INNER-SENSOR BASED POINTING DEVICE

摘要

An inner-sensor based pointing device (10) is presented. The pointing device includes a central housing (12) having an aperture and a sleeve (14) disposed surrounding a portion of the central housing. The sleeve is rotatable about the portion of the central housing and is slidable along a generally horizontal axis about the portion of the central housing. The pointing device further includes a sensor disposed in the central housing and aligned with the aperture, the sleeve positioned surrounding the sensor, wherein the sensor is capable of detecting rotational movement of the sleeve relative to the central housing and wherein the sensor is capable of detecting axial movement of the sleeve relative to the central housing. Additionally, the pointing device has a circuit in communication with the sensor, the circuit capable of transmitting data to a computer regarding the movement of the sleeve.
