Handedness Effect and Its Implication for Designing Two-Handed Interactive Applications in Virtual Reality

摘要

This research studied how the handedness characteristic or the motor ability differences between the preferred hand and the non-preferred hand affected natural hand interaction result in VR. An experiment was conducted with 30 participants (8 left-handedness, 22 right-handedness) recruited. The participants were required to complete a series of target acquisition tasks in a specifically designed VR application. The experiment results showed that (1) the preferred hand had a higher efficiency in selecting targets than the non-preferred one; but (2) the non-preferred hand achieved a more satisfying accuracy than the preferred one; (3) the preferred hand resulted in a more persistent operation, but the non-preferred hand was pointed out to perceive fatigue more easily. Given above findings, implication and guidelines were discussed for developing more efficient and user-friendly interactive applications in VR.
