A Tangible Interface for Hands-on Learning

In this paper, we describe a tangible interface for hands-on learning using physical-tangible objects (pattern blocks). A computer recognizes the states of the user-handled objects in real time and it gives the users advice to execute learning tasks if necessary. In our approach, a pattern block is employed as a primitive piece. It helps the users to do direct manipulation in real environments, while displayed events in virtual environments help them to support the learning tasks. Concretely, we have developed the interaction system can support hands-on math activities
