SIDD is a compact and portable electronic data retrieval and display unit, based on a flat screen (e.g. CRT or LCD) display, a mass storage device and microcomputer technology. SIDD is a purpose built and ergonomically designed device suitable for displaying textual and graphical information stored on mass storage media (e.g. plug-in cartridges), as an alternative to printed matter counterparts. A key-pad allows selection of functions from a displayed menu. The display may be scrolled forwards or backwards, a line at a time or a page at a time. A Braille key-pad, synthesised voice output and colour display are also envisaged. <IMAGE> |
