摘要

本文介绍了一种采用静电电容式指纹传感器的小型指纹指向装置,该装置也可作为指纹验证系统使用。传感器有一个可拆卸的盖子,上面有4个由导电橡胶制成的突出部分。这个盖子在指向操作中使用。通过处理响应于导电橡胶的传感器图像来检测操作员压下的盖板上的压力分布。进行了性能测试,将该装置的性能与轨迹点和触控板的性能进行了比较。取得了令人满意的结果。

Development of a compact pointing device utilizing static-capacity fingerprint sensor
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
