Towards an Understanding of the Effects of Amplified Head Rotations
Régis Kopper, Cheryl Stinson, Doug A. Bowman · 2011
Amplified head rotations have been proposed as a method to overcome the limitations of narrow field of view (FOV) and field of regard (FOR) in virtual reality (VR) systems, but little is known about the effects of amplification on task performance with various VR displays. We performed an exploratory study using visual scanning and counting tasks to investigate the effects of amplification with varying FOV and the detectability of amplification by users. In the visual scanning task, FOV had a significant effect on performance, with a non-significant trend for an interaction between amplification and FOV. Amplification had a significant effect on performance in the counting task. We discuss the implications of these findings for designers of VR systems and propose further studies to clarify our understanding of the effects of amplified head rotations.
