Physical Layer Accessibility

The dimension of VR accessibility concerned with whether users can physically access and operate VR hardware and interaction paradigms. This includes the setup process (putting on head-mounted displays, adjusting straps), manipulating controllers or using hand tracking, and engaging with locomotion methods. Physical layer barriers are well-documented in VR accessibility research and include issues like HMD weight causing head control problems, controllers requiring grip strength or bimanual operation, and free-roam locomotion requiring clear physical space. Physical layer accessibility is closely linked to individual users' physical bodies and ranges of motion, and is affected by temporal factors such as fatigue and daily form.
