摘要：The Human-Computer Interaction field and all its concerning research areas are
constantly changing and evolving to achieve a better perception of computer systems
in general from the end-users¡¯ point of view. This area is getting more and more
importance when developing computer systems of any kind. In this moment we can
consider it as a mature field in which we can find very useful and ground breaking
research being conducted in such areas as design and development methodologies,
intelligent user interfaces, collaborative environments, virtual reality, to name but a
few. The desire to improve and innovate, coupled with the impulse to achieve
impossible challenges regarding human-computer interaction, makes this area
especially attractive.
