Cerebral Palsy

Users with cerebral palsy often experience contractures, limited hand mobility, or the inability to open their hands. They need a system that can accurately track limited movements, such as a wrist curve or controlled movement along a surface.

Fine Motor Control for Cerebral Palsy

The Challenge

Users with cerebral palsy often experience contractures, limited hand mobility, or the inability to open their hands. They need a system that can accurately track limited movements, such as a wrist curve or controlled movement along a surface.

AI Models & Capabilities

Wrist Curvature Tracking

Advanced AI tracks the subtle curvature of a closed or partially contracted wrist to perform mouse actions or controls.

Impact: Maximising Residual Movement - leverages the small, consistent motion available in the wrist/forearm.

Depth Force Fields as Switches

Creates two invisible 'force fields' in front of the hand, which are triggered by moving the hand forward/backward in a controlled way.

Impact: Multi-Action Switching - provides two distinct, hands-free 'click' or 'mode change' options.

Controlled Surface Drag

Recognises hand movement across a table as a cursor drag, for users with good horizontal control but poor vertical/in-air stability.

Impact: Stability and Reliability - works with the user's existing, reliable motor patterns.

Case Utility: Enabling Work & Productivity

Allows an adult with CP to use their reliable wrist curvature and depth movements to navigate apps, input data, play mouse-enabled games and operate office software.

Tracking the curvature of the wrists led to the development of in-air forcefields when users can control depth to make an action happen, even if they cannot open their hands.
