Abstract

Collaborative virtual environments (CVE) are usually evaluated according to the following aspects: cohesion between team members, implicit communication, and task performance. The degree of user awareness is another important aspect that deserves attention, especially when the CVE is 3D and immersive. 3DCVEs have the main goal of attaining a high degree of teamwork by exposing the team members to a suitable level of immersion that normally involves the stimulus of more than one sense, normally vision, hearing and touch. In this work, we present and discuss a new approach to measure the collaboration degree in immersive 3DCVEs. User awareness is measured by monitoring the use of the interaction and visualization schemes provided by the VE from different points of view, such as self awareness in a collaborative team, awareness of the other, and awareness of the work group. We conducted a case study where two users simultaneously immersed in the same VE were invited to walk together, assuming different roles. One user was invited to guide his colleague and, afterwards, the roles were swapped to guarantee equal participation, individual responsibility and positive interdependence, which are all mandatory features in a collaborative task.
沉浸式三维协同虚拟环境中协作度的度量
协作虚拟环境通常从团队成员之间的凝聚力、隐式沟通和任务绩效三个方面进行评价。用户意识程度是另一个值得关注的重要方面,特别是当CVE是3D和沉浸式的时候。3dcve的主要目标是通过将团队成员暴露在适当程度的沉浸感中来实现高度的团队合作,这种沉浸感通常涉及不止一种感官的刺激,通常是视觉、听觉和触觉。在这项工作中,我们提出并讨论了一种新的方法来衡量沉浸式3dcve中的协作程度。用户意识是通过从不同的角度监控VE提供的交互和可视化方案的使用情况来衡量的,例如协作团队中的自我意识、对他人的意识和对工作组的意识。我们做了一个案例研究,邀请两个用户同时沉浸在同一个VE中,扮演不同的角色。一个用户被邀请去指导他的同事,之后,角色互换,以保证平等参与、个人责任和积极的相互依存,这些都是协作任务的强制性特征。
