Abstract
This paperless book is portable and uses removable ROM devices to provide the visual and aural information displayed in the paperless book. The book can be read in a visual mode, as print, or in an aural mode, as the spoken word corresponding to the print, or in both visual and aural modes. The display mode may be conveniently shifted back and forth between visual and aural, for use, for example, by a counter who uses the book in the aural mode while driving and switches to the visual mode while riding on a train. In addition, the visual display may be manipulated affecting the appearance, for use, for example, by persons with reduced visual acuity. Movies also may be viewed using the paperless book. Finally, portions of the text may be enhanced by additional visual images, music or other sounds.
