Objectives and Approach

The partners in this project have noted the growing demand for programmable large-screen video displays for use in a wide variety of applications including training, retailing, teleconferencing, notice boards, point-of-sale terminals and map displays. The performance requirements for such devices may be summarised as:

The main aim of the LIT project is to produce a demonstrator which meets these needs.

Back-projection of liquid crystal displays is the chosen display technology. Development work on this aspect of the system will centre on producing high-resolution LCDs and an ultra-compact, distortion-free projection system which is expected to be lighter and less bulky than the conventional projection CRT systems.

The technology required to realise the interactive screen has been defined after human factors studies in the early phases of the programme.

The architecture of the system will be designed in such a manner that a remote link could be incorporated at a later stage.

Two working units will be produced: one will be a prototype feasibility demonstrator as close as possible to a final product, aimed at the training and retailing market; the other will be used for assessment purposes.

An important feature of the project is the use of human-computer interaction methodology throughout, to optimise user-friendliness and versatility and with the aim of minimising future iterations in the product design.

The range of potential applications for these types of terminals can be expected to be widened with the use of remote communication links (not planned in this phase) such as radio, ISDN, mains-borne, infrared and telephone. A significant market is expected to develop in the next 10 years for remotely programmable terminals. The UK training market is expected to be 1000 units per year, with a total European training, rental and retail application market many times greater.
