Key Points

To identify key behavioral features using machine learning to predict when individuals with developmental disabilities require instructor intervention during virtual reality coffee extraction training.
Extracted feature variables by calculating relative distances between 10 virtual barista tools and the user's left and right hand controllers during multi-step coffee extraction tasks.
Identified the top five predictive variables using a random forest algorithm, followed by binary logistic regression to evaluate their statistical significance in predicting the need for instructional intervention.
Random forest modeling prioritized five controller-to-tool relative distance variables as the strongest contributors to predicting learner intervention status.
Binary logistic regression confirmed that specific spatial distance variables significantly distinguished learners who required instructional support from those who did not.

Implication

Machine learning analysis identifies key motion predictors for instructor intervention in students with developmental disabilities, indicating automated assistance can support virtual reality...
