Wheelchair Seating

The configuration and customization of a wheelchair's seating components to provide appropriate support, comfort, and functional positioning for the user. Proper wheelchair seating considers trunk support, head positioning, pelvic alignment, and pressure distribution. For users of gaze-based communication technology, wheelchair seating must position the head stably at the correct angle relative to the device's camera. Research in Ghana found that lack of wheelchairs with adequate seating was a primary barrier to gaze-based AAC use, even when users had the cognitive and motor skills to operate the technology.
