Thermal imaging cameras, commonly used in application areas such as building inspection and night vision, have recently also been introduced as pedagogical tools for helping students visualize, interrogate and interpret notoriously challenging thermal concepts. In this paper we present a system for Spatial Augmented Reality that automatically projects thermal data onto objects. Instead of having a learner physically direct a hand-held camera toward an object of interest, and then view the display screen, a group of participants can gather around the display system and directly see and manipulate the thermal profile projected onto physical objects. The system combines a thermal camera that captures the thermal data, a depth camera that realigns the data with the objects, and a projector that projects the data back. We also apply a colour scale tailored for room temperature experiments.
