增强现实（AR）是一种新兴的技术，为计算机支持的协同工作（CSCW）提供了新的和引人注目的设计机会。为了促进基于AR的CSCW中的协作和通信，用户应该能够理解其他人如何与共享环境交互。支持这种意识的最有效方法之一是将用户交互与视觉提示（VC）联系起来，视觉提示提供关于其他用户动作的即时认知反馈（例如，指向、注释或操纵对象）。然而，在视觉语言方面，基于AR的CSCW在许多方面仍处于起步阶段，需要进一步的研究，特别是评估不同VC在提高协作、协同定位AR场景中用户感知的有效性。为此，本文提出了一个不同的风险投资的基础上，以前的文献评价。实验进行了不同的情况下，涵盖的主要目的，其中使用的风险投资，并在其中用户必须执行任务的复杂性不断增加。结果表明，志愿者积极评价提供的VC，因为他们有效地支持用户意识，并提供上下文和空间信息的所有参与者。
Augmented Reality (AR) is an emerging technology that offers new and compelling design opportunities for Computer Supported Cooperative Work (CSCW). To foster collaboration and communication in AR-based CSCW, users should be able to understand how others interact with the shared environment. One of the most effective ways to support this awareness is to link user interactions to visual cues (VCs) that provide immediate cognitive feedback about the actions of other users (e.g., pointing, annotating, or manipulating objects). However, AR-based CSCW is in many ways still in its infancy in terms of visual language, and further research is needed, especially to evaluate the effectiveness of different VCs in improving user awareness in collaborative, co-located AR scenarios. To this end, this paper presents an evaluation of different VCs based on previous literature. Experiments were conducted with different scenarios covering the main purposes for which VCs are used and in which users had to perform tasks with increasing complexity. Results show that volunteers positively evaluated the VCs offered, as they effectively supported user awareness and provided contextual and spatial information to all participants.
