A new depth perception model was developed to investigate the effect of deep jump on the human visual system in virtual reality images. In addition, the effect of parallax change on depth perception based on HTC Vive head-mounted display was evaluated, and the variation of the perception with jump parallax was analysed. The experimental results showed that the reaction time was proportional to the absolute value of parallax change. Furthermore, the parallax transition response time of the approaching angle of view was longer, the target depth and depth variations were negatively correlated with the physiological comfort, and the variation in the depth was positively correlated with the emotional influence. The model was applied to the creation and evaluation of actual images, and a pixel-by-pixel reaction time distribution map based on horizontal parallax was obtained.
Key words： virtual reality; parallax change; depth perception; reaction time; visual comfort
