Abstract
The apparatus for determining coordinates is used as a pointing device or a mouse device in a personal computer system. The present apparatus comprises plural speed sensors and an operating means such as a CPU. When the speed sensors are moved by an operator, each of the speed sensors detects each of accelerations thereof in predetermined axis directions. The detected accelerations of the speed sensors are converted into moving distances representative of the coordinates through a calculation of the operating means. By only holding and moving the present apparatus by an operator, it is possible to input the coordinates with ease and with accuracy because there is no need to provide a heavy metal ball of the conventional mechanical mouse device and a transparent board of the conventional optical mouse device.
