Context compass

Abstract

We present an easy and natural method for accessing contextual data shown on an electronic map in a wearable computer. The information is stored as virtual objects in a known network database. The objects are retrieved from a point of interest database and visualized on a head-worn display of a wearable computer. Our method uses the familiar compass metaphor to present information in the real world. Any object visible on the map can be activated simply by looking at it. Only the objects belonging the user's current context are shown. The process is composed of four parts: a point of interest database, the user accessing the database, a user interface, and content viewing. In this paper, all these parts are presented.
