Redirected touching: Difference between revisions

[[Redirected touching]] is a technique developed by Luv Kohli, a computer scientist, in which virtual space is warped to map several virtual objects to one real object that serves as a passive haptic prop. The real hand motion is therefore mapped differently in relation to the virtual hand motion, introducing discrepancies that compensate for the differences between the real and virtual objects. Like Redirected Walking, this technique also uses errors in human perception to introduce discrepancies between the virtual environment (VE) and the real one. This technique would not be of use if the differential mapping would be noticeable to the user <ref name=”1”> Kohli, L. (2013). Warping Virtual Space for Low-Cost Haptic Feedback.
