Teamwork between humans and computer agents has become increasingly prevalent. This paper presents a behavioral study of fairness and trust in a heterogeneous setting comprising both computer agents and human participants. It investigates people’s choice of teammates and their commitment to their teams in a dynamic environment in which actions occur at a(More)
Many people sincerely believe that it would be good to make lifestyle choices that have a positive effect on their own health, the social viability of their communities, and the longterm quality of the environment. Yet these same people often fail to act in accordance with these intentions. In this paper, we draw attention to the fact that people's failure(More)
Autonomous e-coaching systems have the potential to improve people’s health behaviors on a large scale. The intelligent behavior change support system eMate exploits a model of the human agent to support individuals in adopting a healthy lifestyle. The system attempts to identify the causes of a person’s non-adherence by reasoning over a computational model(More)
Decision making has since long been an area of interest to scholars from all kinds of disciplines: psychology, sociology, economics and more recently, computer science. A lot of research focuses on finding, isolating and formalizing the factors that are involved in decision making processes of both humans and software agents. The Colored Trails (CT)(More)
Autonomous e-coaching systems offer their users suggestions for action, thereby affecting the user’s decision-making process. More specifically, the suggestions that these systems make influence the options for action that people actually consider. Surprisingly though, options and the corresponding process of option generation—a decision-making stage(More)
This paper is concerned with the ‘rights’ of autonomous agent systems in relation to human users or operators and specifically addresses the question of when and to what extent an agent system may take over control from someone. I start by examining an important ethical code of conduct for system designers and engineers and argue that one would do well to(More)
Coaching practices are rapidly changing due to technological advances in the area of pervasive computing: the behavior of coachees can be monitored real-time, and coaching can be remote or even fully automated. The movement towards autonomous e-coaching systems holds promise for improving self-management, but also gives rise to questions about the(More)
The ongoing digitalization and automation of coaching practices is rapidly changing the landscape of coaching and (health-related) self-improvement. The introduction of a new class of support technologies— “e-coaching systems”—promises to deliver highly personalized, timely, around-the-clock coaching in a wide variety of domains and to a broad audience.
