Description

  The present invention relates to an information input / output device for pointing an on-screen coordinate with respect to a screen by bringing an object into contact with or approaching the object, thereby inputting an instruction set according to the coordinate.

  In recent years, development of a display device with a built-in touch sensor capable of inputting information by directly touching a display screen of a display using a finger or the like has been progressing. Touch sensors include a contact type that detects a contact position of an electrode and a capacitance type that utilizes a change in capacitance, and an optical type that optically detects a finger and the like.

  Information input / output devices using a display device with a built-in touch sensor range from small devices such as smartphones and tablet terminals to huge devices such as electronic blackboards and digital signage.

  As an example of such an information input / output device, for example, in Patent Document 1, a plurality of screens are arranged on a screen by pointing the screen for a certain period of time so that the user's finger can be moved as little as possible. A display device having a touch panel that automatically rearranges several input icons located near the finger among the input icons around the finger is disclosed.

JP2011-210083 (October 20, 2011)

  However, Patent Document 1 as described above has a configuration in which the input icons are rearranged by a preset number in order from the input icon located near the finger. Therefore, when the position away from the desired input icon to be operated is pointed, the desired input icon may not be included in the rearranged input icons. In such a case, the operator has to start again from the beginning by changing the position to which the operator points.

  The number of input icons rearranged around the finger is fixed to the set number. For this reason, if the number of settings increases unnecessarily, the amount of movement of the finger or the like increases. Conversely, if the number of settings is too small, the desired input icons are not included in the rearranged ones, resulting in poor usability.

  The present invention has been made in view of the above problems, and an object of the present invention is to provide an information input / output device that is more convenient to use and can be arranged near the coordinates on the screen where a desired operation button is pointed with a finger or the like. There is.

  In order to solve the above problems, an information input / output device of the present invention is an information input / output device that inputs an instruction set according to coordinates by pointing the coordinates on the screen to the screen. A control unit that displays operation buttons that can be operated on the screen near the pointed coordinates on the screen, and the control unit indicates according to a continuation time in which the substantially same coordinate continues to be pointed It is characterized in that the combination of operation buttons to be displayed near the displayed coordinates is different.

  According to this, the combination of operation buttons displayed in the vicinity of the pointed coordinate changes depending on the duration for which the same coordinate continues to be pointed. Therefore, by remembering the relationship between the duration and the displayed combination of operation buttons, the operator can continue to point to the same coordinates for the time corresponding to the combination of operation buttons to be displayed. An operation button that is not displayed can be displayed near.

  As a result, there is no problem that the operation buttons are not displayed depending on the position indicated, there are no problems that many operation buttons are unnecessarily displayed, or the desired operation buttons are not included. It is possible to provide an easy-to-use information input / output device in which the operation buttons can be arranged near the coordinates on the screen indicated by a finger or the like.

  The information input / output device according to the present invention is configured such that the control unit displays a larger number of operation buttons as the duration time is longer, and in such a case, the operation buttons that are frequently used are displayed with priority. Is preferred.

  According to this, it is possible to display from an operation button with a high use frequency to an operation button with a low use frequency in accordance with the length of the duration of continuing to indicate substantially the same coordinates. That is, if you want to display frequently used operation buttons, keep pressing the same coordinates for a short time, and if you want to display less frequently used operation buttons, keep pressing the same coordinates for a long time. Thereby, it is possible to make the information input / output device more convenient to use.

  The information input / output device of the present invention may be configured such that the control unit visually displays the duration.

  According to this, since the display unit can visually recognize the time during which substantially the same coordinates are kept pressed, the operator can easily display a combination including a desired operation button.

  In the information input / output device according to the present invention, the control unit may further change a combination of operation buttons to be displayed even if there is an operation on a predetermined screen immediately before the coordinates on the screen are indicated. It can also be set as the structure to make.

  According to this, the combination of operation buttons to be displayed can be further varied depending on whether or not an operation on a predetermined screen has been performed immediately before the coordinates on the screen are pointed to. Therefore, more combinations of operation buttons can be arranged near the coordinates on the screen pointed by a finger or the like.

  In this case, the operation on the predetermined screen is an operation for designating a region to be processed, and the control unit operates an operation button corresponding to the region to be processed when the operation on the predetermined screen is performed. Can be configured to display.

  According to this, it is possible to display operation buttons for processing that can be performed after designating an area, and it is possible to place more combinations of operation buttons near the coordinates on the screen pointed by a finger or the like. .

A control unit that displays operation buttons operable on the screen near the pointed coordinates on the screen, and the control unit is determined in advance immediately before the point on the screen is pointed to. The combination of operation buttons to be displayed varies depending on whether or not there is an operation on the screen.

  According to this, a combination of operation buttons displayed near the indicated coordinates changes depending on whether or not an operation on a predetermined screen is performed immediately before the same coordinates are continuously indicated. Therefore, by learning the relationship between the combination of operation buttons displayed when the operation is performed on a predetermined screen and when the operation is not performed, the operator can respond to the combination of operation buttons to be displayed. By selecting whether or not to perform an operation on a predetermined screen, it is possible to display an operation button that is not displayed near the indicated coordinates.

  As a result, there is no problem that the operation buttons are not displayed depending on the position indicated, there are no problems that many operation buttons are unnecessarily displayed, or the desired operation buttons are not included. It is possible to provide an easy-to-use information input / output device in which the operation buttons can be arranged near the coordinates on the screen indicated by a finger or the like.

  The embodiment of the present invention will be described below with reference to FIGS.

  FIG. 1 is a block diagram showing a schematic configuration of the information input / output device according to the present embodiment. The information input / output device 1 is a display device having a so-called touch sensor function for inputting information using, for example, a finger or a stylus.

  As shown in FIG. 1, the information input / output device 1 includes a display unit 10, a coordinate input unit 20, a control unit 30, and a storage unit 40.

  The display unit 10 displays display information such as images, characters, and graphics together with operation buttons for receiving operation instructions for the information input / output device 1. As the display unit 10, a liquid crystal panel, an organic EL (Electro-Luminescence), a plasma display, or the like can be used.

  The coordinate input unit 20 inputs coordinates on the screen of the display unit 10. As the coordinate input unit 20, a touch sensor such as a pressure detection method, a resistance film method, a capacitance method, and an electromagnetic induction method can be used. The operator touches the screen of the display unit 10 with a finger, a pen, or the like, so that the pressing force or electric resistance at a specific place where the finger or the like is touching the coordinate input unit 20 arranged on the upper layer of the display unit 10 is detected. , Electrical capacity, elastic wave energy, etc. change. By detecting these changes, the coordinates on the screen touched by a finger or the like are specified.

  The coordinate input unit 20 may be an optical touch sensor that optically detects a finger or the like. In the optical touch sensor, for example, an object close to the display screen is illuminated using image display light or the like, and the coordinates (Xn, Yn) on the screen touched by a finger or the like based on the light reflected by the object are used. ) Is identified. In the case of the optical type, it is possible to detect not only when the object literally touches the screen of the display unit 10 but also when the object is not in contact with the screen of the display unit 10 and exists in a space from the screen to a predetermined height. .

  The storage unit 40 reads and writes data from and to a nonvolatile storage medium such as an HDD. The storage unit 40 stores display information and the like in addition to function information executed when each operation button is selected on the screen of the display unit 10.

  The control unit 30 includes a CPU and a RAM, and is connected to the display unit 10, the coordinate input unit 20, and the storage unit 40. When the operator's finger or the like touches the coordinate input unit 20 and the coordinates on the screen are indicated, the control unit 30 performs the operation when the operation button is displayed at the indicated coordinates. Executes the function (processing) set for the button.

  On the other hand, when the operation button is not displayed at the indicated coordinate, the control unit 30 displays an operation button operable on the screen near the indicated coordinate.

  Displaying near the indicated coordinates means that if the information input / output device 1 is a small device such as a smartphone or a tablet device, the operation button can be operated only by the movement of the finger with almost no movement of the arm. Range. Also, if the information input / output device 1 is a large one such as an electronic blackboard, it can be operated using a pointer, so if you want to display it near the indicated coordinates, select the operation button with the pointer. In consideration of the operability at the time of operation and the size of the operation button itself, the information input / output device 1 has a predetermined range wider than that of a small-sized smartphone or tablet device.

  In the present embodiment, the control unit 30 changes the combination of operation buttons to be displayed according to whether or not an operation on a predetermined screen has been performed immediately before pointing to the coordinates and the time for which the same coordinates are kept pointing. Make it. In the following, the time during which the same coordinates are continuously indicated is also referred to as input duration time.

  The substantially same coordinates mentioned here are the center coordinates of the region pointed by a finger or a stylus and the surrounding coordinates. When the coordinate input unit 20 is a non-contact type using an optical system, or when the information input / output device 1 is a large electronic blackboard, the position pointed at the tip of the stylus may be slightly shifted due to camera shake or the like. . In order to cover such a case, the control unit 30 continues the same coordinates even if the coordinates around the center coordinates detected first (position change within the allowable range) are newly detected as the center coordinates. Judge that it is pointed.

  In the present embodiment, a configuration in which the combination of operation buttons to be displayed is changed according to both the presence / absence of an operation on a predetermined screen and the time during which the coordinates are continuously indicated is illustrated. Alternatively, the combination of operation buttons to be displayed may be changed on the condition that only one of the time during which the coordinates are continuously indicated is used as a condition.

  In the present embodiment, as an operation for a predetermined screen that is performed immediately before pointing to the coordinates, an operation that specifies the area to be edited (area specifying operation) is exemplified. The control unit 30 displays the “region type menu” as a combination of operation buttons to be displayed when the region designation operation is performed immediately before pointing to the coordinates, and “general-purpose menu” when the region designation operation is not performed. Is displayed.

  FIG. 2 shows the types of operation buttons included in the general-purpose menu. From left to right, “Pen Point”, “Color”, “Cut”, “Paste”, “Copy”, “Search”, “Save”, “Mail”, etc. The operation buttons included in the general-purpose menu are operation buttons (operation buttons that can be operated) that can instruct execution of displayed data.

  On the other hand, FIG. 3 shows types of operation buttons included in the area type menu. From the left, “Cut”, “Copy”, “Enlarge”, “Reduce”, “Save”, “Mail”, “Color”, “Search”, etc. The operation button included in the area type menu is an operation button (operation button that can be operated) that can instruct execution of the target part included in the area designated in the displayed data.

  In the examples of FIGS. 2 and 3, some of the items of the operation buttons included in the general-purpose menu and the area-type menu are common. The area type menu includes “enlargement” and “reduction” that can be performed only by designating an area. “Enlargement” and “reduction” are not included in the general-purpose menu.

  When displaying the general-purpose menu or the area-type menu, the control unit 30 changes the combination of operation buttons to be displayed in accordance with the input duration time that is a time during which the substantially same coordinates are continuously indicated. More specifically, the number of operation buttons is varied. When the input duration time is relatively short (the first stage) that is the set time 1 or more and less than the set time 2, the control unit 30 displays only the operation buttons that are frequently used, and the set time 2 or more and the set time 3. In the case of moderately long (second stage), the number of operation buttons is displayed in the order of frequency of use more frequently than the first stage, and when the set time is 3 or more (third stage), it is used A larger number of operation buttons than the second stage including operation buttons with lower frequency are displayed (operation buttons with higher usage frequency are displayed with priority).

  In the example of the present embodiment, the setting time 1 is “0.5 seconds”, the setting time 2 is “1.0 seconds”, and the setting time 3 is “1.5 seconds”. It is set to display two operation buttons in order, five in order from the most frequently used in the second stage, and eight operation buttons in order from the most frequently used in the third stage. It is preferable that the number of operation buttons displayed in the set times 1 to 3 and the first to third stages can be arbitrarily set.

  The control unit 30 has a function of managing the use frequency of the operation buttons. The operation buttons that can be operated are arranged in descending order of use frequency, and the set number set in each stage in order from the smallest number. Display based on. In addition, when the control unit 30 does not have a function for managing the use frequency of the operation buttons, the user designates the combination of the operation buttons displayed at each stage in order from the highest use frequency. Also good.

  Further, the control unit 30 is configured to visually and visually convey the length of the input continuation time so that the time (input continuation time) during which substantially the same coordinates continue to be indicated is transmitted to the operator as an image. Specifically, for example, as shown in FIG. 4, the control unit 30 uses the display unit 10 to set a ring R (R1, R2, R3) having a diameter corresponding to the input duration as the input duration. Display accordingly. The center of the ring R is the indicated coordinate, and the rings R1, R2, R3 are concentric circles.

  The ring R1 having the smallest diameter is displayed until the input duration is set time 1 or more and less than set time 2, and when the set time is 2 or more, ring R1 is turned off and ring R2 having a medium diameter is displayed. When the set time is 3 or more, the ring R2 is erased and the ring R3 having the largest diameter is displayed. When the ring R2 or R3 is displayed, the previously displayed ring R1 or the rings R1 and R2 may be left in a state of visually expressing that the ring R2 or R3 cannot be selected as in the gray-out display.

  If the display unit 10 can perform color display, the colors of the rings R may be different. Further, when the information input / output device 1 has a function of producing a sound, it is displayed to the operator by changing the melody or changing the scale at the timing of changing the size of the ring R. It may be effectively notified that the menu to be changed is changed.

  In the present embodiment, when detecting the completion of an operation that can continue to indicate substantially the same coordinates (indication completion), the control unit 30 displays a set number of operation buttons according to the input duration time. At that time, as shown in FIG. 4, the control unit 30 displays the operation buttons so as to be superimposed on the ring R displayed with the indicated coordinates as the center. Therefore, in the present embodiment, the diameters of the rings R1, R2, and R3 are set to sizes that can display a set number of operation buttons.

  FIG. 4 is an explanatory diagram illustrating an operation for displaying a general-purpose menu on the display unit 10. If the area designation operation is not performed and an area other than the operation button is continuously pointed to for the set time 1 or more, one of the three general-purpose menus (1) to (3) is displayed according to the input duration time. The In the general-purpose menu (1) displayed in the first stage, two operation buttons of “pen point” and “color” are displayed on the ring R1. In the general-purpose menu (2) displayed in the second stage, in addition to “pen point” and “color”, five operation buttons of “cut”, “paste” and “copy” are displayed on the ring R2. ing. In the general-purpose menu (3) displayed in the third stage, eight operation buttons including “search”, “save”, and “mail” are further displayed on the ring R3.

  FIG. 5 is an explanatory diagram showing an operation for displaying the area type menu on the display unit 10. An area designation operation is performed, and the designated area is continuously pointed to for a set time 1 or more, so that one of three types of area type menus (1) to (3) is displayed according to the input duration time. . Here, a pie chart 55 shown in a three-dimensional perspective view is set as a processing object, and an area designation process such as enclosing the pie chart 55 with a stylus 50 is performed. At this time, it is preferable that the control unit 30 displays the miracle 60 of the stylus 50 until at least the next operation for designating the inside of the region (the inside of the miracle 60) is completed.

  By pointing the coordinates in the area, the three types of rings R1 to R3 with different diameters are sequentially displayed according to the length of the input continuation time, which is the time to continue pointing, and the completion of the operation that can continue pointing. 4 is the same as the general-purpose menu shown in FIG. 4 in that a set number of operation buttons are displayed over the ring R1, R2 or R3 at the timing of detecting. However, as shown in FIG. 5, when the region specifying operation is an operation of enclosing the processing object with a circle, there is a possibility that the circle of the miracle 60 and the rings R <b> 1 to R <b> 3 overlap to make it difficult to visually recognize. For this reason, in the present embodiment, the rings R1 to R3 are displayed as ellipses, are circular at the timing when the area type menus (1) to (3) are displayed, and the operation buttons are displayed over the circles. Yes.

  In order to take on the functions as described above, the control unit 30 includes the display content information displayed on the display unit 10 and the coordinate information indicated by the operator input from the coordinate input unit 20. Measure the input duration from the operation detection unit that detects the content instructed by the operator, the display control unit that controls the display unit 10, and the coordinate information indicated by the operator that is input from the coordinate input unit 20. And a time measuring unit to perform.

  FIG. 6 shows a flowchart of display processing in the information input / output device 1. First, as shown in step S1, the operator touches the coordinate input unit 20 arranged on the upper layer of the display unit 10 with a stylus 50 or the like. At this time, the coordinate input unit 20 detects the coordinates on the display unit 10 pointed to by the stylus 50. Then, as shown in step S2, it is determined whether the coordinates on the display unit 10 pointed to by the operator are the operation button area in which the operation button is displayed. Since the operation button represents the content and object of processing on the operation screen with a small picture or figure, the operation button has an area corresponding to the area corresponding to the small picture or figure on the screen. This area is an operation button area.

  If “YES” in step S2 (if the indicated coordinate is an operation button), it is recognized that the operation button has been selected, and the process proceeds to S17 to execute processing of the operation button.

  On the other hand, if “NO” in step S2 (if the indicated coordinate is not an operation button), the process proceeds to step S3, and an area designating operation for enclosing a certain area from the coordinates detected by the coordinate input unit 20 is performed. Determine whether has been made. Here, in the case of “YES” (when an area designating operation is performed), the process proceeds to step S4, and the process proceeds to an area type menu display process. On the other hand, in the case of “NO” (when the region designation operation is not desired), the process proceeds to step S21 and proceeds to the general-purpose menu display process.

  First, a description will be given from the case of proceeding to the area type menu display process. In step S4, the control unit 30 determines whether or not the indicated coordinates are located within the area designated in step S3. Here, in the case of “NO” (when it is outside the designated area), the process proceeds to step S18, and all the operations received from step S1 to now are canceled.

  On the other hand, if “YES” in the step S4 (if it is within the designated area), the process proceeds to a step S5 to determine whether or not the input duration time is equal to or longer than the set time 1. Here, if “NO” (less than the set time 1), the process proceeds to step S18, and all the operations received so far from step S1 are canceled.

  On the other hand, if “YES” in the step S5 (when the set time is 1 or more), the process proceeds to a step S6 to display the ring R1. Subsequently, in step S7, it is determined whether or not the operation for indicating substantially the same coordinates has been completed by moving the stylus 50 away from the screen of the display unit 10 or the like. Here, in the case of “YES” (when the completion of the operation is detected), the process proceeds to step S16, and the area type menu (1) is displayed near the indicated coordinates.

  On the other hand, if “NO” in the step S7 (when the completion of the operation is not detected), the process proceeds to a step S8 to determine whether or not the input duration time is equal to or longer than the set time 2. Here, if “NO” (less than the set time 2), the process returns to step S7. On the other hand, if “YES” in the step S8 (when the set time is 2 or more), the process proceeds to a step S9 to display the ring R2.

  Subsequently, in step S10, it is determined again whether or not the operation for indicating substantially the same coordinates has been completed. Here, in the case of “YES” (when the completion of the operation is detected), the process proceeds to step S15 and the area type menu (2) is displayed near the indicated coordinates.

  On the other hand, if “NO” in step S10 (when the completion of the operation is not detected), the process proceeds to step S11, and it is determined whether or not the input duration time is equal to or longer than the set time 3. Here, if “NO” (less than the set time 3), the process returns to step S10. On the other hand, if “YES” in the step S8 (when the set time is 3 or more), the process proceeds to a step S12 to display the ring R3.

  Subsequently, in step S13, it is determined whether or not the operation indicating the coordinates is completed again. Step S13 is repeated until “YES” is determined. If "YES" is determined in step S13 (detection of completion of operation), the process proceeds to step S14, and the area type menu (3) is displayed near the indicated coordinates.

  On the other hand, if “NO” is determined in step S3 and the process proceeds to step S21 to proceed to the general-purpose menu display process, S21 to 33, which are the same processes as S5 to S18, are performed and indicated. A general-purpose menu (1), a general-purpose menu (2), or a general-purpose menu (3) is displayed near the coordinates that have been set according to the input duration time.

  As described above, in the present embodiment, the information input / output device 1 includes the control unit 30 that displays the operation buttons that can be operated on the screen near the indicated coordinates on the screen. Is a combination of operation buttons for displaying a combination of operation buttons to be displayed near different specified coordinates, depending on the duration for which the same coordinates are generally indicated and the presence or absence of an operation on a predetermined screen. It will be different.

  As a result, there is no problem that the operation buttons are not displayed depending on the position indicated, there are no problems that many operation buttons are unnecessarily displayed, or the desired operation buttons are not included. It is possible to provide an easy-to-use information input / output device in which the operation buttons can be arranged near the coordinates on the screen indicated by a finger or the like.

  Further, in the present embodiment, the information input / output device 1 uses the general-purpose menus (1) to (3) and the area type menus (1) to (3) as specific examples to display near the indicated coordinates. An example is shown in which the ring R1, R2, R3 displayed on the screen is displayed in an overlapping manner. However, for example, as shown in FIG. 7 as an example of displaying a general-purpose menu, the operation buttons may be displayed in a straight line near the indicated coordinates.

  Further, in the present embodiment, the information input / output device 1 displays an operation button at the timing when the completion of an operation (pointing completion) that can continue to indicate substantially the same coordinates is detected. However, as shown in FIG. 7, the general-purpose menu (1) is displayed when the input duration becomes the set time 1 or more, and the general-purpose menu (2) when the input duration becomes the set time 2 or more. It is good also as a structure which switches to general-purpose type menu (3) when input continuation time becomes set time 3 or more.

  Furthermore, in the present embodiment, the information input / output device 1 has exemplified the configuration in which the region is enclosed in a circle as the region designation operation, but may be enclosed in a rectangle as shown in FIG. In addition, as an operation to be performed in advance, an area specifying operation that is specified by surrounding an area to be edited in advance has been exemplified. However, the operation is not limited to the area specification. For example, after setting a circle, an operation that points to the area is set. Operation buttons that are not frequently used and that are not displayed even when the operation exceeds time 3 may be displayed.
