Description

  The present invention relates to an input device that accepts an input operation via a touch panel, an input support method, and a program.

  In recent years, electronic devices equipped with a touch panel are increasing. A touch panel that can be operated intuitively by a user is widely used as a device that receives an input operation of an electronic device. The touch panel has the same reception of an input operation for a screen of a display unit (for example, an LCD (Liquid Crystal Display) or an organic EL (Electroluminescence) display) provided in the electronic device and a display of a processing result of the electronic device for the input operation. Allows you to do it in the screen.

  A multi-function mobile phone terminal provided with the touch panel on the front surface of the apparatus housing, that is, a so-called smartphone is also widely known. In addition to the telephone function, the smartphone has a function as a personal computer such as connecting to the Internet via wireless to acquire information. In general, the user supports the device housing of the smartphone with one hand, and performs an input operation from the touch panel with the finger of the other hand, but the need for one-handed operation is also high. That is, by supporting the device housing of the smartphone with four fingers excluding the thumb and the palm and performing an input operation with the remaining thumb, an operation with only one hand becomes possible.

  However, when performing this one-hand operation, the thumb is usually not supported by the upper part of the touch pal because the operation is performed with the thumb while supporting the back surface of the lower part of the touch panel, making it difficult to perform the input operation. It is. In particular, this operation becomes more difficult as the touch panel becomes larger. Therefore, as a well-known technique, the screen displayed on the touch panel can be moved up and down by a scroll operation, and the screen above the touch panel can be moved downward to facilitate the input operation. This scroll operation is shown in Patent Document 1, for example.

  Patent Document 1 discloses an electronic device that performs scrolling in the direction of a flick operation when it is determined that a finger flicks an object.

  However, in order to be able to scroll on all application screens that operate on a smartphone, it is necessary to design the screen to be scrollable in the vertical direction for all screen displays held by the application. There has been a problem of increasing the development load, resulting in an increase in the manufacturing cost of the device. In addition, general smartphones have a function that enables downloading and installation of applications created by third parties, so that all screens can be scrolled to applications created by such third parties. It is difficult.

  In order to solve the above-described conventional problems, an object of the present invention is to provide an input device, an input method, and a program that can easily move the screen of a touch panel to one side with a simple device configuration.

An input device according to the present invention includes a display unit capable of displaying a screen and an input unit capable of accepting an operation. When the display unit displays the first screen, the input unit When the first operation is received, the display unit draws the first screen as if it were scrolled, and the first screen is arranged at a position away from the one end of the display unit by a first amount. When the input unit receives a second operation in a state in which the screen is displayed and the display unit is displaying the second screen, the first screen is moved from the one end of the display unit to a second amount. When the third screen is displayed at a distant position and the display unit displays the third screen, the display unit always receives the third operation when the input unit receives a third operation. Display the first screen by scrolling the first screen in three screens Back to to have the state.

  Embodiments of an input device, an input support method, and a program according to the present invention will be described below with reference to the drawings. The input device of the present embodiment is an electronic device including a display unit that displays data on a screen, and is, for example, a mobile phone, a smartphone, a tablet terminal, a digital still camera, a PDA (personal digital assistant), or an electronic book terminal. Hereinafter, a smartphone will be used as an example of the input device according to the embodiment.

  The present invention can also be expressed as an input device as a device or a program for operating the input device as a computer. Furthermore, the present invention can also be expressed as an input support method having each operation (step) executed by the input device. That is, the present invention can be expressed in any category of an apparatus, a method, and a program.

  In the following description, a user's thumb is used as an example of an object (indicating medium) that touches (including proximity; the same applies hereinafter) to the touch panel, but is not limited to a finger, and may be a conductive stylus. The object touching the touch panel is not limited as long as the touch to the touch panel can be detected according to the structure of the touch panel and the detection method.

  The “tap” is an operation of tapping the touch panel with an instruction medium, and the apparatus determines that it is a “tap” by a predetermined short time contact.

  The two axes representing the horizontal plane of the touch panel are the x-axis and the y-axis, and “contact coordinates” are coordinates (x, y) for specifying the position on the horizontal plane of the touch panel when the touch panel detects a finger contact. Indicates.

  Furthermore, in the following description, a process of copying and holding an image displayed on the surface of the touch panel as it is is defined as a “capture process”.

  First, operation | movement of the smart phone of one Embodiment of this invention is demonstrated with reference to FIG. FIG. 1 is an explanatory diagram showing transition of screen display on a touch panel and display screen (hereinafter referred to as a touch panel) 1 provided on the front surface of a smartphone.

  FIG. 1A shows an initial screen of the touch panel 1, and four icons 2 are displayed at the top of the screen. The icon 2 has a role of activating an application associated with each icon 2 when the user touches with a finger. In the lower part of the initial screen, a mark 3 is displayed for instructing to lower the initial screen for display.

  When the user touches the mark 3 with a finger (for example, thumb) FG on the initial screen of FIG. 1A, the initial screen is directed toward the lower part of the touch panel 1 as shown in FIG. A certain amount is reduced and displayed. Thus, for example, when performing a one-hand operation, the user can touch the icon 2 located at the upper part of the screen where the thumb cannot reach.

  FIG. 1 (c) shows that the initial screen can be scrolled by moving the finger FG up and down while keeping the finger FG in contact with the initial screen shown in FIG. 1 (b). Yes. Note that this scrolling operation is for making a fine correction of the screen position and is not necessarily performed.

  Next, the user taps the desired icon 2 with the finger FG, as shown in FIG. On the tapped icon 2, a pointer (for example, a circle) indicating contact is displayed as shown in FIG. With this display, the user can confirm whether the desired icon 2 has been tapped. In the present embodiment, a pointer is displayed for the tapped icon 2, but this display is not limited to the pointer, and any display that allows the user to recognize that it has been tapped may be used.

  Thereafter, the initial screen is pulled up to the upper end of the touch panel 1 as shown in FIG. Then, as shown in FIG. 1G, it is determined that the icon 2 tapped with the finger FG is selected, and the function assigned to the selected icon 2 is executed.

  The above is the transition of the display operation of the touch panel 1 in the embodiment of the present invention. A specific configuration for performing this display operation will be described below.

  FIG. 2 is a block diagram showing a configuration of a smartphone 100 according to an embodiment of the present invention, in which 1 is a touch panel, and more specifically, includes an input unit 101 such as a touch panel and a display unit 102 such as a display. Has been. In the present embodiment, the input unit 101 and the display unit 102 are integrally formed. However, it is not always necessary for the both to be completely integrated. For example, a part of the input unit is attached to the housing of the smartphone 100. You may form with the provided physical key.

  Reference numeral 103 denotes a coordinate conversion unit that converts position coordinates (x, y) at which the finger FG contacts a captured screen (described later) into position coordinates (x, y) of the original screen. Reference numeral 104 denotes a memory that holds the position coordinates with which the finger FG is in contact and the amount of deviation (described later).

  A control unit 105 is configured by using, for example, a CPU (Central Processing Unit), an MPU (Micro Processing Unit), or a DSP (Digital Signal Processor), and includes an input unit 101, a display unit 102, a coordinate conversion unit 103, and a memory. Each unit 104 is controlled to perform various processes in an embodiment described later.

  Next, the operation | movement outline | summary of the smart phone 100 of this embodiment is demonstrated using FIG.3 and FIG.4. FIG. 3 is a flowchart for explaining the operation of the present embodiment, and shows the operation of the smartphone 100 when an input is made from the input unit 1 with the user's finger FG. FIG. 4 is an explanatory diagram showing the transition of the screen display shown in FIG. 1 in more detail.

  First, the control unit 105 detects whether or not the user's finger FG has touched the input unit 101, that is, whether or not an input operation has been performed (ST1). Here, if it is determined that there is no input operation, the detection of the input operation is continued. If it is determined that there has been an input operation, it is next determined whether or not the function (hereinafter referred to as this function) for performing input by pulling down the screen shown in FIGS. .

  If it is determined that this function is not in operation (determined NO in ST2), in other words, if it is determined that the touch panel 1 is not in any of the states shown in FIGS. It is determined whether or not to call (ST3). Specifically, it is determined whether or not the user's finger FG has touched the mark 3 (see FIG. 1A) displayed at the bottom of the screen. In the present embodiment, the determination is made based on whether or not the mark 3 is touched. However, the determination is made based on whether or not a physical key provided on the housing of the smartphone 1 is pressed or whether or not there is a predetermined movement with the finger FG. It is good also as composition which performs.

  If it is determined that the input operation does not call this function (determined NO in ST3), the process returns to ST1 to detect whether or not there is a new input operation.

  If it is determined that the input operation is to call this function (YES in ST3), then capture processing is performed (ST4). Here, the capture process will be described with reference to FIG. As described above, the capture process is a process of copying and holding the image displayed on the surface of the touch panel 1 as it is, and an input operation is performed on the mark 3 in FIG. Then, it means a process of copying and holding all the images on the screen A (the screen described as the initial screen in FIG. 1) on which the input operation has been performed, together with the coordinate positions.

  After the capture process is performed (ST4), screen generation is performed (ST5). This screen generation is to draw the image held in the capture process in ST4 on another screen. That is, as shown in FIG. 4B, a new screen B is generated separately from the screen A, and the image held in the capture process of ST4 is drawn on the screen B. Note that the newly generated screen B is the same display screen as the screen A, but it is simply a drawing of the image held in the capture process, so the application is owned like the screen A. It is not a screen to do.

After screen generation (ST5), the newly generated screen is displayed (ST6). More specifically, the newly generated screen B is first displayed on the touch panel 1 in place of the original screen A, as shown in FIG. That is, the screen A is hidden by the screen B, and the screen A is not displayed on the display unit 2.

  Next, as shown in FIG. 4C, the screen B is drawn and displayed as if it is scrolled down the touch panel 1 by a certain distance α. When the screen B is drawn as if it is scrolled downward, a blank portion is generated by a fixed distance α. In this embodiment, this blank portion is displayed in black. This blank portion may be other than the black display, but if it is displayed even on a part of the screen A, the user will be confused with the screen B, so the screen A is not displayed at all. The form is desirable. After the new screen B is displayed (ST6), the process returns to ST1 to detect whether or not a new input operation has been performed.

  Next, a case will be described in which it is determined that an input operation has been performed (YES in ST1) and it is determined that this function is in operation (determined YES in ST2).

  If it is determined that this function is in operation (YES in ST2), it is first determined whether or not the input operation is to end this function (ST7). The input operation for ending this function is, for example, pressing a stop key (not shown). If it is determined that this input operation is performed (YES in ST7), a new screen B created by the capture process is displayed. Discard (ST8), and then return to ST1 to detect whether or not there is a new input operation.

  If it is determined that the input operation does not end this function (NO in ST7), it is then determined whether or not the input operation scrolls the screen (ST9). Here, the scrolling is for finely correcting the screen position as shown in FIG. Note that the blank portion of the screen B is changed by this scrolling. Further, the input operation for scrolling the screen is as shown in FIG. 4D, and the user moves up or down by touching the finger FG with respect to the screen B drawn by being drawn below the touch panel 1. It is an action to make.

  If it is determined that the input operation is to scroll the screen (YES in ST9), the screen B is moved by the movement amount of the finger FG (ST10), and then the process returns to ST1 to determine whether or not there is a new input operation. Is detected.

  If it is determined that the input operation does not scroll the screen (NO in ST9), it is then determined whether or not the input operation is a tap (ST11). If it is determined that the input operation is not a tap (NO in ST11), the process returns to ST1 to detect whether or not there is a new input operation.

  On the other hand, if it is determined that the input operation is a tap (YES in ST11), a pointer is drawn at a position on the tapped screen B (ST12). At the same time, the tapped position on the screen B is held in the memory 104 as a contact coordinate.

  Next, the distance in the y-axis direction of the blank portion on the screen B is held in the memory 104 as the shift amount β (ST13).

  That is, in this embodiment, as shown in FIGS. 4E and 4F, when the user taps on the screen B, a circular pointer is displayed at the tapped screen position and the screen position is displayed. The contact coordinates are held in the memory 104 together with the shift amount β.

  After holding the shift amount β (ST13), as shown in FIG. 4G, the screen B is drawn and displayed as if it was scrolled to the upper end of the touch panel 1 by the shift amount β (ST14). Then, when the screen B has finished displaying the drawing scrolled to the upper end of the touch panel 1, the screen B generated by the capture process is discarded (ST15). At this time, the screen B is not displayed on the touch panel 1, and the screen A that was the original display screen is displayed instead, as shown in FIG. Note that, as shown in FIG. 4G, the screen B is drawn and displayed as if it was once scrolled to the upper end of the touch panel 1 in order to prevent the user from feeling uncomfortable because the screen suddenly changes. .

  Finally, the control unit 105 reads the tapped contact coordinates and the shift amount β stored in the memory 104 and inputs them to the coordinate conversion unit 103. The coordinate conversion unit 103 adds the deviation amount β to the input unit 101 and adds the shift amount β to the y-axis coordinate as it is for the input contact coordinate. The input unit 101 outputs the input coordinates to the control unit 105 as tapped coordinates with respect to the screen A.

  The control unit 105 determines that tapping has been performed on the contact coordinates after the coordinate conversion, and if the icon 2 exists at the contact coordinates, as shown in FIG. Is performed on the display unit 102, and the function assigned to the icon 2 located at the contact coordinates is executed (ST16). Then, after the execution of the function is completed, the process returns to ST1 to detect whether or not a new input operation has been performed.

  As described above in detail, in the present embodiment, the capture process (ST4) is performed to generate a new screen (ST5), and the newly generated screen is displayed below the touch panel 1. Scroll display (ST6), scroll display (ST10) for adjusting the screen position, and scroll display (ST14) upward on the touch panel 1, and the contact coordinates for the newly generated screen are converted to simulate Tapping process (ST16).

  Therefore, a series of control by the control unit 105 is used for a smartphone or the like because it only needs to provide a capture function and a pseudo tap process compared to the case of controlling the screen held by the application. The need to modify the operating system (Operating System, OS) is kept to a minimum and can be realized by simple programming. In other words, according to the present embodiment, any application created by a third party can be scrolled to the bottom of the screen without being implemented for each application.

  In the present embodiment, the screen generated by the capture process is configured to be lowered by a certain amount below the touch panel, but may be configured to move a certain amount in the horizontal direction of the touch panel, for example. Thereby, for example, when the smartphone is arranged in a landscape rather than a portrait, the screen can be moved toward the dominant arm.

  Further, the present invention is not limited to such an embodiment. It is obvious for those skilled in the art that variations and modifications of the embodiments and examples of combinations of the embodiments can be conceived within the scope of the claims, and these are also obvious. It is understood that they belong to the technical scope of the present invention.

  The present invention is useful as an input device that accepts an input operation via a touch panel having a display function, an input support method, and a program.
