The Optimal Interactive Space for Hand Controller Interaction in Virtual Reality

The definition of the optimal interactive space for hand direct operation, is an universally beneficial but less explored issue in the virtual reality (VR) domain. Through a specifically designed target acquisition experiment, it was found that (1) a bent arm posture generated a higher operational speed and accuracy, as well as lower physical exertion than a stretched arm posture; (2) arm operation at the shoulder below position was less laborious but more efficient and accurate than that at the shoulder above position; (3) the individual characteristic of handedness influenced the controller interaction performance at left- and right- sided interactive spaces.
