Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a vector input device for instructing the moving direction and speed of a cursor (pointer) displayed on a monitor screen of a computer or the like.

[Conventional technology]

A mouse is an example of this type of vector input device. This mouse is a mechanical mouse, in which a small ball for the X-axis and a small ball for the Y-axis are brought into contact with a large ball that rotates at a 90 degree angle as it is moved on the desk, and the rotation of the two small balls is controlled. By detecting the direction and rotational speed with each sensor, and calculating the detection output of each sensor, the moving direction and moving speed of the large ball are obtained and displayed on the monitor screen accordingly. It is designed to move the cursor. In addition to mechanical mice, there are also optical mice.

[Problem to be solved by the invention]

However, this mouse has a relatively large shape in order to make it easy to hold in the hand, and since it needs to be moved and operated, a relatively large area on the console is required for this operation. There was a problem that it was considered.

SUMMARY OF THE INVENTION An object of the present invention is to provide a vector input device that allows a cursor to be instructed to move in a direction and speed by simply moving a finger (detected object).

[Means to solve the problem]

For this purpose, the vector input device of the present invention includes a touch panel that detects touches on XY coordinates, a display screen provided on the bottom surface of the touch panel, and a detection output of a touch of a detected object to the touch panel. and a control section that calculates the moving direction and speed of the touch panel, and is configured to display squares on the display screen and set the detection resolution of the touch panel according to the pitch of the squares.

〔Example〕

Embodiments of the vector input device of the present invention will be described below. FIG. 1 is a diagram showing a vector input device 1 according to one embodiment. This vector input device 1 has a keyboard 2 in which a plurality of ordinary keys 21 are arranged.
It consists of a square display screen 11 made of a group of LFL, D (light emitting diodes) or an LCD (liquid crystal display), and a touch panel 12 of an optical type or dielectric type provided to cover the top surface of the display screen 11. has been done.

FIG. 2 is a diagram showing the internal blocks of this vector input device l. The display screen 11 displays grids of a predetermined pitch under display control by the display control section 4 in accordance with display data output from the control section 3 consisting of a CPU. Further, in the touch panel 12, when the touch detection unit 5 detects a touch of a detected object such as a finger, the detection output is taken into the control unit 3, where it is processed at a resolution according to the grid and displayed on the monitor. It is output as a cursor position control signal on a display section (not shown). 6 is an RO that stores the processing program
This is a memory consisting of a RAM and the like that temporarily stores M and processing contents.

In this embodiment, the XY coordinates on the touch panel 12 are set according to the squares displayed on the display screen 11 as described above. Therefore, when a finger is placed on the top surface of the touch panel 12 and moved in an arbitrary direction, the position information of the finger is detected by the touch panel 12 over time and is imported from the touch detection section 5 to the control section 3. In step 3, the direction in which the finger moves and the speed of movement thereof can be calculated and obtained. Therefore, based on this calculation result, the cursor displayed on the monitor can be moved in a direction corresponding to the direction of movement of the finger at a speed corresponding to the speed of movement of the finger.

At this time, a fold switching function is given to a specific key of the keyboard device 2, and the display screen 1 of the vector input device 1
If the pitch (size) of the squares to be displayed on the vector input device 1 can be changed by operating this key, and the detection resolution of the touch panel 12 can be changed according to the pitch of the squares, the vector input device 1 can be Even if the finger is moved at the same speed, the cursor on the monitor screen moves slowly when the grid pitch is large, and moves quickly when the grid pitch is small. Therefore, when moving the cursor over a long distance, the grid pitch can be set small, and when moving the cursor finely, it can be set large, improving usability.

Note that if the entire keyboard device 2 is made into a touch panel type and a CRT is used for its display screen, the keyboard device 2 can be used as a normal keyboard device, and the entire surface can be used as a vector input device by switching the display screen. You can also do this.

〔Effect of the invention〕

As described above, the vector input device of the present invention inputs a vector by tracing the surface of the touch panel with an object to be detected such as a finger. Good and can be formed into small shapes. Furthermore, since grids indicating the resolution are displayed, the resolution can be changed by making the pitch of the grids switchable, which has the advantage of improving usability.
