Tapping-In-Place: Increasing the naturalness of immersive walking-in-place locomotion through novel gestural input

摘要: Walking-In-Place (WIP) techniques provide one possible solution to the problem emerging when an immersive virtual environment (IVE) offers a larger freedom of movement than physical where interaction is taking place. Such are particularly useful spatial constraints very prominent. However, many previous WIP rely on same gesture for input - stepping resembling performed walking up flight stairs. It seems that this may be perceived as more physically straining real which lead less natural experience. In paper we present two novel forms gestural locomotion and describe within subjects study comparing these traditional gesture. The gestures proposed are: wiping user alternately bends each knee, moving lower leg backwards, tapping in turn lifts heel without breaking contact with ground. Visual feedback was delivered through head-mounted display auditory provided by means 24-channel surround sound system. were evaluated terms naturalness, presence, world positional drift. significantly experienced strenuous other techniques. Finally, resulted
