Abstract

An apparatus uses a guide toy vehicle and has a smart floor environment. The smart floor environment is filled with location tags. Data can be found in a back-end database for location tags of an exhibit unit through a wireless network. The data comprise multimedia information to improve learning. Thus, with the present invention students can have better learning for achieving a default teaching goal.

Claims
