Multimodal interface for alternative communication of people with motor disabilities
Abstract
Purpose
This work presents the development of an augmented and alternative communication system, consisting of a multimodal interface controlled by different types of signals (electromyography, electrooculography, accelerometer and ON/OFF button).
Methods
The multimodal interface was tested in volunteers with severe motor disabilities and without motor restrictions. The device was applied for controlling an alternative communication software based on automatic scanning and single ON/OFF commands.
Results
The volunteers used the system for more than 30 days and demonstrate a significant evolution in the control of the multimodal system developed.
Conclusion
The multimodal interface developed presented stability and reliability using only an adaptive channel to receive both EMG signals as EOG. Also, the possibility of adding external sensors ON/OFF type extends the amount of people who could be assisted with the use of the system, which makes it more useful and versatile.
