Users readily embrace the rapid advancements in virtual reality (VR) technology within various everyday contexts, such as gaming, social interactions, shopping, and commerce. In order to facilitate transactions and payments, VR systems require access to sensitive user data and assets, which consequently necessitates user authentication. However, there exists a limited understanding regarding how users' unique experiences in VR contribute to their perception of security. In our study, we adopt a research approach known as ``technology probe'' to investigate this question. Specifically, we have designed probes that explore the authentication process in VR, aiming to elicit responses from participants from multiple perspectives. These probes were seamlessly integrated into the routine payment system of a VR game, thereby establishing an organic study environment. Through qualitative analysis, we uncover the interplay between participants' interaction experiences and their security perception. Remarkably, despite encountering unique challenges in usability during VR interactions, our participants found the intuitive virtualized authentication process beneficial and thoroughly enjoyed the immersive nature of VR. Furthermore, we observe how these interaction experiences influence participants' ability to transfer their pre-existing understanding of authentication into VR, resulting in a discrepancy in perceived security. Moreover, we identify users' conflicting expectations, encompassing their desire for an enjoyable VR experience alongside the assurance of secure VR authentication. Building upon our findings, we propose recommendations aimed at addressing these expectations and alleviating potential conflicts.

翻译：用户在日常场景中快速接受了虚拟现实（VR）技术的快速发展，例如游戏、社交互动、购物和商业活动。为支持交易与支付，VR系统需访问用户的敏感数据和资产，这自然要求进行用户身份验证。然而，目前关于用户的独特VR体验如何影响其对安全性的认知仍了解有限。本研究采用“技术探针”研究方法来探究这一问题。具体而言，我们设计了探索VR身份验证过程的探针，旨在从多维度引发参与者的反馈。这些探针无缝集成至VR游戏的常规支付系统中，从而构建了自然的实验环境。通过定性分析，我们揭示了参与者交互体验与安全感知之间的相互作用。值得注意的是，尽管VR交互中遇到可用性挑战，参与者仍认为直观的虚拟化身份验证流程具有优势，并充分享受VR的沉浸式特性。此外，我们观察到这些交互体验如何影响用户将既有身份验证认知迁移至VR环境的能力，进而导致安全感知差异。同时，我们识别出用户对愉悦VR体验与安全VR身份验证保证之间的矛盾期望。基于研究发现，我们提出旨在应对这些期望并缓解潜在冲突的改进建议。
