Interactive Spatial AR for Classroom Teaching

The authors fuse the virtual objects in science and the action of teachers on real podium by developing an interactive spatial AR system, in which teachers could interact with virtual objects by their gesture in real-time presentation, and the images of virtual objects that projected on a transparent projection screen were aligned and matched to calibrate with their body part's position. The students will see virtual objects are seamlessly matched on the real teachers on podium space as if they are real things that are just under the control of the teachers. The students will immerse into the presentation more deeply, hence enhance the cognitive effect of classroom teaching and learning.
