as viewed from the upper left front, and FIG. 4 is a six-view diagram showing the appearance of a display unit according to an embodiment. FIG. 5 is a perspective view of the rear of the display unit according to the embodiment as viewed from the upper left rear, FIG. 6 is a front schematic view showing an installation example of a navigation device according to an embodiment, and FIG. 7 is a flowchart showing rotation / movement control of the display unit according to an embodiment. FIGS. 8 and 9 are diagrams illustrating examples of rotation or movement of the display unit according to an embodiment, and FIG. 10 is a flowchart showing processing when the display unit according to an embodiment is fixed. In FIG. 2, the same component numbers as those of the control device S according to the embodiment shown in FIG. 1 are used for components of the embodiment that correspond to the components of the control device S.
[0019] As shown in FIG. 2(a), the navigation device NV according to the embodiment includes a control unit 3 including a CPU, a RAM (Random Access Memory), a ROM (Read Only Memory), etc.; an interface 10; a storage unit 11 including a HDD (Hard Disc Drive) or an SSD (Solid State Drive), etc.; an operation unit 12 including operation buttons or a remote control operated by a user; a sensor unit 13 including a GPS (Global Positioning System) or a standalone position sensor, etc.; a display unit D; a drive unit 15 that drives and controls the spatial (three-dimensional) movement and rotation of the display unit D; and an optical disc drive DK that reads and writes information from an optical disc (not shown) inserted therein. In this case, the user is, for example, a driver or a passenger of a vehicle equipped with the navigation device NV. The display unit D includes a display surface F, a touch panel 14 provided on the front surface thereof, and a touch sensor group TS (described later). The display surface F of the display unit D is, for example, the display surface of a liquid crystal display that constitutes the display unit D. On the other hand, the drive unit 15 is composed of a drive section 15a, a rotation motor 15b, a vertical slide motor 15c, a horizontal slide motor 15d, and a front-rear slide motor 15e. In this case, each of the touch sensors included in the touch sensor group TS and the touch panel 14, which will be described later, corresponds to an example of the detection section 1 according to the embodiment.
[0020] In the above configuration, the interface 10 acquires, for example, traffic congestion information, weather information, etc. via an external network such as the Internet, and outputs them to the control unit 3. The recording unit 11 non-volatilely records, for example, map data, etc., used for guidance processing as the navigation device NV, and outputs them to the control unit 3 as needed. The sensor unit 13 outputs the current position of the vehicle in which the navigation device NV is installed, detected by the position sensor, to the control unit 3, and also outputs the results of detection of the vehicle's speed, mileage, direction of travel, etc., to the control unit 3. When the user performs an instruction operation on the navigation device NV through the operation unit 12, the operation unit 12 generates an operation signal corresponding to the instruction operation and outputs it to the control unit 3. The control unit 3 then uses the traffic congestion information, etc., from the interface 10, the detection results of the sensor unit 13, and the map data, etc., recorded in the recording unit 11, to perform guidance processing required for the navigation device NV, as well as control the rotation and movement of the display unit D according to the embodiment, based on the operation signal from the operation unit 12. At this time, the above guidance process may be performed using map data, location data, etc. recorded on the optical disk (not shown) loaded in the optical disk drive DK. Furthermore, the map, etc. required for the guidance process are displayed on the display surface F of the display unit D under the control of the control unit 3.
[0021] In addition to the above configuration, the recording unit 11 has pre-recorded therein pinch contact pattern data and grip contact pattern data indicating preset pinch contact patterns and grip contact patterns, respectively, for determining whether or not a user has performed a "pinch operation" and a "grasp operation" according to the embodiment, which will be described later. Furthermore, the recording unit 11 also has pre-recorded therein first threshold data and second threshold data indicating first threshold values and second threshold values, respectively, which correspond to the pressure applied when a touch by the user to only one location on the display unit D is detected. In the following description, "touch" refers to contact with a touch sensor or the like by the user's finger or hand.
[0022] In this case, the pinch contact pattern is a contact pattern on the display unit D by the user's fingers or the like, which is the contact at one location on the front surface of the display unit D and one location on the back surface of the display unit D, and is a contact pattern that is preset as a contact corresponding to a pinch operation according to the embodiment in which the user pinches the display unit D. The pinch contact pattern is, for example, a contact pattern in which the contact by the user's finger (for example, the thumb) is detected at one location on the front surface of the display unit D, and the contact by the user's two fingers (for example, the index finger and middle finger) is detected at the back surface of the display unit D, which is located near the back side of the location on the front surface where the contact was detected.
[0023] In contrast, the grasping contact pattern is a contact pattern on the display unit D by the user's fingers or the like, which is the contact at two locations on the left and right of the front surface of the display unit D and two locations on the left and right of the back surface, and is a contact pattern that is preset as a contact corresponding to a grasping operation according to an embodiment in which the user grasps (i.e., holds) the display unit D. More specifically, the grasping contact pattern is a contact pattern in which, for example, contact by the user's fingers (e.g., both thumbs) is detected at one location on each side of the front surface of the display unit D, and contact by two or more fingers (e.g., the index finger, middle finger, and ring finger) of the user is detected at two locations on each side of the back surface of the display unit D that are located near the back side of the respective locations on the front surface where the contacts were detected. In this case, two contacts are detected on the front surface of the display unit D, and a total of six contacts are detected on the back surface.
[0024] On the other hand, the first threshold is a pressure threshold used to determine whether to rotate or move the display unit D in a first direction corresponding to the direction of the pressure caused by the contact when a user's contact is detected only at one location on the front or side of the display unit D, unlike the contact caused by the pinch contact pattern or the grip contact pattern. The second threshold is a threshold used to determine whether to rotate or move the display unit D in a second direction corresponding to the opposite direction to the direction of the pressure caused by the contact when a user's contact is detected in a manner similar to the first threshold. In the embodiment, the first threshold is set to a value greater than the second threshold (i.e., first threshold > second threshold). That is, in the navigation device NV according to the embodiment, when a user's contact is detected only at one location on the front or side of the display unit D and the pressure caused by the contact is equal to or greater than the first threshold, the control unit 3 rotates or moves the display unit D in the first direction. On the other hand, when the pressure is equal to or less than the second threshold, the control unit 3 rotates or moves the display unit D in the second direction. If the pressure is greater than the second threshold value and less than the first threshold value, even if the user makes the above-mentioned contact, the control unit 3 will not rotate or move the display unit D. In this case, the range of pressure less than the first threshold value and greater than the second threshold value is treated as a so-called dead zone, and the existence of this dead zone makes it possible to prevent the display unit D from being rotated or moved against the user's will due to the user's erroneous (i.e., unintentional) contact with only one point on the display unit D.
[0025] The navigation device NV may have a function to play music data or the like recorded on, for example, the optical disk (not shown) or the recording unit 11. In this case, the control unit 3 reads out and plays music data corresponding to music designated on, for example, the operation unit 12 from the optical disk or the recording unit 11, thereby driving a speaker (not shown) to emit music corresponding to the music data into the vehicle. At this time, the control unit 3 may be configured to emit the music while displaying an image or the like corresponding to the music on the display surface F.
[0026] On the other hand, the display unit D having the display surface F according to the embodiment has a shape in which the thin display unit D protrudes from the console of the vehicle in which the navigation device NV is mounted via a connecting arm (not shown in FIG. 2) toward the interior of the vehicle. The drive unit 15 controls the rotation of the entire display unit D including the display and controls the position of the display unit D in the space in front of the console. More specifically, the rotation motor 15b constituting the drive unit 15 rotates the entire display unit D within the space including the display surface F. The up-down slide motor 15c constituting the drive unit 15 slides the entire display unit D up and down as viewed from the user within the space including the display surface F (see the up-down arrows in FIG. 3). The left-right slide motor 15d constituting the drive unit 15 slides the entire display unit D left and right as viewed from the user within the space including the display surface F (see the left-right arrows in FIG. 3). The forward-backward slide motor 15e constituting the drive unit 15 slides the entire display unit D forward and backward within the space including the display surface F (see the forward-backward arrows in FIG. 3). Under the control of the control unit 3, the drive unit 15a drives the rotation motor 15b, the up-down slide motor 15c, the left-right slide motor 15d, and the front-rear slide motor 15e.
[0027] Next, a schematic configuration of the display unit D according to the embodiment will be described with reference to FIG. 2(b).
[0028] As shown in Figure 2(b), the display unit D of the embodiment is configured to include the display having the display surface F with the touch panel 14 on its front surface, the touch sensor group TS configured to be able to detect contact with the surface of the display unit D, a camera 16 provided on the back surface of the display unit D, a fixed unit 17, a fixed control unit 18, and a display control unit 19.
[0029] In this configuration, the touch sensor group TS is composed of a plurality of touch sensors provided on the surface of the display unit D (more specifically, the peripheral portion of the front surface of the display unit D other than the display surface F, the top, bottom, left, and right side portions of the display unit D, and the back surface of the display unit D). Each of these touch sensors detects whether or not the user's finger or hand is in contact with the touch sensor, and the pressure applied when such contact occurs, and generates contact information including pressure information indicating the value of the detected pressure, and outputs this information to the control unit 3. In addition, each touch sensor detects changes in the detected pressure, generates change information indicating the change, and outputs this information to the control unit 3. The change in pressure in this case includes a change in the position where the pressure is detected in the contact area of the touch sensor, and a change in the magnitude of the pressure itself at the same contact position. The change in the position where the pressure is detected occurs when the finger or hand moves while maintaining contact with the touch sensor (in other words, by tracing the touch sensor).
[0030] On the other hand, the fixing unit 17 is a fixing unit that physically (mechanically) fixes the display unit D to the connecting arm, and under the control of the fixing control unit 18, physically (mechanically) fixes the display unit D to the connecting arm and makes the display unit D detachable from the connecting arm to which it is fixed. Once detached from the connecting arm, the display unit D is ready to be carried by the user. Fixing of the display unit D to the connecting arm by the fixing unit 17 and transitioning to a state where it can be detached from the connecting arm will be described in detail later.
[0031] The other camera 16 has an imaging range that faces the rear surface of the display unit D (in other words, a range in the direction of a perpendicular line erected on the rear surface), and outputs image information obtained by imaging the imaging range to the display control unit 19. This camera 16 is configured with, for example, a CCD (Charge Coupled Device) or CMOS (Complementary Metal Oxide Semiconductor) imaging element. Then, the display control unit 19 displays an image corresponding to the image information output from the camera 16 on the display surface F based on a user's operation on each touch sensor included in the touch sensor group TS or on the touch panel 14, which will be described later. The display of the image by this display control unit 19 will also be described in detail later.
[0032] Next, the drive unit 15 according to the embodiment and the display unit D whose spatial position and rotation are driven and controlled by the drive unit 15 will be described in more detail with reference to FIGS.
[0033] First, as shown in Fig. 3, in the drive unit 15 according to the embodiment, the display unit D according to the embodiment is supported via a connecting arm 20 on a housing CK that houses the drive unit 15a, the rotary motor 15b, the up-down slide motor 15c, the left-right slide motor 15d, and the front-rear slide motor 15e, etc. In this case, at least one of the height and width of the display unit D may be longer than at least one of the height and width of the drive unit 15. In the case shown in Fig. 3, the optical disk drive DK is also housed below in the housing CK. This housing CK is an example of a "support unit" according to the present application.
[0034] The display unit D has the display surface F with the touch panel 14 provided on its front surface, and further has a touch sensor group TS including touch sensors 1a and the like, which will be described later with reference to FIG. 4, provided on its surface. In the example shown in FIG. 3, the "front surface" refers to the surface from which the display unit D is viewed from the drive unit 15. Furthermore, in FIG. 3, the touch sensor group TS is not shown to simplify the explanation. In the example shown in FIG. 3, the display unit D is in a landscape (horizontal) usage state, but it can also be in a portrait (vertical) usage state by rotating the display unit D about the central axis of the connecting arm 20. Then, the map and other information are displayed on the screen of the display unit D in an easily visible manner depending on whether the display unit D is in a landscape or portrait usage state.
[0035] Furthermore, the touch panel 14 provided on the front surface of the display surface F has a function of transmitting the display on the display surface F and a function of position input. The position input function in this case is realized by, for example, a capacitance type or a resistive film type element. In addition to these, the touch panel 14 detects the presence or absence of contact with the display surface F, similar to the touch sensor group TS. In this regard, if the touch panel 14 is configured with a resistive film type element, it is possible to detect the presence or absence of the contact and the pressure at that time. In contrast, if the touch panel 14 is configured with a capacitance type element, it is also possible to detect whether the finger or hand has approached the touch panel 14 (without contact) in addition to the contact. In the case of proximity, the pressure is not detected.
[0036] Next, as shown in Figure 3, the housing CK contains a vertical slide stage 21 that supports a connecting arm 20 fixed to the center of the back of the display unit D and incorporates a rotary motor 15b and a vertical slide motor 15c shown in Figure 2(a), a left-right slide stage 23 and a left-right slide stage 24 that sandwich an upper and lower guide 22 that passes through a guide hole that passes through the vertical slide stage 21 and incorporates a left-right slide motor 15d shown in Figure 2(a), a front-rear slide stage 25 that incorporates a front-rear slide motor 15e shown in Figure 2(a) and has a guide groove 25a, front-rear guides 26 and 27 that have guide grooves 27a formed on their respective opposing inner surfaces and are fixed to the housing CK, and an optical disk drive DK.
[0037] In this configuration, the connecting arm 20 has, for example, a cylindrical shape. A part of the connecting arm 20 passes through a circular hole HL provided in the front surface of the housing CK and is exposed toward the front of the drive unit 15. The end of the exposed part of the connecting arm 20 is fixed approximately perpendicular to the display unit D near the center of the back surface of the display unit D.
[0038] Meanwhile, the vertical sliding stage 21 supports the connecting arm 20 so that the connecting arm 20 (in other words, the display unit D) can rotate around its central axis as a rotation axis. The rotary motor 15b built into the vertical sliding stage 21 rotates the connecting arm 20. As a result, the entire display unit D rotates clockwise or counterclockwise within a plane that includes the display surface F in the space in front of the console unit.
[0039] Next, the left-right sliding stage 23 and the left-right sliding stage 24 support the vertical sliding stage 21 so as to be movable in the vertical direction along the vertical guides 22. The vertical sliding motor 15c built into the vertical sliding stage 21 moves the vertical sliding stage 21 along the vertical guides 22 relative to the left-right sliding stage 23 and the left-right sliding stage 24 in order to slide the entire display unit D up and down as seen by the user within a plane that includes the display surface F in the space. As a result, as shown in Fig. 3, the linking arm 20 and the display unit D slide up and down as seen by the user. At this time, the linking arm 20 slides up and down together with the display unit D through the hole HL on the front surface of the housing CK.
[0040] On the other hand, the front-rear sliding stage 25 supports the left-right sliding stage 23 and the left-right sliding stage 24 so that they can move left and right along the guide grooves 25a. The left and right sliding motors 15d built into the left and right sliding stages 23 and 24 move the left and right sliding stages 23 and 24 left and right along the guide grooves 25a relative to the front-rear sliding stage 25 so as to slide the entire display unit D left and right as seen by the user within a plane that includes the display surface F in the above-mentioned space. As a result, as shown in FIG. 3, the up-down sliding stage 21, the connecting arm 20, and the display unit D slide left and right as seen by the user. At this time, the connecting arm 20 slides left and right together with the display unit D through the hole HL on the front surface of the housing CK.
[0041] In addition, by simultaneously driving the up / down slide motor 15c in the up / down slide stage 21 and the left / right slide motor 15d in the left / right slide stage 23 and the left / right slide stage 24, it is also possible to slide the connecting arm 20 and the display unit D in a diagonal direction.
[0042] Next, the front-rear guides 26 and 27 support the front-rear sliding stage 25 so that it can move in the front-rear direction. A front-rear sliding motor 15e built into the front-rear sliding stage 25 moves the front-rear sliding stage 25 in the front-rear direction along each guide groove 27a relative to the front-rear guides 26 and 27 in order to slide the entire display unit D in the front-rear direction as seen by the user in the space described above. As a result, as shown in FIG. 3 , the front-rear sliding stage 25, the left-right sliding stages 23 and 24, the up-down sliding stage 21, the connecting arm 20, and the display unit D slide in the front-rear direction as seen by the user.
[0043] Finally, the optical disc drive DK reads out the map data and the like recorded on an existing optical disc (for example, a DVD (Digital Versatile Disc) or a CD (Compact Disc)) and outputs it to the control unit 3. In this case, the optical disc can be inserted into the optical disc drive DK through an insertion slot SL provided on the front surface of the housing CK.
[0044] Next, the configuration of the touch sensor group TS in the display unit D according to the embodiment will be described in particular with reference to FIG.
[0045] As described above, the touch sensor group TS according to the embodiment is composed of a plurality of touch sensors provided on the peripheral portion of the front surface of the display unit D other than the display surface F, on the top, bottom, left, and right side portions of the display unit D, and on the peripheral portion of the back surface of the display unit D. As described above, each of these touch sensors detects whether or not the touch sensor is touched by the user's finger or hand, the pressure applied when such contact occurs, and any changes in the pressure, and outputs the detection results to the control unit 3.
[0046] First, as shown in FIG. 4(a) as a front view of the display unit D, touch sensors 1a and 1c are provided at both ends of the outer left edge of the display surface F on the front surface of the display unit D, and touch sensor 1b is provided in the longitudinal direction of the center. Note that FIG. 4 does not show the connecting arm 20 fixed to the rear surface of the display unit D. Furthermore, touch sensors 1d and 1f are provided at both ends of the outer right edge of the display surface F on the front surface of the display unit D, and touch sensor 1e is provided in the longitudinal direction of the center. Meanwhile, as shown in FIG. 4(b) as a rear view of the display unit D, touch sensors 2a and 2c are provided at both ends of the right outer edge of the rear surface of the display unit D, which includes the camera 16, and touch sensor 2b is provided in the longitudinal direction of the center. Furthermore, touch sensors 2d and 2f are provided at both ends of the left outer edge of the rear surface of the display unit D, and touch sensor 2e is provided in the longitudinal direction of the center. Due to the above arrangement of touch sensors 1a to 1f (on the front of display unit D) and the arrangement of touch sensors 2a to 2f (on the back of display unit D), when contact is detected by the touch sensors (for example, touch sensor 1a and touch sensor 2a) provided at corresponding positions on the front and back of display unit D, it means that the user is performing the above-mentioned pinching operation on the corresponding position on display unit D.
[0047] On the other hand, as shown in Fig. 4(c) as a top view of display unit D, touch sensors 3a and 3c are provided on both sides of the top surface of display unit D, with touch sensor 3b provided in the center. As shown in Fig. 4(d) as a bottom view of display unit D, touch sensors 4a and 4c are provided on both sides of the bottom surface of display unit D, with touch sensor 4b provided in the center. As shown in Fig. 4(e) as a left side view of display unit D, touch sensors 5a and 5c are provided on both sides of the left side surface of display unit D, with touch sensor 5b provided in the center. Furthermore, as shown in Fig. 4(f) as a right side view of display unit D, touch sensors 6a and 6c are provided on both sides of the right side surface of display unit D, with touch sensor 6b provided in the center.
[0048] In addition to these touch sensors 1a to 6f, the touch panel 14 itself also functions as a touch sensor according to the embodiment. In this case, a touch operation as the position input function is also performed on the touch panel 14. Such a touch operation must be distinguished from the contact according to the embodiment. For this reason, the control unit 3 determines that a contact according to the embodiment has been made on the touch panel 14 when, for example, a contact with an area larger than the contact area of a fingertip or a touch pen used in the touch operation (for example, an area about the size of a palm) has occurred. When the control unit 3 detects a contact with the touch panel 14 with such a large area, it determines that the contact is a contact by a user according to the embodiment, and controls the position of the entire display unit D.
[0049] Next, the structure and function of the fixing unit 17 according to the embodiment, which is provided on the back surface of the display unit D, will be described with reference to Fig. 5. For simplicity of description, the touch sensors 2a and the like on the back surface and side surfaces of the display unit D and the protective cover for the fixing unit 17 are omitted from Fig. 5. As described above, the fixing unit 17 according to the embodiment is a fixing unit that physically (mechanically) fixes the display unit D to the connecting arm 20. Under the control of the fixation control unit 18, the fixing unit 17 mechanically fixes the display unit D to the connecting arm 20 and also makes the display unit D detachable from the connecting arm 20 to which it is fixed.
[0050] 5, a receiving portion 20a is fixed to the end of the connecting arm 20 opposite the housing CK. The receiving portion 20a has a shape that fits into a recess 40 formed in the center of the back surface of the display unit D. Two through holes, 20b and 20c, are formed in parallel in the left-right direction from the receiving portion 20a toward the display unit D when the receiving portion 20a is fitted into the recess 40.
[0051] In contrast, the movable member 30 constituting the fixed portion 17 is formed with guide holes 30a and 30b through which guide pins 31 and 32, respectively, pass. The guide pins 31 and 32 are fixed to the left side of the recess 40 facing the rear surface of the display unit D. The ends of the guide pins 31 and 32 opposite the ends fixed to the display unit D are formed with dish-shaped fasteners for guiding the left-right movement of the movable member 30. Furthermore, parallel fixed rods 30d and 30e are inserted into the through holes 20b and 20c from the left side facing the display unit D when the display unit D is fixed to the connecting arm 20. These fixed rods are integrally formed at positions on the movable member 30 corresponding to the positions of the through holes 20b and 20c when the display unit D is fixed. Furthermore, a rack 30c is integrally formed on the upper part of the movable member 30. A pinion 34 engaging with the rack 30c is fixed to its rotation shaft. A fixed motor 33 constituting the fixed portion 17 is fixed to the upper part of the movable member 30 on the rear surface of the display unit D in FIG. 5 . The pinion 34 is fixed to the rotation shaft of the fixed motor 33. When the fixed motor 33 is driven under the control of the fixation control unit 18 with the pinion 34 meshing with the rack 30c, the rotation of the pinion 34 causes the moving member 30 to move left and right along the guide holes 30a and 30b. At this time, if the moving member 30 is moved rightward in FIG. 5 with the receiving portion 20a fitted in the recess 40, the fixing rods 30d and 30e are inserted from the left side into the through holes 20b and 20c of the receiving portion 20a, respectively. As a result, the display unit D is fixed to the connecting arm 20 via the receiving portion 20a.
[0052] Meanwhile, guide holes 35a and 35b are formed in the moving member 35 constituting the fixed portion 17, through which guide pins 36 and 37, respectively, pass. The guide pins 36 and 37 are fixed to the right side of the recess 40 facing the rear surface of the display unit D. Disk-shaped fastening portions for guiding the left-right movement of the moving member 35 are formed on the ends of the guide pins 36 and 37 opposite the ends fixed to the display unit D. Furthermore, parallel fixing rods 35d and 35e are integrally formed at positions on the moving member 35 corresponding to the positions of the through holes 20b and 20c when fixed. A rack 35c is integrally formed on the upper part of the moving member 35. A pinion 39 meshing with the rack 35c is fixed to its rotation shaft. A fixed motor 38, constituting the fixed portion 17, is fixed to the upper part of the moving member 35 on the rear surface of the display unit D in FIG. 5 . When the fixed motor 38 is driven under the control of the fixation control unit 18 with the pinion 39 meshing with the rack 35c, the rotation of the pinion 39 causes the moving member 35 to move left and right along the guide holes 35a and 35b. At this time, if the moving member 35 is moved leftward in FIG. 5 with the receiving portion 20a fitted in the recess 40, the fixing rods 35d and 35e are inserted from the right side into the through holes 20b and 20c of the receiving portion 20a, respectively. This, coupled with the movement of the moving member 30 on the opposite side of the recess 40, fixes the display unit D to the connecting arm 20 via the receiving portion 20a.
[0053] In addition, in a state in which display unit D is fixed to connecting arm 20 via receiving portion 20a by fixing portion 17, when fixing motor 33 and fixing motor 38 are driven in the reverse direction to the rotation when fixed under the control of fixing control portion 18, moving member 30 is moved leftward in Fig. 5 along guide holes 30a and 30b, and in parallel with this, moving member 35 is moved rightward in Fig. 5 along guide holes 35a and 35b. As a result, fixing rods 30d and 30e and fixing rods 35d and 35e are pulled out leftward or rightward in Fig. 5 from through holes 20b and 20c of receiving portion 20a, respectively, and display unit D becomes detachable from connecting arm 30.
[0054] Next, the manner in which the navigation device NV including the drive unit 15 (including the optical disc drive DK) and the display unit D (see Figure 3) is attached to the console section of the vehicle in which the navigation device NV of the embodiment is installed will be explained using Figure 6.
[0055] As shown in Fig. 6, the navigation device NV according to the embodiment is mounted in a central area 50 of the console unit. An opening 51 for mounting the navigation device NV and the like is provided in the central area 50 of the console unit. The drive unit 15 and the like of the navigation device NV are inserted and fixed to the console unit through this opening 51, thereby fixing the navigation device NV to the console unit.
[0056] The central region 50 of the console unit is provided with, for example, a hazard switch 52, a clock display 53, an air conditioner switch 54, a thermometer display 55, a wind speed adjustment dial 56, a temperature adjustment dial 57, an air outlet selection dial 58, and an outside / inside air selector switch 59. Of these, the hazard switch 52 is a switch for flashing and turning off the hazard lights installed in the vehicle. The clock display 53 has a display that displays the current time. The temperature display 55 has a display that displays the detected temperature inside the vehicle. The air conditioner switch 54 to the outside / inside air selector switch 59 are each operating units for controlling the operation of the air conditioner installed in the vehicle. The types of operating units installed in the central region 50 of the console unit and the types of information displayed by the devices installed in the central region 50 generally vary depending on the vehicle model and year of manufacture. Furthermore, the arrangement of the opening 51, operating units, and devices in the central region 50 of the console unit also generally varies depending on the vehicle model and year of manufacture. 6, the height and width of the display unit D according to the embodiment are greater than the height and width of the drive unit 15 and the opening 51. Therefore, depending on the position of the display unit D relative to the drive unit 15 and whether the display unit D is in portrait or landscape orientation, at least one of the hazard switch 52 to the outside / inside air selector switch 59 on the central region 50 may be hidden behind the display unit D. Also, the insertion slot SL of the optical disk drive DK may be hidden behind the display unit D. Therefore, by moving or rotating the display unit D using the drive unit 15 according to the embodiment, the parts hidden behind the display unit D become visible to the user. Similarly, it becomes possible to operate the hazard switch 52, the outside / inside air selector switch 59, or the insertion slot SL that are hidden behind the display unit D.
[0057] Next, the control of rotation or movement of the display unit D according to the embodiment, which is executed under the control of the control unit 3 by the drive unit 15 according to the embodiment having the above-described configuration, will be described collectively with reference to Figs. 7 to 9. In the following description using Figs. 7 to 9, it is assumed that the display unit D is fixed to the connecting arm 20 by the fixing unit 17. The control of rotation or movement shown in Fig. 7 may be started as a time-sharing interrupt process at regular intervals, for example, as part of the above-described guidance process of the navigation device NV.
[0058] 7, in controlling the rotation or movement of the display unit D according to the embodiment, the control unit 3 monitors whether or not a touch by the user according to the embodiment is detected on any of the touch sensors 1a to 6f and the touch panel 14 provided on the surface of the display unit D (steps S1 and S2). If the touch is not detected on any of the touch sensors 1a and the like during the monitoring in steps S1 and S2 (step S2: NO), the control unit 3 returns to the original guidance process.
[0059] On the other hand, if the contact is detected in either of the touch sensors 1a, etc. in the monitoring of steps S1 and S2 (step S2: YES), the control unit 3 then determines whether or not the contact is detected in two touch sensors 1a, etc. (e.g., touch sensor 1a and touch sensor 2a) located at corresponding positions on the front and back of the display unit D (step S3). If the determination in step S3 does not detect the contact in two touch sensors 1a, etc. located at corresponding positions on the front and back of the display unit D (step S3: NO), the control unit 3 proceeds to the determination in step S11, which will be described later. On the other hand, if the determination in step S3 detects the contact in two touch sensors 1a, etc. located at corresponding positions on the front and back of the display unit D (step S3: YES), the control unit 3 then determines whether or not the contact pattern on the front and back is the pinch contact pattern (step S4). In the judgment of step S4, the control unit 3 reads the pinch contact pattern data from the recording unit 11 when the judgment of step S3 is "YES", and makes a judgment by comparing it with the contact pattern detected at that time (see step S3: YES).
[0060] If it is determined in step S4 that the contact pattern detected in step S3 is not the pinch contact pattern (step S4: NO), the control unit 3 returns to the original guidance process. On the other hand, if it is determined in step S4 that the contact pattern detected in step S3 is the pinch contact pattern (step S4: YES), the control unit 3 next determines whether there is a difference between the pressure of the contact on the front surface of the display unit D and the pressure of the contact on the corresponding position on the back surface of the display unit D, the difference being equal to or greater than, for example, a preset threshold (step S5). At this time, the preset threshold is a threshold that can prevent the determination in step S5 from becoming "YES" if the contact having the pinch contact pattern is due to an erroneous operation, and more specifically, is set in advance, for example, experimentally or empirically. In the judgment of step S5, if there is a difference between the pressure of the contact on the front surface of the display unit D and the pressure of the contact on the corresponding position on the back surface of the display unit D that is equal to or greater than the predetermined threshold (step S5: YES), the control unit 3 determines that the contact on the front and back surfaces of the display unit D by the pinch contact pattern is based on the user's intention to move the display unit D forward or backward as seen from the user, and controls the drive unit 15 to move the display unit D in the direction opposite to the surface of the display unit D where the contact with the greater pressure was detected (step S6). Pressing force of contact on the front of the display D > pressing force of contact on the corresponding position on the back of the display D In this case, the control unit 3 controls the drive unit 15 so as to move the display unit D backward as viewed from the user (i.e., in a direction closer to the drive unit 15 (console unit)). The pressure of contact on the front of the display D < the pressure of contact on the corresponding position on the back of the display D In this case, the drive unit 15 is controlled so as to move the display unit D forward as viewed from the user (that is, in a direction away from the drive unit 15 (console unit)).
[0061] Thereafter, the control unit 3 determines whether or not to stop the movement in step S6 (step S7). At this time, the control unit 3 determines that the movement in step S6 should be stopped if either one of the contacts in the pinch contact pattern (either contact on the front surface or contact on the back surface of the display unit D) is no longer detected. On the other hand, if the contact in the pinch contact pattern is continuously detected, the control unit 3 determines that the movement in step S6 should be continued. In the determination in step S7, if it is determined that the movement in step S6 should be continued (step S7: continue), the control unit 3 returns to step S5 and repeats the above-described control from step S5 onwards. In the determination in step S7, if it is determined that the movement in step S6 should be stopped (step S7: stop), the control unit 3 stops the movement of the display unit D and returns to the original guidance processing.
[0062] On the other hand, if the judgment in step S5 above shows that there is no difference between the pressure of the contact on the front of the display unit D and the pressure of the contact on the corresponding position on the back of the display unit D that is greater than or equal to the predetermined threshold, i.e., if the pressure of the contact on the front of the display unit D and the pressure of the contact on the corresponding position on the back of the display unit D are equal (step S5: NO), the control unit 3 next checks the positions on the display unit D of the touch sensors 1a, etc. where the contacts corresponding to the pinch contact pattern were detected in step S4 (step S8), and further detects the change in the position where the pressure was detected as the pressure direction of the contact as the change in the pressure of the contact (step S9).
[0063] In step S8, if a contact corresponding to a pinch contact pattern is detected between touch sensor 1e and touch sensor 2e on the rear side thereof, the control unit 3 confirms that a contact corresponding to a pinch contact pattern with an equivalent pressure force (i.e., no difference of more than the predetermined threshold; the same applies below) is detected at the right outer edge in the front view of Fig. 4(a). Also, if a contact corresponding to a pinch contact pattern is detected between touch sensor 1a and touch sensor 2a on the rear side thereof, the control unit 3 confirms that a contact corresponding to a pinch contact pattern with an equivalent pressure force is detected at the upper left end in the front view of Fig. 4(a).
[0064] On the other hand, in step S9, when a contact corresponding to a pinch contact pattern is detected on touch sensor 1e and touch sensor 2e on the back surface thereof, control unit 3 detects the change in the position where the pressure is detected on touch sensor 1e and touch sensor 2e as the pressure direction of each contact. Also, when a contact corresponding to a pinch contact pattern is detected on touch sensor 1a and touch sensor 2a on the back surface thereof, control unit 3 detects the change in the position where the pressure is detected on touch sensor 1a and touch sensor 2a as the pressure direction of each contact.
[0065] Then, the control unit 3 controls the drive unit 15 to either rotate the display unit D, move the display unit D to the left or right when viewed from the front, or move the display unit D upward or downward when viewed from the front, in accordance with the contact position on the display unit D confirmed in step S8 and the pressing direction detected in step S9 (step S10).
[0066] Thereafter, the control unit 3 determines whether or not to stop the movement in step S10 (step S7). At this time, the control unit 3 determines that the rotation or movement in step S10 should be stopped if any one of the contacts of the pinch contact patterns is no longer detected, as in the case of step S7 after step S6 described above. On the other hand, if the contact of the pinch contact pattern continues, the control unit 3 determines that the rotation or movement in step S10 should be continued. In the determination of step S7, if it is determined that the rotation or movement in step S10 should be continued (step S7: continue), the control unit 3 returns to step S5 and repeats the above-described control from step S5 onwards. In the determination of step S7, if it is determined that the rotation or movement in step S10 should be stopped (step S7: stop), the control unit 3 stops the movement of the display unit D and returns to the original guidance processing.
[0067] As a result of the above-described control of step S5 and steps S8 to S10, if a contact corresponding to a pinch contact pattern with an equivalent pressure is confirmed at the right outer edge in the front view of Fig. 4(a) (see step S8), and the pressing direction of the contact is to the right in the front view of Fig. 4(a) (i.e., when an operation of pinching the right outer edge and pulling it outward is performed), the control unit 3 controls the drive unit 15 to move the display unit D to the right as seen from the front, as exemplified in Fig. 8(a). Similarly, if a contact corresponding to a pinch contact pattern with an equivalent pressure is detected at the right outer edge in the front view of Fig. 4(a) (see step S8), and the pressing direction of the contact is to the left as seen from the front (i.e., when an operation of pinching the right outer edge and pushing it toward the center of the display unit D is performed), the control unit 3 controls the drive unit 15 to move the display unit D to the left as seen from the front, as exemplified in Fig. 8(a). Furthermore, for example, when contact corresponding to a pinch contact pattern is detected between touch sensor 1b and touch sensor 2b on the back surface thereof, contact corresponding to a pinch contact pattern with an equivalent pressure is confirmed at the left outer edge in the front view of Figure 4(a) (see step S8), and the pressure direction of the contact is to the right in the front view of Figure 4(a) (i.e., when an operation is performed to pinch the left outer edge and press toward the center of display unit D), control unit 3 controls drive unit 15 to move display unit D to the right when viewed from the front, as illustrated in Figure 8(b). Similarly, when a contact corresponding to a pinching contact pattern with the same pressure force is detected at the left outer edge in the front view of Figure 4(a) (see step S8), and the pressure direction of the contact is to the left in the front view of Figure 4(a) (i.e., when an operation is performed to pinch the left outer edge and pull it outward), the control unit 3 controls the drive unit 15 to move the display unit D to the left when viewed from the front, as illustrated in Figure 8(b).
[0068] Furthermore, for example, when contact corresponding to a pinch contact pattern is detected between touch sensor 1d and touch sensor 2d on the back side thereof, contact corresponding to a pinch contact pattern with an equivalent pressure is confirmed at the upper right end in the front view of Figure 4(a) (see step S8), and the pressure direction of the contact is counterclockwise or upper left in the front view of Figure 4(a) (i.e., when the upper right end is pinched and the operation of turning the display unit D counterclockwise is performed), the control unit 3 controls the drive unit 15 to rotate the display unit D counterclockwise when viewed from the front, as illustrated in Figure 8(c). Similarly, if a contact corresponding to a pinch contact pattern with the same pressure force is confirmed at the upper right end in the front view of Figure 4(a) (see step S8), and the pressure direction of the contact is clockwise or downward and to the right in the front view of Figure 4(a) (i.e., if an operation is performed to pinch the upper right end and rotate the display unit D clockwise), the control unit 3 controls the drive unit 15 to rotate the display unit D clockwise when viewed from the front, as illustrated in Figure 8(c). Furthermore, for example, when contact corresponding to a pinch contact pattern is detected between touch sensor 1a and touch sensor 2a on the backside thereof, contact corresponding to a pinch contact pattern with an equivalent pressure is confirmed at the upper left end in the front view of Figure 4(a) (see step S8), and the pressure direction of the contact is counterclockwise or downward and left in the front view of Figure 4(a) (i.e., when the upper left end is pinched and the operation of turning display unit D counterclockwise is performed), control unit 3 controls drive unit 15 to rotate display unit D counterclockwise when viewed from the front, as illustrated in Figure 8(d). Similarly, if a contact corresponding to a pinch contact pattern with the same pressure force is confirmed at the upper left end in the front view of Figure 4(a) (see step S8), and the pressure direction of the contact is clockwise or upper right in the front view of Figure 4(a) (i.e., if an operation is performed to pinch the upper left end and rotate the display unit D clockwise), the control unit 3 controls the drive unit 15 to rotate the display unit D clockwise when viewed from the front, as illustrated in Figure 8(d).
[0069] On the other hand, if the determination in step S3 above does not detect the contact on the two touch sensors 1a, etc., located at corresponding positions on the front and back of the display unit D (step S3: NO), the control unit 3 then determines whether the contact is detected on only one of the touch sensors 3a to 6c provided on the (peripheral) side of the display unit D or the touch panel 14 (step S11). If the determination in step S11 does not detect the contact on any of the touch sensors 3a to 6c and the touch panel 14 (step S11: NO), the control unit 3 proceeds to the determination in step S18, which will be described later. On the other hand, if the determination in step S11 above detects the contact on any one of the touch sensors 3a to 6c or the touch panel 14 (step S11: YES), the control unit 3 detects the pressure of the contact via the touch panel 3a, etc., on which the contact was detected (step S12). Next, the control unit 3 determines whether the pressure detected in step S12 is equal to or greater than the first threshold (step S13). If it is determined in step S13 that the pressure detected in step S12 is equal to or greater than the first threshold (step S13: YES), the control unit 3 controls the drive unit 15 to rotate or move the display unit D in a first direction corresponding to the pressure equal to or greater than the first threshold for the touch sensor 3a or the like where the contact at the single point was detected (step S14). The control unit 3 then determines whether to stop the rotation or movement of step S14 (step S15). At this time, if the contact at the single point is no longer detected, the control unit 3 determines that the rotation or movement of step S14 should be stopped. On the other hand, if the contact at the single point is still detected, the control unit 3 determines that the rotation or movement of step S14 should be continued. If it is determined in step S15 that the rotation or movement of step S14 should be continued (step S15: CONTINUE), the control unit 3 returns to step S12 and repeats the above-described control from step S12 onwards. On the other hand, in the determination at step S15, if it is determined that the rotation or movement at step S14 should be stopped (step S15: stop), the control unit 3 stops the movement of the display unit D and returns to the original guidance processing.
[0070] On the other hand, if the determination in step S13 is that the pressure detected in step S12 is not equal to or greater than the first threshold (step S13: NO), the control unit 3 then determines whether the pressure detected in step S12 is equal to or less than the second threshold (step S16). As described above, the second threshold is smaller than the first threshold. If the determination in step S16 is that the pressure detected in step S12 is not equal to or less than the second threshold (step S16: NO), the control unit 3 returns to the original guidance process without rotating or moving the display unit D. On the other hand, if the determination in step S16 is that the pressure detected in step S12 is equal to or less than the second threshold (step S16: YES), the control unit 3 controls the drive unit 15 to rotate or move the display unit D in the second direction corresponding to the pressure equal to or less than the second threshold for the touch sensor 3a, etc., where contact at one point was detected (step S17). The control unit 3 then proceeds to the determination in step S15. At this time, if the contact at one point is no longer detected, the control unit 3 determines that the rotation or movement at step S17 should be stopped. On the other hand, if the contact at one point is continuously detected, the control unit 3 determines that the rotation or movement at step S17 should be continued. If it is determined in the determination at step S15 that the rotation or movement at step S17 should be continued (step S15: continue), the control unit 3 returns to step S12 and repeats the above-described control from step S12 onwards. On the other hand, if it is determined in the determination at step S15 that the rotation or movement at step S17 should be stopped (step S15: stop), the control unit 3 stops the movement of the display unit D and returns to the original guidance processing.
[0071] As a result of the control of steps S11 to S17 described above, if contact is confirmed at one point on touch sensor 5b in the left side view of FIG. 4(e) (step S11: YES, see the "contact" arrow in FIG. 9(a)), the second direction for touch sensor 5b is the left direction shown in FIG. 9(a), and the first direction is the right direction shown in FIG. 9(a). If the pressure applied to touch sensor 5b is equal to or less than a second threshold, control unit 3 controls drive unit 15 to move display unit D leftward as viewed from the front, as illustrated in FIG. 9(a). Similarly, if the pressure applied to touch sensor 5b is equal to or greater than the first threshold, control unit 3 controls drive unit 15 to move display unit D rightward as viewed from the front, as illustrated in FIG. 9(a). Furthermore, if contact is confirmed at one point on the touch sensor 6b in the right side view of FIG. 4(f) (step S11: YES, see the "contact" arrow in FIG. 9(b)), the second direction for the touch sensor 6b is the right direction shown in FIG. 9(b), and the first direction is the left direction shown in FIG. 9(b). If the pressure of the contact on the touch sensor 6b is equal to or less than the second threshold, the control unit 3 controls the drive unit 15 to move the display unit D to the right as viewed from the front, as illustrated in FIG. 9(b). Similarly, if the pressure of the contact on the touch sensor 6b is equal to or greater than the first threshold, the control unit 3 controls the drive unit 15 to move the display unit D to the left as viewed from the front, as illustrated in FIG. 9(b).
[0072] Furthermore, if contact is confirmed at one point on the touch sensor 3b in the top view of FIG. 4(c) (step S11: YES, see the "contact" arrow in FIG. 9(c)), the second direction for the touch sensor 3b is the upward direction shown in FIG. 9(c), and the first direction is the downward direction shown in FIG. 9(c). If the pressure of the contact on the touch sensor 3b is equal to or less than the second threshold, the control unit 3 controls the drive unit 15 to move the display unit D upward when viewed from the front, as illustrated in FIG. 9(c). Similarly, if the pressure of the contact on the touch sensor 3b is equal to or greater than the first threshold, the control unit 3 controls the drive unit 15 to move the display unit D downward when viewed from the front, as illustrated in FIG. 9(c).
[0073] Furthermore, for example, if contact is confirmed at one point on the touch sensor 6a in the right side view of FIG. 4(f) (step S11: YES, see the "contact" arrow in FIG. 9(d)), the second direction for the touch sensor 6a is the clockwise direction shown in FIG. 9(d), and the first direction is the counterclockwise direction shown in FIG. 9(d). If the pressure of the contact on the touch sensor 6a is equal to or less than the second threshold, the control unit 3 controls the drive unit 15 to rotate the display unit D in the clockwise direction as viewed from the front, as illustrated in FIG. 9(d). Similarly, if the pressure of the contact on the touch sensor 6a is equal to or greater than the first threshold, the control unit 3 controls the drive unit 15 to rotate the display unit D in the counterclockwise direction as viewed from the front, as illustrated in FIG. 9(d).
[0074] Furthermore, if contact is confirmed at one location on the touch panel 14 (step S11: YES, see the "contact" arrow in FIG. 9(e)), the second direction for the touch panel 14 is the forward direction (the direction from the drive unit 15 toward the display unit D) shown in FIG. 9(e), and the first direction is the backward direction (the direction from the display unit D toward the drive unit 15) shown in FIG. 9(e). If the pressure of the contact on the touch panel 14 is equal to or less than a second threshold, the control unit 3 controls the drive unit 15 to move the display unit D forward, as exemplified in FIG. 9(e). Similarly, if the pressure of the contact on the touch panel 14 is equal to or greater than the first threshold, the control unit 3 controls the drive unit 15 to move the display unit D backward, as exemplified in FIG. 9(e).
[0075] On the other hand, if the determination in step S11 above indicates that the contact is not detected at only one location, such as the touch sensor 3a (step S11: NO), the control unit 3 next determines whether or not the contact is detected at two locations on the front and two locations on the back of the display unit D (four locations in total) or more of the touch sensors 1a, etc. (for example, touch sensors 1b and 1e (on the front of the display unit D), and touch sensors 2b and 2e (on the back of the display unit D)) (step S18). If the determination in step S18 indicates that the contact is not detected at four or more touch sensors 1a, etc. (step S18: NO), the control unit 3 returns to the original guidance process.
[0076] On the other hand, if the determination in step S18 indicates that the contacts are detected at the four or more touch sensors 1a, etc. (step S18: YES), the control unit 3 then determines whether the contact patterns on the front and back surfaces are the gripping contact pattern (step S19). In the determination in step S19, the control unit 3 reads the gripping contact pattern data from the recording unit 11 at the time when the determination in step S18 is "YES," and makes a determination by comparing it with the contact pattern detected at that time (see step S18: YES).
[0077] If it is determined in step S19 that the contact pattern detected in step S18 is not the gripping contact pattern (step S19: NO), the control unit 3 returns to the original guidance process. On the other hand, if it is determined in step S19 that the contact pattern detected in step S18 is the gripping contact pattern (step S19: YES), the control unit 3 then drives the fixed motors 33 and 38 of the fixed unit 17 via the fixing control unit 18 to move the movable members 30 and 35 in directions away from the center of the rear surface of the display unit D. As a result, the fixed rods 30d and 30e and the fixed rods 35d and 35e are removed from the through holes 20b and 20c, respectively, and the display unit D, which has been fixed to the receiving unit 20a, becomes detachable from the connecting arm 20 while still being gripped by the user (see step S19: YES above) (step S20). The control unit 3 then returns to the original guidance process.
[0078] The display unit D detached from the connecting arm 20 is used for processing unrelated to the function of the navigation device NV, such as displaying a video in the rear seat. At this time, the distance between the navigation device NV and the display unit D after detaching from the connecting arm 20 may be detected using, for example, a wireless distance sensor, and when the detected distance is equal to or greater than a preset distance (for example, one meter), the unrelated processing may be started.
[0079] Next, a process executed by the display unit D when the display unit D, which has been detached from the connecting arm 20 through step S20, is fixed to the connecting arm 20 again will be described with reference to Fig. 10. The process shown in the flowchart in Fig. 10 is executed mainly by the fixing control unit 18 and the display control unit 19 of the display unit D.
[0080] 10, after the display unit D is detached from the connecting arm 20, the display control unit 19 monitors whether a preset instruction operation to fix the display unit D to the connecting arm 20 again has been performed, for example, on the touch panel 14 (step S25). If the instruction operation has not been performed in the monitoring of step S25 (step S25: NO), the display control unit 19 determines whether, for example, the power supply of the display unit D has been turned off (step S29). If the determination in step S29 indicates that the power supply is turned off (step S29: YES), the display control unit 19 and the fixing control unit 18 each terminate their respective processes. On the other hand, if the determination in step S29 indicates that the power supply is not turned off (step S29: NO), the display control unit 19 returns to the determination in step S25.
[0081] On the other hand, if the instruction operation is executed during the monitoring in step S25 (step S25: YES), the display control unit 19 activates the camera 16 to capture an image of the imaging range facing the back surface of the display unit D and displays the captured image on the display surface F (step S26). This allows the user holding the display unit D to use the image of the receiving portion 20a appearing in the displayed captured image as a clue to move the display unit D itself to a fixed position on the connecting arm 20. Thereafter, the display control unit 19 and the fixation control unit 18 monitor whether or not the fixation of the display unit D to the connecting arm 20 by the fixation unit 17 has been completed (step S27). If the fixation has not been completed during the monitoring in step S27 (step S27: NO), the display control unit 19 and the fixation control unit 18 return to step S26. On the other hand, if the fixation has been completed during the monitoring in step S27 (step S27: YES), the display control unit 19 stops driving the camera 16 and stops displaying the captured image on the display surface F (step S28). Thereafter, the display control unit 19 and the fixed control unit 18 proceed to the determination in step S29.
[0082] As described above, according to the rotation / movement control of the display unit D in the embodiments, the rotation or movement of the display unit D is controlled in either a first direction relative to the housing CK or a second direction different from the first direction based on the pressure applied by contact with the display unit D (see steps S14 and S15 in Figure 7), so that the display unit D can be freely rotated or moved with a simple operation.
[0083] Furthermore, if the detected pressure is equal to or greater than a first threshold, the rotation or movement of the display unit D in a first direction is controlled (see step S14 in FIG. 7), and if the detected pressure is equal to or less than a second threshold that is smaller than the first threshold, the rotation or movement of the display unit D in a second direction opposite to the first direction is controlled (see step S17 in FIG. 7), so that the display unit D can be freely rotated or moved in each direction by adjusting the pressure. Furthermore, because the second threshold is smaller than the first threshold, a so-called dead zone can be formed between the first and second thresholds, and rotation or movement of the display unit D due to malfunction can be suppressed.
[0084] Furthermore, when the first direction is a direction that moves the display unit D closer to the housing CK and the second direction is a direction that moves the display unit D away from the housing CK, and the movement of the display unit D in the direction that moves it closer to or away from the housing CK is controlled, the display unit D can be freely moved in the direction that moves it closer to or away from the housing CK.
[0085] Furthermore, when the first direction and the second direction are either (i) the first direction is either the vertically upward direction or the vertically downward direction with respect to the housing CK, and the second direction is the other of the vertically upward direction or the vertically downward direction, or (ii) the first direction is either the rightward direction or the leftward direction with respect to the housing CK, and the second direction is the other of the rightward direction or the leftward direction, by controlling the movement of the display unit D in the first direction or the second direction, it is possible to freely move the display unit D in either the vertically upward direction or the vertically downward direction with respect to the housing CK. Note that the above effect is similar when the first direction is one diagonal direction with respect to the housing CK, and the second direction is the other diagonal direction.
[0086] Furthermore, when the first direction is either a clockwise or counterclockwise direction in rotation toward the housing CK, and the second direction is the other of the clockwise or counterclockwise directions, the display unit D can be freely rotated relative to the housing CK by controlling the rotation of the display unit D in the first direction or the second direction.
[0087] Furthermore, the display unit D can be rotated or moved in multiple directions, and the first and second directions are set based on the position of contact on the display unit D, so the direction of rotation or movement of the display unit D can be freely set according to the user's intentions.
[0088] Furthermore, if the pressure is no longer detected after control of the rotation or movement of the display unit D has started, the control is stopped (see step S15 in Figure 7), so the display unit D can be rotated or moved more freely based on the user's intention, and can also be stopped.
[0089] Furthermore, when the pressure of contact with the touch panel 14 is used, the display unit D can be conveniently and easily moved back and forth relative to the housing CK.
[0090] In addition to the configuration of the above-described embodiment, the display unit D may be rotated or moved based on the pressure of contact on touch sensors 1a to 1f provided on the front surface of the display unit D. In this case, for example, when a contact with a pressure equal to or less than a corresponding second threshold is detected for touch sensor 1e shown in FIG. 4(a), the drive unit 15 may be controlled to move the display unit D to the right (second direction) in FIG. 4(a). When a contact with a pressure equal to or greater than a corresponding first threshold is detected for touch sensor 1e shown in FIG. 4(a), the drive unit 15 may be controlled to move the display unit D to the left (first direction) in FIG. 4(a). Also, when a contact with a pressure equal to or less than a corresponding second threshold is detected for touch sensor 1d shown in FIG. 4(a), the drive unit 15 may be controlled to rotate the display unit D in the counterclockwise direction (second direction) in FIG. 4(a). When a contact with a pressure equal to or greater than a corresponding first threshold is detected for touch sensor 1d, the drive unit 15 may be controlled to rotate the display unit D in the clockwise direction (first direction) in FIG. 4(a).
[0091] In addition to the configuration of the above-described embodiment, when contact with a predetermined portion of the display unit D is detected continuously for a predetermined time (for example, 1 second) or more, the control of rotation or movement in steps S11 to S17 of FIG. 7 (in other words, control as a display unit rotation / movement mode) may be started, and further, the first threshold value and the second threshold value may be set based on the pressure detected during the predetermined time. In this case, the display unit D can be rotated or moved more freely based on the user's intention. That is, by switching to the display unit rotation / movement mode when contact with the predetermined portion of the display unit D is detected continuously for more than the predetermined time, it is possible to prevent switching to the display unit rotation / movement mode due to contact unintentionally by the user. Then, the average value of the pressure due to the contact within the predetermined time is calculated, and using the average value as a reference, for example, The average value × 1.5 = the first threshold value (Formula 1) The average value × 0.5 = the second threshold value (Equation 2) It may be configured to set the above. Here, it is considered that a user generally has a habit of either pressing hard (unconsciously pressing hard) or pressing lightly (unconsciously pressing lightly). Therefore, the user's standard pressing force (e.g., equivalent to the average value of the pressing force) may be measured when the user makes a contact to switch to the display unit rotation / movement mode (to call up the display unit rotation / movement mode), and the first threshold value and the second threshold value may be set, for example, using the measured pressing force as a reference, according to the above formulas (1) and (2) (i.e., to set whether the pressing force is strong or weak). This makes it possible to set the first threshold value and the second threshold value suitable for the user.
[0092] Furthermore, from the viewpoint of preventing erroneous operation, the control of rotation or movement in steps S11 to S17 in Fig. 7 may be configured to be performed only when a preset contact pattern (for example, simultaneous contact by two fingers) is detected in the determination of step S7 in Fig. 7. In this case, when detecting contact by multiple fingers, the pressure of the contact with the greatest pressure among the contacts by the fingers may be used, or the average pressure of the contacts by the multiple fingers may be used.
[0093] Furthermore, in consideration of the fact that the navigation device NV including the drive unit 15 and the display unit D is mounted on a vehicle, the first threshold value and the second threshold value may be corrected based on vibration of the display unit D accompanying the movement of the vehicle, etc. (more specifically, the correction may be made so as to cancel out changes in pressing force due to the vibration). In this case, the display unit D can be rotated or moved while excluding the influence of vibration applied to the display unit D.
[0094] In the above-described embodiment, the pressing direction in step S9 of Fig. 7 is detected as a change in the position where the pressing force is detected, but the pressing direction may alternatively be detected by detecting the direction of the load applied by the user's finger or hand rest using a load sensor (not shown) provided in the receiving portion 20a shown in Fig. 5. Alternatively, the position of contact with the touch sensor 1a or the like may remain unchanged, but the pressing direction may be detected by detecting a change in the load on the finger or hand rest at that position using the touch sensor 1a or the like.
[0095] In the above-described embodiment, the display unit D itself is configured to move forward or backward relative to the drive unit 15 by contact pressure on the touch panel 14 (see Figure 9(e)). However, in addition to this, the display unit D itself can also be configured to move forward or backward based on the comparison result between the contact pressure on any of the touch sensors 2a to 2f provided on the back surface of the display unit D and two preset threshold values.
[0096] Furthermore, the display unit D may be configured to tilt itself upward or downward about a horizontal axis passing through the center of the display unit D, or tilt itself left or right about a vertical axis passing through the center of the display unit D (i.e., to "tilt" in the up-down or left-right direction) based on the comparison result between the pressure due to contact with either the touch sensor 1a or the like provided on the front surface of the display unit D or the touch sensor 2a or the like provided on the back surface of the display unit D and two preset thresholds. In this case, for example, the display unit D may be configured to tilt backward (i.e., in the direction in which the display surface F faces upward) when the touch sensor 1a is contacted with a pressure greater than a preset threshold, and tilt forward (i.e., in the direction in which the display surface F faces downward) when the touch sensor 1a is contacted with a pressure less than another threshold that is smaller than the preset threshold.
[0097] Furthermore, when re-fixing the display unit D to the connecting arm 20 shown in Figure 10, magnetic force can be exchanged between the fixing part 17 and the receiving part 20a at the end of the connecting arm 20, and when predetermined magnetic force patterns are detected from each other, the connecting arm 20 including the receiving part 20a can be moved (driven) so that the receiving part 20a approaches the display unit D that is being brought close to it.
[0098] In addition, a program corresponding to the flowchart shown in Figure 7 can be recorded on a recording medium such as an optical disk or a hard disk, or obtained via a network such as the Internet, and then read out and executed by a general-purpose microcomputer or the like, thereby causing the microcomputer or the like to function as the control unit 3 of the embodiment.
