Researchers explored the effectiveness of a non-invasive inductive tongue-computer interface designed to assist individuals with motor disabilities in interacting with technology. The study involved five participants without motor disabilities and seven with disabilities, including five with spinal cord injuries and two with amyotrophic lateral sclerosis. Over several sessions, participants performed an intraoral target selection task to evaluate their ability to manipulate the integrated tracer.

Participants without motor disabilities improved their median target selection time by 26% and their median success rate by 15%. In contrast, those with spinal cord injuries showed a 40% improvement in success rate, although their selection times remained constant. One participant with amyotrophic lateral sclerosis increased his selection speed, while the other did not demonstrate significant improvement.

The study found that participants with motor disabilities were more likely to select incorrect targets compared to those without disabilities. Results indicate that repeated use of the tongue-operated device enhances target selection speed and accuracy, although individuals with motor disabilities may require longer dwell times to prevent unintentional target selection.
