Design: 
Mechling et al evaluated PDA as a portable self-prompting device to increase independence across multiple step tasks, in this case, completing 3 recipes. They found that subjects were ablto to adjust prompt levels and maintain utilization in order to complete recipes over time

In this study, a personal digital assistant (PDA) with picture, auditory, and video prompts with voice over, was evaluated as a portable self-prompting device for students with autism spectrum disorder (ASD). Using a multiple probe design across three cooking recipes and replicated with three students with ASD, the system was tested for its effectiveness in increasing independent performance across the multiple step tasks. In addition, data were recorded for the number and types of prompts used by the students across time. Results indicate that the students with ASD were able to adjust the prompt levels used on the PDA and to maintain their ability to use the device to independently complete recipes over time.
