H4VR: One-handed Gesture-based Text Entry in Virtual Reality Using a Four-key Keyboard
Saba Fallah, I. Scott MacKenzie
Abstract
H4VR is a text entry method offering two layouts – flat and cross – of a four-key keyboard in VR. Hand gestures select the keys with a different selection method for each layout. The entry speed and error rate were measured and analyzed in a five-session longitudinal user study. Five participants entered ten phrases on each keyboard in each session. They reached an average entry speed of 4.57 and 3.63 words per minute on the flat and cross keyboards, respectively. The average error rate was less than 2% on both keyboards.
