JPH0279116A - Mouse pad for optical mouse - Google Patents

Abstract

PURPOSE:To easily position a cursor in the vertical direction with a mouse by forming a line group for detecting the moving quantity of the mouse in the lateral direction of a group of straight lines radially arranged from a center below the line group. CONSTITUTION:A line 2 for detecting the vertical movement of a mouse and lines 1 for detecting lateral movement of the mouse are provided on a mouse pad 3. The line 1 is a radius vector and the distance (r) between the center of the vector and that of the mouse pad is set within a range of 27-50cm by adding the horizontal length from shoulder to elbows of human's bodies to the average length of human's arms from elbow to palm centers. Accordingly, the number of times of crossing the line 1 of a lateral movement detecting section in the detecting section of the mouse is reduced when the mouse is moved in the front-rear direction by the bending movement of elbows. Therefore, a cursor can be positioned easily on a screen, since the cursor vertically moves with less movement in the lateral direction.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an optical mouse pad, 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. 59 Sho.
It had an optically detectable pattern in the form of an orthogonal grid as described in US Pat. When a human moves the optical mouse on the mouse pad by hand, the detection part of the optical mouse detects the orthogonal grid pattern on the mouse pad, and the optical mouse detects the orthogonal grid pattern on the mouse pad. The horizontal pattern of the optical mouse was used to detect the amount of movement of the optical mouse in the horizontal direction, and the horizontal pattern of the orthogonal grid pattern that the optical mouse traversed was used to detect the amount of vertical movement of the optical mouse.

[Problem to be solved by the invention]

With the intention of a human moving the cursor up and down on the display screen,
When moving a mouse on a desk, the user subconsciously moves the mouse by bending and stretching the elbow.

According to this bending and stretching movement, the mouse moves radially around the shoulder. Therefore, there is no problem when the mouse is directly in front of the shoulder of the hand holding the mouse, but if it is shifted left or right from the shoulder, the mouse may be placed against the user's intention.
The cursor moves radially across the screen. In order to move the cursor up and down as intended using the conventional mouse pad with the above-mentioned orthogonal grid pattern, it is necessary to restrain the left and right direction by combining the bending and stretching movement with an elbow lifting movement. This put strain on the upper arm muscles and wrist joints, increasing fatigue for mouse users.

[Means to solve the problem]

The mouse pad of the present invention is characterized in that the line group for detecting the amount of mouse movement in the left-right direction is composed of a group of straight lines arranged radially centered at the bottom.

〔Example〕

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a plan view of an embodiment of the present invention, in which a mouse pad 3 is provided with a line 1 for detecting vertical movement and a line 2 for detecting horizontal movement of a mouse (not shown). The horizontal movement detection line 1 is a radius vector, and the distance r between the center of the radius radius and the center of the mouse pad is the average length from the elbow to the center of the palm. Ergonomics Handbook Expanded 2nd Edition, P, 360. Add the horizontal length from shoulder to elbow to 27cm to 50cm.
Take between cm. Also, the radial pitch θ (rad) is d
If this is the line pitch for detecting horizontal movement of a conventional mouse pad, it is taken as d/r.

The vertical movement detection line 2 consists of a group of parallel straight lines spaced at equal intervals, similar to the conventional mouse pad.

According to such a mouse pad, when moving the mouse back and forth by bending and stretching the elbow, the number of times that the left-right movement sensing section of the mouse crosses the left-right movement detection line 1 when using a conventional mouse pad. Therefore, the cursor on the screen moves vertically without shifting much to the left or right.

〔Effect of the invention〕

As explained above, in the present invention, the horizontal movement detection line is made radial to follow the natural movement of the human hand.
It becomes easier to position the cursor in the vertical direction using the mouse. In addition, since the mouse movement operation becomes simple, the user's fatigue is reduced, which is effective.

[Brief explanation of the drawing]

FIG. 1 is a plan view of one embodiment of the present invention. In the figure, 1 is a line for detecting horizontal movement, 2 is a line for detecting vertical movement, and 3 is a mouse hat.
