What is it about?

A new approach to designing input device keys is proposed, and a TV remote controller is used as an example to demonstrate the new approach for studying the relationship between fingerprints and key geometry. One hundred subjects' fingerprints of thumbs and index fingers of both hands were collected, and a computer program was used for converting the fingerprint to a bitmap form.

Why is it important?

Subsequently, the data were analyzed to provide some guidelines for determining the key size and key shape for the input device. Finally, the fingerprints were used to study the pattern of finger press and the justification for keycap curvature for finger placement. * 本研究提出利用指紋之堆疊的方式,設計更合乎人因工程的鍵盤。


The results showed that the new approach can be useful in guiding designers of input device keys. A further benefit of this study is in providing a more systematic approach with considerable general potential for studying input device keys. * 本研究雖然目前的科技難以大量生產,但本研究之可貴在於大膽地提出創意的解決方法。
