Abstract
A computer control device which provides spacial information to a computer or electronic game by sensing the linear acceleration or tilt angle of the control device. The computer control device includes an accelerometer having an enclosure containing a fluid and temperature sensing elements positioned within the enclosure. The fluid moves across the temperature sensing elements in free convection during acceleration or inclination of the enclosure causing a temperature differential between the temperature sensing elements which is measurable. The control device incorporating one or more of these accelerometers senses acceleration or tilt in one to three dimensions and may be used to control a cursor on a computer screen, a display of a virtual reality device, or other computer and electronic game displays.
