Description

Information processing system, information processing apparatus, method, and program

There is a Microsoft tablet type personal computer in the processing of user input by pen touch to the information processing apparatus (Non-patent Document 1). This is a structure that combines a pen-type device for indicating the position on the screen and a plate-shaped device for detecting the position. Position designation by the mouse is based on the current mouse cursor position. In contrast to the relative designation, the tablet is suitable for detailed work because the absolute position is designated on the plate corresponding to the screen.

Also, as a technique similar to this, a technique of imitating a mouse or classifying pen / user input in combination with other methods is disclosed (Patent Document 1, Patent Document 2, and Patent Document 3).

These technologies use the concept of timeout to classify user input. For example, if there is no input from the user or the network within a set time, the computer performs a different operation.

There is also a technique that uses spatial information to classify user input. This technique determines whether or not a user input has occurred within or outside a predetermined determination area. Furthermore, a technique for gradually expanding a determination area for determining user input has been proposed (Patent Document 4).

Embodiments of the present invention will be described.

In the information processing system such as a digitizer, the present invention determines processing (click, drag, etc.) executed by pen-down, pen-up, movement, etc. of the input pen with respect to the input surface (hereinafter collectively referred to as an event). The determination region to be monotonously decreased as time elapses.

A typical example of the present invention will be described with reference to FIG. FIG. 1 is a diagram schematically showing a determination area on an input surface such as a digitizer, where a solid line indicates a boundary of a determination area of a maximum size, and a dotted line indicates a boundary of a determination area after a predetermined time has elapsed. Show.

The judgment area is generated by a predetermined event (start event), and the maximum size when it occurs. The size of the determination area monotonously decreases until the timeout when the determination area disappears. Here, considering a case where the pen is lowered on the input surface, a determination region including a position where the pen is lowered (start event) is generated. The determination area monotonously decreases until timeout and disappears, but if the pen is raised in the determination area before disappearance, it is determined that the click is made. In addition, if the pen is moved outside the determination area that monotonously decreases without being pen-up after the pen-down, it is determined as a drag.

Note that it is also possible to use pen-up as a start event, position the determination area by pen-up, and generate the determination area by pen-up. The reason is that since the pointer or the like follows the pen position in the pen-down state, the position where the pointer is finally placed, that is, the pen-up position is considered to be the position that the user is trying to select. Further, by doing in this way, it is possible to determine the pen-down following the pen-up in the determination area by the pen-up.

As described above, the determination area for determining the process to be executed according to the event is monotonously decreased as time elapses, so that the determination area is monotonously decreased as compared with the technology in which the determination area does not change as time elapses. In addition, it is possible to quickly determine the processing due to the event, and to obtain a more natural operation feeling.

Furthermore, since the judgment area can be generated continuously according to the current state, a continuous operation similar to a mouse operation such as a click or double click after moving the pointer is uncomfortable. Can be done without.

Hereinafter, specific embodiments will be described with reference to the drawings.
<First Embodiment>
FIG. 2 is a block diagram illustrating the configuration of the information processing system showing the embodiment of the present invention. In the present embodiment, an example is shown in which the display and the digitizer are integrated into a small size, for example, a mobile computer device. However, the present invention can also be applied to an information processing system in which the display and the digitizer are separated. Not too long.

It is also possible to configure the information processing system by dividing the client terminal used by the user and the server like a thin client.

In FIG. 2, reference numeral 1 denotes an information processing system, which includes a CPU 2 that executes various data processing based on a data processing program stored in a program ROM 3, and the CPU 1 controls each connected device. The RAM 4 functions as a main memory, work area, and the like for the CPU 2.

5 is an input control unit that controls input from the digitizer 10.

6 is a display that is integrated with the digitizer 10.

The digitizer 10 includes a digitizer control unit 11, a position detection unit 12, an input surface (operation area) 13, and a display unit 14.

In the digitizer 10, the position detection unit 12 detects the coordinates indicated by the user on the input surface 13 using the input pen 20, and sends the read coordinates to the digitizer control unit 11. In the present embodiment, it is assumed that the input surface 13 is installed on the screen of the display 6. Note that the present invention can be applied without using the input pen 20, but in that case, the position detection unit 12 can detect the coordinates of the position directly touched by the user's finger or the like on the input surface 13. To do.

The screen displayed on the display 6 and the input surface 13 will be described with reference to FIG.

FIG. 3 is a diagram for explaining an image displayed on the display screen of the display 6 and the input surface 13 installed on the display screen.

In FIG. 3, 30 is a display screen. An input surface (operation area) 13 of the digitizer 10 is provided on the display screen 30. Reference numeral 31 denotes a pointing position, which is a position where the user pens down with the input pen 20. 32 is a pointer.

33 is a trajectory, which is a trajectory drawn by the user with the input pen 20, and the pointer 32 moves along this trajectory. In the present embodiment, the trajectory 33 is not displayed, but is drawn for convenience of explanation, but may be displayed. Reference numeral 34 denotes an icon (object). The user moves the pointer by moving the input pen 20 down, up, or moves, and causes the icon 34 to execute predetermined processing such as click, double click, and drag.

Next, control of the determination area for determining processing such as click, double click, and drag due to events such as pen down, pen up, and movement of the input pen 20 will be described.

The judgment area is controlled by the digitizer control unit 11. The digitizer control unit 11 generates a determination area having a predetermined size including the start event detection position, starting from the start event. The determination area has a maximum size when it is generated and linearly decreases in size until a set timeout (determination area disappears). FIG. 4 is a diagram schematically showing the determination area 40 on the input surface 13, where the solid line indicates the boundary line of the determination area of the maximum size, and the dotted line indicates the boundary line of the determination area after a predetermined time has elapsed. Yes. In the present embodiment, the size of the determination region is linearly reduced. However, the size of the determination region is not limited to this, and can be changed as long as the effect of the present invention is produced.

The digitizer control unit 11 determines whether the next event detected by the position detection unit 12 has occurred inside or outside the determination region 40, and outputs the result to the input control unit 5.

The input control unit 5 sends the result to the CPU 2, and the CPU 2 performs predetermined processing such as click, double click, and drag based on the result.

Next, the operation of the information processing apparatus 1 will be described with reference to FIGS. In FIG. 6, for easy understanding, the size of the determination region is expressed in one dimension, the vertical axis is the size of the determination region, and the horizontal axis is time.

First, the position detection unit 12 detects an event (pen down, pen up, movement) (Step 100), and detects the position and time of the event (Step 101, 102).

Next, the digitizer control unit 11 determines whether the event is a start event or a next event (Step 103). This determination is made based on whether a determination area is generated. If it is a start event, the digitizer control unit 11 stores the event and generates a determination area (Steps 104 and 105). Thereafter, the determination area is linearly decreased until the set timeout (Step 106). Also, the digitizer control unit 11 stores that the determination area has been generated.

On the other hand, if it is the next event, the digitizer control unit 11 determines whether the next event has occurred within the determination region or has occurred based on the coordinate position of the detected event (Step 107). . Then, the determination result is transmitted to the CPU 2 via the input control unit 5.

If the event has occurred within the determination area, the CPU 2 performs process A (Step 108. If the next event has occurred outside the determination area, the CPU 2 performs process B (Step 109). .

Next, the operation of the information processing apparatus 1 using a specific example will be described.
(1) Movement of Pointer FIG. 7 is a diagram for explaining movement of the pointer. In FIG. 7, for easy understanding, the determination region is expressed in one dimension, the vertical axis is the size of the determination region, and the horizontal axis is time. In the figure, a white circle with D indicates a pen-down by the input pen 20, a white circle with U indicates a pen-up by the input pen 20, and a solid line indicates the input pen 20. The movement is shown while being in contact with the input surface 13.

First, when the user pens down the input pen 20 with respect to the pointer displayed on the input surface 13 (start event), a determination area of a predetermined size is generated around the pen down position. The judgment area decreases linearly until timeout.

The user starts moving (next event) with the input pen 20 in contact with the input surface 13, and when the detected position of the input pen 20 is out of the determination area from the determination area, the pointer movement process is performed. And the pointer movement display process is executed.

In the present embodiment, since the determination area is linearly decreased, the pointing position due to the movement of the input pen 20 quickly goes out of the determination area compared to the case where the determination area is not decreased, so that the determination process is accelerated. Can be natural operation.
(2) Clicking after moving the pointer FIG. 8 is a diagram for explaining the clicking. As in FIG. 7, FIG. 8 also represents the size of the determination region in one dimension, the vertical axis represents the size of the determination region, and the horizontal axis represents time in order to facilitate understanding. In the figure, a white circle with D indicates a pen-down by the input pen 20, a white circle with U indicates a pen-up by the input pen 20, and a solid line indicates the input pen 20. A movement in a state where the input surface 13 is brought into contact is shown. In the figure, a hatched circle with D indicates that the left button of the mouse is down, and a hatched circle with U indicates that the left button of the mouse is up. Is shown.

In the following explanation, after moving the pointer or after dragging an icon, taking into account a predetermined click or double click, the position of the first pen up after the pointer movement or after dragging is stored, Thereafter, the determination area (area) generated by pen-up is generated with the stored pen-up position as the center position. On the other hand, the center position of the determination area (area) generated by pen-down is the position of each pen-down.

First, when the user moves up the input pen 20 after moving the pointer, the contact position on the input surface 13 of the last input pen 20 is stored as a pen-up position, and a determination area (predetermined size) centered on that position. Area 1) is generated. The determination area (area 1) decreases linearly until timeout.

When the input pen 20 is pen-down, the pen-down position is detected, and it is determined whether this position is within the determination area (area 1). If it is within the determination area (area 1), it is determined that the object such as an icon has been penned down.

Subsequently, by the pen down, a determination area (area 2) having a predetermined size is generated around the pen down position. The determination area (area 2) decreases linearly until timeout.

When the input pen 20 is pen-up within the determination area (area 2), it is determined that the pen is up with respect to an object such as an icon. In addition, a pen-up generates a determination area (area 3) having a predetermined size centering on the position of the first pen-up after the stored pointer movement. The determination area (area 3) decreases linearly until timeout. Then, if there is no event in the determination area (timeout 3) until the determination area (area 3) times out, it is determined to be a click.

In the above description, the size of the determination area (area 1 and area 3) due to pen-up and the time until timeout and the size of the determination area (area 2) due to pen-down and the time to timeout have been described as being the same. It may be different. For example, the pen-down often follows the pen-up, and the pen-down often deviates from the pen-up position. Therefore, the size of the determination area (area 1, area 3) due to the pen-up or the time until the timeout is determined by the pen-down It may be larger than (Area 2).
(3) Dragging after moving the pointer FIG. 9 is a diagram for explaining the dragging case. In FIG. 9, as in FIG. 7, for easy understanding, the size of the determination region is expressed in one dimension, the vertical axis is the size of the determination region, and the horizontal axis is time. Further, in the figure, a white circle with D is indicated as pen-down by the input pen 20, and a white circle with U is indicated as pen-up by the input pen 20, and the solid line is the input pen 20. The movement is shown while being in contact with the input surface 13. In the figure, a hatched circle with D indicates that the left button of the mouse is down, and a hatched circle with U indicates that the left button of the mouse is up. Is shown. In addition, the hatched circle with the underlined U indicates that the pen-up and the left button up of the mouse overlap, and the hatched circle with the underlined D indicates the pen-down and the mouse It shows that the down of the left button overlaps.

First, the user moves the pointer displayed on the input surface 13 to an object such as an icon to be dragged. Thereafter, when the input pen 20 is pen-up (start event) from the object, the contact position of the input surface 20 of the last input pen 20 is stored as the pen-up position, and a determination area (area) of a predetermined size with the position as the center. 1) is generated. The determination area (area 1) decreases linearly until timeout.

When the input pen 20 is pen-down (next event), the pen-down position is detected, and it is determined whether this position is within the determination area (area 1). If it is within the determination area (area 1), it is determined that the object such as an icon has been lowered. Then, a determination area (area 2) having a predetermined size is generated around the pen-down position.

The user starts moving with the input pen 20 in contact with the input surface 13, and determines that the input pen 20 is dragged when the detection position of the input pen 20 is out of the determination area from the determination area (area 2). , Move the icon according to the movement of the pen. Then, when pen-up is performed, the stored pen-up position after the previous pointer movement or dragging is erased, the newly pen-up position is stored, and a determination area of a predetermined size ( Area 3) is generated.

In the above description, the size of the determination area (area 1 and area 3) due to pen-up and the time until timeout and the size of the determination area (area 2) due to pen-down and the time to timeout have been described as being the same. It may be different. For example, dragging and pen-up often continue after pen-down. In the case of drag, etc., it is possible to determine that the drag is faster by reducing the size of the determination area or shortening the time until timeout. The size of the determination area (area 2) or the time until timeout may be made smaller than the determination area (area 1, area 3) by pen-up.

Furthermore, during the drag, the input pen 20 may be temporarily separated from the input surface 13 due to shaking or the like (so-called drop). The following method can be considered as a countermeasure.

FIG. 10 is a diagram for explaining countermeasures against drops during dragging.

FIG. 10 differs from FIG. 9 in that the input pen 20 is moving (dragging), and the determination area size generated by the pen up of the input pen 20 after dragging and the time until timeout are stored. Is made smaller than the normal determination region.

FIG. 10 shows a case where the input pen 20 is dropped after the input pen 20 goes out of the determination area (area 2). The drop countermeasure area (determination area) is centered on the position where the input pen 20 is dropped (pen-up). Is generated. When the pen is downed in the drop countermeasure area (determination area), the drag is continued.

Similarly, the pen-up after dragging also generates a drop countermeasure area (determination area), and if the pen-down is not performed in the drop countermeasure area (determination area), the drag is ended.

As a result, even when the input pen is temporarily removed, the pen-down is performed again in the determination area, so that it is possible to realize a countermeasure against dropping, and it is possible to reduce the time required for determining the end of the drag, Can be done smoothly.
(4) Double-click after moving pointer FIG. 11 is a diagram for explaining double-click after moving the pointer. In FIG. 11, as in FIG. 7, for easy understanding, the size of the determination area is expressed in one dimension, the vertical axis is the size of the determination area, and the horizontal axis is time. In the figure, a white circle with D indicates a pen-down by the input pen 20, a white circle with U indicates a pen-up by the input pen 20, and a solid line indicates the input pen 20. A movement in a state where the input surface 13 is brought into contact is shown. In the figure, a hatched circle with D indicates that the left button of the mouse is down, and a hatched circle with U indicates that the left button of the mouse is up. Is shown.

First, when the user pens up the input pen 20 after moving the pointer or icon, the contact position of the input surface 20 of the last input pen 20 is stored as the pen-up position, and a predetermined size is determined with the position as the center. A region (area 1) is generated. The determination area (area 1) decreases linearly until timeout.

When the input pen 20 is pen-down, the pen-down position is detected, and it is determined whether this position is within the determination area (area 1). If it is within the determination area (area 1), it is determined that the object such as an icon has been lowered.

When the input pen 20 is pen-up within the determination area (area 2), it is determined that the pen is up with respect to an object such as an icon. In addition, the pen-up generates a determination area (area 3) having a predetermined size centered on the stored pen-up position (the first pen-up position after the pointer or icon is moved). The determination area (area 3) decreases linearly until timeout.

When the input pen 20 is pen-down, the pen-down position is detected, and it is determined whether this position is within the determination area (area 3). If it is within the determination area (area 3), it is determined that the object such as an icon has been lowered. Also, a pen-down generates a determination area (area 4) of a predetermined size with the pen-down position as the center. The determination area (area 4) decreases linearly until timeout.

Subsequently, when the input pen 20 is pen-up within the determination area (area 4), it is determined that the pen is up with respect to an object such as an icon. Also, a pen-up generates a determination area (area 5) of a predetermined size with the stored pen-up position (the first pen-up position after the pointer or icon is moved) as the center. The determination area (area 5) decreases linearly until timeout. If there is no event in the determination area (area 5) until the determination area (area 5) times out, it is determined to be a double click.
