Bimanual Interaction

Interaction techniques in computing and VR that require the coordinated use of both hands simultaneously, such as holding two controllers, performing gestures with both hands, or operating dual joysticks. Bimanual interaction presents significant accessibility barriers for users with upper limb impairments, amputations, hemiparesis, or conditions affecting one side of the body. In VR, many applications default to bimanual input, requiring users to hold and operate two controllers simultaneously. Accessible alternatives include unimanual (one-handed) input options, voice commands, head tracking, and eye-gaze control.
