Description

  The present invention relates to an electronic apparatus having an information output unit that outputs input data corresponding to a contact position when a finger touches the information input unit, and more particularly to a technique for performing enlarged display of information input means in the information input unit. .

  In recent years, in-vehicle electronic devices in which functions such as car navigation, a television device, and an audio device are integrated are known. Such an electronic device is mainly used by being mounted on an instrument panel in a vehicle, but in recent years, it is a PND (Personal Navigation Device) type electronic device that can be removed from the instrument panel and carried by a user and used outside the vehicle. Is also spreading.

  Such electronic devices tend to be miniaturized (for example, about 200 mm in width, 15 mm in height, and 10 mm in depth) because they are mounted or carried in a limited space of an instrument panel in a vehicle interior. On the other hand, a display screen for displaying a television image or a map image needs a certain size (for example, 4 to 5 inches) for easy viewing of the image or image. Therefore, the proportion of the display screen in the small-sized electronic device as described above increases. Then, the space for arranging various operation buttons corresponding to the multi-function is pressed, and it becomes difficult to arrange the operation buttons.

  Therefore, in such an electronic device, a touch panel type input interface is used in order to ensure the area of the display screen and the space for arranging the operation buttons at the same time. That is, a touch panel composed of a transparent pressure detection device is provided on the display screen, and information input means (for example, a character key or an icon image) is displayed on the display screen. When the user touches the display location of the information input means selected by the user with a finger, the touch panel outputs the input data displayed at the contact position, and this input data performs a route search to the destination and a search for video and music. To the information processing unit.

  Even when such a touch panel type input interface is used, the amount of information input means that can be displayed on a display screen with a limited area is naturally limited. Then, if a large amount of information input means is displayed at a time, the display of each information input means becomes small, which causes inconvenience for the user to touch with fingers. For example, when displaying a character key for selecting and inputting a character or an icon image for selecting and inputting a destination on a map, if the display area of an individual key or icon image is small, the user may select an incorrect key or There is a risk of erroneous input by touching the icon image.

Therefore, various methods for assisting input have been proposed to deal with such problems. As one of the methods, when a user selects an information input means, a method for preventing an erroneous input is proposed by temporarily displaying the information input means so that the user can confirm the information input means to be selected. For example, Patent Documents 1 and 2 describe a method for enlarging and displaying information input means such as a character key or a character string touched by a user.
JP 2000-284774 A JP 2004-355336 A

  However, in the above method, if the user makes a mistake in the initial contact position, the target information input means is not enlarged and displayed. Then, the user again needs to perform an operation for enlarging and displaying the information input means. Therefore, the operation until the target information input means is enlarged and displayed and checked and selected becomes complicated.

  SUMMARY OF THE INVENTION An object of the present invention is to provide an electronic device that can select and input information input means with a simpler operation and prevent erroneous input.

  According to the first aspect of the present invention, the electronic device detects an approach position of the finger to the information input unit when the finger approaches within a predetermined distance from the information input unit and the information input unit. A finger detection unit; a display control unit for enlarging and displaying the information input unit of the information input unit at the approach position when the approach position is detected; and the information input unit in a state where the information input unit is displayed in an enlarged manner. And an information output unit that outputs input data corresponding to the contact position when the finger touches the unit.

  According to a preferred aspect of the above aspect, the display control unit changes an enlargement ratio of the information input unit according to a distance between a finger and a display screen.

  According to another preferable aspect of the above aspect, the display control unit enlarges and displays the information input means displayed in the movement direction when the movement direction of the finger is detected.

  According to another preferable aspect of the above aspect, the display control unit changes the display state of the information input unit when the information input unit corresponding to the input candidate is included in the information input unit at the approach position. It is characterized by.

  The electronic apparatus according to the present invention can select and input information input means with a simpler operation and can prevent erroneous input.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. However, the technical scope of the present invention is not limited to these embodiments, but extends to the matters described in the claims and equivalents thereof.

  FIG. 1 is a diagram illustrating an appearance of an electronic device according to the present embodiment. The electronic device 10 has functions as a car navigation system, a television device, and an audio device as an example, and is used by being mounted on an instrument panel in a vehicle interior or used outside a vehicle by being carried by a user.

Here, a character key is shown as the information input unit, but the information input unit includes a character string, a symbol, or an image such as an operation button or an icon. The display screen 12 is composed of, for example, a liquid crystal display panel or an organic EL panel. On the display screen 12, a touch panel 14 configured by a transparent pressure detection device that detects pressure caused by contact of a user's finger is provided. The display screen 12 and the touch panel 14 constitute the information input unit 11. An electronic circuit for realizing various functions of the electronic device 10 is stored in the main body of the electronic device 10.

  FIG. 2 is a schematic configuration diagram of the electronic device 10 according to the present embodiment. The electronic device 10 includes the information input unit 11 including the display screen 12 and the touch panel 14 as described above. The electronic device 10 includes a display control unit 18 that controls display output of the display screen 12 and an information output unit 16 that detects a contact position on the touch panel 14. When the user's finger touches the information input unit 11, the information output unit 16 acquires input data corresponding to the information input means displayed at the contact position from the display control unit 18, and an information processing unit described later Output to. For example, a destination selection input when the electronic device 10 is used as a car navigation, a channel or video data selection input when used as a television device, or a song data selection input when used as an audio device is information. This is performed from the input unit 11 and the information output unit 16.

  The electronic device 10 also includes an “information processing unit” that executes various information processing based on input data from the information output unit 16. Here, the navigation control unit 20 and the AV (audio / visual) control unit 22 correspond to an information processing unit.

  The navigation control unit 20 receives destination data selected and input by the user, current position data acquired by a GPS (Global Positioning System) receiver 28, and map data stored in advance in the storage device 30. The navigation control unit 20 executes a route search process from the current location to the destination based on the map data in accordance with a processing program stored in advance in an internal or external memory. Then, the search result is displayed on the display screen 12 via the display control unit 18.

  The AV control unit 22 receives input data such as a channel selected by the user and a video name. Then, the television receiver 36 is instructed to receive the input channel, or a list of video data stored in the storage device 30 is acquired from the storage device 30, and the location of the video data selected by the user from the list is determined. Search for. Then, the retrieved video data is read from the storage device 30, and the video signal and its synchronization signal are output to the display control unit 18 and the audio signal is output to the audio output unit 34. Then, the display control unit 18 outputs the video to the display screen 12 based on the video signal and the synchronization signal. The audio output unit 34 outputs audio based on the audio signal.

  Alternatively, the AV control unit 22 receives input data such as a song name selected and input by the user. Then, a list of music data stored in the storage device 30 is acquired from the storage device 30, and the location of the music data selected by the user is searched from the list. Then, the retrieved music data is read from the storage device 30 and output to the audio output unit 34, and the audio output unit 34 outputs the audio of the music.

  The storage device 30 is configured by a storage medium such as a hard disk, a DVD, or a nonvolatile memory.

  In addition, the electronic device 10 includes a finger detection unit 26 that detects an approach position of the finger approaching the information input unit 11 in the information input unit 11. The finger detection unit 26 detects the position of the finger on the information input unit 11 based on the detection result of the finger detection sensor 24 configured by an infrared sensor, an electrostatic sensor, a small radar, or the like. More preferably, the finger detection unit 26 detects the distance of the finger from the information input unit 11.

  When an infrared sensor that detects infrared rays emitted by the user's fingers is used as the finger detection sensor 24, a plurality of infrared sensors are arranged around the display screen 12 (for example, at the four corners of the display screen 12). When the detection result of the infrared sensor is input to the finger detection unit 26, the finger detection unit 26 detects the approach position of the finger in the information input unit 11 based on the position of the infrared sensor that has detected the finger. In this case, the distance from the information input unit 11 to the finger is detected to be within a distance range in which the infrared sensor can detect the finger.

  Moreover, you may use the electrostatic sensor which detects the change of an electrostatic capacitance when it couple | bonds with the finger which approaches instead of an infrared sensor as the finger detection sensor 24. FIG. In this case, the finger detection unit 26 detects the approach position of the finger based on the position of the electrostatic sensor that has detected the finger. Further, the distance from the information input unit 11 to the finger detects that the electrostatic sensor is within a distance within which the finger can be detected.

  Further, when a small radar device is used as the finger detection sensor 24, radar transmission / reception antennas are arranged at three points that are not on the same straight line around the display screen 12. Then, for example, the radar transmission / reception antenna transmits a pulse wave and receives reflection by a finger. And the finger detection part 26 calculates | requires the distance from three points to fingers from the round-trip time of a pulse wave. Here, since the three points are not on the same straight line, the approach position of the finger in the information input unit 11 and the distance from the information input unit 11 are detected from the three measurement distances.

  In the above configuration, the display control unit 18, the touch panel control unit 16, the navigation control unit 20, the AV control unit 22, and the finger detection unit 26 are arithmetic processing devices such as a special purpose integrated circuit or a DSP (Digital Signal Processor). Or a microcomputer. Each unit is configured to be able to obtain power from the built-in battery of the electronic device 10.

  In the electronic device 10 configured as described above, the approach position of the finger detected by the finger detection unit 26 and its movement, or the distance from the information input unit 11 is input to the display control unit 18. When the distance of the finger from the information input unit 11 and the approach position on the information input unit 11 are detected, the display control unit 18 causes the information input unit 11 to display an enlarged information input unit at the approach position. By doing so, the user can enlarge and display the information input means by an easy operation of simply bringing a finger close to the information input unit 11, and after confirming this, the user can select by touching on the information input unit 11 You can enter. Therefore, selection input of the information input means can be performed with easier operation, and erroneous input can be prevented.

  Next, a detailed procedure of the electronic device 10 will be described.

[First embodiment]
As a first embodiment, an operation procedure for enlarging display when the distance between fingers is within a predetermined distance will be described. Here, the predetermined distance range is arbitrarily set based on the distance that the finger detection sensor 24 can detect the finger. Here, as an example of destination input when the electronic device 30 is used for car navigation, a case where the information input unit 11 displays a character key as information input means is shown.

  FIG. 3 is a flowchart for explaining the operation procedure of the electronic apparatus 10 in the first embodiment. FIG. 4 is a screen transition diagram showing transition of the information input means displayed by the information input unit 11. The operation procedure will be described according to FIG. 3 with reference to FIG.

  The procedure in FIG. 3 is executed every time one character is selected and input. First, the display control unit 18 performs initial display of character keys (S2). FIG. 4A shows an example of initial display. Character keys as display information that can be selectively input are displayed in the lower part of the information input unit 11, and characters that have been selected and input are displayed in the upper part of the information input unit 11.

  Here, for example, when the user presses the character key “K”, the user brings his / her finger close to the character key “K”. Then, the finger detection unit 26 detects the approach of the finger (S4). When the finger is detected, the distance between the information input unit 11 and the finger is within a predetermined detectable range (YES in S6). Therefore, the approach position of the finger on the information input unit 11 is detected (S8). Here, it is detected that the finger is near the character key “K”.

  The display control unit 18 enlarges and displays the vicinity of the approach position of the finger (S10). FIG. 4B shows a state in which the vicinity of the approach position is enlarged and displayed. Here, since the character keys near the character key “K” including the character key “K” are displayed in an enlarged manner, the user can easily confirm the position of the character key “K” and can touch it without making an error. it can.

  When the information output unit 16 detects a finger contact (YES in S12), the information output unit 16 acquires display information corresponding to the contact position in the information input unit 11, that is, the letter “K” from the display control unit 18, and responds to this. The input data is output to the information processing unit (S14). At this time, the selected input data is sent from the information output unit 16 to the display control unit 18 and displayed as a selected character. Then, the enlarged display ends (S16). Therefore, the display returns to the initial display as shown in FIG. Further, a procedure for returning to the initial display may be executed when the distance between the information input unit 11 and the finger is out of a predetermined distance range that can be detected.

  Note that image data for initial display and enlarged display is stored in the internal memory of the display control unit 18. Alternatively, the display control unit 18 may acquire image data stored in the internal memory of the navigation control unit 20 or the AV control unit 22.

[Second Embodiment]
Next, a case where the display control unit 18 changes the enlargement ratio of the information input unit according to the distance between the finger and the information input unit 11 will be described. According to the configuration using a small radar as the finger detection sensor 24, the distance of the finger from the information input unit 11 can be detected.

  FIG. 5 is a flowchart for explaining the operation procedure of the electronic apparatus 10 in the second embodiment. FIG. 5 corresponds to a modification of the flowchart of FIG. FIG. 6 is a screen transition diagram showing transition of the information input means displayed on the information input unit 11. The operation procedure will be described according to FIG. 5 with reference to FIG.

  First, the display control unit 18 performs initial display of character keys as shown in FIG. 6A (S2). Here, for example, when the user presses the character key “K”, the user brings his / her finger close to the character key “K”. Then, the finger detection unit 26 detects the approach of the finger (S4). When a finger is detected, the distance between the information input unit 11 and the finger is within a predetermined detectable range (YES in S6), the process proceeds to step S7.

  In the second embodiment, the finger detection unit 26 detects the distance from the information input unit 11 to the finger (S7). Then, the approach position of the finger on the information input unit 11 is detected (S8). Here, it is detected that the finger is near the character key “K”.

  Then, the display control unit 18 calculates an enlargement ratio corresponding to the finger distance (S9). Here, a larger enlargement ratio is calculated as the distance is smaller. When calculating the enlargement ratio, calculation processing may be performed based on a predetermined relational expression, or map data in which the distance and the enlargement ratio are associated is stored in a memory in advance, and the enlargement ratio is calculated using this. It may be derived. Then, the display control unit 18 enlarges and displays the vicinity of the approach position based on the derived enlargement ratio (S10). FIG. 6B shows a state in which the vicinity of the approach position is enlarged and displayed. Here, the character keys near the character key “K” including the character key “K” are enlarged and displayed.

  Then, when the information output unit 16 does not detect a finger contact (NO in S12), when a predetermined time (which can be arbitrarily set as an operation cycle) has elapsed and the finger has further approached, steps S4 to S10 are executed. . Then, the character key is enlarged and displayed at an enlargement rate corresponding to the distance of the fingers. FIG. 6C shows a state in which the vicinity of the approach position is enlarged and displayed at a larger enlargement ratio. As described above, since the character keys near the character key “K” including the character key “K” are further enlarged and displayed, the user can easily check the position of the character key “K” and touch the character key “K”. it can.

  When the information output unit 16 detects a finger contact (YES in S12), the information output unit 16 acquires display information corresponding to the contact position in the information input unit 11, that is, the letter “K” from the display control unit 18, Corresponding input data is output to the information processing section (S14). At this time, the selected input data is sent from the information output unit 16 to the display control unit 18 and displayed as a selected character. When the enlarged display ends (S16), the display returns to the initial display as shown in FIG.

  In the above description, the case of a two-stage enlargement ratio is taken as an example, but it can be further divided into a plurality of stages. As the number of stages increases, seamless enlargement display becomes possible. As described above, the larger the magnification rate, the closer the finger is approached, so that the target key is not temporarily lost when the enlarged display is performed. That is, since the user can recognize the target key without feeling confused, the convenience can be improved. And it can touch the target character key without mistake.

[Third embodiment]
Next, a modified example in which the display control unit 18 changes the information input unit that is enlarged and displayed according to the moving direction of the finger will be described.

  FIG. 7 is a flowchart for explaining the operation procedure of the electronic apparatus 10 in the third embodiment. FIG. 7 corresponds to a modification of the flowchart in FIG. FIG. 8 is a screen transition diagram showing transition of information input means displayed on the information input unit 11. With reference to FIG. 8, the operation procedure will be described according to FIG.

  First, the display control unit 18 performs initial display of character keys as shown in FIG. 8A (S2). For example, when the user presses the letter key “M”, the user brings his / her finger close to the letter key “M”. Here, when the user's finger approaches the vicinity of "K" instead of the character key "M", the finger detection unit 26 detects the approach of the finger (S4). When the finger is detected, the distance between the information input unit 11 and the finger is within a detectable distance range (YES in S6), so the distance of the finger from the information input unit 11 is detected (S7), and the information input The approach position of the finger on the unit 11 is detected (S8). Then, it is detected that the finger is near the character key “K”.

  In the third embodiment, the display control unit 18 confirms that the approach position of the finger has moved (S8a). First, when the movement is not confirmed (NO in S8a), an enlargement ratio corresponding to the finger distance is calculated (S9), and the vicinity of the approach position is enlarged based on the derived enlargement ratio as shown in FIG. 8B. Display (S10). Therefore, the vicinity of the character key “K” is first enlarged and displayed.

  If no finger contact is detected (NO in S12), steps S4 to S8a are repeatedly executed. Here, as shown in FIG. 8C, when the finger moves to the right toward the target character key “M”, the movement of the approach position is confirmed (YES in S8a). Then, the display control unit 18 detects the approach position again (S8b). Then, an enlargement factor corresponding to the finger distance is calculated (S9), and the vicinity of the approach position is enlarged and displayed based on the derived enlargement factor (S10). Therefore, the display screen is scrolled to the left as a whole, and the vicinity of the character key “M” is enlarged and displayed.

  Then, when the predetermined time elapses without the information output unit 16 detecting the finger contact (NO in S12), and steps S4 to S10 are executed when the finger approaches. Then, the character key is enlarged and displayed at an enlargement rate corresponding to the distance of the fingers. FIG. 8D shows a state in which the vicinity of the approach position detected again is enlarged and displayed. Here, since the character key near the character key “M” including the character key “M” is further enlarged and displayed, the user can easily confirm the position of the character key “M” and touch it without error. be able to.

  When the information output unit 16 detects a finger contact (YES in S12), the information output unit 16 acquires display information corresponding to the contact position in the information input unit 11, that is, the letter “M” from the display control unit 18, Corresponding input data is output to the information processing section (S14). At this time, the selected input data is sent from the information output unit 16 to the display control unit 18 and displayed as a selected character. When the enlarged display ends (S16), the display returns to the initial display.

  In this way, when the finger approaches, the information input means is enlarged and displayed at a certain magnification, and when the finger is moved toward the target information input means, the information input means displayed in the moving direction is changed to the information input unit. 11 is displayed in the center. According to such a procedure, since the target key is displayed at a position where it can be easily pressed, the user can easily confirm the target key. Therefore, since the target key can be easily recognized, convenience can be improved.

[Fourth embodiment]
In the above, the case where a character key is displayed as an information input means was shown. Next, a case where an image is displayed as information input means will be described. In the following example, when using car navigation, a map image and a destination icon displayed thereon correspond to the information input means.

  FIG. 9 is a screen transition diagram showing transition of information input means displayed on the information input unit 11. The operation procedure of the electronic device 10 is the same as the operation procedure shown in the first to third embodiments.

  FIG. 9A shows an initial display state of the map image and the destination icon. FIG. 9B shows a display state when a finger approaches, and FIG. 9C shows a display state when a finger further approaches. In this way, in the initial display state, in the area where the destinations are dense such as urban areas, the destination icons are close to each other and difficult to touch, but the map image and the destination icon at the approach position are enlarged according to the approach of the fingers. Thus, the destination icons are arranged at appropriate intervals in the enlarged display area. Therefore, the user can easily confirm and touch the target icon. Then, the destination data corresponding to the contact position is output from the information output unit 16 to the navigation control unit 20.

  Note that image data for initial display and enlarged display is stored in the internal memory of the display control unit 18. Alternatively, the display control unit 18 may acquire image data stored in the internal memory of the navigation control unit 20 or the storage device 30.

[Fifth embodiment]
As a modification of the first to third embodiments described above, a case will be described in which information that can be input is displayed so as to be more easily selected from the information input means displayed in an enlarged manner.

  FIG. 10 is a flowchart for explaining the operation procedure of the electronic apparatus 10 in the fifth embodiment. FIG. 10 corresponds to the subroutine of step S10 in the flowcharts of FIGS. FIG. 11 is a diagram for explaining a display example of the information input unit 11 (FIG. 11A) and input candidate data. The operation procedure will be described according to FIG. 10 with reference to FIG.

  First, the display control unit 18 enlarges and displays the character keys near the approach position of the finger (S101). Here, as shown in FIG. 11A, a case where the next character “C” is input while the characters “A” and “B” have been input will be described. In the fifth embodiment, the input candidate data DB as shown in FIG. 11B is stored in advance in the internal memory of the display control unit 18 or the storage device 30. Here, the input candidate data DB has input candidates of destinations “ABC Building”, “AC Department Store”, and “BA Hotel” as input candidates.

  First, the display control unit 18 searches the input candidate data DB for input candidates that match the character string “AB” including the displayed characters “A” and “B” (S102). Then, a matching character string “ABC building” is searched (YES in S104).

  Next, when the display control unit 18 is selected as the next character of the character string “AB”, the character “C” that forms the character string “ABC” that matches the input candidate “ABC building” in front of the finger It is confirmed that it is included in the character key displayed at the approach position (YES in S106). Then, the display state is changed so that the user can easily select the character key “C” (S108). Here, an example in which the character key “C” is displayed larger than the other character keys is shown. In this way, efficient user input can be supported. When the input character string is invalid, it is not necessary for the user to input again, and convenience is improved.

  In addition to the above, the display state can be controlled such that non-selectable character keys are not displayed or the information output unit cannot be selected. Furthermore, when there are a plurality of characters that match forward, it is possible to display the characters in the same size. Alternatively, the past input history may be stored in the memory of the display control unit 18, and the character display state may be differentiated according to the input frequency. For example, it is possible to display a character with a higher input frequency in a larger size and display a lower character in a smaller size.

  In the above description, the destination input when using the car navigation has been described as an example. However, the channel and video name selection input when using the television function and the song name selection input when using the audio function are described. In addition, the above-described procedure can be applied. Furthermore, in addition to the character keys and icon images described above as information input means, the above procedure can also be applied when images such as character strings, various symbols, or operation buttons are used.

  Further, in the above description, an in-vehicle electronic device in which functions such as car navigation, a television receiver, and audio are integrated is taken as an example, but a portable television or audio player having these functions separately, or The present embodiment can also be applied to an electronic device having an information processing function such as a PDA (Personal Digital Assistance).

  As described above, according to this embodiment, an electronic apparatus that can select and input information input means with a simpler operation and can prevent erroneous input is provided.
