An Evaluation of AccessBraille: A Tablet-Based Braille Keyboard for Individuals with Visual Impairments

Braille is a different symbolic alphabet that is used by people with visual impairments to communicate. Since the use of smartphones has become an essential part of peoples' lives, we should benefit from this connection and use smartphones as a training tool. AccessBraille is an iPad application that helps users practice Braille in different interactive ways. The goal of AccessBraille is to provide training for novice Braille individuals who want to practice Braille. A usability test was conducted to evaluate the usability of the app, validate the app's capability of facilitating the practicing of Braille characters and discover ways to enhance the app design and use. Data was collected and later analyzed to assess the difficulty involved with task completion.
