RESUMO
Camera Mouse is a freely available software program that visually tracks the movement of facial features to allow individuals with motor impairments to control a computer mouse. The goal of this case study was to provide an evaluation of Camera Mouse as a computer access method as part of a multiple modality communication system for an individual with cerebral palsy. The participant was asked to reproduce sentences and respond to ethical dilemmas for language sampling. Tasks were completed using natural speech and an AAC solution consisting of Camera Mouse paired with an orthographic selection interface and speech synthesis. The participant completed a questionnaire for satisfaction with the introduced assistive technology. Camera Mouse resulted in higher intelligibility than natural speech, while natural speech had a higher rate. She used more complex language with her natural speech. The participant rated Camera Mouse as at least 3/5 on all measures, including 5/5 on weight and safety. The results of this case study suggest Camera Mouse is a promising computer access system for communication supported by the participant's satisfaction rating, expressive language, and synthesized speech production capabilities.
