Abstract
Traditionally, part-task simulation development has involved large amounts of time and effort. This was due to: 1) the inherent complexity of designing real-time software; 2) difficulty of converting dea/concept into specific software engineering requirements/specifications; 3) the need for extensive interconnected computer systems (both graphical and non-graphical). There are 3 activities involved in the creation of a part-task simulation: 1) the physical display format; 2) the definition of the input (Simulation Logic); 3) the definition of the response to the inputs (Display Logic). The Interactive Display Design Tool (IDDT) was a concerted effort to allow parts of the external interface to be created directly by interface designers, rather than software engineers. The original version of IDDT allowed the designer to interactively create and modify display formats. The current capability of IDDT allows interface designers to partially create and modify display and simulation logic. This paper discusses the specific methodology used within IDDT: display lists and look-up tables, and cites examples and capabilities of the tool. In conclusion, specific instances of significant savings in time and effort required for part-task simulation creation are given.
