Voice loops, an auditory groupware technology, are essential coordination support tools for experienced practitioners in domains such as air traffic management, aircraft carrier operations and space shuttle mission control. They support synchronous communication on multiple channels among groups of people who are spatially distributed. In this paper, we suggest reasons for why the voice loop system is a successful medium for supporting coordination in space shuttle mission control based on over 130 hours of direct observation. Voice loops allow practitioners to listen in on relevant communications without disrupting their own activities or the activities of others. In addition, the voice loop system is structured around the mission control organization, and therefore directly supports the demands of the domain. By understanding how voice loops meet the particular demands of the mission control environment, insight can be gained for the design of groupware tools to support cooperative activity in other event-driven domains.

语音循环作为协调有助于航天飞机任务控制。

语音循环是一种听觉组件软件，是空中交通管理，航空母舰运营和航天飞机任务控制等领域中经验丰富的从业人员必不可少的协调支持工具。它们支持空间分布的人群之间在多个通道上的同步通信。在本文中，我们基于超过130个小时的直接观察，提出了语音循环系统为何是成功支持航天飞机飞行任务控制协调的媒介的原因。语音循环使从业者可以收听相关的通信，而不会打扰他们自己的活动或其他人的活动。此外，语音环路系统围绕任务控制组织构建，因此直接支持该领域的需求。
