In this study, the effectiveness of a “hands free” approach for operating video prompts to complete multi-step tasks was measured. Students advanced the video prompts by using a motion (hand wave) over a proximity sensor switch. Three young adult females with a diagnosis of moderate intellectual disability participated in the study. Effectiveness of the intervention was determined using a multiple probe design across three craft activities and replicated with the three young adults. Results indicate all three students demonstrated the ability to: master operation of the proximity sensor switch to operate the video prompts; independently complete the craft activities and; maintain their performance using the “hands free” approach.
