ABCD SW: autistic behavior & computer-based didactic software

Abstract

In this demo we show an open source software (SW) program designed to facilitate the execution of Applied Behavior Analysis (ABA) intervention with low-functioning autistic children. The SW is based on Augmentative and Alternative Communication (AAC) and Discrete Trial Training (DTT). The SW automatically records data extractable from the session (times, success/error, etc.), while the tutor inserts subjective data such as type and level of prompt provided to a child, along with comments. The SW adapts the trial to the child's abilities (receptive/verbal) to make it accessible (comprehensible and operable). To offer the child a simple and accessible interaction environment, the tutor and child user interfaces are kept separate and offered on mobile devices. Using a laptop, the tutor sets the exercise that appears on the child's tablet. Synchronization between devices offers the tutor a real-time summary of actions performed by child, freeing up his/her cognitive resources needed to memorize this information and possibly favoring the decision-making process for the ABA intervention.
