HAND-HELD PLAYBACK DEVICE, SYSTEM AND METHOD

摘要

A hand-held playback device primarily useful for audio teaching of correct pronunciation of words for transducing mini-records from the pages of books and other sheet material upon which is shown or otherwise displayed some of the same information as is recorded on the record. To effect playback, the device is necessarily aligned in a manner whereby the human observable material is designated, for example, to the eye of the student, while at the same time it is being played back to him. Braille characters can be observed by the student at the same time as they are broadcast on a loudspeaker to the student so as to reinforce the learning process in one embodiment.
