Abstract

PURPOSE:To easily position a cursor by means of a mouse by forming a line for detecting the vertical movement of a mouse to such a curve that follows the natural movement of human's hands. CONSTITUTION:A line 1 for detecting the vertical movement of a mouse and another line 2 for detecting the lateral movement of the mouse are provided on a mouse pad 3. The line 1 is a circular arc of r1 in radius and a group of lines for detecting the vertical movement is constituted by parallel-displacing the center of the line 1 in the front-rear direction of the mouth pad 3 at fixed pitches d1 while the radius r1 is fixed. The radius r1 is set to 27-33cm in accordance with the average length between elbows and palm of human's arms. Accordingly, the number of times of crossing the line 1 of a vertical movement detecting section in a mouse detecting section is reduced when the mouse is moved in the lateral direction by turning human's arms around elbows. Therefore, a cursor can be positioned easily on a screen, since the cursor can be moved in the lateral direction with less movement in the vertical direction.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a mouse pad for an optical mouse, and more particularly to a mouse pad provided with a pattern that is optically detected by a detection section provided in the mouse.

[Conventional technology]

Conventional mouse pads for optical mice are disclosed, for example, in Patent Application Publication No. 58-500777 and Patent Application Publication No. 58
When a person who was equipped with an optically observable orthogonal grid pattern as described in No. 98242 moved an optical mouse by hand on a mouse pad, the detection part of the optical mouse The orthogonal grid pattern on the mouse pad is detected, and the amount of horizontal movement of the optical mouse is detected using the vertical pattern of the orthogonal grid pattern that the optical mouse crosses. The horizontal pattern of the grid pattern was used to detect the amount of downward movement of the optical mouse.

[Problem to be solved by the invention]

With the intention of a human moving the cursor on the display screen horizontally,
When moving a mouse on a desk, the user unconsciously moves the mouse by rotating the mouse around the elbow. Therefore,
In order to move the cursor horizontally as intended using the conventional mouse pad with the above-mentioned orthogonal grid pattern, a human must use the rotational movement in conjunction with bending and stretching the wrist or moving the elbow itself to move the mouse body directly to the side. This increases mouse user fatigue.

[Means to solve the problem]

The mouse pad for an optical mouse of the present invention is characterized in that the line group for detecting the amount of mouse movement in the vertical direction is a plurality of curved curves with a concave bottom line arranged at equal intervals. shall be.

〔Example〕

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a plan view of one embodiment of the present invention, showing a mouse pad 3.
A line 2 for detecting horizontal movement is provided on the top as a line 1 for detecting vertical movement of the mouse (as shown). The vertical movement detection line 1 is a circular arc with a radius r, and the vertical movement detection line 1 is formed by fixing the radius r and moving the center in parallel in the front and back direction of the mouse pad 3 at a constant pitch d. A group is formed. The radius r1 is set between 27 cm and 33 cm according to the average length from the elbow to the center of the palm (Ergonomics Handbook 2nd Edition, P, 360 Kanehara Publishing), and the pitch d1 is set according to the vertical movement detection of a conventional mouse pad. Equivalent to line pitch. The horizontal movement detection line 2 consists of a group of parallel straight lines equally spaced, similar to a conventional mouse pad.

In such a mouse pad, when the mouse is moved left and right by rotation around the elbow, the number of times that the vertical movement sensing part of the mouse detection part crosses the vertical movement detection line 1 is increased. mouse pad, so the cursor on the screen moves horizontally without moving up or down as much.

FIGS. 2(a) and 2(b) are a plan view of another embodiment of the present invention and an explanatory diagram for explaining the vertical movement detection line 1, respectively. The mouse pad 13 is provided with a line 11 for detecting vertical movement of the mouse (as shown) and a line 2 for detecting movement in the action direction. Vertical movement detection line 11
Foil X2/(r2+I2) 2) +(y2/r22
)=1, the major axis and minor axis of the ellipse are fixed, and the focal point is moved in parallel in the front-rear direction of the mouse pad at a constant pitch d2, thereby forming a group of lines for detecting vertical movement. r2 in the above formula representing an ellipse is 27 cm
and 33cm, and L2 is a length proportional to the amount of left-right movement of the elbow, which can be seen from the movement of the mouse, and is 5C! 11 to 15c
m, and the pitch d2 is equivalent to the line pitch for detecting vertical movement on a conventional mouse pad. The horizontal movement detection lines 12 consist of a group of parallel straight lines equally spaced, similar to the conventional mouse pad.

In the embodiment shown in FIG. 2, when the mouse is rotated around the elbow and simultaneously shifted in the left-right direction, the cursor on both sides moves horizontally without moving up or down much.

〔Effect of the invention〕

As explained above, according to the present invention, the vertical movement detection line is curved to follow the natural movement of the human hand.
The mouse makes it easy to position the cursor. Also,
Since the movement of the mouse becomes simpler, it has the effect of reducing user fatigue.
