Description

  The present invention includes a three-dimensional display function and a three-dimensional input detection function, and during display of an object for input, the display contents of the object are sequentially changed in accordance with an input operation by the user at a stage before input is confirmed. Thus, the present invention relates to a three-dimensional input display device capable of presenting an input operation expected to be performed to a user in real time.

  In recent years, 3D display devices using binocular parallax have been developed. By using this three-dimensional display device, the user can stereoscopically display the displayed image or video by displaying an image corresponding to each of the left and right eyes, for example, with a lenticular lens, a shutter, or the like.

  With the development of such a three-dimensional display device, a three-dimensional input method using a pen-type input device (see Patent Document 1) has been developed in electronic devices. This pen-type input device generates electromagnetic waves in a conical shape, for example, detects its intensity with a detector installed on the display surface of the display, and detects the input point position in three dimensions. When such an input device is used, a user operation can be detected in a three-dimensional space obtained by adding a height direction to conventional two-dimensional coordinates.

  In addition, a two-dimensional flat input device such as a touch panel that has been conventionally used generally detects contact with a user's finger or the like and operates as a trigger. However, a portable information processing terminal such as a cellular phone has a small screen and cannot display an object to be operated large, or a part of the screen is covered with a finger or the like so that the object is difficult to see. Misoperations were easy to occur.

  Therefore, the flat input device is configured so that the user himself / herself cannot recognize whether or not optimum data is being input while the user is inputting by touch control input, and can be recognized after the input is confirmed. However, there has been a drawback of inducing erroneous input, but an information input method using touch control has been proposed that solves the disadvantage without reducing convenience (see Patent Document 2). This information input method is an information input method in which an object pointed to by a user is selected as an input object from among a plurality of objects displayed on a three-dimensional display device, and the depth position of the displayed object or the shape in the depth direction is changed. And a second process of selecting a corresponding object as an input object when the user continues an operation pointing to the object for a predetermined time in the first process.

  Conventionally, as a display device, a two-dimensional flat display is the mainstream, and even when a three-dimensional input device is used, a display for input is projected on a flat surface with respect to the display. There was a mismatch in input capabilities. Even in the information input method of Patent Document 2, the display layer and the operation layer of the display do not match, and thus it is not possible to give the user a sense of unity between the input target and the display image. Moreover, although the operation example by a three-dimensional input device is shown in patent document 1, the input device and the display space are not the same, and an intuitive operation method cannot be provided to the user.

  On the other hand, by using a 3D input device having a 3D display function, it is possible to detect a user's input operation using a 3D space. It can be displayed with a much larger size. In addition, since an operation for user input can be detected even when the finger or the like is not in contact with the display surface or the detector surface (detection position in the two-dimensional input device), The point position can be highlighted in advance based on the action.

  The present invention has been made in view of the above-described problems, and makes it possible for a user to perform an input by performing an operation such that the user directly touches an object displayed three-dimensionally. An object of the present invention is to provide a three-dimensional input display device that can provide a typical input environment and prevent erroneous input.

  In order to solve the above problems, a three-dimensional input display device according to the present invention includes a display unit that displays an object three-dimensionally at a predetermined height, a detection unit that detects a three-dimensional position of an input medium, and the detection unit. When the detected three-dimensional position is within the display area of the object displayed by the display means, the display control means for changing the height of the object based on the three-dimensional position, and the detection means If the displayed three-dimensional position is within the display area of the object displayed by the display means and the distance from the three-dimensional position detected by the detection means to the display means is a predetermined distance, An input means for inputting the associated data is provided.

  According to the three-dimensional input display device according to the present invention, it is possible to perform an input by performing an operation such that the user directly touches an object displayed in three dimensions, thereby enabling an intuitive input to the user. It is possible to provide an environment and prevent erroneous input.

  An embodiment of a three-dimensional input display device according to the present invention will be described with reference to the accompanying drawings. As an example of the three-dimensional input display device according to the present invention, a mobile phone 1 including a three-dimensional display device that allows a user to easily input data by touching a three-dimensionally displayed object with a finger U or the like is given as an example. I will explain.

  FIG. 1 is a perspective view showing a mobile phone 1. As shown in FIG. 1, the mobile phone 1 includes a rectangular plate-shaped housing 10. On one surface of the housing 10, three-dimensional data is displayed in a three-dimensional manner and data is input by detecting the position of the input medium, a speaker 12 that outputs sound, a microphone 13 that inputs sound, and data. An operation key 14 for inputting is provided.

  The three-dimensional display device 11 has a display function for three-dimensionally displaying three-dimensional data, and an input function for inputting data by detecting the three-dimensional position when the user holds an input medium such as a finger or a dedicated pen. It has both functions. The 3D display device 11 performs 3D display using the parallax of the user, for example, by separately displaying display data for the right eye and display data for the left eye. Note that the three-dimensional display method is not limited to this, and any method may be used.

  The three-dimensional display device 11 includes, for example, an infrared transmitter that transmits infrared rays and an infrared detector that detects reflected light from the input medium of the transmitted infrared rays. The mobile phone 1 performs various processes based on the three-dimensional position of the input medium estimated from the reflected light detected by the infrared detector. Note that the three-dimensional position detection method is not limited to this, and any method may be used.

  The operation key 14 may be a key for inputting data by being physically pressed by a user, or a key for inputting data by detecting contact by static electricity or pressure. The operation key 14 is, for example, a power key for switching power ON / OFF or returning from a standby state.

  FIG. 2 is a block diagram showing functions of the mobile phone 1. As shown in FIG. 2, the mobile phone 1 includes a main control unit 20, a power supply circuit unit 21, a three-dimensional input detection unit 22, a three-dimensional display control unit 23, a voice control unit 24, a communication control unit 25, and a storage unit 26. They are configured to be communicable with each other via a bus.

  The main control unit 20 includes a CPU (Central Processing Unit), performs overall control of the mobile phone 1, and performs input control processing, which will be described later, and various other arithmetic processing and control processing. Further, when detecting an input operation of any one of the operation keys 14, the main control unit 20 performs a process corresponding to the operation key 14. The power supply circuit unit 21 includes a power supply source (battery or the like), for example, switches the power supply ON / OFF state of the mobile phone 1 based on an input via a predetermined operation key 14, and power is supplied when the power supply is ON. Electric power is supplied from the supply source to each unit to enable the mobile phone 1 to operate.

  For example, the three-dimensional input detection unit 22 causes the infrared detector of the three-dimensional display device 11 to detect the reflected infrared light transmitted by the infrared transmission device based on a user operation or at regular time intervals. A signal indicating the detected value is generated and transmitted to the main control unit 20. The main control unit 20 that has received the signal estimates a three-dimensional position of the input medium based on this signal, and performs processing corresponding to this position. Based on the control of the main control unit 20, the 3D display control unit 23 generates 3D data for screen display and causes the 3D display device 11 to display the 3D data.

  The sound control unit 24 generates an analog sound signal from the sound collected by the microphone 13 based on the control of the main control unit 20, and converts the analog sound signal into a digital sound signal. Further, when acquiring the digital audio signal, the audio control unit 24 converts the digital audio signal into an analog audio signal based on the control of the main control unit 20, and outputs the analog audio signal as audio from the speaker 12.

  The communication control unit 25 includes an antenna 25a, and based on the control of the main control unit 20, the received signal received from the base station via the antenna 25a is subjected to spectrum despreading processing to restore data. This data is transmitted to the voice control unit 24 and output from the speaker 12 or recorded in the storage unit 26 according to an instruction from the main control unit 20. In addition, when the communication control unit 25 acquires sound data collected by the microphone 13 or data stored in the storage unit 26 based on the control of the main control unit 20, the communication control unit 25 performs a spread spectrum process on these data. And transmit to the base station via the antenna 25a.

  The storage unit 26 is used when processing performed by the main control unit 20 is performed by a ROM (Read Only Memory), a hard disk, a non-volatile memory, and the main control unit 20 that store processing programs and data necessary for the processing. RAM (Random Access Memory) that temporarily stores data to be stored. Further, it is assumed that a processing program when the main control unit 20 performs input control processing described later is stored in, for example, a ROM.

  The storage unit 26 stores button display information 30 defined for a three-dimensional button for a user to perform an input operation. FIG. 3 is a data configuration diagram illustrating an example of the button display information 30. As shown in FIG. 3, button display information 30 includes button ID information 31 for identifying a button, area information 32 indicating a display area of the button on the xy plane, and z indicating the height direction of the button. The height information 33 indicating the display area on the axis and the input operation determination height information 34 indicating the height for determining the input operation at the button are associated with each other. In the display area on the xy plane of one of the buttons, when an input on the plane of the height indicated by the input operation determination height information 34 (input determination surface 42) is detected, the input operation is determined It is determined that the input process is executed.

  According to the button display information 30 shown in FIG. 3, for the button ID “01”, “(2, 2), (2, 4), (4, 2), (4, 4)” is displayed on the xy plane. An area, a display area on the z-axis having a height of “2-5”, and an input operation determination height of “2” are associated with each other. In addition, for the button ID “02”, the display area in the xy plane of “(4,2), (4,4), (6,2), (6,4)”, the height of “2-5” The display area on the z axis and the input operation determination height of “2” are associated with each other.

  FIG. 4 is a schematic diagram for explaining an example of the three-dimensional input detection function of the mobile phone 1. FIG. 4 (i) is a view of the mobile phone 1 as viewed from the front of the three-dimensional display device 11, and FIG. 4 (ii) shows the mobile phone 1 shown in FIG. 1 and FIG. 4 (i). It is the figure seen from the direction. For example, as shown in FIG. 4I, the three-dimensional display device 11 has a plurality of three-dimensional buttons (for example, “0” to “0”) that are operated by the user above the display surface 40 (in the z-axis plus direction). 9 ”three-dimensional button 41) is three-dimensionally displayed.

  Further, as shown in FIG. 4 (ii), the three-dimensional display device 11 transmits infrared rays for detecting an input medium such as a user's finger U to the display area of each three-dimensional button 41. . When the user holds the finger U over the display area of the three-dimensional button 41 as shown in (ii) of FIG. 4, infrared light is reflected by the finger U. The three-dimensional input detection unit 22 detects the reflected infrared light reflected by the user's finger U, thereby estimating the position of the user's finger U from the detected value and confirming the input process.

  In FIG. 4, in order to emphasize the three-dimensional display, the shadow of the object that is three-dimensionally upward is drawn below. Since the actual three-dimensional display is a pseudo three-dimensional display based on parallax, a shadow by an information object does not appear, but a three-dimensional effect is indicated by a shadow in the description expression.

  Here, when the user selects the desired three-dimensional button 41 while the three-dimensional button 41 of “0” to “9” is three-dimensionally displayed on the mobile phone 1, the main control unit 20 performs input control. A procedure for performing the process will be described with reference to a flowchart shown in FIG. 5 and schematic diagrams shown in FIGS. 6 (A) to 6 (C). 6A is a schematic diagram illustrating a state immediately before an input is performed on the mobile phone 1, and FIG. 6B is a schematic diagram illustrating a state where an input confirmation display is performed on the mobile phone 1. FIG. 6C is a schematic diagram illustrating a state where input is performed in the mobile phone 1.

  In the three-dimensional display device 11, as shown in (i) of FIG. 6A, three-dimensional buttons 41 “0” to “9” are three-dimensionally displayed. Specifically, the mobile phone 1 has the entire display content including a background area (area to which the user operation is not applied) 42a and a plurality of three-dimensional buttons 41 appear in three dimensions in a three-dimensional display. The rear area 42a is set and displayed on the input decision plane 42, and the height of each three-dimensional button 41 is set above the background area 42a (in the z-axis plus direction) and displayed. A three-dimensional input button similar to the input key is represented.

  When the user selects an arbitrary three-dimensional button 41 displayed in three dimensions by the three-dimensional display device 11 as shown in (i) of FIG. 6A, first, a desired three-dimensional button 41 is displayed. The finger U is positioned above the xy coordinate of the region. At this time, the input determination surface 42 for confirming the input is a plane that is horizontally moved in the positive direction of the z axis with respect to the display surface 40 of the three-dimensional display device 11. Thus, by not matching the display surface 40 and the input determination surface 42 of the 3D display device 11, the user can perform an input operation without bringing the finger U into contact with the 3D display device 11.

  The main control unit 20 determines whether a three-dimensional input is detected (S101). At this time, for example, when the three-dimensional input detection unit 22 detects a three-dimensional position such as the finger U, it is determined that a three-dimensional input has been detected. When the three-dimensional input is not detected (No in S101), the main control unit 20 waits as it is.

  When a three-dimensional input is detected (Yes in S101), the main control unit 20 acquires the detection position (value of xy coordinates) from the three-dimensional input detection unit 22 (S103). Similarly, the main control unit 20 acquires the detected height (z coordinate value) from the three-dimensional input detection unit 22 (S105).

  The main control unit 20 determines whether or not the detection position detected in step S103 is within the button area of any three-dimensional button 41 (S107). At this time, if the value of the xy coordinate of the detection position is within the area where the button image is displayed, it is determined that the value is within the button area. Based on the button display information 30, the detection positions are within rectangular areas whose vertices are, for example, (2, 2), (2, 4), (4, 2), (4, 4) If it is within a circle including the same), it is determined that it is within the button area of the three-dimensional button 41 with the button ID “01”. If the detected position is not within the button area of any of the three-dimensional buttons 41 (No in S107), the process returns to step S101, and the main control unit 20 determines again whether or not a three-dimensional input has been detected.

  When the detected position is within the button area (Yes in S107), the main control unit 20 determines whether or not the detected height acquired in Step S105 is within the button drawing range (S109). At this time, if the value of the z coordinate of the detected height is within the area where the button image is displayed in three dimensions, it is determined that the value is within the button drawing range. Based on the button display information 30, when the detected height is 2 or more and 5 or less, for example, it is determined that it is within the button drawing range of the button 41 with the button ID “01”. If the detected height is not within the button drawing range (No in S109), the process returns to step S101, and the main control unit 20 determines again whether or not a three-dimensional input has been detected.

  When the detected height is within the button drawing range (Yes in S109), the main control unit 20 determines the height (z) of the button displayed three-dimensionally according to the detected height detected in Step S105. The direction length is changed and the three-dimensional button 41 is displayed again (S111). Since the three-dimensional button 41 selected at that time is displayed in a half-pressed state, the user can confirm the three-dimensional button 41 that is expected to be input before the input is confirmed. According to the button display information 30, for example, when the detected height is 4, the height of the button drawing area of the button 41 with the button ID “01” is changed from “2-5” to “2-4”. For example, as shown in (i) and (ii) of FIG. 6B, the button 41 with the button ID “01” is displayed in a half-pressed state.

  With the processing in steps S101 to S111, when the user inputs data, the finger U is displayed on the display surface 40 in the z-axis direction so as to press the three-dimensional button 41 as shown in (ii) of FIG. The finger U is positioned in the display area in the z-axis direction of any of the three-dimensional buttons 41 as shown in (iv) of FIG. 6B. Then, as shown in FIG. 6 (iii), the height of the three-dimensional button 41 (the display area in the z-axis direction of the three-dimensional button 41) is set to match the z-axis position of the finger U. The three-dimensional button 41 is displayed again.

  As described above, when the finger U comes close to the three-dimensional button 41 displayed three-dimensionally by the user's operation, the height of the three-dimensional button 41 is increased or decreased according to the pressing operation of the finger. The user can see the same operation as pressing an actual hardware operation key, and the operation can be easily understood visually.

  At this time, the vibrator of the mobile phone 1 is gradually strengthened from the weak according to the pressing operation of the finger, and the sound effect according to the operation (sound similar to the sound of pressing the keyboard, etc.) is reproduced. By doing this, it is possible to provide a more realistic feeling of pressing the button.

  The main control unit 20 determines whether or not the detected height acquired in step S105 is the height of the input operation determination process (S113). At this time, as shown in (ii) of FIG. 6C, for example, the detection height of the user's finger U is the same as the input determination plane 42, and the z coordinate of the detection height is the selection determination plane 42. When the height is the height, the main control unit 20 determines that the height is the height of the input operation determination process. Based on the button display information 30, when the detected height is 2, for example, it is determined that the input operation determination process for the three-dimensional button 41 with the button ID “01” is performed.

  If the detected height is not the height of the input determination process (No in S113), the process returns to step S101, and the main control unit 20 determines again whether or not a three-dimensional input has been detected. When the detected height is the height of the input determination process (Yes in S113), the main control unit 20 determines that the three-dimensional button 41 is selected, and the three-dimensional button selected by the user Processing corresponding to 41 is performed (S115). At this time, as shown in (v) of FIG. 6C, the three-dimensional button 41 is displayed in a fully pressed state. Then, returning to step S101 again, the main control unit 20 determines whether or not a three-dimensional input is detected. The main control unit 20 repeats the processing of steps S101 to S115, whereby input control of the mobile phone 1 is performed.

  When the finger U moves within the display area of the three-dimensional button 41 and reaches the input decision plane 42 as shown in (vi) of FIG. 6C by the processing of steps S113 to S115, the three-dimensional The input of the button 41 is confirmed, and the display height of the three-dimensional button 41 displayed three-dimensionally by the three-dimensional display device 11 is equal to the height of the input decision plane 42 as shown in (v) of FIG. The images of the three-dimensional button 41 in the fully pressed state are displayed.

  When the three-dimensional button is selected by the user, the background region 42a (that is, the input determination surface 42) is set to a height that floats upward (z-axis plus direction) from the surface surface 40 of the three-dimensional display device 11 by three-dimensional display. By being displayed, the finger operated by the user does not directly touch the screen, and it is possible to prevent the fingerprint from attaching to the screen or damaging the screen. Further, at the time of confirming the input, it is preferable to simultaneously perform vibrations by the vibrator, decision sound, color change of the three-dimensional button 41, and the like.

  When the half-press display (display in step S111) of the three-dimensional button 41 is started in accordance with the user operation, the input of the three-dimensional button 41 has not yet been confirmed at that time. Therefore, the user confirms the three-dimensional button 41 that is being pressed at that time, and if the wrong three-dimensional button 41 is pressed, moves the finger U upward (z-axis plus direction) as it is. As a result, the display of the three-dimensional button 41 is changed from the image of the three-dimensional button 41 in the half-pressed state to the image of the three-dimensional button 41 in the state of not being pressed at all, and the input process is not performed. Then, the user can redo the selection of the desired three-dimensional button 41 from the beginning.

  In this way, the mobile phone 1 displays a user operation interface (such as the three-dimensional button 41) in a three-dimensional manner above the display surface 40 of the three-dimensional display device 11 so that the position of the user's finger U or the like is three-dimensionally displayed. In order to detect, the user's hollow operation position and the display position of the user operation interface are set to the same position and height. Thereby, user operability at the time of data input using a three-dimensional input device can be improved. That is, the mobile phone 1 provides an intuitive input interface to the user, avoids erroneous operations, and prevents device contamination.

  Further, since the mobile phone 1 has a play (margin) from the half-pressed state to the fully-pressed state of the three-dimensional button 41 at the time of user input, the user inputs while checking the selected three-dimensional button 41 at that time. As a result, it is possible to prevent an erroneous operation by the user.

  Further, for example, when the detection position is moved without changing the detection height in the half-pressed state of the three-dimensional button 41, it is regarded as an erroneous operation and input determination is not performed. Therefore, even when the position of the finger U is deviated from the three-dimensional button 41 to be operated due to the movement of the button, it is possible to prevent the process associated with the other three-dimensional button 41 from being erroneously executed. Is done.

  Further, the mobile phone 1 changes the display height (or inclination) of the three-dimensional button 41 displayed in three dimensions according to the detected height of the finger U detected by the three-dimensional input detection unit 22. In addition, the user can be prompted to make a selection action by changing the display in accordance with the selection operation by the user and by changing the volume of the sound and the vibration level of the vibrator. This is a display expression close to the feeling of pressing a physical key switch, and is easy for the user to make an intuitive determination.

  In addition, since the mobile phone 1 can perform an input operation without directly touching the display surface 40 of the three-dimensional display device 11, it is expected to prevent fingerprints and dirt from being attached to the screen or damaging the screen. .

  As an example, an example in which the height of an object (such as the three-dimensional button 41) is continuously changed according to the detection height every time the detection position of the input medium is changed has been described. Not. The mobile phone 1 stores, for example, three types of images in a state where the three-dimensional button 41 is not pressed, a fully-pressed state, and a half-pressed state in advance, and the input medium is located within the display area of the three-dimensional button 41. The three-dimensional button 41 in a non-pressed state is displayed while the input medium is not pressed, and the input medium is in a half-pressed state while being positioned in the display area of the three-dimensional button 41 but not on the input decision plane 42. The three-dimensional button 41 is displayed, and the three-dimensional button 41 in a fully-pressed state is displayed while the input medium is located in the display area of the three-dimensional button 41 and located on the input determination surface 42. Also good.

  FIG. 7A is a schematic diagram illustrating another example of a state before input is performed on the mobile phone 1, and FIG. 7B illustrates another example of a state where input is performed on the mobile phone 1. FIG. As shown in (i) and (ii) of FIG. 7A, in the three-dimensional display on the three-dimensional display device 11, the three-dimensional button 41a is three-dimensionally displayed as a plane having an inclination with respect to the display surface 40. Also good. In this case, as shown in (i) and (ii) of FIG. 7B, when the three-dimensional button 41 is switched from a state where the three-dimensional button 41 is not pressed to a half-pressed state, or from a half-pressed state to a fully-pressed state. Is changed so that the inclination becomes gentle, and when the three-dimensional button 41 is switched from the fully pressed state to the half-pressed state or from the half-pressed state to the non-pressed state, the inclination is increased. Is displayed.

  When the user's viewpoint is an oblique angle rather than directly above the display device, such as bank ATM (Automated Teller Machine), the background area is displayed horizontally and the 3D button 41a is inclined with respect to the horizontal plane. By making the display three-dimensional, the visibility can be improved. Then, every time the user's finger U comes close to the screen, the inclination of the three-dimensional button 41a is reduced, and the three-dimensional button 41a is gradually laid, and input is confirmed at a position parallel to the background area.

  Further, in the mobile phone 1, the back area (area not applied to the user operation) is not stereoscopically displayed, and only buttons and sliders that can be operated by the user, and particularly objects that are desired to be stereoscopically displayed may be displayed in a stereoscopic hierarchy. . That is, the display surface 40 and the background surface of the three-dimensional display device 11 may be set to the same height (z-axis value) and displayed. In addition, when it is difficult for the user to stereoscopically view the image, it may be configured to be able to switch to the two-dimensional display.

  According to the three-dimensional input display device (mobile phone 1) according to the present invention, it is possible to perform input by performing an operation such that the user directly touches an object displayed in three dimensions, thereby enabling the user to perform input. It is possible to provide an intuitive input environment and to prevent erroneous input.

  As an explanation of the present invention, the mobile phone 1 has been described. However, the present invention is not limited to this, but PHS (Personal Handyphone System), PDA (Personal Digital Assistants), MID (Mobile Internet Device), mobile music player, mobile video camera, mobile game Any information processing terminal may be used as long as it is an information processing terminal having a three-dimensional input display function, such as a computer.
