[Configuration of information processing device]
FIG. 2 is a diagram showing an external configuration of an embodiment of an information processing apparatus to which the present invention is applied. An information processing apparatus to which the present invention is applied is, for example, a personal computer. In the following description, a case where the present invention is applied to a personal computer will be described as an example.

  The personal computer 1 includes a main body 2 and a display unit 3. The main body 2 is provided with a keyboard 4 for inputting characters and numbers. The main body 2 is connected to a mouse 11. Here, the description will be continued assuming that the mouse 11 is connected, but a track pad or the like may be used instead of the mouse 11.

  The display unit 3 includes an LCD (Liquid Crystal Display) 21. Further, the LCD 21 is equipped with a so-called touch panel 22 that outputs a position signal corresponding to a position instructed by a user's contact operation.

  The touch panel 22 is made of a transparent material such as glass or resin, and the user can view an image displayed on the LCD 21 formed inside the touch panel 22 through the touch panel 22.

  As described above, the personal computer 1 illustrated in FIG. 2 is configured to include the keyboard 4, the mouse 11, and the touch panel 22 as input devices.

  FIG. 3 is a diagram illustrating an internal configuration example of the personal computer 1. A CPU (Central Processing Unit) 51 of the personal computer 1 executes various processes in accordance with a program stored in a ROM (Read Only Memory) 52 or a storage unit 58. A RAM (Random Access Memory) 53 appropriately stores programs executed by the CPU 51 and data. These CPU 51, ROM 52, and RAM 53 are connected to each other by a bus 54.

  An input / output interface 55 is also connected to the CPU 51 via the bus 54. Connected to the input / output interface 55 are an input unit 56 including a keyboard 4, a mouse 11, a touch panel 22, a microphone, and the like, an LCD 21, and an output unit 57 including a speaker. The CPU 51 executes various processes in response to commands input from the input unit 56. Then, the CPU 51 outputs the processing result to the output unit 57.

  The storage unit 58 connected to the input / output interface 55 includes, for example, a hard disk, and stores programs executed by the CPU 51 and various data. The communication unit 59 communicates with an external device via a network such as the Internet or a local area network. A program may be acquired via the communication unit 59 and stored in the storage unit 58.

  The drive 60 connected to the input / output interface 55 drives a removable medium 61 such as a magnetic disk, an optical disk, a magneto-optical disk, or a semiconductor memory, and drives the programs and data recorded therein. Get etc. The acquired program and data are transferred to and stored in the storage unit 58 as necessary.

  FIG. 4 is a functional block diagram showing functions of the personal computer 1. Each function shown in FIG. 4 is realized by the operation of each unit constituting the personal computer 1 shown in FIG.

  Data from different input devices of the mouse 11 and the touch panel 22 is supplied to the coordinate storage unit 80 through a common interface. Here, since the process described later is a process related to coordinates, the following description will be continued assuming that the mouse 11 and the touch panel 22 for inputting data related to coordinates constitute the input unit 56. The data relating to the coordinates is, for example, the coordinate value of the movement destination when a cursor (not shown) displayed on the LCD 21 is moved.

  Data relating to coordinates from the input unit 56 is supplied to the coordinate storage unit 80 and temporarily stored. The data stored in the coordinate storage unit 80 is supplied to the movement amount calculation unit 81. The movement amount calculation unit 81 calculates the movement amount using the coordinate values input from the mouse 11 or the touch panel 22, that is, from the data stored in the coordinate storage unit 80. The movement amount is a distance from a first position at which the cursor is located to a second position designated by the mouse 11 or the touch panel 22 at a predetermined time, for example.

  The movement amount calculated by the movement amount calculation unit 81 is supplied to and stored in the movement amount storage unit 82. Further, the movement amount calculated by the movement amount calculation unit 81 is also supplied to the difference value calculation unit 83. The difference value calculation unit 83 calculates the difference in the movement amount, supplies the absolute value of the calculated difference value to the difference value storage unit 84, and stores it.

  The difference value stored in the difference value storage unit 84 is supplied to the addition value calculation unit 85. The addition value calculation unit 85 adds difference values for a predetermined time (a predetermined number of difference values), and supplies the addition value to the addition value storage unit 86 for storage.

  The movement amount stored in the movement amount storage unit 82 is supplied to the destination movement amount calculation unit 87. The destination movement amount calculation unit 87 adds movement amounts for a predetermined time (a predetermined number of movement amounts), and sets the added value as the destination movement amount. The destination movement amount is the result of estimating the movement amount to the destination coordinates that the user will instruct as the movement destination of the cursor when the cursor is moved by operating the mouse 11 or the touch panel 22. However, it is not necessary to estimate accurately, and is a value used as a threshold value when a determination process described later is executed.

  The destination movement amount calculated by the destination movement amount calculation unit 87 is supplied to the input device determination unit 88. The input device determination unit 88 is also supplied with the addition value from the addition value storage unit 86. The input device determination unit 88 determines the input device that has input the coordinate data by comparing the supplied destination movement amount with the added value. That is, in this case, it is determined whether the coordinate data is input from the mouse 11 or the coordinate data is input from the touch panel 22.

  Each storage unit of the coordinate storage unit 80, the movement amount storage unit 82, the difference value storage unit 84, and the addition value storage unit 86 includes, for example, the RAM 53 and / or the storage unit 58 (FIG. 3). These storage units may be realized by using a predetermined storage area in common, or may be realized by providing separate storage areas.

  The movement amount calculation unit 81, the difference value calculation unit 83, the addition value calculation unit 85, the destination movement amount calculation unit 87, and the input device determination unit 88 are each processed by the CPU 51 (FIG. 3) based on a predetermined program. It is a function realized by executing.

  Processing for determining the input device that has input such data will be described with reference to the flowcharts of FIGS.

[About processing related to input device judgment]
A process when coordinate data is input to the personal computer 1 by the mouse 11 or the touch panel 22 will be described with reference to the flowchart of FIG.

  In step S11, coordinate data is acquired by operating the mouse 11 or the touch panel 22 by the user. In this case, the operation of the mouse 11 means that a cursor (not shown) displayed on the LCD 21 is moved by moving the mouse 11. In addition, the touch panel 22 being operated in this case means that the touch panel 22 is touched by the user.

  In step S11, the coordinate data input to the input unit 56 is stored in the coordinate storage unit 80 in step S12. Even when coordinate data is not supplied from the input unit 56, the coordinate storage unit 80 stores a plurality of coordinate data acquired within a predetermined time because it is necessary to know the position of the cursor at that time. ing. In other words, the coordinate storage unit 80 stores the latest, for example, 10 coordinate data, and when new coordinate data is supplied, the oldest coordinate data is deleted and new coordinate data is stored. .

  As described above, since the mouse 11 and the touch panel 22 are integrated into a common interface, the coordinate data acquired by operating the mouse 11 is also the coordinate acquired by operating the touch panel 22. The data is also supplied and stored in the coordinate storage unit 80 via a common interface without distinction.

  When the coordinate data is stored in the coordinate storage unit 80 in this way, an input device determination process is executed in step S13. The input device determination process executed in step S13 will be described later with reference to the flowchart of FIG.

  In step S14, coordinate values are returned. In the input device determination process in step S13, it is determined whether the mouse 11 is operated or the touch panel 22 is operated, a process based on the determination result is performed, and a coordinate value is calculated. In step S14, the coordinate values calculated as a result of the process in step S13 are supplied to other parts not shown in FIG.

  The input device determination process executed in step S13 will be described with reference to the flowchart of FIG.

  In step S31, the movement amount for each TIC is calculated. Here, TIC is a unit indicating the timing at which coordinate data is supplied, and coordinate data is supplied from the input unit 56 to the coordinate storage unit 80 for each TIC. This coordinate data is a coordinate where a cursor (not shown) displayed on the LCD 21 is located.

  In step S <b> 31, the movement amount calculation unit 81 calculates the movement amount using the coordinate data stored in the coordinate storage unit 80. That is, in this case, the distance that the cursor has moved during 1 TIC is obtained.

  For example, if the cursor is positioned at coordinates (x1, y1) at a predetermined time and the cursor is moved to coordinates (x2, y2) by operating the mouse 11 or touch panel 22 after 1 TIC, , The distance from the coordinates (x1, y1) to the coordinates (x2, y2) is obtained. For example, in this case, the movement amount is calculated by taking the square root of the sum of the square of (x2-x1) and the square of (y2-y1).

  The movement amount calculated by the movement amount calculation unit 81 is stored in the movement amount storage unit 82 in step S82. In the processing described later, the movement amount for 3 TIC is used to calculate the destination movement amount, so that the movement amount storage unit 82 stores at least the movement amount for the latest 3 TIC.

  Here, the description will be continued assuming that the amount of movement for 3 TIC is used and the processing is performed, but the amount is not limited to 3 TIC. Further, as will be described later, the difference value and the like are processed using 3 TICs, but the process is not limited to 3 TICs. That is, processing is performed using a plurality of movement amounts and difference values that are continuous in time.

  In step S33, the difference value calculation unit 83 calculates a difference value. The difference value calculation unit 83 calculates a difference between the movement amount calculated by the movement amount calculation unit 81 and the movement amount supplied at a time point one TIC before the movement amount, and calculates a difference value.

  The calculated difference value is supplied to and stored in the difference value storage unit 84 in step S34. The difference value storage unit 84 stores difference values for a plurality of TICs.

  In step S <b> 35, the addition value calculation unit 85 adds the difference values for 3 TIC and calculates the addition value. The addition value calculation unit 85 reads the difference value for the latest 3 TIC stored in the difference value storage unit 84, adds the read difference value for 3 TIC, and calculates the addition value. The added value of the difference values for 3 TIC calculated by the added value calculating unit 85 (hereinafter simply referred to as an added value) is stored in the added value storage unit 86 in step S36.

  In step S37, the destination movement amount calculation unit 87 calculates an addition value of the movement amount for 3 TIC. The added value of the movement amount for 3 TICs is estimated as the movement amount to the destination where the user wants to move the cursor, and is set as the destination movement amount.

  In step S <b> 38, the input device determination unit 88 compares the addition value of the difference values for 3 TIC stored in the addition value storage unit 86 with the destination movement amount set by the destination movement amount calculation unit 87. . In step S39, it is determined whether or not the added value is larger than the destination movement amount.

  If it is determined in step S39 that the added value is larger than the destination movement amount, the process proceeds to step S40, and it is determined that the input is from the touch panel 22. In step S41, a coordinate conversion process is executed. The coordinate conversion process is performed, for example, when the screen is enlarged and displayed as described with reference to FIGS. 1A and 1B.

  For example, as shown in FIG. 1A, when the screen is enlarged and displayed twice, coordinate conversion is performed by dividing the movement amount by two.

  On the other hand, if it is determined in step S39 that the added value is smaller than the destination movement amount, the process proceeds to step S42. In step S42, it is determined that the input is from the mouse 11. When it is determined that the input is from the mouse 11, the coordinate conversion process is not performed.

  In this way, which input device is used is determined, and processing based on the determination is performed. Here, although it has been described that the coordinate conversion process is executed when it is determined that the input is from the touch panel 22, other processes may be executed.

  That is, by applying the present invention, it is possible to distinguish between when the mouse 11 is operated and when the touch panel 22 is operated, so that the touch panel 22 is operated when the mouse 11 is operated. It is possible to execute a different process depending on the time.

  With reference to a specific example, the input device determination processing described with reference to the flowchart of FIG. 6 will be further described.

  FIG. 7 shows an example of a locus of cursor movement from a predetermined position to a target position by the user when the mouse 11 is operated. From time t1 to time t3, the cursor was located at point P1. Note that the interval between each time, for example, the interval from time t1 to time t2 is 1 TIC.

  By operating the mouse 11 at the time t3, the cursor was moved to the point P2 at the time t4. Further, the mouse 11 was operated, and the cursor was moved to point P3 at time t5 and to point P4 at time t6.

  When the user operates the mouse 11 to move the cursor from point P1 to point P4, the cursor is moved from time t3 to time t6 (over 3 TIC). The longer the distance you move the cursor, the longer it will take. In other words, when the cursor is moved by operating the mouse 11, the cursor moves gradually and is not a rapid movement that occurs when a touch panel 22 described later is operated.

  FIG. 8 is a graph showing the relationship between the movement amount and the destination movement amount when the cursor is moved as shown in FIG. In the graph shown in FIG. 8, the X axis indicates the elapsed time, and the Y axis indicates the movement amount or the destination movement amount. In FIG. 8, the bar graph represents the movement amount, and the line graph represents the destination movement amount.

  When the flowchart of FIG. 6 is executed at each of the times t1, t2, and t3, the movement amount calculated by the movement amount calculation unit 81 and stored in the movement amount storage unit 82 in the processing in steps S31 and S32. Is 0.

  By repeating the same processing from time t4 to time t8, a movement amount of 50 at time t4, 52 at time t5, 39 at time t6, 0 at time t7, and 0 at time t8 is calculated. And stored in the movement amount storage unit 82.

  Since the destination movement amount is calculated by adding the movement amounts for 3 TIC stored in the movement amount storage unit 82 in this way, the numerical value transition as shown by the line graph in FIG. 8 is obtained. .

  That is, when the flowchart of FIG. 6 is executed at each of times t1, t2, and t3, it is calculated by the destination movement amount calculation unit 87 and set as the destination movement amount in the processes in steps S37 and S38. The value is 0. At time t4, the movement amount for 3 TIC at time t2, time t3, and time t4 is added, so a value of 50 (= 0 + 0 + 50) is calculated and set as the destination movement amount.

  By repeating the same processing from time t5 to time t8, 102 (= 0 + 50 + 52) at time t5, 141 (= 50 + 52 + 39) at time t6, 91 (= 52 + 39 + 0) at time t7, and 39 at time t8. A value such as (= 39 + 0 + 0) is calculated and set as the destination movement amount.

  FIG. 9 shows the added value of the difference value and the difference value for 3 TIC when the cursor is moved as shown in FIG. 7 and the movement amount and the destination movement amount as shown in FIG. 8 are calculated. It is the graph which showed the relationship. In the graph shown in FIG. 9, the X-axis indicates elapsed time, and the Y-axis indicates a difference value or an added value of 3 TIC difference values. Moreover, in FIG. 9, a bar graph represents a difference value, and a line graph represents an added value.

  When the flowchart of FIG. 6 is executed at each of the times t1, t2, and t3, the amount of movement calculated by the difference value calculation unit 83 and stored in the difference value storage unit 84 in the processing in steps S33 and S34. Is 0. The difference value is an absolute value of the difference in movement amount.

  By repeating the same processing from time t4 to t8, difference values such as 50 at time t4, 2 at time t5, 13 at time t6, 39 at time t7, and 0 at time t8 are calculated. And stored in the difference value storage unit 84.

  Since the addition value is calculated by adding the difference values for 3 TICs stored in the difference value storage unit 84 in this way, the value transitions as shown by the line graph in FIG.

  That is, when the flowchart of FIG. 6 is executed at each of the times t1, t2, and t3, it is calculated by the addition value calculation unit 85 and stored in the addition value storage unit 86 in the processes in steps S35 and S36. The value is 0. At time t4, since the difference value at time t2, time t3, and time t4 is added, a value of 50 (= 0 + 0 + 50) is calculated and stored.

  By repeating the same processing from time t5 to t8, 52 (= 0 + 50 + 2) at time t5, 65 (= 50 + 2 + 13) at time t6, 54 (= 2 + 13 + 39) at time t7, and 52 at time t8. An added value such as (= 13 + 39 + 0) is calculated and stored.

  Using the destination movement amount and the added value calculated in this way, the input device determination unit 88 determines the input device operated at the time of data input.

  FIG. 10 is a graph showing the relationship between two values used when the input device determining unit 88 determines an input device, that is, a graph showing the relationship between the destination movement amount and the added value. In the graph shown in FIG. 10, the X axis indicates the elapsed time, and the Y axis indicates the destination movement amount or the added value. In FIG. 10, a bar graph represents an added value, and a line graph represents a destination movement amount.

In steps S38 and S39 (FIG. 6), the input device determination unit 88 determines whether or not the added value is larger than the destination movement amount. to decide. For example, referring to FIG. 10, at each time from time t1 to time t7,
(Added value of difference values for 3 TIC) <(destination movement amount)
Therefore, it is determined that the input device is the mouse 11.

  Thus, when the mouse 11 is operated, it is determined that the input device is the mouse 11.

  Next, a description will be given of when the touch panel 22 is operated.

  FIG. 11 shows an example of a locus of cursor movement from a predetermined position to a target position by the user by operating the touch panel 22. From time t1 to time t3, the cursor was located at point P1. Note that the interval between each time, for example, the interval from time t1 to time t2 is 1 TIC.

  By operating the touch panel 22 at time t3, the cursor was moved to point P2 at time t4. Further, the touch panel 22 was operated, and the cursor was moved to point P3 at time t5 and to point P4 at time t6.

  In this case, the movement destination of the cursor intended by the user is considered to be one of the points P2 to P4, but the points P2 to P4 are only touched when the touch panel 22 is touched. As a result of the user intentionally instructing a fine movement, it is considered that the user is not instructed at a different time. Accordingly, here, it is assumed that the point designated by the user as the destination is the point P2.

  When the user operates the touch panel 22 to move the cursor from the point P1 to the point P2, the cursor is moved from time t3 to time t4 (at 1 TIC). Even if the distance to move the cursor is long, when the cursor is moved by the operation of the touch panel 22, it can be ended by one operation (contact). In other words, when the cursor is moved by operating the touch panel 22, the cursor may be suddenly moved to a position away from the cursor, and gradually moved as when the mouse 11 described above is operated. Not only when.

  As described above, the mouse 11 and the touch panel 22 have different characteristics even if they are similarly used as input devices. That is, when the mouse 11 is operated and the cursor is moved, the coordinates of the cursor are continuously changed. However, when the touch panel 22 is operated and the cursor is moved, the coordinates of the cursor are not continuously changed. Yes (may change abruptly (discretely)).

  If the processing of the flowchart as shown in FIG. 6 is executed using such a difference for each input device, the input device used at the time of data input can be determined.

  FIG. 12 is a graph of the relationship between the movement amount and the destination movement amount when the cursor is moved as shown in FIG. In the graph shown in FIG. 12, the X axis indicates the elapsed time, and the Y axis indicates the movement amount or the destination movement amount. In FIG. 12, a bar graph represents the amount of movement, and a line graph represents the amount of destination movement.

  When the flowchart of FIG. 6 is executed at each of the times t1, t2, and t3, the movement amount calculated by the movement amount calculation unit 81 and stored in the movement amount storage unit 82 in the processing in steps S31 and S32. Is 0.

  By repeating the same processing from time t4 to time t8, a movement amount such as 145 at time t4, 7 at time t5, 8 at time t6, 0 at time t7, and 0 at time t8 is calculated. And stored in the movement amount storage unit 82.

  Since the destination movement amount is calculated by adding the movement amounts for 3 TICs stored in the movement amount storage unit 82 in this way, the numerical value transition as shown by the line graph in FIG. 12 is obtained. .

  That is, when the flowchart of FIG. 6 is executed at each of times t1, t2, and t3, it is calculated by the destination movement amount calculation unit 87 and set as the destination movement amount in the processes in steps S37 and S38. The value is 0. At time t4, the amount of movement of 3 TIC at time t2, time t3, and time t4 is added, so a value of 145 (= 0 + 0 + 145) is calculated and set as the destination movement amount.

  By repeating the same processing from time t5 to time t8, 152 (= 0 + 145 + 7) at time t5, 160 (= 145 + 7 + 8) at time t6, 15 (= 7 + 8 + 0) at time t7, and 8 at time t8. A value such as (= 8 + 0 + 0) is calculated and set as the destination movement amount.

  FIG. 13 shows the added value of the difference value and the difference value for 3 TIC when the cursor is moved as shown in FIG. 11 and the movement amount and the destination movement amount as shown in FIG. 12 are calculated. It is the graph which showed the relationship. In the graph shown in FIG. 13, the X-axis indicates elapsed time, and the Y-axis indicates a difference value or an addition value of 3 TIC difference values. In FIG. 13, a bar graph represents a difference value, and a line graph represents an added value.

  When the flowchart of FIG. 6 is executed at each of the times t1, t2, and t3, the amount of movement calculated by the difference value calculation unit 83 and stored in the difference value storage unit 84 in the processing in steps S33 and S34. Is 0. The difference value is an absolute value of the difference in movement amount.

  By repeating the same processing from time t4 to t8, difference values such as 145 at time t4, 138 at time t5, 1 at time t6, 8 at time t7, and 0 at time t8 are calculated. And stored in the difference value storage unit 84.

  Since the addition value is calculated by adding the difference values for 3 TICs stored in the difference value storage unit 84 in this way, the value transitions as shown by the line graph in FIG.

  That is, when the flowchart of FIG. 6 is executed at each of the times t1, t2, and t3, it is calculated by the addition value calculation unit 85 and stored in the addition value storage unit 86 in the processes in steps S35 and S36. The value is 0. At time t4, the difference value at time t2, time t3, and time t4 is added, so a value of 145 (= 0 + 0 + 145) is calculated and stored.

  By repeating the same processing from time t5 to time t8, 283 (= 0 + 145 + 138) at time t5, 284 (= 145 + 138 + 1) at time t6, 147 (= 138 + 1 + 8) at time t7, and 9 at time t8. An added value such as (= 1 + 8 + 0) is calculated and stored.

  Using the destination movement amount and the added value calculated in this way, the input device determination unit 88 determines the input device operated at the time of data input.

  FIG. 14 is a graph showing a relationship between two values used when the input device determination unit 88 determines an input device, that is, a graph showing a relationship between the destination movement amount and the added value. In the graph shown in FIG. 14, the X axis indicates the elapsed time, and the Y axis indicates the destination movement amount or the added value. In FIG. 14, the bar graph represents the added value, and the line graph represents the destination movement amount.

In steps S38 and S39 (FIG. 6), the input device determination unit 88 determines whether or not the added value is larger than the destination movement amount. to decide. For example, referring to FIG. 14, at times t5 to t8,
(Added value of difference values for 3 TIC)> (destination movement amount)
Therefore, it is determined that the input device is the touch panel 22.

  Thus, when the touch panel 22 is operated, it is determined that the input device is the touch panel 22.

  As described above, when a plurality of input devices are connected, by determining which of the connected input devices the input device that has input data is, the determination result is obtained. Based on this, it is possible to execute processing specialized for the input device.

  In addition, since it is possible to determine the input device, it is possible to cause the user to execute processing specialized for the input device without performing a special operation such as selection of the input device. The number of steps can be reduced. Therefore, usability can be improved.

  When the processing related to the determination of the input device described above is executed by software, the software may be incorporated in an OS (Operating System) or may be incorporated in a predetermined application. Also good. When it is incorporated in a predetermined application, the input device is determined, and the process based on the determination result can be a process specialized for the application.
