Description

  The present invention relates to an information device including a display and a key input unit as a user interface.

  In recent years, various types of portable information devices such as smartphones, PDAs (Personal Digital Assistants), electronic books, and netbooks have become widespread. Such a portable information device includes a display and a key input unit such as a keyboard and a touch pad as a user interface, and can execute various application software.

  A portable information device is forced to have structural restrictions as compared with a stationary information device such as a desktop personal computer. A portable information device requires a reduction in the volume of the entire device in order to improve portability. As a result, since the surface area of the device is reduced, the size of the display must be reduced, resulting in poor visibility as viewed from the user. Similarly, since the size of the keyboard or touchpad as the key input unit must be reduced, the operability is also inferior.

  On the other hand, in recent years, tablet computers (also referred to as smart books and slate terminals) equipped with a touch panel display in which a display and a key input unit are integrated have become widespread (for example, see Patent Document 1). The user can perform key input by touching the touch panel display with a finger (or stylus pen). In this case, a touch panel display can be arranged on the front surface on the user side in the portable information device, and the visibility seen from the user is excellent. Moreover, virtual buttons of various functions can be virtually configured on the display depending on the application. Therefore, the installation of a physical keyboard can be omitted, and the display area can be increased by that amount.

  There is also a small electronic device provided with a display and a touch panel on the user-side front surface (for example, see Patent Document 2). There is also a small electronic device that can be operated with one hand by providing a display on the front side of the user and a touch panel on the back side (see, for example, Patent Document 3).

  Furthermore, there is a technique for giving the user a sense of pressing the touch panel display by sinking the operation surface by a predetermined stroke in the internal direction (see, for example, Patent Document 4). According to this technique, the display is arranged on the front side on the user side, and the touch panel is arranged behind the display in the direction of the user side.

  FIG. 1 is a front view of a tablet computer.

  The main body of the tablet computer is made of metal or synthetic resin, and has a size that allows a user to hold it with both hands (of course, one hand may be used). According to FIG. 1, the touch panel display 10 is arranged over the entire surface area of the front surface of the tablet computer. On the touch panel display 10, a plurality of function images such as application activation buttons are displayed. It is like an icon of a user interface in an OS for a personal computer. The user can operate by touching the functional image with a finger.

  In the case of a tablet computer, since the display area for the user is relatively wide, a functional image of a QWERTY keyboard can also be displayed on the touch panel display. The “QWERTY layout” is a key layout as a de facto standard in a keyboard in which Latin characters are engraved. At present, as a keyboard, a full keyboard operated with both hands as the QWERTY layout of a personal computer has become most popular. As a result, this input operation is the most widely used keyboard. The user can input a key by touching a button on the keyboard image with a finger.

  In the case of a tablet computer, the user can perform touch typing in the same manner as a keyboard of a personal computer. Normally, although there are variations among users, for each key of the QWERTY keyboard, the hand and the finger pressing the key are constant. For example, the key [F] is pressed with the index finger of the left hand. The key [K] is pressed with the middle finger of the right hand.

  However, in the case of a touch panel display, since it touches itself with a finger or a pen, a fingerprint mark by the finger or a scratch by the pen also gives an uncomfortable feeling to the user's visibility. In addition, since the touch panel display touches a virtual button displayed on the screen, it does not return a mechanical reaction due to a finger press. For this reason, it is not possible to obtain human natural physical operation feeling. Some devices create a secondary reaction, such as a vibrator, when the virtual button is pressed. However, since the mechanical dedicated parts are mounted, the volume of the apparatus is increased, and the cost and power consumption are also increased.

  In addition, when the key input unit that can be physically pressed is not disposed on the front surface of the information device but is disposed at another position, it is necessary to press the same key with different hands and fingers. In particular, in the case of the QWERTY keyboard, the user feels uncomfortable. In other words, even if the user is accustomed to pressing the key [F] with the index finger of the left hand, it must be pressed with a different hand and finger depending on the arrangement of the keyboard. The user who is used to touch typing has a sense of incongruity in the key input operation and the input speed has to be slow.

It is the 3rd back view of a tablet type computer provided with a touchpad. It is an internal block diagram at the time of providing a touchpad on the back. It is the 4th back view at the time of holding a tablet type computer sideways. It is the external view which displayed the reduced keyboard image on the display.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

  An information device targeted by the present invention includes a display and a key input unit. The display is disposed on a surface that is viewed in the field of view when viewed by the user, for example, the front surface. The key input unit is disposed on a surface that is not viewed in the field of view when the display is viewed by the user, for example, the back surface or the side surface. The key input unit can be physically pressed and is a keyboard or a touch pad. This information device is held by the palm of the user, and a key can be pressed by the finger of the hand. Therefore, although it is preferable that it is a portable type, it may be a user interface device for a stationary information device. In the following description, it is assumed that the information device is a tablet computer.

  FIG. 2 is a first rear view of the tablet computer according to the present invention.

  According to the tablet computer 1 of FIG. 2, the key input unit 11 is disposed on the back surface of the display 10. The key input unit 11 is not viewed in the field of view when the user is viewing the display 10. Of course, the key input unit 11 is not limited to the back surface of the display 10 and may be disposed on the side surface of the information device.

  The plurality of keys of the key input unit 11 are targeted for the QWERTY array. The keys of the key input unit 11 correspond to the keys in the QWERTY layout of the functional image of the keyboard displayed on the display 10 in FIG. This has a “functional position corresponding to the functional image”.

  According to FIG. 2, the QWERTY keyboard is divided into a first key group pressed by the left hand and a second key group pressed by the right hand. In addition, when the user holds the tablet computer 1 with the palm of the hand, the first key group is disposed on the back portion on the left hand side where the finger of the left hand contacts, and the second key group includes the finger of the right hand. It is arranged on the back portion on the right hand side that comes into contact. It should be noted that each of the first key group and the second key group is arranged in a mirror relationship with respect to the QWERTY array.

  Also, according to FIG. 2, track points 12 are also arranged. Usually, the track point is arranged at the center of a QWERTY keyboard. That is, it is arranged between the first key group operated by the left hand and the second key group operated by the right hand. Also, the track point is usually operated with the index finger of the right hand placed at the home position (the key position where the fingers of both hands are always placed).

  On the other hand, according to FIG. 2, since the key input unit 11 is arranged on the back surface, the track point 12 is arranged on the side surface portion on the right hand side. The track point 12 at this position is easy to operate with the index finger of the right hand of the user holding the tablet computer 1. Accordingly, the pointing operation on the application image 100 can be easily performed from the back side.

  According to FIG. 2, the key input unit 11 is touched and pressed by a finger other than the user's thumb (index finger, middle finger, ring finger and / or little finger). Of course, it may be operated by the thumb. Here, the assignment function display need not be printed on the key top of the keyboard 11 provided on the back surface. This is because the user sees only the keyboard image 101 displayed on the display 10 and does not see the keyboard itself arranged on the back. That is, the push-type input unit is disposed on a surface that is not visible in the field of view when the display 10 is viewed by the user.

  FIG. 3 is an external view of the user's input operation as seen from the back in FIG.

  According to FIG. 3, the user can press the key [F] with the index finger of the left hand in the same manner as the touch typing on the QWERTY keyboard. The key [K] can be pressed with the middle finger of the right hand. As a result, a user who is used to touch typing does not feel uncomfortable in the key input operation, and the input speed does not slow down. As described above, according to the present invention, the user inputs the same character with the same hand and finger as when inputting on the existing keyboard.

  FIG. 4 is an external view of the user's input operation as seen from the front in FIG.

  A QWERTY keyboard image is displayed on the display 10. When the user touches any key on the keyboard on the back, the key displayed on the display 10 is visually specified. For example, the contact point 102 is represented by a red circle. Thus, the user can visually know which key the finger is touching.

  When the finger is touching, the key is not pressed. For this reason, the information assigned to the key is not input. Next, the user can input the key assignment information by physically pressing the desired key while looking at the contact point 102 displayed on the display 10.

  Thus, the information obtained from the touch sensor is used exclusively for the purpose of presenting the contact position of the finger to the keyboard to the user. Therefore, a physical keyboard is used for actual key input. Thereby, it becomes possible to give a user a natural physical operation feeling (mechanical reaction in input), and the operability of input can be improved.

  For example, as in Non-Patent Document 2 and Patent Document 3, there is an existing technology that includes a touch panel on the back of a device. According to this technique, the uncomfortable feeling of visibility can be eliminated, but eventually a natural physical operation feeling cannot be obtained. In contrast, in the present invention, a touch of a finger is detected by a touch sensor by combining a touch sensor and a keyboard, and actual key input is operated by a physical keyboard.

  Further, according to FIG. 4, the pointer based on the operation of the track point 12 is also displayed as the pointer image 103 on the application image 100 of the display 10.

  FIG. 5 is an internal configuration diagram when a physical keyboard is provided on the back surface.

  According to FIG. 5, the portable information device 1 includes a key top 111, a press detection unit 112, a touch sensor 113, a protective film 114, and a display control unit 115. Here, the display control unit 115 is realized by executing a program that causes a computer mounted on the portable information device to function.

  The key top 111 is a button (pressing surface) having a convex physical shape arranged for each key. The user's finger applies acupressure to the key top.

  The press detection unit 112 is connected to the key top (press surface) 111 and detects a physical press on each key. The physical press detection unit 112 may be configured integrally with the substrate.

  The touch sensor 113 is provided on the surface of the key top 111, and detects the proximity state of the finger to each key (pressing surface) (see, for example, Non-Patent Documents 1 and 3). The proximity state refers to a state where the finger is touching the key or the finger and the key are separated enough to receive static electricity. In the following description, it is assumed that “finger touch” is a proximity state.

  The touch sensor 113 includes, for example, an electrostatic sensor, a resistive film sensor, or an optical or thermal sensor. A finger touch signal detected by the touch sensor 113 is output to the display control unit 115.

  The protective film 114 protects the touch sensor 113 from the finger and, for example, energizes the touch sensor 113 with static electricity generated by the finger as it is.

  The display control unit 115 displays the function image of each key on the keyboard on the display. At this time, the arrangement of the keyboard arranged on the back is different from the keyboard image displayed on the display. Further, the display control unit 115 specifically displays the key (functional position) touched by the finger on the display based on the signal received from the touch sensor 113. By displaying the visual contact point on the key displayed on the display, the user can recognize the key touched by the finger.

  For example, the key input unit 11 draws lines in the vertical and horizontal directions of the keys on the keyboard, and outputs the intersection information of the pressed key to the display control unit 115. The display control unit 115 has table information that prescribes which key in the QWERTY array corresponds to the intersection information. The key information obtained from the table is output to the application.

  Furthermore, it is preferable that the display control unit 115 changes the function assignment of the keys on the keyboard in accordance with the holding direction detected by the attitude sensor 116. This is because the position of the finger touching the keyboard varies depending on the orientation of the portable information device 1 with respect to the user. For example, the keyboard key function assignment can be changed so that the user can operate with both hands when the holding posture is horizontal and can be operated with one hand when the posture is vertical.

  FIG. 5 also shows a flowchart of an input method for the information device.

(S1) The function image of each position on the pressing surface in the pressing type input unit is displayed on the display.
(S2) The proximity state of the position of the user's finger is detected by a sensor on the surface of the pressing surface.
(S3) On the display, whether or not the user's finger is close to the functional position associated with the functional image is specifically displayed.
(S4) Physical pressing of the pressing surface is detected by finger pressure on the pressing surface.
(S5) The function based on the function image associated with the function position where the user's finger is close is executed.

  FIG. 6 is a second rear view of the tablet computer according to the present invention.

  According to FIG. 6, with respect to the key input unit arranged on the back surface of the display, the first key group is arranged by being rotated 90 degrees clockwise toward the right hand side surface of the information device. However, it is rotated 90 degrees counterclockwise toward the left-hand side of the information device. Thus, when the palm of the user grips the side of the information device, the first key group is in contact with the right finger and the second key group is in contact with the left hand finger. Yes.

  FIG. 7 is an external view of the user's input operation as seen from the back in FIG. FIG. 8 is an external view of the user's input operation as seen from the front in FIG.

  Even if the user grips the tablet computer 1 from the side, each key of the key input unit 11 is arranged at a position that is most easily touched by each finger.

  FIG. 9 is a third rear view of a tablet computer equipped with a touchpad.

  9 is different from FIG. 6 only in that a touch panel 11 is provided on the back of the tablet computer. On the touch panel 11, functional positions are assigned to the respective positions in terms of software. The function position corresponds to the function image displayed on the display 10. The display screen on the display 10 is the same as in FIG.

  FIG. 10 is an internal configuration diagram when a touch pad is provided on the back surface.

  According to FIG. 10, compared with FIG. 5, since a touchpad is provided, a structure is different. According to FIG. 10, the press detection unit 112, the touch pad 113, the protective film 114, the display control unit 115, the posture sensor 116, and the elastic unit 117 are included.

  The elastic part 117 is disposed between the touch pad 113 and the press detection part 112. The elastic portion 117 generates pressure fluctuation due to finger pressure applied to the touch pad. The pressure fluctuation of the elastic part 117 is applied to the entire pressing detection part 112.

  The pressing detection unit 112 is connected to the elastic unit 117 and detects physical pressing of the entire surface of the touch pad 113. Similar to FIG. 5, the physical press detection unit 112 may be configured integrally with the substrate.

  The touch pad 113 includes a sensor on the surface, and detects the proximity state of the finger to the touch pad. The sensor of the touch pad 113 functions in the same manner as the touch sensor 113 of FIG. A finger touch signal detected by the touch pad 113 is output to the display control unit 115. The display control unit 115 configures a functional position on the touch pad in association with the functional image displayed on the display. Here, the sensor of the touch pad 113 configures a functional position of left-right reversal (and rotation) so that each of the first key group and the second key group has a mirror surface relationship.

  The posture sensor 116 is, for example, an acceleration sensor (for example, a semiconductor type), and can detect the vertical direction of the portable information device. The gravitational acceleration of the earth can be measured from the detected values of the three axes, and the inclination of the portable information device can be detected.

  Other components function in the same manner as in FIG.

  FIG. 11 is a fourth back view when the tablet computer is held sideways.

  According to FIG. 11, it is detected by the attitude sensor 116 whether it is held vertically or horizontally. At this time, the display control unit 115 changes the allocation of the function position and the function image according to the direction of gravity detected by the posture sensor 116. It is detected that gravity is directed to any one of the four sides of the tablet computer 1. According to FIG. 11, when it is detected that the hand is held sideways, two sides adjacent to the side on which gravity is directed are held by the user.

  FIG. 12 is an external view of a reduced keyboard image displayed on a display.

  According to FIG. 12, the range of the application image 100 occupied on the display 10 can be made as wide as possible by reducing the keyboard image. Here, as in FIGS. 4 and 8, the contact point is specified and displayed. Even if the position of the keyboard arranged on the back surface and the position of the keyboard image 101 displayed on the display 10 do not necessarily match, the operability from the user is maintained. Such control is executed by the display control unit 115 described above.

  As described above in detail, according to the information device, the input method, and the program of the present invention, the same characters and characters are input by the same hand and finger as those input to the existing keyboard, A natural-physical operation feeling can be obtained. In particular, the user can operate the keyboard with both hands, and can obtain an input operation feeling close to that of a QWERTY keyboard.

  Various changes, modifications, and omissions of the above-described various embodiments of the present invention can be easily made by those skilled in the art. The above description is merely an example, and is not intended to be restrictive. The invention is limited only as defined in the following claims and the equivalents thereto.
