[DC] Understanding and Leveraging Head Movement as Input for Interaction

Head movement is an intuitive and fundamental input modality for interactions. This PhD investigates head movement as an input modality for improving interaction efficiency and user experience. It encompasses three core components: 1) a systematic literature review analysing existing head interaction techniques, 2) the development and evaluation of head interaction techniques for head-mounted displays (HMDs), and 3) the generalisation of design principles derived from HMD-based research to other interfaces. The design of interaction techniques integrates fundamental knowledge of head movement kinematics, the natural coordination of the head with the eyes and hands, and control-display mappings. This research contributes to understanding head movement as an input modality and novel interaction techniques that harness its potential to enhance user interfaces across a range of devices.
