INTERACTIVE MULTI-SENSORY READING SYSTEM ELECTRONIC TEACHING/LEARNING DEVICE

摘要

An electronic learning/teaching device (100) operates with and without aprinted sheet element (20) having an arrangement of selectable content bymeans of a user responsive sensor array (142) beneath a surface (130)configured to receive the element. The sensor array is formed by cross-pointsof two sets of crossing conductive lines (246, 248), one set being drivensequentially with a radio frequency square wave and the other set beingsampled sequentially though a high impedance amplifier connection with anasynchronous detection circuit. Where more than one cross-point location isuser activated, algorithms (Fig. 12) are used to identify one cross-pointsensor location as the user activated selection.
