RE Methods for Virtual Reality Software Product Development: A Mapping Study

Software practitioners use various methods in Requirements Engineering (RE) to elicit, analyze, and specify the requirements of enterprise products. The methods impact the final product characteristics and influence product delivery. Ad-hoc usage of the methods by software practitioners can lead to inconsistency and ambiguity in the product. With the notable rise in enterprise products, games, and so forth across various domains, Virtual Reality (VR) has become an essential technology for the future. The methods adopted for RE for developing VR products requires a detailed study. This article presents a mapping study on RE methods prescribed and used for developing VR applications including requirements elicitation, requirements analysis, and requirements specification. Our study provides insights into the use of such methods in the VR community and suggests using specific RE methods in various fields of interest. We also discuss future directions in RE for VR products.
