Résultat majeur : TORUSDESKTOP: POINTING VIA THE BACKDOOR IS SOMETIMES SHORTER
TORUSDESKTOP: POINTING VIA THE BACKDOOR IS SOMETIMES SHORTER
07 mai 2011

S. Huot, O. Chapuis, P. Dragicevic. ACM CHI 2011.
When pointing to a target on a computer desktop, we may think we are taking the shortest possible path. But new shortcuts become possible if we allow the mouse cursor to jump from one edge of the screen to the opposite one, i.e., if we turn the desktop into a torus. We discuss the design of TORUSDESKTOP, a pointing technique that allows to wrap the cursor around screen edges to open this pointing back- door. A dead zone and an off-screen cursor feedback make the technique more usable and more compatible with every- day desktop usage. We report on three controlled experi- ments conducted to refine the design of the technique and evaluate its performance. The results suggest clear benefits of using the backdoor when target distance is more than 80% the screen size in our experimental conditions.
