Using a Personal Digital Assistant to increase completion of novel tasks and independent transitioning by students with autism spectrum disorder.

Three students with autism used a Palm Pilot to guide them through new classroom tasks. The PDA showed picture, sound, and short video prompts that faded out on their own.

The team compared the PDA against regular picture strips taped to the desk. They measured if kids finished each step and moved to the next task without help.

Two of the three students finished more steps when the PDA coached them. All three switched from one task box to the next faster with the PDA than with picture strips.

Inside one task, the PDA and picture strips worked the same. The big win was moving between tasks.

Bigby et al. (2009) ran the same PDA two years earlier, but prompts never faded. Adding auto-fade is the upgrade you see here.

Szempruch et al. (1993) first used photo schedules. The PDA simply digitizes that old idea and makes prompts disappear on their own.

Spriggs et al. (2015) looks like a clash: they praise tablet videos while this paper praises PDA prompts. The gap is fake. One study used self-model videos; the other used step-by-step prompts. Different tools, same goal.

Chang et al. (2011) swapped the PDA for a Kinect camera. Both gadgets pushed users through tasks, showing the idea works across hardware.

If you still hand kids picture strips, try a cheap tablet with auto-fading prompts instead. You load the task once, the device slowly removes help, and students switch tasks without you hovering. Start with one learner and one multi-step job; measure completion and between-task latency for a week. You should see the same jump the authors found.
