Abstract: Apparatus for playing an interactive application using a DVD player (24) that generates images on a TV (22) responsive to addressed image data on a DVD (50), the apparatus comprising: a DVD (50) having application images encoded at addressed locations on the DVD; an interface unit (26) comprising an IR transmitter (34), at least one user input device and a processor; a readable memory device (RMD) (52), separate from the DVD (50), encoded with at least one algorithm for determining a DVD image address responsive to activation of the at least one input device by a user; wherein the processor determines an image address responsive to the at least one algorithm and activation of the at least one input device and controls the IR transmitter (34) to transmit an IR signal encoding the address to the DVD player.

Abstract: An electronic book comprising a plurality of leaves, each leaf comprising pages of printed material bound at one edge to form a spine, with electrical circuits formed in each leaf. A common electronic circuit such as a speech generator and/or controller cooperates with the electrical circuits on each of the various pages, connected to the electrical circuits in the leaves through conductive paths through the spine of the book. The electrical circuits in the leaves include electrical elements such as switches, and sensory output devices (e.g., thermochromic devices, light emitting diodes, thermo-olfactory devices, electrochromic devices, and the like). The electrical elements are associated with particular portions of the printed material so that the particular portions can be selectively highlighted or emphasized (e.g., designated by actuation of a visual or olfactory device and/or text read).
