VReqST: A Requirement Specification Tool for Virtual Reality Software Products

Developing Virtual Reality (VR) software products with discrete and incremental requirements is a challenging task for VR practitioners. A domain expert's assistance plays a key role in VR product completeness, as most VR requirements are abstract or under-specified during the early stages. Slight changes to the requirements can significantly impact the overall flow of the VR software development process. In this paper, we introduce VReqST, a tool for VR requirement analysts to specify requirements for building effective VR software products. It is developed based on a Role-based model template for specifying virtual environments, custom behaviors, VR-specific algorithms, user-flows, action responses, timeline of events, etc. The tool has been developed after several interactions with VR practitioners from industry & academia. We share our insights on the effectiveness of this tool in practice.
