The collaboration in co-located shared environments has sparked an increased interest in immersive technologies, including Augmented Reality (AR). Since research in this field has primarily focused on individual user experiences in AR, the collaborative aspects within shared AR spaces remain less explored, and fewer studies can provide guidelines for designing this type of experience. This article investigates how the user experience in a collaborative shared AR space is affected by divergent perceptions of virtual objects and the effects of positional synchrony and avatars. For this purpose, we developed an AR app and used two distinct experimental conditions to study the influencing factors. Forty-eight participants, organized into 24 pairs, participated in the experiment and jointly interacted with shared virtual objects. Results indicate that divergent perceptions of virtual objects did not directly influence communication and collaboration dynamics. Conversely, positional synchrony emerged as a critical factor, significantly enhancing the quality of the collaborative experience. On the contrary, while not negligible, avatars played a relatively less pronounced role in influencing these dynamics. The findings can potentially offer valuable practical insights, guiding the development of future collaborative AR/VR environments.

研究虚拟元素错位对协作增强现实体验的影响

共置共享环境中的协作激发了人们对增强现实 (AR) 等沉浸式技术的兴趣。由于该领域的研究主要集中在 AR 中的个人用户体验，因此对共享 AR 空间内的协作方面的探索仍然较少，而且很少有研究可以为设计此类体验提供指导。本文研究了虚拟对象的不同感知以及位置同步和化身的影响如何影响协作共享 AR 空间中的用户体验。为此，我们开发了一款 AR 应用程序，并使用两种不同的实验条件来研究影响因素。 48 名参与者分成 24 对，参与了实验并与共享的虚拟对象共同互动。结果表明，对虚拟对象的不同感知并不直接影响沟通和协作动态。相反，位置同步成为一个关键因素，显着提高了协作体验的质量。相反，虽然不可忽视，但化身在影响这些动态方面发挥的作用相对不那么明显。这些发现可能会提供有价值的实用见解，指导未来协作 AR/VR 环境的开发。
