HeadCross: Exploring Head-Based Crossing Selection on Head-Mounted Displays
summary
HeadCross implements a head-driven cursor on VR/AR headsets and selects by crossing into a target and crossing back; recognition uses sharp-turn detection and entrance–exit proximity on the boundary. Study 1 maps entry directions (four primary axes), finds larger targets slow movement and lengthen in-target paths, and dense layouts push users to start crosses farther away. Study 2 tests text entry and menu selection against dwell, hand gestures, and controllers: HeadCross matches dwell, beats hand gestures on speed/accuracy/fatigue, while controllers remain fastest in VR.
