Interactive videodisc: Designing for learning

IVD can be considered a subset of the emerging multimedia teclmologies. It is worth observing. as Fletcher (1990) does; "At present there is no hardware technology that can competitively provide the functionalities that interactive videodisc systems can, but digital video, digital audio, and compact disc technology are all developing rapidly and will soon claim at least some of the territory now held by interactive videodisc systems." Ultimately, one of the digital derivatives of CD-ROM, or possibly a permutation of Digital Video Interactive, will emerge as the next fonnat to be widely adopted by training providers. Regardless of the format which does eventually gain ascendancy there is still a great deal to be learnt from the experience of designing and implementing IVD.
