SpaceTag是一个虚拟对象，只能从有限的位置和时间段访问。SpaceTag系统的用户可以使用带有位置传感器的便携式终端查看和创建SpaceTag。我们将其归类为叠加虚拟系统，其中虚拟对象基于时间和空间坐标叠加到真实的世界上。这种架构比其他位置感知系统架构（如将虚拟信息附加到真实的对象上的增强现实）更有前途、通用、低成本和更现实。SpaceTag系统可以作为公共信息服务提供，是游戏，广告，城市指南信息等的公共平台，我们已经实现了原型。在本文中，主动SpaceTags另外提出。它们能够自主地与人类和其他SpaceTag进行交互，实现了交互式游戏，虚拟生物（SpacePet）等新的应用程序的主动SpaceTag的计算模型在这里描述。本文还将SpaceTag系统作为一个协同虚拟环境进行了讨论。它被认为是一个特殊的CVE，具有与真实的世界相同的空间/时间坐标。SpaceTags和SpacePets可以被视为虚拟空间中的对象和活动对象，但它们被投影到真实的世界上。用户可以通过这些对象相互通信。本文还介绍了这种通信是如何发生的。
A SpaceTag is a virtual object that can be accessed only from limited locations and time period. Users of the SpaceTag System can see and create SpaceTags using a portable terminal with a location sensor. We have categorized it as an overlaid virtual system, in which virtual objects are overlaid onto the real world based on time and space coordinates. This architecture is more promising, general purpose, low-cost, and more realistic than other location-aware system architectures like augmented reality that attaches virtual information onto real objects. The SpaceTag System can be offered as a public information service that is a common platform for gaming, advertising, city guide information, etc. We have already implemented a prototype. In this paper, active SpaceTags are additionally proposed. They are enabled to interact autonomously with human and other SpaceTags, realizing new applications of interactive games, virtual creatures (SpacePet), etc. The computation model of active SpaceTag is described here. This paper also gives a discussion by regarding the SpaceTag System as a CVE. It is a considered as special CVE that has a same space/time coordinates as the real world. SpaceTags and SpacePets can be regarded as objects and active objects in the virtual space, but they are projected onto the real world. Users can communicate with each other through these objects. This paper also describes how such communication occurs.
