Abstract

Identifying appropriate roles for the components of advanced interfaces is a significant research challenge. We expect head movements to assume their natural role in controlling viewpoint, and we are investigating the use of head tracking to provide perspective control. We apply this to a task of adjusting the viewpoint to detect a target at the bottom of a virtual cylinder. The cylinder varies in diameter, height and orientation. We record viewpoint trajectories and elapsed times. Observers participate in one of two conditions: in the Head-as-Head condition, viewpoint changes correspond to observing a real scene; in the Head-as-Hand condition, rotational directions are reversed, simulating manipulation of an object. To evaluate initial learning and consolidation effects there are two sessions of massed trials, two day apart. The results show a rapid learning effect, and solid retention over the two day interval. Performance levels are similar for the two opposite mappings, indicating flexibility in the use of head- controlled viewpoint. We continue to apply the paradigm to other questions about head-controlled viewpoint manipulation, such as establishing a boundary between small movements producing natural parallax changes, versus extended movements involving large scale viewpoint changes.
