Layout of Direct Input Interface Based on Virtual Space

Abstract

Immersive virtual environment has the potential to realize natural interaction in users' close interactive space. To explore the efficient layout of direct input interface suitable for hand-eye cooperation in virtual environment, through the freehand clicking experiment, the participants were required to quickly click the random targets in three different spatial depths. The results show that in the visual field of head mounted display (HMD), the depth has a significant impact on the arm movement time and clicking accuracy. It is suggested that the low-frequency and short-term interactive content can be placed in the left and upper right areas of the visual field, and the high-frequency and long-term content can be placed in the central and lower area with low consumption endurance. The down-right area is not suitable for quick click. This paper proposes an efficient direct input interactive layout in virtual space based on spatial dimensions and arm kinematics.
