Cinegrams for self-directed learning

Abstract

A cinegram is a new type of interactive computer-based document that makes explicit use of time-based media such as animation in presenting complex technical information. A cinegram prototype, showing the oil system of one of the latest Rolls Royce turbine engines, is under development. Cinegrams are based on a network of composite nodes which can be customized in order to reflect varying requirements. Also, cinegrams provide different ways of accessing technical information: they can be browsed or searched: nodes can be linked together to presentation sequences; and finally, direct interaction with valves, gauges, etc. will trigger simulations of state changes within the system. We expect that cinegrams will be useful as flexible reference tools, pointing to system-related documents and data. Another potential application is the use of cinegrams for self-directed learning. Contrary to more restricted training environments, self-directed learning emphasizes the users' particular interests. An investigation of the mapping relations between cinegram and physical engine and a description of the basic three dimensions of cinegram structure (system, component and state) lead to the suggestion of a simple browsing mechanism based on proximity. Furthermore, we discuss the possibility of encoding node adjacency constraints which would define a dynamic browsing space for state transition networks, and the role of temporal granularity in the definition of cinegram sequences. Currently, the cinegram prototype is evaluated both with “novice” users (students of Technical Communication at Coventry University) and experienced users of the Customer Services department at Rolls Royce.
