Abstract: Efficient sharing and intelligent support of experimental resources are important reform directions for laboratory opening. To improve the openness efficiency of our college’s sensory integration laboratory and solve the problems of insufficient and unsystematic supporting resources in a targeted manner, this study innovatively proposes an integrated tool for open experiment support based on AI Agent technology from the perspective of learner subjectivity, providing students with timely and urgently needed intelligent assistance in all key links. Developed on the HiAgent intelligent agent platform, this assistant constructs a dialogue-flow intelligent agent and realizes core functions including equipment and safety information inquiry, generation and evaluation of sensory integration training programs, process data assessment, and virtual role simulation training. The results show that students have a high acceptance of the intelligent agent assistant, and its functions can effectively meet students’ actual needs for supporting resources in open experiments. The design of this assistant provides an effective reference for the digital and intelligent transformation of open and shared experimental resources.
