A Design of Framework for Aquiring, Processing, and Visualizing Mobile Contexts

Currently, the research about developing intelligent applications, which aware a user's context such as surrounding information including location and movement with mobile dervices, is active. To aware the context, the first step is to acquire contextual information. And then, what reactions are taken is determined by processing and visualizing the collected context. To do this, it is a prerequisite to aquire, process, and visualize comprehensive contextual information for developing intelligent contexe-aware application. However, current context-aware applications only utilize the context which is related to aware realtime situations on a single user. That is, the context-aware capability of them is limited. Therefore, this paper proposes design of mobile context visualization framework which 1) collects comprehensive context information and 2) visualizes the information with the appropriate disaply format. First, we summarize acquirable context from representative mobile platforms. And then, we design the context visualization framework to collect and visualize the context. This design includes architecture showing communication between the client to collect raw data and the server to process the data and display formats for each context. Finally, to show practicability and applicability of the design, we show a prototype of mobile context visualization framework, application and utilization case of the visualization framework.
