Unimanual Input

Interaction techniques designed to be operated with only one hand, enabling access for users who cannot use both hands due to disability, injury, or situational constraints. In VR contexts, unimanual input is important for users with upper limb impairments, amputations, or conditions like hemiparesis, as well as wheelchair users who may need one hand for wheelchair operation. Research has explored mapping bimanual VR interactions to single-handed control schemes, though fewer than 100 of the 300 most-used VR applications support one-handed operation, and this number is declining.
