ABSTRACT:
BACKGROUND OF THE INVENTION
Field of Invention
The present invention is associated with electronic teaching aids; specifically an electronically augmented display board that is user-interactive.
Educational display boards in current use generally exist as non-interactive pictorials hanging on classroom walls. These display boards are thin inexpensive cardboard or plastic sheets imprinted with graphics and text depicting relational information, yet they provide no mechanism to foster the process of learning.
BRIEF SUMMARY OF THE INVENTION
An interactive electronic display board containing text and/or graphics wherein a hidden conductive matrix connects user input contacts located on the facing surface of the display board with a battery powered electronic module that generates audio response outputs based on the interpretation of answer input connections that are created by sensing a user's body resistance when contact is made across a pair of electrical sense contacts.
