A novel concept of a wearable information appliance using context-based human-computer interaction

In healthcare environment, different kinds of automatic solutions have been created to monitor and track patients, for example near-field imaging and low-frequency RFID. The problem has been how to use the context-based data these systems produce and how to show the related information to the nursing staff. This paper shows how hospital data can be automatically transmitted to people using location information. The information is transmitted to a name tag that has wireless connectivity and touch screen with electric paper. This concept is piloted with a test application.
