Abstract
This paper presents a compact pointing device using an electrostatic capacitance fingerprint sensor that can also used as a fingerprint verification system. The sensor has a removable cover with 4 protruding portions made from conductive rubber. This cover is used during the pointing operation. Pressure distribution on the cover pressed by the operator is detected by processing of sensor images responding to the conductive rubber. Performance test was conducted to compare the performance of the proposed device with that of track point and touch pad. Promising result was obtained
