Glitter

Abstract

This project introduces Glitter, an LLM-powered virtual assistant designed to assist practitioners in planning, executing, and refining ABA-integrated interventions. Through co-design iterations and a one-week field study with 11 practitioners, we evaluated Glitter’s usability, effectiveness, and potential for enhancing intervention delivery. The findings highlight Glitter as an adaptable tool while revealing key challenges and future directions. This work contributes insights into the design of virtual assistants for behavioral interventions and the integration of LLMs into practitioner support tools.
