Tablet Tapping
A camera placed in the scene shows its view on a tracked hand-held tablet, and the user taps objects one by one on that image with a pen to add them to a multiple selection.
How it works
With a V8 HMD, an IS900 wand and a tracked Plexiglas tablet. The user travels to a viewpoint and a 3 s countdown places a camera there; its view is mapped onto the tablet. A pen crosshair shown on the image within 10 cm of the tablet aims, and the button casts a ray from the camera through that point, toggling the object hit. In a summative study (18 participants) on a wall of 100 cubes with 9, 36 or 64 targets, the parallel techniques were much faster than serial ones as the number of targets grew; whether the context was 3D or the tablet image made no difference.
