Description

  The present invention includes a light source that emits light to a finger and an image sensor that receives reflected light from the finger in order to move a graphic object that is moved and displayed on the display screen according to the movement of the user's finger. The present invention relates to a graphic object movement input device having an optical pointing device that detects the movement of a finger, and an electronic device equipped with the graphic object movement input device. BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a graphic object movement input device that can be mounted, and an electronic device that mounts the graphic object movement input device.

  Conventionally, a portable information terminal such as a mobile phone has adopted a user interface using a keypad, and such a keypad is composed of a plurality of buttons and direction buttons for inputting numbers and characters. It was.

  In recent years, graphics can be represented on a display unit of a portable information terminal, and the display unit can be used two-dimensionally. As described above, the function of the portable information terminal approaches the function of a computer, and the operation is complicated. In recent years, the method of performing a desired function using a keypad easily performs a complicated operation. Therefore, it is difficult to adopt as an input method for a portable information terminal. For this reason, a pointing device that enables operations such as a mouse and a touch pad used in a computer is desired as an input method for a portable information terminal.

  In addition, various types of portable information terminals have been diversified, and tablet terminals having a large screen capable of displaying more information have also appeared. Advances in definition when displaying on a screen have made it possible to display small characters, symbols, and the like.

  In these portable information terminals having large and high definition screens, when selecting information displayed on this screen and selecting and operating the displayed functions, it is possible to point more widely and There is a need for a pointing input device capable of pointing with high accuracy.

    In recent years, cellular phones, PDAs (Personal Digital Assistants), and portable information terminals such as tablet terminals that use touch panels as input devices have become widespread.

  In the touch panel, when information displayed on the screen is selected, it is selected by touching a finger. However, as characters and symbols displayed by screen display of a portable information terminal become smaller, it becomes very difficult to select desired information when touched with a finger.

  Since the displayed characters and symbols are small, when desired information is selected with a finger, different adjacent information may be erroneously selected. In order to prevent erroneous selection when touching with a finger, a function called zoom that enlarges the screen by expanding an enlargement button or two fingers on the touch panel is provided to prevent erroneous selection. However, the operation of enlarging each time a selection is required is very troublesome.

  As described above, in the touch panel, the operation becomes complicated in order to perform high-precision pointing on a high-definition screen.

  Also, televisions have been equipped not only with conventional broadcast displays but also with a function of displaying a lot of information by connecting to the Internet. In addition, as the screen display of a television becomes larger and higher in definition, characters and symbols displayed on the screen have become smaller.

  Therefore, like a portable information terminal, there is a need for a pointing input device capable of pointing in a wider range on a television and capable of pointing with higher accuracy.

  In such a background, as a pointing input device capable of performing high-precision pointing, a method for extracting a change in a fingertip surface in contact with a display device by observing a pattern such as a fingertip in contact with a display device with an image sensor has been proposed. . Optical that uses a method of illuminating a fingertip surface that is in contact with a light source, forming a pattern on the contact surface on an image sensor with a lens, and detecting the change in the pattern to convert the movement of the fingertip into an input signal A type pointing device has been proposed.

  For example, there is an optical pointing device described in Patent Document 1 as such an optical pointing device.

  This optical pointing device includes a cover glass, a light source unit, and a light receiving unit. The light source unit is divided into a light source and a light source guide including a plurality of reflection mirrors arranged on the light source. The light emitted from the light source is reflected at a predetermined angle by the reflection mirror and is irradiated onto the cover glass. The light irradiated on the cover glass is reflected by the surface of the finger, and the light reflected by the surface of the finger is irradiated on the light receiving unit. The light receiving unit includes a reflection mirror, a condenser lens, and an optical image sensor. The light reflected by the reflection mirror is imaged by the condenser lens and provided to the optical image sensor.

  Further, as a further optical pointing device, there is one described in Patent Document 2.

  The optical pointing device includes a light source that irradiates light to a subject, a cover portion on which a contact surface that contacts the subject is formed, a light receiving portion that detects light reflected by the subject, and light reflected by the subject. It is comprised from the optical member which guides to a light-receiving part.

Special table 2008-507787 (published March 13, 2008) JP 2009-176271 A (released on August 6, 2009) JP 2008-250472 A (released on October 16, 2008)

  As described above, an optical pointing device capable of highly accurate pointing has been proposed. However, since the optical pointing devices disclosed in Patent Documents 1 and 2 are operated with a finger, the moving distance on the screen during a pointing operation that can be operated at a time is limited. For this reason, if you want to move the pointing function greatly on a large screen such as a personal digital assistant or TV, you need to repeat the pointing operation with your finger many times on the optical pointing device. There is a problem that there is.

  In order to reduce the number of pointing operations with a finger on the optical pointing device, the setting of the amount of pointing movement on the screen relative to the movement of the finger in the optical pointing device can be made larger. It becomes possible to move and reduce the number of pointing operations with a finger. However, on the contrary, there is a problem in that it is difficult to perform highly accurate pointing because the amount of movement on the screen in response to the operation of the finger is large.

  As described above, the optical pointing device has a problem in realizing a wide range and highly accurate pointing. This problem is not only the pointing that indicates the position on the display screen such as a cursor, but also a display object that is scrolled on the display screen, such as a map, and a matrix selection that is menu-selected on the display screen. The same applies to graphic objects such as display objects.

  In view of the above, it is an object of the present invention to provide a graphic object movement input device capable of moving a graphic object over a wide range and with high accuracy, and an electronic apparatus equipped with the graphic object movement input device.

  In order to solve the above problems, a graphic object movement input device according to the present invention emits light to a finger in order to move a graphic object that is moved and displayed on a display screen according to the movement of a user's finger.

  With the above configuration, graphic objects can be moved over a wide range and with high accuracy by pressing the button switch, not only in the vertical and horizontal directions but also in the diagonal direction, without having to repeat the pointing operation with the finger using the optical pointing device. Can be made.

  In the graphic object movement input device according to the present invention, it is preferable that the first to fourth switches are arranged so as to surround the optical pointing device.

  With the above configuration, the distance between the optical pointing device and the first to fourth switches is reduced, so that the amount of finger movement from the optical pointing device to the switch can be reduced.

  In the graphic object movement input device according to the present invention, the button switch is provided on a surface opposite to a direction in which light from the light source is applied to the finger with respect to a substrate on which the light source of the optical pointing device is mounted. It is preferable that

  With the above configuration, since the button switch is arranged on the surface opposite to the direction of light irradiation from the light source to the finger on the substrate on which the light source of the optical pointing device is mounted, it is necessary to provide a large button switch The graphic object movement input device can be reduced in size. In addition, since the button switch can be operated without releasing a finger placed on the optical pointing device, it is possible to move the graphic object more intuitively and smoothly.

  In the graphic object movement input device according to the present invention, a fixing plate facing the surface opposite to the irradiation direction of the light from the light source to the finger is further provided on the substrate on which the light source of the optical pointing device is mounted. Preferably, the button switch is provided on a surface of the fixing plate on the optical pointing device side, and a means for pressing the button switch is provided on the opposite surface of the optical pointing device.

  With the above configuration, since the button switch is provided on the surface of the fixed plate on the optical pointing device side, it is not necessary to provide a large size button switch, and the graphic object movement input device can be downsized.

  In the graphic object movement input device according to the present invention, it is preferable that a means for preventing the finger from slipping is provided on the periphery of the operation surface of the optical pointing device by the finger on the irradiation direction side of the light source.

  With the above configuration, since the finger can be operated without slipping when the finger moves, the graphic object can be moved more reliably.

  In the graphic object movement input device according to the present invention, the graphic object is menu-selected on the display screen, pointing indicating the position on the display screen, a display object to be scrolled on the display screen, and the display screen. It is preferable to include at least one of the matrix-shaped selection display objects.

  With the above configuration, a pointing object that indicates a position on the display screen and a display scrolling operation on the display screen can be performed by pressing a button switch without repeating the pointing operation with a finger by the optical pointing device many times.

  Hereinafter, the tablet terminal according to the embodiment of the present invention will be described in detail.

(Embodiment 1)
(Configuration of tablet terminal 15)
FIG. 1 is a block diagram illustrating a configuration of the tablet terminal 15 according to the first embodiment. FIG. 2 is a front view of the tablet terminal 15.

  The tablet terminal 15 includes a display 16 having a display screen 9 for displaying information. The tablet terminal 15 is provided with the graphic object movement input device 1 for moving the cursor 10 indicating the pointing coordinates on the display screen 9 in accordance with the movement of the user's finger 8.

  The graphic object movement input device 1 is provided on the right side of the display screen 9 and includes an optical pointing device 2 that puts a user's finger 8 and detects its movement. A button switch unit 3 is provided on the right side of the display screen 9 and below the optical pointing device 2. The button switch unit 3 includes a switch 7a for largely moving the cursor 10 upward, a switch 7b for largely moving the cursor 10 to the left, and a switch 7c for largely moving the cursor 10 to the right. And a switch 7d for moving the cursor 10 downward largely. The switches 7a to 7d (first switch to fourth switch) are arranged in a line in the vertical direction.

  The graphic object movement input device 1 is provided with a microcomputer 4. The microcomputer 4 takes in the signal output from the optical pointing device 2, processes the signal, and then moves the cursor 10 displayed on the display screen 9. The microcomputer 4 is longer than the moving distance of the cursor 10 on the display screen 9 based on the movement of the finger 8 detected by the optical pointing device 2 in response to the pressing of the switch 7a, 7b, 7c, or 7d. The cursor 10 is moved on the display screen 9 by the distance.

(Operation of Graphic Object Moving Input Device 1)
When the finger 8 is slid on the optical pointing device 2, a displacement amount (ΔX, ΔY) of two-dimensional coordinates corresponding to the movement of the finger 8 is output from the optical pointing device 2. The output of the displacement amount is read into the microcomputer 4 and the coordinates of the cursor 10 and the display of the cursor 10 are updated. Thereby, the position of the cursor 10 can be moved according to the movement of the user's finger 8.

  In addition, by pressing the switches 7a to 7d of the button switch unit 3, the coordinates of the cursor 10 can be moved up, down, left and right. At this time, the moving distance of the cursor 10 by the switches 7a to 7d is sufficiently larger than the moving distance of the cursor 10 by one slide of the finger 8 in the optical pointing device 2 described above (in the present embodiment). (Approximately twice).

  FIG. 3 is a diagram for explaining the operation of the tablet terminal 15. FIG. 4 is a diagram for explaining another operation of the tablet terminal 15.

  FIG. 3 shows an operation when the cursor 10 is moved only by the optical pointing device 2. The distance that can be moved by sliding the finger 8 once in the optical pointing device 2 is a distance corresponding to the radius of the range 17. When the cursor 10 is moved to the position 20 on the right end of the display screen 9, if the amount of movement of the cursor 10 by one slide of the finger 8 is the amount of movement 18 indicated by the arrow, the cursor 10 moves to the vicinity of the position 20. 3 requires four slides of the finger 8 as shown in FIG. Detailed adjustment of the position of the cursor 10 is performed by sliding the finger 8 placed on the optical pointing device 2.

  FIG. 4 shows an operation when the switches 7a to 7d of the button switch 3 according to the present embodiment are used. When the cursor 10 is moved to the position 20, the cursor 10 can be moved in the right direction by pressing the switch 7c for moving in the right direction. Since the movement amount 19 to which the cursor 10 moves by pressing the switch 7c once is set to twice the movement amount 18, the cursor 10 moves to the position 20 by moving the switch 7c twice. it can. The detailed adjustment of the position of the cursor 10 is similarly performed by sliding the finger 8 on the optical pointing device 2.

  As described above, according to the present embodiment, it is not necessary to repeatedly slide the finger on the optical pointing device many times when the pointing is moved greatly, and it can be moved greatly only by pressing the switch.

  In the above-described embodiment, an example in which the cursor on the display screen of the tablet terminal is moved has been described, but the present invention is not limited to this. For example, the present invention can be applied to an operation on a display object that is scrolled on a display screen, such as a map. Further, the present invention can also be applied to the operation of a matrix-like selection display object that is menu-selected on the display screen. The display screen is not limited to the display screen provided on the tablet terminal, but may be a display screen of a computer or a display screen of a television device. The same applies to the embodiments described later.

(Embodiment 2)
FIG. 5 is a diagram showing the arrangement of the optical pointing device 2 and switches 7a to 7d (first switch to fourth switch) provided in the tablet terminal according to the second embodiment. The example of arrangement | positioning of the button switch part 3 which can move to a direction is shown.

  The switch 7a is disposed adjacent to the upper side of the optical pointing device 2, and the switch 7b is disposed adjacent to the left side. The switch 7c is disposed adjacent to the right side of the optical pointing device 2, and the switch 7d is disposed adjacent to the lower side. In this way, the four-way switches 7a to 7d in the upper, lower, left, and right directions are arranged in the four directions so as to be adjacent to and surround the optical pointing device 2. Other configurations are the same as those in the first embodiment.

  In the configuration shown in FIG. 2 described above, when the cursor 10 is to be moved largely from the state where the finger 8 is slid on the optical pointing device 2, the optical pointing device 2 is separated from the button switch unit 3. Therefore, the amount of movement of the finger 8 from the optical pointing device 2 to the button switch unit 3 becomes large, and the operation becomes complicated.

  According to the present configuration shown in FIG. 5, the distance between the optical pointing device 2 and the switches 7a to 7d is shortened, so that the amount of movement of the finger 8 can be reduced, and the cursor 10 is moved up and down in the direction in which it is desired to move. Since the left and right switches 7a to 7d are provided, the button switch unit 3 can be used intuitively and smoothly.

  In the example shown in FIG. 5, four up / down / left / right switches are provided, but eight-way switches (first switch to eighth switch) may be provided by adding diagonal directions to the top / bottom / left / right. As a result, the cursor can be moved not only vertically and horizontally, but also in an oblique direction, so that the cursor can be moved more intuitively and smoothly.

(Embodiment 3)
(Configuration of optical pointing device 2)
FIG. 6 is a cross-sectional view showing the configuration of the optical pointing device 2 and shows the detailed configuration of the optical pointing device 2 described above in the first and second embodiments.

  The optical pointing device 2 includes a substrate 21. A light emitting element 5 as a light source and an image sensor 6 as an imaging element are mounted on the surface of the substrate 21. A lens 22 is provided above the image sensor 6. The substrate 21, the light emitting element 5, the image sensor 6, and the lens 22 are covered with a cover 23.

  The light L emitted from the light emitting element 5 reaches the surface of the cover 23. There is a finger 8 as a subject on the surface of the cover 23, and the light L reflected on the surface is condensed by the lens 22 and forms an image on the image sensor 6. By detecting a change in the formed image, the movement of the finger 8 is converted into an electrical signal.

  An electrode (not shown) for extracting an electrical signal is provided on the back surface of the substrate 21 and is electrically connected to the flexible printed circuit board 24. Two electrodes (not shown) are provided on the back surface of the flexible printed circuit board 24. A sheet switch 27 including a metal dome 25 and a protective sheet 26 is attached to the back surface of the flexible printed board 24.

  The metal dome 25 has a dome shape, and its peripheral portion is in contact with one electrode on the back surface of the flexible printed circuit board 24 and is in an electrically conductive state. The metal dome 25 is not in contact with another electrode and is electrically non-conductive. Below that, there is provided a fixed plate 12 which is a substrate of an electronic device in which the optical pointing device 2 is incorporated. A pusher 13 for pushing the metal dome 25 is provided on the surface of the fixed plate 12 on the optical pointing device 2 side.

(Operation of the optical pointing device 2)
When the finger 8 is slid on the cover 23 of the optical pointing device 2, a displacement amount (ΔX, ΔY) of two-dimensional coordinates corresponding to the movement of the finger 8 is output from the optical pointing device 2. The output of the displacement amount is read into the microcomputer 4 (FIG. 1), and the coordinates of the cursor 10 (FIG. 2) and the display of the cursor 10 are updated. Thereby, the position of the cursor 10 can be moved according to the movement of the user's finger 8.

  In this way, when the menu key and other function keys are selected with the finger 8 and then the optical pointing device 2 is pressed for determination, the sheet switch 27 sandwiched between the flexible printed circuit board 24 and the pusher 13 is pressed. The metal dome 25 is deformed flat and comes into contact with another electrode on the back surface of the flexible printed board 24. Thereby, it will also contact with the electrode which the peripheral part of the metal dome 25 was contacting, and will be in an electrical contact state. The electronic device detects this conduction state and generates a determination signal.

  When the finger 8 stops pressing the optical pointing device 2, the metal dome 25 of the sheet switch 27 returns to a dome shape, and again comes into a non-contact state with the other electrode and returns to a non-conductive state.

  FIG. 7 is a cross-sectional view showing a configuration of an optical pointing device 2a provided in the tablet terminal according to the third embodiment. The same reference numerals are given to the same components as those described above. Detailed description of these components will not be repeated.

  In the third embodiment, a metal dome 28a for determination and a metal dome 28b for pointing movement are arranged instead of the sheet switch 27 for determination in the optical pointing device 2 shown in FIG. .

  A metal dome 28 a is provided on the surface 11 of the flexible printed circuit board 24 opposite to the substrate 21. Four metal domes 28b are provided so as to surround the metal dome 28a in the vertical and horizontal directions of the metal dome 28a (FIG. 7 is a sectional view, so only two are shown). A protective sheet 29 is provided so as to cover the metal dome 28a and the four metal dome 28b.

  Thus, the button switch (the metal dome 28b and the protective sheet 29) has the irradiation direction of the light L from the light emitting element 5 to the finger on the substrate 21 on which the light emitting element 5 of the optical pointing device 2a is mounted. It is provided on the opposite surface 11.

  FIG. 8 is a cross-sectional view showing the operation of the optical pointing device 2a. FIG. 8 is a cross-sectional view of the optical pointing device 2a in a state where the sheet switch is operated for the pointing movement.

  When a large pointing movement is performed from the state where the optical pointing device 2a is used, the sheet switch (metal dome 28b) can be operated by tilting the pointing device 2a. For this reason, it becomes possible to make a large pointing movement by pressing the button switch without releasing the finger from the surface of the optical pointing device.

  Thus, since the button switch (metal dome 28b) is disposed on the back surface of the optical pointing device 2a, it is not necessary to provide a large size button switch. This is advantageous for miniaturization of the optical pointing input device 2a.

  Further, since the button switch can be operated without releasing the finger placed on the optical pointing device 2a, the pointing movement can be performed more intuitively and smoothly.

(Embodiment 4)
(Configuration and operation of optical pointing device 2b)
FIG. 9 is a cross-sectional view illustrating a configuration of an optical pointing device 2b provided in the tablet terminal according to the fourth embodiment. The same reference numerals are given to the same components as those described above. Detailed description of these components will not be repeated.

  In the optical pointing device 2b, a button switch (sheet switch (metal dome 28b)) is provided on the fixed plate 12 for pointing movement, and the back of the flexible printed circuit board 24 of the optical pointing device 2b is pressed to press the button switch. A child 13 is provided. Four metal domes 28b are provided so as to surround the vertical and horizontal directions of the pusher 13 provided on the fixed plate 12, and a protective sheet 30b is provided so as to cover each metal dome 28b.

  In this way, the fixing plate 12 facing the surface opposite to the irradiation direction of the light L from the light emitting element 5 to the finger is provided on the substrate 21 on which the light emitting element 5 of the optical pointing device 2b is mounted. The button switch (metal dome 28b, protective sheet 30b) is provided on the surface of the fixed plate 12 on the optical pointing device 2b side, and the button switch (metal dome 28b, protective sheet) is provided on the opposite surface of the optical pointing device 2b. A pusher 13 is provided for pushing the sheet 30b).

  In order to operate this button switch, the optical pointing device 2b may be tilted as described above with reference to FIG.

  In the fourth embodiment, since a button switch (sheet switch) is provided on the fixed plate 12 for pointing movement, only the pusher 13 is provided on the back surface of the flexible printed circuit board 24 of the optical pointing device 2b. The same operation as shown is possible. This makes it possible to reduce the size of the optical pointing device, which is advantageous for downsizing the optical pointing device.

  In recent portable information terminals such as tablet terminals, the area of the peripheral portion (frame portion) of the screen tends to be reduced as the screen is enlarged, and there is a demand for downsizing peripheral devices. The size reduction of the pointing input device shown in this embodiment is very advantageous from the above viewpoint.

  In addition, an example in which a pointing function is provided in a remote controller for selecting information on a television is also seen. In remote control terminals for televisions, the number of buttons is increasing due to the increase in functions. When the pointing input device according to the embodiment is mounted on a remote control terminal, the number of buttons on the remote control terminal can be reduced, and it is advantageous for reducing the size of the remote control terminal.

As described above, the optical pointing device 2c for pointing movement is tilted to operate the button switch (sheet switch), but when tilted, the finger 8 may slide on the upper surface of the cover 23 of the optical pointing device 2c. . When the finger 8 slips, the optical pointing device 2c detects the movement of the finger 8, and the pointing (coordinates) may be shifted. In order to prevent the above-mentioned slip, a protrusion 14 is provided on the periphery of the upper surface of the cover 23 of the optical pointing device 2c.

  As described above, the protrusion 14 that prevents the finger from slipping is provided on the periphery of the operation surface of the cover 23 of the optical pointing device 2c by the finger on the irradiation direction side of the light emitting element 5.

(Effect of the optical pointing device 2c)
