Effects of Direct Systematic Instruction on Google Glass Orientation With Individuals With Intellectual Disability

Glass, designed by Google, is a fairly new wearable and mobile technology that projects an image into a glass prism above the eye and is currently in beta testing. A touch pad on the side of Glass allows users to engage with the device through swiping gestures and voice control to perform several functions similar to mobile devices. This initial study used a multiple probe across participants design to investigate the effects of direct systematic instruction (model-lead-test [MLT]) to teach three individuals with intellectual disability (ID) to operate Glass. To date, no study has been conducted using Glass with individuals with ID. Results demonstrated a functional relation between the direct systematic instruction and student performance with Glass orientation across all participants. Additionally, participants indicated positive experiences using this wearable/mobile technology based on social validity measures collected at the end of the study. Limitations, future research, and implications for practice are also discussed.
