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