A remote pointing technique using pull-out

Abstract

Reaching objects displayed on the opposite side of a large multi-touch tabletop with hands is difficult. This forces users to move around the tabletop. We present a remote pointing technique we call HandyPointing. This technique uses pull-out, a bimanual multi-touch gesture. The gesture allows users to both translate the cursor position and change control-display (C-D) ratio dynamically. We conducted one experiment to measure the quantitative performance of our technique, and another to study how users selectively use the technique and touch input (i.e., tap and drag). © 2013 Springer-Verlag.
