ABSTRACT
Presentation aids, such as the laser pointer, are commonly used in lectures and public speeches. Their effect on the audience has not been properly studied. We present an experiment that compares several pointer alternatives. One of them is GazeLaser, a new solution that does not need a manually operated pointer, but is based on the lecturers' gaze. It fares well in comparison, but comes second to the pointing tool available in PowerPoint. The experiment brings up issues that need to be taken into account when developing GazeLaser further.

MAGIC pointing for eyewear computers
ISWC '15: Proceedings of the 2015 ACM International Symposium on Wearable ComputersIn this paper, we propose a combination of head and eye movements for touchlessly controlling the "mouse pointer" on eyewear devices, exploiting the speed of eye pointing and accuracy of head pointing. The method is a wearable computer-targeted ...
Gliding and saccadic gaze gesture recognition in real time
Eye movements can be consciously controlled by humans to the extent of performing sequences of predefined movement patterns, or 'gaze gestures'. Gaze gestures can be tracked noninvasively employing a video-based eye tracking system. Gaze gestures hold ...
Just blink your eyes: a head-free gaze tracking system
CHI EA '03: CHI '03 Extended Abstracts on Human Factors in Computing SystemsWe propose a head-free, easy-setup gaze tracking system designed for a gaze-based Human-Computer Interaction. Our system enables the user to interact with the computer soon after catching the user's eye blinks. The user can move his/her head freely ...
