Abstract

PURPOSE:To eliminate the need for an operation until the operation started at the time of starting movement is stopped even in the case of a continued movement instruction by converting the integrated value of a moving variable in operation into a two-dimensional unit distance moving signal to be outputted to a computer. CONSTITUTION:This two-dimensional vector information input device is provided with a pair of moving variable detecting means 1 for independently detecting moving variables in two directions intersecting orthogonally with each other in each fine unit time, an integrating means 2 for converting the meanings of the detected moving variables in each fine unit time as two-dimensional acceleration vector information and integrating the converted vector information by time to obtain two-dimensional speed vector information, a speed attenuation instruction detecting means 3 for detecting a moving speed attenuating instruction and attenuating the two-dimensional speed vector information outputted from the means 2, and a unit distance moving signal sending means 4 for sending a two-dimensional unit distance moving signal in accordance with the two-dimensional speed vector information outputted from the means 2. In this case, operation is a moving speed acceleration/deceleration instruction, and when the operation is aborted, the movement of a fixed speed is restored. Consequently, the sending of a two-dimensional unit distance moving signal to the computer body 5 is continued until the operation is stopped by the moving speed acceleration/deceleration instruction or operation in the direction reversed to the moving direction.

The two-dimensional vector information input device of this embodiment uses two orthogonal vector information input devices.
A pair of movement amount detection means 1 that independently detect the movement amount in the direction and output a two-dimensional counter increase/decrease signal according to the movement amount, and a two-dimensional counter increase/decrease signal output from the pair of movement amount detection means 1. 2 as an integral means to independently count
Detects a dimensional integer counter 2 and a movement speed attenuation instruction 2
Speed attenuation instruction detection means 3 that attenuates the two-dimensional count value of the two-dimensional integer counter 2; and unit distance movement that sends out a two-dimensional unit distance movement signal (movement pulse) in accordance with the two-dimensional count value of the two-dimensional integer counter 2. It is comprised of a frequency variable pulse generator 4 as a signal sending means. Note that the reference numeral 5 indicates a computer main body into which a two-dimensional unit distance movement signal is input.

FIG. 2 is a perspective view showing the external appearance of the mouse 6 as an example of the two-dimensional vector information input device of this embodiment. The mouse 6 is provided with a brake button 7 on the side, particularly for giving an instruction to the speed attenuation instruction detection means 3.

Next, the operation of the two-dimensional vector information input device of this embodiment configured as described above will be explained.

A pair of movement amount detection means 1 each send out a two-dimensional counter increase/decrease signal for each unit distance movement in two orthogonal directions.

The two-dimensional integer counter 2 increases or decreases a two-dimensional count value in accordance with a two-dimensional counter increase/decrease signal for each unit distance movement sent from the movement amount detection means 1.

The speed attenuation instruction detection means 3 has no effect when no instruction to attenuate the moving speed is detected, but for example, while the brake button 7 is pressed down with the mouse 6 and an instruction to attenuate the moving speed is detected, the speed attenuation instruction detecting means 3 detects a two-dimensional integer. 2 for counter 2
It continues to send out a counter absolute value decrease signal that decreases the absolute value of the dimension count value.

The two-dimensional integer counter 2 decreases the absolute value of the two-dimensional count value in accordance with the counter absolute value decrease signal sent from the speed attenuation instruction detection means 3.

The two-dimensional integer counter 2 receives 2 as a result of increase/decrease by the movement amount detection means 1 and the speed attenuation instruction detection means 3.
The dimension count value is sent out as a two-dimensional frequency signal.

The variable frequency pulse generator 4 includes a two-dimensional integer counter 2
It receives the two-dimensional frequency signal sent from the computer, converts it into a two-dimensional unit distance movement signal, and sends it to the computer main body 5.

The computer main body 5 receives the two-dimensional unit distance movement signal sent from the variable frequency pulse generator 4 in the same sense as the two-dimensional unit distance movement signal output from the conventional two-dimensional vector information input device. It turns out.

As described above, in the two-dimensional vector information input device of this embodiment, the operation is an instruction to accelerate/decelerate the moving speed, and when the operation is stopped, the movement is at a constant speed.

The transmission of the dimensional unit distance movement signal continues.

FIG. 3 is a graph showing the action of the two-dimensional vector information input device of this embodiment limited to one direction. The moving position recognized by the computer main body 5 corresponds to the integral of the moving distance starting from the operation start position. It is also shown that the instruction to attenuate the movement speed causes the computer main body 5 to stop moving and become a new base point.

〔Effect of the invention〕

As explained above, the present invention converts a value obtained by integrating the amount of movement during an operation into a two-dimensional unit distance movement signal to the computer. This has the effect that no operation is required until it is stopped.

In particular, the provision of the speed attenuation instruction detection means eliminates the need for complicated operations for stopping, and the unit distance movement signal sending means sends a two-dimensional unit distance movement signal to the computer main body, similar to the conventional one. This has the advantage of not placing any burden on the computer or software.
