Tongue-computer interface

Background

In the UK, approximately 2500 people become paralysed annually due to spinal cord injury and about 50% of those exhibit tetraplegia. Also, approximately 25% of people with a disability in the UK have limited, or no, digital capability.

Intended outcomes

This project involves the development of a wearable, form-fitted, tongue-computer interface to allow the tongue to control a computer pointing device, giving computer access to individuals unserved by traditional routes. The tongue-computer interface is intended to improve independence for the user, assisting with care outside the hospital and facilitating remote interaction between professionals and patients.

Tongue-based sensors can provide a high number of control inputs and require low physical effort, compared to other types. The project will include: lab testing and refinement of two types of sensor arrays; refinement of relevant sensor electronics; prototype development for a computer pointing device; and, development of fully-encapsulated sensor and electronics, with a wireless computer link.
