Velocity-Dependent Perception Threshold for Discrete Imperceptible Repositioning in a Virtual Environment During Eye Blinks

In this study, the relationship between a person’s walking speed and perception threshold for discrete implicit repositioning during eyeblinks in virtual environment is investigated. The aim to estimate thresholds forward backward translation following eyeblink occurrences. A psychophysical method called Staircase Transformed Weighted up/down utilized quantify repositioning. are estimated three different speeds: slow (0.58 m/s), moderate (0.86 fast (1.1 m/s). collected observations then analyzed using regression analysis. values imperceptible were 0.374, 0.635, 0.897 meters abovementioned speeds, respectively. Moreover, respective 0.287, 0.430, 0.572 same speeds. findings reveal proportional participant’s speed. As such, it possible imperceptibly reposition participant at greater distance when they faster relative situation slower. addition, results show that there more tolerance compared translation. These enable extension of manipulation types by Redirected Walking Technique. More specifically, allows implementing sophisticated composite redirected controller, which utilizes continuous gains simultaneously; helps not only with reducing cognitive load, but also amount physical space required support infinite free exploration an immersive environment.
