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.

软件从业者使用需求工程（RE）中的各种方法来引出、分析和指定企业产品的需求。这些方法会影响最终产品的特性并影响产品的交付。软件从业人员临时使用这些方法可能会导致产品的不一致和模糊性。随着企业产品、游戏等跨领域的显着增长，虚拟现实（VR）已成为未来的一项重要技术。 RE开发VR产品所采用的方法需要详细研究。本文介绍了用于开发 VR 应用程序的 RE 方法的映射研究，包括需求获取、需求分析和需求规范。我们的研究提供了对此类方法在 VR 社区中的使用的见解，并建议在各个感兴趣的领域使用特定的 RE 方法。我们还讨论了 VR 产品的 RE 未来方向。
