Cost-Effective Virtual Reality Simulation for Chemistry Practicum using Hand Gesture

Abstract

We developed a virtual reality (VR) simulation of a chemistry practicum that incorporates the act of pouring liquid using hand gestures. This addresses the need for safe, cost-effective alternatives in chemistry education while still exercising practicum motor skills. Our simulation centers on the practicum of making picric acid, which presents significant both cost and safety challenges. Utilizing Leap Motion hand gesture technology as an input method offers a more affordable option than traditional VR controllers. We conducted usability testing with 16 participants, including a lecturer and undergraduate students from multiple backgrounds, to evaluate the application’s effectiveness and gather feedback. Results indicate that the simulation works as intended and accurately represents the practicum, achieving marginal usability. The application can reduce costs by at least IDR 658,638.00 per session and eliminates hazards associated with handling picric acid, highlighting its potential as a valuable educational tool.
