Guided play: digital sensing and coaching for stereotypical play behavior in children with autism
summary
A prototype system uses an iPad building-blocks app with background outlines, turn-taking prompts and graded rewards to sense play, model constructions as graphs and run graph-based similarity & hierarchical clustering to categorize behaviors. A multiple-baseline study with 6 children aged four–five compares free-play versus guided-play phases and finds guided digital coaching increases symbolic construction categories and reduces repetitive play; transfer back to real blocks is not demonstrated because children refuse the physical toys.
