Apparatus and method are disclosed for sensing a desired cursor position by detecting disturbance due to acceleration in each of three piezoelectric crystals located in a user movable housing. Crystals corresponding to X, Y, and Z dimensions are connected to means for converting disturbance due to acceleration into a voltage which is thereafter converted to appropriate signal format for implementation by a computer. The apparatus may be wired or wireless and in the form of a conventional mouse or a user wearable device.
