Augmented reality (AR), virtual reality (VR) and mixed reality (MR) are technologies of great potential due to the engaging and enriching experiences they are capable of providing. Their use is rapidly increasing in diverse fields such as medicine, manufacturing or entertainment. However, the possibilities that AR, VR and MR offer in the area of environmental applications are not yet widely explored. In this paper we present the outcome of a survey meant to discover and classify existing AR/VR/MR applications that can benefit the environment or increase awareness on environmental issues. We performed an exhaustive search over several online publication access platforms and past proceedings of major conferences in the fields of AR/VR/MR. Identified relevant papers were filtered based on novelty, technical soundness, impact and topic relevance, and classified into different categories. Referring to the selected papers, we discuss how the applications of each category are contributing to environmental protection, preservation and sensitization purposes. We further analyse these approaches as well as possible future directions in the scope of existing and upcoming AR/VR/MR enabling technologies.

增强现实、混合现实和虚拟现实在自然和环境中的应用调查

增强现实 (AR)、虚拟现实 (VR) 和混合现实 (MR) 是具有巨大潜力的技术，因为它们能够提供引人入胜和丰富的体验。它们在医学、制造或娱乐等不同领域的使用正在迅速增加。然而，AR、VR 和 MR 在环境应用领域提供的可能性尚未得到广泛探索。在本文中，我们展示了一项旨在发现和分类现有 AR/VR/MR 应用程序的调查结果，这些应用程序可以有益于环境或提高对环境问题的认识。我们对 AR/VR/MR 领域的几个在线出版物访问平台和过去的主要会议进行了详尽的搜索。根据新颖性、技术合理性、影响力和主题相关性过滤确定的相关论文，并分为不同的类别。参考选定的论文，我们讨论了每个类别的应用如何为环境保护、保存和敏化目的做出贡献。我们进一步分析了这些方法以及在现有和即将推出的 AR/VR/MR 支持技术范围内可能的未来方向。
