2. Description of the Related Art Conventionally, in an information processing apparatus using an electrostatic induction or electromagnetic induction type tablet, the position of the pen tip is detected even if the pen tip is about 5 to 10 mm away from the input surface of the tablet. Is possible. This function is called proximity sensitivity.

[0003]

In the above-mentioned conventional information processing apparatus, only the information that the pen has entered the proximity sensitive range and the information that the pen has exited the proximity sensitive range have been used.

[0004] The present invention has been made in view of such circumstances, and has as its object to provide an information processing apparatus capable of inputting more information from a tablet and an input processing method thereof.

[0005]

According to the first aspect of the present invention, an information processing apparatus contacts an input member with an input surface of a proximity sensitive input unit.

[0007]

FIG. 1 shows the configuration of an embodiment of an information processing apparatus according to the present invention. The tablet 2 is an electrostatic induction or electromagnetic induction type proximity sensitive tablet. The tablet control unit 4 controls the tablet 2, and determines the position of the pen 2, that is, the input coordinates when the input pen 6 is in contact with the input surface of the tablet 2 and when the input pen 6 is in the proximity sensitive range where the input pen is not touched. Transfer to processing unit 8. The processing unit 8 causes the data, the format, and the like to be displayed on the flat display 12 including, for example, a liquid crystal display device via the display control unit 10. Tablet 2 and flat display 12
Are integrated, and input coordinates and display positions are given a certain correspondence.

[0008] The processing section 8 has a proximity instruction detecting means 8S. The proximity instruction detecting means 8S is configured by a processor and a program of the processing unit 8, and determines that the input is a predetermined input when the movement of the pen 6 in the proximity sensitive range that does not touch the input surface of the tablet 2 satisfies a predetermined condition. Figure 2 shows tablet 2
3 shows the proximity sensitive range NH in the height direction with respect to the input surface 2A of the tablet 2. In this specification, moving the pen 6 within the proximity-sensitive range that does not touch the input surface of the tablet 2 to give an instruction to the information processing apparatus is referred to as “proximity instruction”. FIG. 4 shows an example of the approach instruction. In this example,
A scroll instruction is defined as moving the pen 6 linearly and continuously twice in the same direction at a speed equal to or greater than a predetermined value at a speed equal to or higher than a predetermined value within a proximity sensitive range where the input surface of the tablet 2 is not touched. .

During normal writing, the pen 6 is
And moves into the proximity-sensitive area for the next input (hereinafter referred to as "moving during writing"), so that it is necessary to distinguish this moving during writing from the proximity instruction. . The following factors can be considered as factors to be considered for distinguishing the two. 1. Movement at a distance equal to or greater than a predetermined value (this is unlikely to occur during normal writing) 2. Movement at a speed equal to or greater than a predetermined value (this is also unlikely to occur during normal writing) 3. Within a predetermined time The combination of the multiple movement shapes that occurred during the writing match (this is also unlikely to occur during normal writing movement)
In 4 , the combination of two similar straight lines)

FIGS. 5 and 6 show the proximity instruction detecting means 8S.
The operation of FIG. First, the proximity instruction detecting means 8S, that is, the processor of the processing unit 8, determines in step S1 of FIG.
When the proximity instruction stroke is detected, the processing in FIG. 6 is performed to determine whether this is a valid proximity instruction stroke. FIG.
In the process (1), the proximity instruction detecting means 8S first sets the variables T and I to 0 (step S15), detects the pen position at that time, and stores it in the register P [I] (step S16). Next, the proximity instruction detecting means 8S
After waiting for a certain period of time, T = T + 1 (step S17),
At that time, it is checked whether or not the pen 6 is in the proximity response range (step S18). If yes, the proximity instruction detecting means 8S sets I = I + 1 (step S19), detects the pen position at that time, and stores it in the register P [I] (step S20). Then, the proximity instruction detecting means 8S repeatedly performs the processing of steps S17 to S20.

In step S18, when it is detected that the pen 6 has moved out of the proximity sensitive range, the proximity instruction detecting means 8
S checks whether the distance from the pen position stored in the register P [0] to the pen position stored in the register P [I], that is, the pen movement distance is equal to or more than a predetermined value (step S2).
1). If it is equal to or more than the predetermined value, the proximity instruction detecting means 8S next checks whether the time T required for moving the pen is equal to or less than the predetermined value (step S22). If the distance is equal to or smaller than the predetermined value, the proximity instruction detecting unit 8S determines that the instruction is valid (step S2).
3). It should be noted that the proximity instruction detecting means 8S determines in step S21
In step S22, if it is detected that the moving distance of the pen is not longer than the predetermined value, or if it is detected in step S22 that the time T required for moving the pen is not shorter than the predetermined value, it is determined that the proximity instruction is invalid (step S24).

When the proximity instruction detecting means 8S performs the processing of FIG. 6 in step S2 of FIG. 5 and determines that it is a valid proximity instruction, it measures a time Tint until the pen 6 enters the next proximity sensitive range ( Steps S3, S4 and S5).
If the time Tint is equal to or longer than the predetermined value, the proximity instruction detecting means 8S determines that the previous, that is, the first stroke has performed the proximity instruction alone, determines the shape of the first stroke, and responds to the shape. Execute processing (step S9)
And S10). As the proximity instruction by one stroke, for example, a circle, a triangle, and a rectangle can be processed as meaning copy, deletion, and conversion, respectively.

Before the time Tint becomes equal to or longer than the predetermined value, the pen 6 enters the proximity sensing range (steps S5 and S6),
Upon detecting the second stroke of the proximity instruction (step S
7), the proximity instruction detecting means 8S performs the processing of FIG. 6 in step S8. If it is determined that the instruction is a valid approach instruction, the approach instruction detecting means 8S determines the shapes of the first and second strokes (steps S11 and S12) and determines the association between the first and second strokes (step S11). S13), and causes the processing unit 8 to execute a process corresponding to the determination result (step S14). For example, the proximity instruction detecting means 8S continuously and linearly moves a distance equal to or more than a predetermined value twice in the same direction at a speed equal to or higher than a predetermined value within a proximity responsive range where the pen 6 does not touch the input surface of the tablet 2. When it is determined that the processing has been performed (the proximity instruction in FIG. 4), the processing unit 8 causes the processing unit 8 to execute processing corresponding to this, that is, scroll processing.

Note that the proximity instruction indicating scrolling need not always be performed with two linear strokes. For example, a "s" written large and fast may be defined as scrolling.

Further, in the above embodiment, the approach instruction detecting means 8S is constituted by a combination of a processor and a program, but may be constituted by dedicated hardware.

Further, in the above embodiment, the proximity instruction detecting means 8S is provided in the processing section 8, but it may be provided in the tablet control section 4.
