摘  要：混合现实工具的发展近年来十分迅速，而在混合现实场景下的虚拟内容的放置与交互方式取决于用户身处的情境。基于此，我们针对学校场景下，学生获取信息的应用场景，设计了一个具有情境感知功能的原型。在原型之中，系统将用户的状态划分为了行进、寻找目标和阅读信息的三个情境，并针对性的为这三种情境进行了内容的呈现。同时，在原型中，我们假定用户的信息已经被系统获知，并针对性的为其推送他需要的信息。我们针对这个原型开展了两次实验，并且在第一次实验之中选取了专业的设计、开发人员针对系统的优化提出建议。第二次实验之中，我们评估了系统的可用性和使用效率，并对比了具有情境感知功能的系统，不具有情境感知的系统和肉眼可见的传统媒介。

Abstract:The development of mixed reality is very rapid in recent years, and the placement and interaction of virtual content in mixed reality scenarios depends on the user's situation. Based on this, we designed a prototype with context awareness in a school scenario of students' getting information. In the prototype, the system divides the user's state into three situations: moving, searching and reading detail, and presents the contents respectively of these three situations. At the same time, in the prototype, we assume that the user's information has been known by the system, and push the targeted information to meet the users’ need. We carried out two experiments on this prototype, and in the first experiment, we selected professional designers and developers to propose suggestions for system optimization. In the second experiment, we evaluated the availability and efficiency of the system, and compared the system with context awareness, the mixed reality system without context awareness and the traditional media visible to the naked eye.
