摘要:
An electronic learning device configured to receive in a predetermined orientation a book (2). The book includes a first (16a, 44) and second (16b, 46) page. The device further includes a base (122), cover (114) and book mounting assembly (118). A controller is in electrical communication with a position sensor (232) for detection the presence of a selector.
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.
