ChinMotion Rapidly Enables 3D Computer Interaction after Tetraplegia

TL;DR

ChinMotion is a noninvasive interface that allows individuals with tetraplegia to quickly and intuitively control 3D devices, outperforming existing methods after minimal training.

Contribution

The paper introduces ChinMotion, a novel noninvasive interface that harnesses preserved chin, lip, and tongue functions for rapid 3D control in tetraplegic individuals.

Findings

Superior point-and-click performance after two hours of practice

Enables accurate 3D control of virtual robotic arms

Outperforms existing interfaces in speed and accuracy

Abstract

Individuals with severe paralysis require hands-free interfaces to control assistive devices that can improve their quality of life. We present ChinMotion, an interface that noninvasively harnesses preserved chin, lip and tongue sensorimotor function after tetraplegia to convey intuitive control commands. After two hours of practice, ChinMotion enables superior point-and-click performance over existing interfaces and it facilitates accurate 3D control of a virtual robotic arm.
