Summary

This project will test the feasibility of developing a smart augmentative or alternative communication (AAC) system that is effective in delivering communication capabilities that automatically adapt to the users' physical abilities.

Detailed description

The diversity of the more than 1.3% of Americans who suffer from severe physical impairments (SPIs) preclude the use of common augmentative or alternative communication (AAC) solutions such as manual signs, gestures or interaction with a touchscreen for communication. This clinical trial will test the feasibility of developing a smart-AAC system designed using individually adaptive access methods and AAC interfaces to accommodate the unique manifestations of motor impairments specific to each user. The investigators will demonstrate the proof-of-concept that a single surface electromyographic (sEMG) and inertial measurement unit (IMU) hybrid sensor worn on the forehead can provide improvements in information transfer rate (ITR) and communication accuracy when integrated with an AAC interface that is optimized compared to a conventional (non-adaptable) interface for subjects with SPI.
