Computação Ubíqua Ciente de Contexto: Desafios e Tendências

Abstract

Ubiquitous computing defines a new paradigm in which devices with processing and com- munication capacity are embedded into everyday elements, providing services in a trans- parent way to users. It is possible to notice that this kind of computing has a strong connection with physical world features, as well as those presented by its users profi- les. In this way, if ubiquitous systems are capable of using as input relevant information about entities (e.g., people, places or objects) related to the application, they can provide services that are more appropriate, dynamic and optimized, increasing the user satisfac- tion and minimizing resource consumption, such as energy, processing, communication, among others. Such information is called context and represents the basic input element for context-aware computing. The goal of this short course is to discuss research trends on the ubiquitous context-aware field, presenting and analyzing the research performed on specific challenges. Such proposal presents interesting solutions to problems ranging from physical aspects of wireless communication to the design of applications available to the users.
