The study found that using the gesture mode was faster than the menu selection mode for the majority of actions.

Researchers in the U.K. designed HotGestures, a system that allows the use of quick hand gestures to select tools to create objects and designs in virtual environments.

“The system continuously receives observations of the user’s finger and hand movements for both hands through the headset’s integrated hand tracker,” explains Per Ola Kristensson at the University of Cambridge, adding that artificial intelligence evaluates the hand movements and predicts which tool for which the user is signaling.

Participants piloting the new system indicated they found using the gesture mode was faster than a menu selection mode for the majority of actions, and that there was no significant difference in error rate between the two modes.
