Abstract
An interactive apparatus is disclosed. The interactive apparatus has an audio recording mode and an audio playback mode. Further, the interactive apparatus includes a writing tool for manually writing on an encoded writing medium, an audio input device for recording audio, an audio output device for playing the recorded audio. Moreover, the interactive apparatus has an optical unit for determining position on the encoded writing medium of the writing tool and for recognizing information on the encoded writing medium, wherein recognition of a recording-enabling graphical element on the encoded writing medium activates the audio recording mode and enables time-synchronization of creation of writing on the encoded writing medium with the writing tool and recording of the audio, and further wherein recognition of a playback-enabling graphical element on the encoded writing medium activates the audio playback mode and enables multiple techniques to control playback of the recorded audio.
