Handpad: a virtual mouse for controlling laptops in a smart home

Abstract

This study investigates the possibilities of equipping fixed furniture with touch screens to control laptops or other smart home devices, to create a holistic smart home control system. Although multi-touch screens have recently been integrated into desktop use, most users prefer a classical mouse for desktop input. This study introduces Handpad, which is a new indirect touch input device designed to control laptops in a smart home. Handpad combines the mobility of a touch screen with the precision of a mouse by tracking whole-hand movement on the touch screen and moving the screen pointer accordingly. In a user test, participants showed a high level of acceptance and positive attitudes toward Handpad.
