Understanding and Changing Behavior [Guest editors´ introduction]

The goal of this special issue is to contribute to the advancement of ubiquitous information societies, where computers and humans are part of the same ecosystem. One crucial property of entities living in the same ecosystem is that they mutually influence and affect each other´s behavior in a variety of ways. This special issue, organized as a follow-up to the Second International Workshop on Human Behavior Understanding, investigates several domains where such mutual influence is attempted through human behavior analysis.
