Comparison of the TouchFree Switch to a Physical Switch; Children's Abilities and Preferences: A Pilot Study

This study compared a touch-free switch, which does not require physical access, with a physical touch-based switch, on several criteria such as speed, accuracy, and preference. Six children with physical disabilities, ages 7 to 15, completed computer activities with both switches. A mixed methodology of both quantitative and qualitative procedures was used. These included collecting data on the speed and accuracy of the participants when using each switch, and both student and caregiver/professional interviews. The findings suggested that both switches had advantages and disadvantages.
