Abstract
A computer input device consists of a long and slender, pencil like, cylinder which is horizontally and rotatably disposed on two supports at both its ends. A finger touching the cylinder applies a force on it which is countered by reactions at the supports. These reactions are sensed by force sensors and the ratio between them is used to calculate the position of the finger along the cylinder. This position is the “X” input of the device. The same finger can rotate the cylinder around itself in both directions. The angular position of the cylinder is measured by a rotary sensor and is then used as the second, “Y”, input.
