Video communication systems work relatively well for family members and friends when they want to converse with each other between their homes. Yet it is much more challenging to share activities using mobile video conferencing in outdoor settings. We explored the design of mobile video conferencing systems that focused on allowing family and friends to participate in outdoor leisure activities together over distance. We created and studied two technology probe setups: shared geocaching and shared bicycling. Both used mobile cameras and streamed audio and video between remote family members or friends as they participated in the activities. Through these design and study explorations, we explore how family and friends make use of mobile video during leisure activities, what elements are important for the design of such systems, and how mobile video for outdoor leisure activities compares and contrasts to video calling in the home and, more generally, while mobile. Our research points to design considerations around camera views, when and how audio and video should be presented, and the privacy concerns of users and how to balance them with the benefit of the technology.

当家庭成员和朋友想要在他们的房屋之间相互交谈时，视频通信系统相对来说效果很好。然而，在室外环境中使用移动视频会议共享活动更具挑战性。我们探索了移动视频会议系统的设计，该系统的重点是允许家人和朋友一起远距离参加户外休闲活动。我们创建并研究了两种技术探针设置：共享的地理缓存和共享的自行车骑行。他们都使用移动摄像机，并在远程家庭成员或朋友参加活动时在他们之间流式传输了音频和视频。通过这些设计和研究探索，我们探索了家人和朋友在休闲活动中如何利用移动视频，哪些元素对于此类系统的设计至关重要，以及用于户外休闲活动的移动视频与在家中（更广泛地说，在移动时）进行视频通话的比较和对比。我们的研究指向围绕摄像机视图，何时以及如何显示音频和视频的设计注意事项，以及用户的隐私问题，以及如何利用技术的优势来平衡它们。
