ChinMotion Rapidly Enables 3D Computer Interaction after Tetraplegia
This addresses the need for intuitive assistive devices to improve quality of life for people with tetraplegia, representing a novel application rather than an incremental improvement.
The paper tackles the problem of enabling hands-free computer interaction for individuals with severe paralysis by introducing ChinMotion, an interface that uses chin, lip, and tongue movements. After two hours of practice, it achieves superior point-and-click performance and accurate 3D control of a virtual robotic arm compared to existing interfaces.
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.
