MoHeat is a modular hardware and software platform designed for rapid prototyping of highly responsive, non-contact thermal feedback interactions. In our previous work, we developed an intensity-adjustable, highly responsive, non-contact thermal feedback system by integrating the vortex effect and thermal radiation. In this study, we further enhanced the system by developing an authoring tool that allows users to freely adjust the intensity of thermal stimuli, the duration of stimuli, the delay time before stimuli, and the interval between alternating hot and cold stimuli. This modular approach enables countless combinations of non-contact thermal feedback experiences.
