摘要：In recent years, there have been many efforts at research towards obtaining the simple and natural use of computers, with interfaces closer to the user. New visions such as that of the Ubiquitous Computing paradigm emerge. In Ubiquitous Computing the computer is distributed in a series of devices with reduced functionality, spread over the user's environment and communicating wirelessly. With these, context-aware applications are obtained. In this paper we present an approach to the classroom context by identification process using RFID technology, as an implicit input to the system. The main goal is to acquire natural interaction, because the only requirement for the user (teacher or student) is to carry a device (smart label), identifying and obtaining context services. Some of these services and the mechanisms that make them available are described here, together with a scenario of their use in the classroom.
