A three-dimensional spatial input apparatus including a series of coplanar, single axis accelerometers configured to provide information on translation along and rotation around a set of orthogonal axes. A preprocessing computer determines the acceleration values output by the accelerometers and converts these values into a series of acceleration, velocity and position values in relation to the axis system, with corrections based on a change in the influence of gravity on the device as it rotates. The values are transmitted to an object control computer which takes appropriate action, including moving a cursor, rotating a displayed object, and controlling remote devices. The spatial input apparatus can have an attached pointer and be used as a three-dimensional digitizer in conjunction with the object control computer.
