We introduce new metrics to help explain 3D pointing device movement characteristics. We present a study to assess these by comparing two cursor control modes using a Sony PS Move. “Laser ” mode used ray casting, while “position ” mode mapped absolute device movement to cursor position. Mouse pointing was also included, and all techniques were also analyzed with existing 2D accuracy measures. Results suggest that position mode shows promise due to its accurate and smooth pointer movements. Our 3D movement metrics do not correlate well with performance, but may be beneficial in understanding how devices are used.
