ISRE: immersive scenario-based requirements engineering with virtual prototypes
Virtual prototyping is a useful approach for refining requirements for complex designs. However, the use of virtual reality (VR) technology can cause usability problems that can be interpreted as false positive requirements errors. The immersive scenario-based requirements engineering (ISRE) method guides the analysis of problems encountered during the testing of virtual prototypes and helps assign causes to either genuine requirements defects or to usability issues with VR technology. The method consists of techniques for walkthrough testing, testing with users, causal analysis of observed problems and the design of scenario-based analysis sessions. The method is described and its use illustrated with a case study of validating requirements for an aircraft maintenance application.
