Accessible gaming interface for children with cerebral palsy and related motor conditions
Switch Adaptor Kit is a modular hardware and software system that enables accessible gameplay using adaptive switches, robotic actuation, and mobile control.
The system translates simple user inputs into complex in game actions. It supports physical switches, Bluetooth inputs, and robotic manipulation of controllers or board game pieces.
Built in collaboration with The Pace Centre.
