Abstract
An interactive drawing tablet is provided having a housing and at least one surface on which printed media is mounted. A delivery device is electrically coupled to the interactive drawing tablet and is configured to hold a writing implement. An array of emitters are embedded in the surface and configured to emit signals. The delivery device is configured to receive the signals from the emitters when the delivery device is brought into proximity to the individual emitters and thereby determine a location on the printed media. The interactive drawing tablet is equipped with a speaker for emitting audio media to the user of the tablet. The interactive drawing tablet provides a user with instructions as to actions that should be taken with respect to the printed media.
