| Abstract | We investigate mobile phone pointing in Spatial Augmented Reality (SAR). Three pointing methods are compared, raycasting, viewport, and tangible (i.e. direct contact), using a five-projector "full" SAR environment with targets distributed on varying surfaces. Participants were permitted free movement in the environment to create realistic variations in target occlusion and target incident angle. Our results show raycast is fastest for high and distant targets, tangible is fastest for targets in close proximity to the user, and viewport performance is in between. |
