Recovery Delay with Visual Feedback to Reduce Errors in Single-Switch Scanning Keyboards
Abstract
Purpose
Scanning switch keypads are commonly used as augmentative and alternative communication aids for people with complex communication needs. Low communication rates and high error rates are some of the problems that users of scanned keyboards encounter in daily use, which could lead to the abandonment of this type of technology. Thus, this study presents a new configuration system for scanned keyboards using visual feedback recovery time to help the user have a better performance and experience when using this type of alternative communication.
