Abstract

Accurate X,Y position determining digitizers presently require a precision array of wires embedded in the tablet. In rear-projection tablets these wires tend to limit the optical quality of images projected on the screen. Principles of acoustic radar are applied in a device which achieves better resolution, at a lower cost and without the use of wires, either in a tablet or a cursor. The function of acoustic reflectors for automatic calibration is described, achieving an accuracy of + mn; 0.01% of the distance to the sensors. In the case of small tablets, a hand-held stylus may be tracked at the rate of 900 locations a second.

UIST '16: Proceedings of the 29th Annual Symposium on User Interface Software and Technology

We explore how gaze can support touch interaction on tablets. When holding the device, the free thumb is normally limited in reach, but can provide an opportunity for indirect touch input. Here we propose gaze and touch input, where touches redirect to ...
Exploring and Understanding Unintended Touch during Direct Pen Interaction

The user experience on tablets that support both touch and styli is less than ideal, due in large part to the problem of unintended touch or palm rejection. Devices are often unable to distinguish between intended touch (i.e., interaction on the screen ...
