The concept of Interactive Video (IV) is examined in the light of the training requirements of the British Army. The reasons for the IV project are detailed, together with the basis for the selection of the system, project implementation, subject identification and the courseware design processes. Difficulties in project management and in interactive design are discussed and a structured approach to the design process presented. This approach was based on the combined use of structured design methods, flow charts, and screen layout documents. The results indicated that the approach was valid, that effective interactive design was difficult, and team stability vital. The knowledge gained from the study suggests that in view of the extent of initial and continuing resource overheads, the military use of IV is likely to focus on such applications as simulation where cost benefits may be more easily identified.
