Investigation to Angular Resolution in Cube-Orientation-Based Interactions
Ji Bin Yin, Tao Liu · Advanced materials research · 2012
This study empirically explores a cube-shaped tool, focusing on the properties of its angle input. By tracking the fiducial marker on each side of the cube in real-time, basic operations such as rotating and tilting can produce the angle input modalities. We conduct an experiment that investigates the use of the angle input to perform a set of experimental tasks. In the experiment we design an angle selection task, varying the angle position and interval. The experimental results show that for rotation angle even 1 degree of angle can still be accurately discriminated whereas that limit goes beyond 3 degrees in case of tilt. A logarithm model can describe the relationship between angle interval and selection time.
