A technique is described whereby optical mouse pads, as used with personal computers, have different grid patterns so as to enable the mouse user to perform both gross and fine cursor positioning on different grid patterns without software intervention. The concept is designed to be used with commercially available puck and mouse systems. (Image Omitted) The concept utilizes peel-off materials, such as paper or vinyl, as shown in Fig. 1, on which is embedded a grid pattern. With such a pad, a mouse user can count how many steps it has taken during positioning operations. The grids can be of different varieties, such as log-log and polar griding. Also, fine grids can be located in the middle and gradually become farther apart at the edges of the pad.
