Neck gesture recognition for head mounted display user : movable range of head turning

Abstract

This article proposes a motion recognition method for Oculus Rift, which is currently the most popular head mounted display available, by using neck motion as non-verbal interaction. We use sensor-fusion, which is already equipped on the Oculus Rift, to detect user's neck motion. The method can define three gestures, namely, "agree," "disagree," and "make a question," by determining the constancy of the head turning angle.
