In this seminar, we will present an empirical comparison of eleven barehand, mid-air mode-switching techniques suitable for virtual reality in two experiments.
The first evaluates seven techniques spanning dominant and non-dominant hand actions. Techniques represent common classes of actions selected by a methodical examination of 56 examples of the prior art. The standard “subtraction method” protocol is adapted for 3D interfaces, with two baseline selection methods, a barehand pinch and device controller button.
A second experiment with four techniques explores more subtle dominant-hand techniques and the effect of using a dominant hand device for selection. We will also discuss the results that provide guidance to practitioners when choosing barehand, mid-air mode-switching techniques, and for researchers when designing new mode-switching methods in VR.
