Parkinson’s is a neurodegenerative condition that causes the breakdown of brain cells, leading to symptoms such as tremors. In many patients, these tremors get increasingly worse as their condition progresses, and ultimately prevents them from conducting daily tasks that include hand activity. In the past decades, Parkinon’s diagnosis has increased, although different regions have been impacted differently. The medical cost of Parkinon’s disease on those affected can be viewed on a national level. The significance of assistive devices, such as the intra-oral tongue-computer interface transcends traditional treatments by providing an alternate solution to improve the quality of life for Parkinson’s patients. This oral device, structured after a retainer, includes a mousepad located at the roof of the mouth, keyboard buttons behind the top and bottom front teeth and a metal bud attached to the tip of the tongue. The physical input of a tongue with an activation sensor touching certain keys on a sensor board increases accuracy of the necessary pointing and scrolling functions of any mobile device. The cost of this prototype is relatively cheaper than other devices. In the future, the researched device (IntraOral Tongue Computer Interface) can be utilized to help not only Parkison’s Disease patients, but also individuals with limited mobility. It helps these patients with performing day-to-day tasks, as well as with optimizing their current assistive devices.
