ABSTRACT
The touchpad is the de facto standard input device for controlling the GUI on portable computers. Most touchpads detect only finger contact and ignores other physical actions, such as applying force or hovering over the device. In this paper, we introduce a novel touchpad capable of tracking finger hover and measuring normal and shear forces. We also present two design strategies for the hover- and force-enhanced touchpad: multi-level user interaction and mimicry of physical manipulation. We illustrate the two design strategies using two applications that we developed based on the design strategies.

A study on touch & hover based interaction for zooming
CHI EA '12: CHI '12 Extended Abstracts on Human Factors in Computing SystemsProximity is a useful medium for interaction with high interactive digital contents. It can be used in different contexts such as for navigation through depth in 3D space in zoomable interfaces. In this paper, we propose hover-based zoom interaction as ...
Force-enabled TouchPad in Cars: Improving Target Selection using Absolute Input
CHI EA '16: Proceedings of the 2016 CHI Conference Extended Abstracts on Human Factors in Computing SystemsCurrent automotive interfaces rely heavily on touchscreen interfaces which leverage simple and intuitive direct touch interaction. Since input and output are co-located, displays have to be positioned within hand's reach. When the display is outside the ...
Design and comparison of acceleration methods for touchpad
CHI EA '07: CHI '07 Extended Abstracts on Human Factors in Computing SystemsAs the resolution of a notebook display increases, the efficiency of a touchpad is becoming a more important issue. In particular, it is often observed that users scrape the pad repeatedly to reach the close button of a window. In this paper, we propose ...
