Usability of the inductive tongue computer interface: Internet use, speaking, and drinking - evaluated by two users with disabilities.

Tongue computer interfaces have shown promising for both computer control and for control of assistive technologies and robotics. Still, evidence is lacking in relation to their usability resulting in speculations on their effectiveness for general computer use and their impact on other activities such as speaking, drinking, and eating. This paper presents the results of such a usability study performed with two individuals with tetraplegia. The results show a high acceptance of the Inductive Tongue Computer Interface with an average rating of 2.6 on a scale from 1 (normal) to 10 (unacceptable) and a low impact on speech after only 3 days of use.Clinical Relevance- This study emphasizes the applicability and adoptability of the Inductive Tongue Interface as a useful assistive technology for individuals with severe disabilities.
