Description

  The present invention relates to an input receiving apparatus, an input receiving method, and a program for realizing these by a computer suitable for preventing erroneous input when receiving an instruction input based on a touch operation.

  2. Description of the Related Art An input receiving device that includes a touch screen (touch panel) and receives an instruction input based on a touch operation is known. In such an input reception device, the touch screen functions not only as a monitor but also as an input interface for receiving an operation input from the user. That is, an operation in which the user touches the touch screen with a touch pen or the like is accepted as an operation from the user, and processing corresponding to the accepted operation is performed.

  For example, Patent Document 1 discloses a game device that interprets a user's operation input made via a touch screen as a command. Here, in order for an operation performed on the touch screen to be interpreted as a correct command, it is required that the touch screen is operated accurately. The touch screen may function as a button.

  For example, when an image representing a determination button is displayed on the touch screen, the determination process is executed when a region where the image is displayed is touched with a touch pen. Further, for example, when a plurality of images each representing one of the options are displayed on the touch screen, if the area where any one of the images is displayed is touched with the touch pen, the touch is performed. One option represented by the image displayed in the selected area is selected.

Japanese Patent No. 3853342

  However, when the input receiving device including the touch screen is small, the surface area of the touch screen is relatively small. Therefore, it is often difficult to accurately operate the touch screen provided in the small input receiving device. In addition, for example, when a user in a train that vibrates greatly operates such an input reception device, an erroneous input may occur. For this reason, if the input receiving device is configured so that the processing is executed only by touching a predetermined area on the touch screen once, the processing may be erroneously executed. Accordingly, there is a need for an input receiving device that can reliably receive an instruction input desired by a user based on a touch operation from the user.

  The present invention has been made in view of the above problems, and an input receiving device, an input receiving method, and the like that are suitable for preventing erroneous input when receiving an instruction input based on a touch operation, and realizing them by a computer The purpose is to provide a program to do this.

  In order to achieve the above object, an input reception device according to a first aspect of the present invention includes a display unit, a detection unit, a storage unit, an increase unit, and an output unit, and is configured as follows.

  First, the display unit displays a specific area to be touched by the user on the screen. A method for displaying the specific area is arbitrary. For example, the display unit can present the specific area by displaying some image on the specific area on the touch screen. At this time, the image displayed in the specific area can be an image related to an instruction input to be received from the user. For example, when receiving an instruction input for determining to execute a certain process from the user, the display unit displays an image representing a determination button in the specific area.

Then, the detection unit detects a position where the user is touching the screen. For example, the detection unit detects the position on the touch screen where the pen tip of the touch pen or the fingertip of the user is touched. The position on the touch screen is specified by, for example, coordinates on the X axis parallel to the touch screen surface and coordinates on the Y axis parallel to the touch screen surface and orthogonal to the X axis.
In addition, a display part and a detection part can be comprised with a touch screen.

  Here, a counter value having a predetermined initial value is stored in the storage unit. Typically, 0 is stored in the storage unit as the initial value of the counter value. The storage unit is realized by a semiconductor memory such as SRAM or DRAM, for example.

  Then, the increase unit increases the counter value stored in the storage unit with the passage of time while the position detected by the detection unit continues to be included in the specific area. For example, while the specific area on the touch screen is being touched, the increase unit increases the counter value by one each time a timer interrupt with a generation period of 10 msec occurs. That is, the counter value is a value representing the time during which the specific area is touched.

  On the other hand, when the counter value exceeds the threshold value, the output unit outputs that the user has input an instruction. In other words, the output unit accepts an instruction input from the user when the specific area is touched by the user for a certain time or longer, and executes a process corresponding to the accepted instruction input. As described above, an instruction input from the user can be considered as a button operation from the user. For example, when the timer interrupt generation period is 10 msec, the threshold is 200, and an image representing a determination button is displayed in the specific area, the user determines that the specific area is continuously touched for 2 seconds or more. It is assumed that the button has been pressed, and the corresponding process is executed. On the other hand, in a state where the user cannot touch the specific area for a predetermined time or longer, the instruction input desired by the user is not accepted. As such a state, for example, a state where the user is in a train with great shaking, a state where the user is walking, and the like can be considered. According to the input reception device of the present invention, when the user is in such a state, it is possible to prevent an operation input from being erroneously received from the user. Then, it can be expected that the user does not perform operation input in such a state. For example, it can be expected that a user who is walking stops his / her foot and performs an operation input.

  According to the input receiving device of the present invention, erroneous input can be prevented when receiving an instruction input based on a touch operation.

  In the input reception device of the present invention, the display unit can be configured as follows.

That is, the display unit further displays the counter value on the screen while the position detected by the detection unit continues to be included in the specific area. For example, the display unit displays an image (figure) representing the counter value stored in the storage unit in a predetermined area on the touch screen. Note that the image representing the counter value may be any image that can represent the counter value. For example, the image representing the counter value may be an image representing the counter value by a numerical value, an image representing the counter value by a graph (bar graph, pie chart, etc.), an image representing the counter value by color, an image representing the counter value by size, or The counter value can be an image representing the shape. Note that the image representing the counter value may be an image displayed in the specific area. For example, when the determination button is displayed in the specific area, the determination button is displayed in gray in the initial state, and when the specific area is continuously touched, the color of the determination button is gradually displayed in black. In this way, when the image representing the counter value is displayed, the user can determine the elapsed time since the start of the touch operation on the specific area and the time until the instruction input is accepted.
According to the input reception device of the present invention, it is possible to present the time until the instruction input desired by the user is received.

  Moreover, the input reception apparatus of this invention can be provided with the reduction part shown below.

  That is, the decrease unit decreases the counter value with time until the specific area is not touched until the initial value is reached. The period in which the specific area is not touched is a period in which the user is not touching the screen or the detected position is not included in the specific area. For example, the decrementing unit decrements the counter value stored in the storage unit by 1 each time a timer interrupt occurs every 10 msec. However, the decrease unit does not decrease the counter value when the counter value is 0, which is the initial value.

  The reason why the input receiving apparatus includes the decrease unit as well as the increase unit in this way is because it may be desirable to receive the instruction input in consideration of not only the time when the specific area is touched but also the time when the specific area is not touched. It is. For example, even if there is a period in which the specific area has been touched in the past, if the period in which the specific area is not subsequently touched becomes long, the period in which the specific area has been touched in the past does not contribute to the reception of the instruction input.

  Here, by adjusting the speed at which the counter value is increased while the specific area is touched and the speed at which the counter value is decreased while the specific area is not touched, the time required for receiving the instruction input is adjusted. It is possible to adjust the incidence of erroneous input. For example, if the speed at which the counter value is increased is increased or the speed at which the counter value is decreased is decreased, it is expected that the time required for receiving the instruction input is shortened. On the other hand, if the speed at which the counter value is increased is decreased or the speed at which the counter value is decreased is increased, it is expected that the incidence of erroneous input is lowered.

  According to the input reception device of the present invention, it is possible to appropriately receive an instruction input from the user based on the time when the specific area is touched and the time when the specific area is not touched.

In the input reception device of the present invention, the display unit can be configured as follows.
That is, the display unit moves the place where the specific area is displayed in the screen while the detected position is continuously included in the specific area. That is, the display unit changes the position on the touch screen that displays the image indicating the specific area. On the other hand, in order to accept an instruction input, the user needs to move the touch position so as to trace an image representing a specific area. Therefore, when the user is in a stable state where an image showing a specific area can be traced, an instruction input is accepted. On the other hand, if the user is in an unstable state where the image indicating the specific area cannot be traced, the instruction input is not accepted.
According to the input receiving device of the present invention, erroneous input can be prevented when receiving an instruction input based on a touch operation.

  In order to achieve the above object, an input reception method according to another aspect of the present invention is an input reception method executed by an input reception device including a display unit, a detection unit, a storage unit, an increase unit, and an output unit. And a display process, a detection process, an increase process, and an output process, which are configured as follows.

  First, in the display step, the display unit displays a specific area to be touched by the user on the screen. For example, the display unit can present the specific area by displaying some image on the specific area on the touch screen.

  In the detection step, the detection unit detects a position where the user is touching the screen. For example, the detection unit detects the position on the touch screen where the pen tip of the touch pen or the fingertip of the user is touched.

  Here, a counter value having a predetermined initial value is stored in the storage unit. Typically, 0 is stored in the storage unit as the initial value of the counter value.

  In the increasing process, the increasing unit increases the counter value stored in the storage unit with the passage of time while the position detected by the detecting unit continues to be included in the specific area. For example, the increase unit increases the counter value by one at a predetermined cycle while a specific area on the touch screen is being touched.

  On the other hand, in the output step, when the counter value exceeds the threshold value, the output unit outputs that an instruction input from the user has been made. In other words, the output unit accepts an instruction input from the user when the specific area is touched by the user for a certain time or longer, and executes a process corresponding to the accepted instruction input.

  According to the input receiving method of the present invention, erroneous input can be prevented when receiving an instruction input based on a touch operation.

A program according to another aspect of the present invention is configured to cause a computer to function as each unit of the above-described input reception device, or to cause the computer to execute each step of the above-described input reception method.
The program of the present invention can be recorded on a computer-readable information recording medium such as a compact disk, flexible disk, hard disk, magneto-optical disk, digital video disk, magnetic tape, and semiconductor memory. The above program can be distributed and sold via a computer communication network independently of the computer on which the program is executed. The information recording medium can be distributed and sold independently of the computer.

  According to the present invention, it is possible to provide an input receiving device, an input receiving method, and a program for realizing these by a computer suitable for preventing erroneous input when receiving an instruction input based on a touch operation. it can.

  A memory cassette 106 (details will be described later) in which a game program and data are stored is mounted in a slot (not shown) connected to the interface 104, and the information processing apparatus 100 is turned on. This program is executed, and the input receiving device of this embodiment is realized. It is assumed that a program for executing an input receiving process to be described later is included in the game program.

  The CPU 101 controls the overall operation of the information processing apparatus 100 and is connected to each component to exchange control signals and data. The CPU 101 acquires various types of data from each component, processes the various types of data by various calculations, and provides the data to each component as data and control signals. In the CPU 101, various types of data are temporarily stored in a cache included in the CPU 101, and are further acquired in a register included in the CPU 101, and then various calculations are performed.

The ROM 102 stores an IPL (Initial Program Loader) that is executed immediately after the power is turned on. When the CPU 101 executes this IPL, the program recorded in the memory cassette 106 or the like is read out to the RAM 103, and execution by the CPU 101 is started.
The ROM 102 stores an operating system program and various data necessary for operation control of the entire information processing apparatus 100.

  The RAM 103 is for temporarily storing data and programs, and holds programs and data read from the memory cassette 106 and the like.

  A memory cassette 106 detachably connected via the interface 104 stores a read-only ROM area for storing a game program and image data and sound data used in the program, and data such as a play result.

  The image processing unit 107 processes the data read from the memory cassette 106 by the CPU 101 or an image arithmetic processor (not shown) included in the image processing unit 107, and then processes the processed data in a frame memory ( (Not shown). The image information recorded in the frame memory is converted into a video signal at a predetermined synchronization timing and output to a touch sensor type display (touch screen 108). Thereby, various image displays are possible.

  The image calculation processor can execute a two-dimensional image overlay calculation, a transmission calculation such as α blending, and various saturation calculations at high speed. In addition, the polygon information arranged in the three-dimensional virtual space and added with various texture information is rendered by the Z buffer method, and a rendering image obtained by overlooking the polygon arranged in the three-dimensional virtual space from a predetermined viewpoint position is obtained. High speed execution of the obtained operation is also possible. In particular, a function for calculating the degree to which a polygon is illuminated by a typical (positive) light source such as a point light source, a parallel light source, or a cone light source is made into a library or hardware so that it can be calculated at high speed.

  Further, the CPU 101 and the image arithmetic processor cooperate to draw a character string as a two-dimensional image in the frame memory or draw it on the surface of each polygon according to the font information that defines the character shape. Is possible. The font information is recorded in the ROM 102, but it is also possible to use dedicated font information recorded in the memory cassette 106.

  The touch screen 108 is a liquid crystal panel configured by overlapping touch sensors. The touch screen 108 detects position information corresponding to the position pressed by the user with a finger or the touch pen 201 and inputs the position information to the CPU 101. That is, the touch screen 108 accepts an instruction input from the user, like the input unit 105.

  Note that data temporarily stored in the RAM 103 can be appropriately stored in the memory cassette 106 in accordance with an instruction input by the user via the input unit 105 or the touch screen 108.

  The NIC 109 is for connecting the information processing apparatus 100 to a computer communication network (not shown) such as the Internet. For example, when the information processing apparatus 100 is wirelessly connected to a LAN (Local Area Network), the NIC 109 is configured by an interface (not shown) compliant with a standard such as IEEE 802.11. In addition, when connecting to the LAN by wire, the NIC 109 conforms to the 10BASE-T / 100BASE-T standard, an analog modem for connecting to the Internet using a telephone line, ISDN (Integrated Services Digital Network). It comprises a modem, an ADSL (Asymmetric Digital Subscriber Line) modem, a cable modem for connecting to the Internet using a cable television line, and an interface (not shown) that mediates between these and the CPU 101.

  It is also possible to obtain current date and time information by connecting to an SNTP server in the Internet via the NIC 109 and acquiring information therefrom. In addition, various network game server devices may be configured and configured to perform the same functions as the SNTP server.

  The sound processing unit 110 converts the sound data read from the memory cassette 106 into an analog sound signal, and outputs the analog sound signal from the speaker 112 connected to the sound processing unit 110. In addition, the sound processing unit 110 generates sound effects and sound data to be generated during the game control under the control of the CPU 101, and outputs sound corresponding to the sound effects and sound data from the speaker 112.

  When the audio data recorded in the memory cassette 106 is MIDI data, the audio processing unit 110 refers to the sound source data included in the audio data and converts the MIDI data into PCM data. If the compressed audio data is in ADPCM format or Ogg Vorbis format, it is expanded and converted to PCM data. The PCM data is subjected to D / A (Digital / Analog) conversion at a timing corresponding to the sampling frequency, and output to the speaker 112 or the like, thereby enabling voice output.

  The audio processing unit 110 performs A / D (Analog / Digital) conversion on the analog signal input from the microphone 111 at an appropriate sampling frequency to generate a PCM format digital signal.

  The RTC 113 is a timekeeping device including a crystal resonator and an oscillation circuit. The RTC 113 is supplied with power from the built-in battery, and continues to operate even when the information processing apparatus 100 is powered off.

  In addition, the information processing apparatus 100 includes a DVD-ROM drive that reads programs and data from a DVD-ROM instead of the memory cassette 106, and the DVD-ROM has the same function as the memory cassette 106. You may make it let. The interface 104 may be configured to read data from an external memory medium other than the memory cassette 106. Alternatively, the information processing apparatus 100 may be configured to perform the same function as the ROM 102, the RAM 103, the memory cassette 106, and the like using a large-capacity external storage device such as a hard disk.

  The increasing unit 304 increases the counter value with the passage of time while the detected position continues to be included in the specific area. The increase unit 304 is realized by the CPU 101, for example.

  The decrease unit 306 decreases the counter value with the lapse of time until the user reaches the initial value while the user is not touching the screen or the detected position is not included in the specific area. The reduction unit 306 is realized by the CPU 101, for example.

  The display unit 301 displays the counter value on the screen while the detected position continues to be included in the specific area.

  When the counter value exceeds the threshold value, the output unit 305 outputs an instruction input from the user. The output unit 305 is realized by the CPU 101, for example.

(Description of display screen)
Here, an image displayed on the touch screen 108 will be described with reference to FIG. An image representing information to be presented to the user is displayed on the touch screen 108. On the other hand, the user refers to the displayed image and performs an operation input necessary for the progress of the game via the touch screen 108.

  FIG. 4 shows an image 400 that accepts an answer “OK” or “Cancel” from the user in response to an inquiry “Are you sure you want to start the game with saved data 1?”. The image 400 includes an area 401, an area 402, an area 403, and an area 404. The image 400 is an image having a size of 256 dots in the X-axis direction and a size of 192 dots in the Y-axis direction. As shown in FIG. 4, it is assumed that the origin O where the X coordinate is 0 and the Y coordinate is 0 is in the lower left corner of the image 400. Hereinafter, the X coordinate and the Y coordinate on the image 400 are collectively referred to as a coordinate as appropriate. In the present embodiment, the description will be made on the assumption that the user answers “OK”.

  In an area 401, an image representing an OK button is displayed. That is, the area 401 is an area to be touched when the user answers “OK”. The region 401 is a region having an X coordinate of 150 to 230 and a Y coordinate of 80 to 100. That is, the coordinates of the four vertices of the region 401 are (150, 80), (230, 80), (150, 100), and (230, 100). The size of the area 401 is 80 × 20.

  In the area 403, an image representing the counter value related to the area 401 among the counter values stored in the storage unit 303 is displayed. The counter value is counted up by the increasing unit 304 while the position detected by the detecting unit 302 is included in the area 401, and is decreased by the decreasing unit 306 while the detected position is not included in the area 401. Count down.

  The image displayed in the area 403 may be any image as long as it is an image representing a counter value. FIG. 4 shows an example in which the image representing the counter value is an image representing a gauge. FIG. 4 shows the counter value corresponding to the total time that the area 401 needs to be touched in order to accept the operation input by the gauge length L0, and the current counter value by the length L1 of the shaded portion of the gauge. In this example, the counter value corresponding to the remaining time that the area 401 needs to be touched until an operation input is accepted is indicated by the length L2 of the white portion of the gauge.

  In the example shown in FIG. 4, (a) L1 = 0 and L2 = L0 in the initial state. (B) While the area 401 is touched, L1 increases and L2 decreases. If the counter value is not 0 while the area 401 is not touched, L1 decreases and L2 increases and (d) If the counter value is 0 while the area 401 is not touched, L1 = 0 and L2 = L0 are maintained, and (e) L1 = L0 and L2 = 0 when an operation input is accepted. Note that L0 is a fixed value, and L0 = L1 + L2. By observing the gauge image displayed in the area 403, the user can know how long the area 401 should be touched.

  FIG. 4 shows a state in which the user is touching the area 401 using the touch pen 201. In the example illustrated in FIG. 4, the coordinates on the image 400 of the detected position (hereinafter referred to as “touch position”. In FIG. 4, the touch position is indicated by C) are the X coordinate and the Y coordinate. Is 90. Therefore, FIG. 4 shows an example in which the touch position is included in the region 401.

  In the area 402, an image representing the Cancel button is displayed. That is, the area 402 is an area to be touched when the user answers “Cancel”.

  In the area 404, an image representing the counter value related to the area 402 among the counter values stored in the storage unit 303 is displayed. The counter value is counted up by the increase unit 304 while the touch position is included in the region 402, and is counted down by the decrease unit 306 while the detected position is not included in the region 402. In the present embodiment, the description is made on the assumption that the specific area to be touched by the user is the area 401, that is, the user answers “OK”. Therefore, it is described that the counter value represented by the image displayed in the area 403 increases or decreases depending on whether or not the touch position is included in the area 401. For this reason, although detailed description of the area 402 and the area 404 is omitted, the counter value related to the area 402 is displayed in the area 404 and the touch position is included in the area 402 as in the areas 401 and 403. The counter value increases while the touch position is out of the area 402 while the counter value decreases.

(Operation of the input reception device)
Next, the operation of the input receiving apparatus 300 according to the present embodiment will be described with reference to the drawings. FIG. 5 is a flowchart showing an input reception process executed by the input reception device 300 according to this embodiment. The input receiving process shown in FIG. 5 is a process executed when the image 400 shown in FIG. 4 is presented to the user and an instruction input is received from the user. That is, the image 400 shown in FIG. 4 is an image displayed on the screen for prompting the user to input an instruction and receiving the instruction input by the user, and is an image presented to the user in the input receiving process shown in FIG. . In the present embodiment, first, a part related to the area 401 and the area 403 will be described on the assumption that the user answers “OK”.

  First, the CPU 101 initializes the counter value stored in the RAM 103 to 0 (step S101). This counter value is a counter value that increases or decreases depending on whether or not the touch position is included in the area 401.

  When the CPU 101 ends the process of step S101, the CPU 101 displays an image representing the OK button in the area 401 that is the specific area (step S102). The CPU 101 displays an image representing the OK button in the area 401 based on the coordinates of the four vertices in the area 401 and the image information representing the OK button read in advance from the memory cassette 106 to the RAM 103.

  When the CPU 101 ends the process of step S102, it displays the counter value stored in the RAM 103 (step S103). The CPU 101 generates a gauge image representing the counter value stored in the RAM 103 and displays the generated gauge image in the area 403. In the present embodiment, the threshold value of the counter value is represented together with the counter value by the gauge image. It is assumed that the threshold value of the counter value has been read from the memory cassette 106 to the RAM 103 in advance.

  CPU101 detects a touch position, after complete | finishing the process of step S103 (step S104). The touch position is a position where the user touches the touch screen 108 using the touch pen 201. The touch position is represented by coordinates on the image 400 and is stored in the RAM 103.

  When the CPU 101 ends the process of step S104, the CPU 101 determines whether or not the touch position detected in step S104 is included in the area 401 that is the specific area (step S105). Specifically, the CPU 101 includes the touch position in the area 401 based on the coordinates of the four vertices of the area 401 stored in the RAM 103 and the coordinates of the touch position stored in the RAM 103. It is determined whether or not.

  When the CPU 101 determines that the touch position is included in the area 401 that is the specific area (step S105: YES), the CPU 101 increments the counter value stored in the RAM 103 (step S106). Specifically, the CPU 101 reads a counter value stored in the RAM 103 and stores a value obtained by adding 1 to the read counter value in the RAM 103 as a counter value.

  When the CPU 101 determines that the touch position is not included in the region 401 that is the specific region (step S105: NO), the CPU 101 decrements the counter value stored in the RAM 103 (step S107). Specifically, the CPU 101 reads a counter value stored in the RAM 103 and stores a value obtained by subtracting 1 from the read counter value in the RAM 103 as a counter value. Note that when the counter value stored in the RAM 103 is 0, no decrement is performed.

  When the CPU 101 finishes the process of incrementing the counter value (step S106) or the process of decrementing the counter value (step S107), the CPU 101 waits until a timer interrupt occurs (step S108). In this embodiment, it is assumed that the timer interrupt is set in advance so as to occur every 10 msec.

  When the CPU 101 ends the process of step S108, the CPU 101 determines whether or not the counter value stored in the RAM 103 exceeds the threshold value stored in the RAM 103 (step S109). In the present embodiment, the threshold is 200, and it is assumed that an operation input is accepted when the region 401 is continuously touched for 200 × 10 ms = 2 seconds.

  When the CPU 101 determines that the counter value does not exceed the threshold value (step S109: NO), the CPU 101 returns the process to step S103. On the other hand, when the CPU 101 determines that the counter value has exceeded the threshold value (step S109: YES), the CPU 101 receives an instruction input (step S110). That is, it is determined that an instruction input requesting an answer “OK” is received from the user and the game is started with the save data 1.

  When the CPU 101 ends the process of step S110, the input reception process ends.

  Here, with reference to FIG. 6, how the counter value changes depending on whether or not the touch position is included in the region 401 at each time will be described.

  FIG. 6 is a diagram showing the relationship between the time elapsed since the start of the input reception process shown in FIG. 5 and the counter value represented by the image displayed in the area 403 in the image 400 shown in FIG. is there. Assume that the initial value of the counter value is 0 and the threshold value of the counter value is c2. Here, (1) the counter value increases while the touch position is included in the area 401, and (2) the counter value decreases while the counter value is not 0 and the touch position is not included in the area 401. (3) While the counter value is 0 and the touch position is not included in the area 401, the counter value is maintained at 0. The change of the counter value in each time zone is shown below.

Since the counter value is 0 and the touch position is not included in the area 401 during the time from t0 to t1, the counter value is maintained at 0.
Since the touch position is included in the area 401 during the time from t1 to t2, the counter value increases from 0 to c1.
Since the counter value is not 0 and the touch position is not included in the area 401 during the time from t2 to t3, the counter value decreases from c1 to 0.
Since the counter value is 0 and the touch position is not included in the area 401 during the time from t3 to t4, the counter value is maintained at 0.
Since the touch position is included in the area 401 between the time t4 and t5, the counter value increases from 0 to c2.
When the time reaches t5, the counter value becomes c2, which is a threshold value, so that an instruction input from the user is accepted, and the input acceptance process ends.

  In the above description of the input reception process, the portion related to the area 401 and the area 403 has been described on the assumption that the user answers “OK”. However, the same process is performed even when the user answers “Cancel”. . That is, in step S101, the counter value that increases or decreases depending on whether or not the touch position is included in the region 402 that is the specific region is initialized to 0. In step S102, an image representing the Cancel button is displayed in the region 402. In step S 103, a gauge image representing the counter value stored in the RAM 103 is generated, and the generated gauge image is displayed in the area 403. In step S104, the touch position is detected. Here, in step S <b> 105, it is determined whether or not the detected touch position is included in the region 402. If it is determined that the touch position is included in the area 402, the counter value stored in the RAM 103 is incremented in step S106. On the other hand, if it is determined that the touch position is not included in the area 402, the counter value stored in the RAM 103 is decremented in step S107. Next, in step S108, the CPU 101 waits until a timer interrupt occurs. In step S109, it is determined whether or not the counter value stored in the RAM 103 exceeds a threshold value. If it is determined that the counter value stored in the RAM 103 exceeds the threshold value, in step S110, an instruction input requesting an answer “Cancel” is received, and the input receiving process ends. On the other hand, if it is determined that the counter value stored in the RAM 103 does not exceed the threshold value, the process returns to step S103.

  According to the input receiving apparatus 300 according to the present embodiment, when the user can stably perform a touch operation such as when a specific area is continuously touched for a certain time or longer, an instruction input from the user is performed. Accepted. For this reason, it is expected that the user's touch operation is improved. On the other hand, when the user cannot perform an accurate touch operation, such as when the user is on a train with great shaking or when the user is walking, an instruction input from the user is not accepted. For this reason, it is expected that “instruction input by the user is prevented in a state where it is difficult to perform a touch operation such as during walking”. Therefore, the user is expected to input an instruction after stopping. In addition, according to the input receiving device 300 according to the present embodiment, an indication of the remaining time that needs to be touched on a specific area until an instruction input from the user is received can be presented to the user with an image representing a gauge. . Therefore, the user can intuitively know the time required to touch by looking at the image representing the gauge.

(Second Embodiment)
The input receiving apparatus 300 of the first embodiment has shown an example in which the position where the specific area is displayed is fixed. However, the input reception device of the present invention may be configured such that the position where the specific area is displayed changes. Hereinafter, although the input reception device 300 according to the second embodiment will be described, description of the same configuration and operation as those of the input reception device 300 according to the first embodiment will be omitted as appropriate.

(Configuration of the input reception device)
The configuration of the input reception device 300 according to the second embodiment is the same as the configuration of the input reception device 300 shown in FIG. The main difference between the input receiving apparatus 300 according to the second embodiment and the input receiving apparatus 300 according to the first embodiment is the operation of the display unit 301. Therefore, the operation of the display unit 301 will be described below.

  The display unit 301 displays an area 401 that is a specific area to be touched by the user on the screen. Here, the display unit 301 moves the place where the region 401 is displayed on the screen while the region 401 continues to be included in the position detected by the detection unit 302. The display unit 301 is realized by the CPU 101 and the image processing unit 107, for example.

(Description of display screen)
Here, an image displayed on the touch screen 108 will be described with reference to FIG.

  FIG. 7 shows an image 410 for allowing the user to answer “OK” or “Cancel” in response to an inquiry “Are you sure you want to start the game with saved data 1?”. The image 410 includes a region 401, a region 402, a region 413, and a region 414. In the present embodiment, the specific area to be touched by the user is assumed to be the area 401.

  In an area 401, an image representing an OK button is displayed. That is, the area 401 is an area to be touched when the user answers “OK”. The size of the area 401 is 80 × 20. Here, while the touch position (the touch position is indicated by C in FIG. 7) continues to be included in the area 401, the position of the area 401 on the image 410 changes. In the example shown in FIG. 7, the region 401 has (50, 50) from the position where the coordinates of the four vertices are (150, 80), (230, 80), (150, 100), (230, 100). ), (130, 50), (50, 70), and (130, 70). Here, the user traces the area 401 so as to continue touching the area 401 in order to accept the operation input. That is, the user moves the pen tip of the touch pen 201 with the movement of the area 401 so that the touch position does not protrude from the area 401 that moves on the image 410.

  In the area 413, an image representing the counter value stored in the storage unit 303 is displayed. FIG. 7 shows an example in which the counter value is represented by an image representing a fraction. FIG. 7 shows a counter value (200) corresponding to the total time that the area 401 needs to be touched until an operation input is accepted by a numerical value displayed in the denominator, and the current counter is expressed by a numerical value displayed in the numerator. An example is shown in which the value (150) is represented. Note that a counter value (200−150 = 50) corresponding to the remaining time that the area 401 needs to be touched until an operation input is accepted is obtained by subtracting the numerical value displayed in the numerator from the numerical value displayed in the denominator. expressed.

  In the area 402, an image representing the Cancel button is displayed. That is, the area 402 is an area to be touched when the user answers “Cancel”.

  In the area 414, an image representing the counter value related to the area 402 among the counter values stored in the storage unit 303 is displayed. The counter value is counted up by the increase unit 304 while the touch position is included in the region 402, and is counted down by the decrease unit 306 while the detected position is not included in the region 402. In the present embodiment, detailed description of the region 402 and the region 414 is omitted, but the counter value related to the region 402 is displayed in the region 414 and the touch position is the region as in the regions 401 and 413. While the position 402 is continuously included in the area 402, the position of the area 402 on the image 410 is changed. While the touch position is included in the area 402, the counter value is increased and the touch position is out of the area 402. , The counter value decreases.

(Operation of the input reception device)
Next, the operation of the input receiving apparatus 300 according to the present embodiment will be described with reference to the drawings. FIG. 8 is a flowchart showing an input reception process executed by the input reception device 300 according to this embodiment. The input reception process shown in FIG. 8 is a process executed when an instruction input is received from the user.

  First, the CPU 101 initializes the counter value stored in the RAM 103 to 0 (step S201). This counter value is a counter value that increases or decreases depending on whether or not the touch position is included in the area 401.

  When the CPU 101 ends the process of step S201, the CPU 101 displays an image representing the OK button in the area 401 that is the specific area (step S202). The CPU 101 displays an image representing the OK button in the area 401 based on the coordinates of the four vertices in the area 401 and the image information representing the OK button read in advance from the memory cassette 106 to the RAM 103. Note that the coordinates of the four vertices of the area 401 stored in the RAM 103 are updated in step S206 described later.

  When the CPU 101 completes the process of step S202, it displays the counter value stored in the RAM 103 (step S203). The CPU 101 generates a fractional image representing the counter value stored in the RAM 103 and the counter value threshold, and displays the generated fractional image in the area 413.

  When the CPU 101 ends the process of step S203, it detects the touch position (step S204). The touch position is represented by coordinates on the image 400 and is stored in the RAM 103.

  When the CPU 101 ends the process of step S204, the CPU 101 determines whether or not the touch position detected in step S204 is included in the area 401 that is the specific area (step S205).

  When the CPU 101 determines that the touch position is included in the region 401 that is the specific region (step S205: YES), the CPU 101 calculates the position of the region 401 that is the specific region on the image 410 (step S206). Here, the position of the area 401, that is, the position of the coordinates of the area 401 is arbitrary. For example, the amount of displacement in the X-axis direction and the amount of displacement in the Y-axis direction are respectively determined by generating random numbers. Alternatively, a table composed of a set of the displacement amount in the X-axis direction (or X-coordinate itself) and the displacement amount in the Y-axis direction (or Y-coordinate itself) is stored in the memory cassette 106 and read out to the RAM 103 as appropriate. It may be used. Note that the position of the region 401 on the image 410 is preferably calculated so as to gradually change over time while the touch position is included in the region 401 that is the specific region. The CPU 101 stores the obtained position of the area 401 in the RAM 103. As described above, in step S <b> 202, the CPU 101 displays an image representing the OK button at the position of the area 401 stored in the RAM 103. That is, while the position of the region 401 on the image 410 is changed in the process of step S206, the position on the image 410 where the image representing the OK button is displayed is moved in the process of step S202.

  When the CPU 101 ends the process of step S206, the CPU 101 increments the counter value stored in the RAM 103 (step S207). Specifically, the CPU 101 reads a counter value stored in the RAM 103 and stores a value obtained by adding 1 to the read counter value in the RAM 103 as a counter value.

  When the CPU 101 determines that the touch position is not included in the region 401 that is the specific region (step S205: NO), the CPU 101 decrements the counter value stored in the RAM 103 (step S208). Specifically, the CPU 101 reads a counter value stored in the RAM 103 and stores a value obtained by subtracting 1 from the read counter value in the RAM 103 as a counter value. Note that when the counter value stored in the RAM 103 is 0, no decrement is performed.

  When the CPU 101 finishes the process of incrementing the counter value (step S207) or the process of decrementing the counter value (step S208), the CPU 101 waits until a timer interrupt occurs (step S209). In the present embodiment, it is assumed that the timer interrupt is set in advance so as to occur every 10 msec.

  When the CPU 101 ends the process of step S108, the CPU 101 determines whether or not the counter value stored in the RAM 103 exceeds the threshold value stored in the RAM 103 (step S210). In the present embodiment, the threshold is 200, and it is assumed that an operation input is accepted when the region 401 is continuously touched for 200 × 10 ms = 2 seconds.

  When the CPU 101 determines that the counter value does not exceed the threshold (step S210: NO), the CPU 101 returns the process to step S202. In step S202, an area 401, which is a specific area, is displayed at the position updated in step S206.

  On the other hand, when the CPU 101 determines that the counter value has exceeded the threshold value (step S210: YES), the CPU 101 receives an instruction input (step S211). That is, it is accepted that an instruction input requesting an answer “OK” is received from the user, and it is determined to start the game with the save data 1.

  When the CPU 101 ends the process of step S211, the CPU 101 ends the input reception process.

  According to the input reception device 300 according to the present embodiment, the position of the specific area on the screen is changed while the detected touch position is included in the specific area. Therefore, it is expected that the user's touch operation is further improved. In addition, it is expected that an instruction input by the user is further prevented in a state where it is difficult to perform a touch operation such as during walking. Further, according to the input receiving apparatus 300 according to the present embodiment, an indication of the remaining time that needs to be touched on a specific area until an instruction input from the user is received can be presented to the user with an image representing a fraction. . Therefore, the user can accurately know the remaining time that needs to be touched by looking at the image representing the fraction.

(Modification)
In the first and second embodiments, the example in which the counter value decreases while the touch position is out of the specific area has been described. However, as shown in FIG. 9, the counter value may be initialized when the touch position deviates from the specific area. In the example shown in FIG. 9, when the touch position deviates from the specific area (when the time reaches t2), the counter value is initialized to 0 immediately. Thereby, it is expected that the user touches the specific area without being distracted for a moment until an operation input is accepted.

  In the first and second embodiments, an example is shown in which the speed at which the counter value increases while the specific area is touched is the same as the speed at which the counter value decreases while the specific area is not touched. It was. However, the increasing speed and the decreasing speed may be different. For example, as shown in FIG. 10, the decreasing speed is made faster than the increasing speed. In the example shown in FIG. 10, the time from t2 to t3 until the counter value decreases from c1 to 0 is shorter than the time from t1 to t2 until the counter value increases from 0 to c1. That is, the speed at which the counter value decreases is faster than the speed at which the counter value increases. Thereby, it is expected that the user touches the specific area without being distracted for a moment until an operation input is accepted.

  In the first and second embodiments, an example is shown in which the counter value is immediately decreased when the touch position deviates from the specific area. However, as shown in FIG. 11, even if the touch position deviates from the specific area, the counter value is not decreased immediately, and the counter value is changed when the state where the touch position deviates from the specific area continues for a predetermined threshold time Tth. You may make it reduce. In FIG. 11, the touch position is not included in the specific area between the time t0 and t1, the time t2 to t6, and the time t7 to t4, and the time is from t1 to t2. The relationship between the time and the counter value in the case where the touch position is included in the specific area during the period between time t6 and t7 and between time t4 and t5 is shown.

Since the counter value is 0 and the touch position is not included in the specific area during the time from t0 to t1, the counter value is maintained at 0.
Since the touch position is included in the specific area between the time t1 and t2, the counter value increases from 0 to c1.
During the time from t2 to t6, the counter value is not 0 and the touch position is not included in the specific area, but the time elapsed from the time (t2) when the touch position departed from the specific area exceeds the threshold time Tth. Therefore, the counter value is maintained at c1.
Since the touch position is included in the specific area between the time t6 and t7, the counter value increases from c1 to c3.
Between time t7 and t8, the counter value is not 0 and the touch position is not included in the specific area, but the time elapsed from the time (t7) when the touch position departed from the specific area exceeds the threshold time Tth. Therefore, the counter value is maintained at c3.
During the time from t8 to t3, the counter value is not 0, the touch position is not included in the specific area, and the time elapsed from the time (t7) when the touch position is out of the specific area exceeds the threshold time Tth. Therefore, the counter value decreases from c3 to 0.
Since the counter value is 0 and the touch position is not included in the specific area from time t3 to t4, the counter value is maintained at 0.
Since the touch position is included in the specific area between time t4 and t5, the counter value increases from 0 to c2.
When the time reaches t5, the operation value is accepted because the counter value is c2.

  Here, referring to FIG. 12, even when the touch position deviates from the specific area, the counter value is not immediately decreased, and the counter value is decremented when the state where the touch position deviates from the specific area continues for a predetermined threshold time Tth. An input reception process for decreasing the number will be described.

  First, the CPU 101 initializes the counter value stored in the RAM 103 to 0 (step S301).

  Next, the CPU 101 initializes a continuation time Tcon that represents a time during which the touch position continues to deviate from the specific area to 0 (step S302). The duration time Tcon is represented by a numerical value with the period in which the timer interrupt occurs as a unit. In other words, the duration Tcon increases by 1 every time a timer interrupt occurs while the touch position continues to deviate from the specific area. On the other hand, the duration Tcon is initialized to 0 when the touch position is included from the specific area. The duration Tcon is assumed to be stored in the RAM 103.

  When the CPU 101 completes the process of step S302, it displays an image representing the OK button in the area 401, which is the specific area (step S303).

  When the CPU 101 ends the process of step S303, it displays the counter value stored in the RAM 103 (step S304).

  CPU101 detects a touch position, after complete | finishing the process of step S304 (step S305).

  When the CPU 101 ends the process of step S305, the CPU 101 determines whether or not the touch position detected in step S305 is included in the area 401 that is the specific area (step S306).

  When the CPU 101 determines that the touch position is included in the area 401 that is the specific area (step S306: YES), the CPU 101 increments the counter value stored in the RAM 103 (step S307), and further sets the duration Tcon. It is cleared to 0 (step S308).

  When the CPU 101 determines that the touch position is not included in the region 401 that is the specific region (step S306: NO), the CPU 101 determines whether or not the duration Tcon exceeds the threshold time Tth (step S309). Here, the threshold time Tth is a delay time until the counter value is decremented after the touch position deviates from the specific area when the touch position deviates from the specific area. Similarly to the duration Tcon, the threshold time Tth is represented by a numerical value in units of a cycle in which a timer interrupt occurs, and is stored in the RAM 103.

  When the CPU 101 determines that the duration time Tcon exceeds the threshold time Tth (step S309: YES), the CPU 101 decrements the counter value stored in the RAM 103 (step S310). However, when the counter value stored in the RAM 103 is 0, the decrement is not performed.

  When the CPU 101 determines that the duration Tcon does not exceed the threshold time Tth (step S309: NO), or when the process of decrementing the counter value (step S310) is completed, the CPU 101 stores it in the RAM 103. The duration time Tcon is increased by 1 (step S311).

  When the CPU 101 completes the process of initializing the duration Tcon to 0 (step S308) or the process of incrementing the duration Tcon by 1 (step S311), the CPU 101 waits until a timer interrupt occurs (step S312).

  When the CPU 101 finishes the process of step S312, it determines whether or not the counter value stored in the RAM 103 exceeds the threshold stored in the RAM 103 (step S313).

  When the CPU 101 determines that the counter value does not exceed the threshold value (step S313: NO), the CPU 101 returns the process to step S304. On the other hand, if the CPU 101 determines that the counter value has exceeded the threshold (step S313: YES), it accepts an instruction input (step S314).

  When the CPU 101 ends the process of step S314, the input reception process ends.

  In this way, by preventing the count value from being decreased immediately after the touch position deviates from the specific area, the user can be encouraged to calm down and continue the touch operation. In other words, according to such a configuration, even if the touch position temporarily deviates from the specific area for some time, there is a grace period until the counter value decreases, so the user can not touch the touch position. Expected to return to a specific area.

  Alternatively, the counter value may be reset to 0 when the touch position is out of the specific area for a predetermined threshold time Tth. Even in this case, since there is a grace period until the counter value is reset to 0, it is expected that the touch position is returned to the specific area without being struck by the user.

  In the first embodiment, the counter value is represented by an image representing a gauge, and in the second embodiment, the counter value is represented by an image representing a fraction. However, the method of presenting the counter value to the user is arbitrary. For example, the image is displayed so that the increase / decrease in the counter value can be determined by the change in the color, size, shape, etc.

  In the first and second embodiments, an example is shown in which an image representing a counter value is displayed in a region different from the specific region. However, an image representing the counter value may be displayed in the specific area. For example, in the first embodiment, the color of the image representing the OK button displayed in the area 401 is changed according to the counter value. This eliminates the need to provide an area for displaying an image representing the counter value separately from the specific area.

  In the second embodiment, the example in which the position of the specific area on the screen changes while the specific area is being touched has been described. However, instead of changing the position of the specific area on the screen, the size of the specific area may be reduced. When the size of the specific area changes in this way, the user carefully monitors the specific area and carefully adjusts the touch position so as not to deviate from the specific area. Therefore, the user can be trained to perform the touch operation accurately, and the touch operation by the user who cannot perform the stable touch operation can be suppressed.

  In the first and second embodiments, the example is shown in which the image displayed in the specific area is an image representing a button. However, the image displayed in the specific area may be any image as long as it can present to the user that the area should be touch-operated. For example, an image representing a character, a character string, a symbol, or an item can be displayed in a specific area.

  In the first and second embodiments, the example in which the counter value increases or decreases each time a timer interrupt occurs is shown. However, the counter value may be increased or decreased every screen update cycle (typically 1/60 sec).

  As described above, according to the present invention, when receiving an instruction input based on a touch operation, an input receiving apparatus, an input receiving method, and an input receiving method that are suitable for preventing an erroneous input are realized by a computer.
