A pointing device for controlling the direction and speed of cursor movement, wherein a capacitive sensor comprises two pairs of electrodes symmetrically arranged on orthogonal axes (X'OX, Y'OY) and consisting of a set of branches extending between those adjacent electrodes. The shape of the branches is determined according to two simple relationships to ensure a good correlation between the position of a finger placed on the sensor and the speed of the cursor in all directions. The simple design, strong construction and good ergonomic properties of the device make it suitable for common computer-related applications. |
