To improve people’s lives, human-computer interaction researchers are increasingly designing technological solutions based on behavior change theory, such as social comparison theory (SCT). However, how researchers operationalize such a theory as a design remains largely unclear. One way to clarify this …

Recommenders play a significant role in our daily lives, making decisions for users on a regular basis. Their widespread adoption necessitates a thorough examination of how users interact with recommenders and the algorithms that drive them. An important form of interaction in these systems are algorithmic …

This paper shows an overview of design practices of the XR-lab at the Amsterdam University of Applied Sciences, The Netherlands. Over the course of six years, interdisciplinary teams of students have delivered 55+ prototypes in virtual, augmented, and mixed reality for a variety of 40+ clients. As human-computer …

Children with cerebral palsy must perform daily exercise which is a tedious and energy consuming task. Exergames can make this routine more engaging, which can increase the compliance of the patient. This research explores the feasibility of an exergame device called the Squid Monster. The device is …

Voice intelligence is a revolutionary “zero-touch” type of human-machine interaction based on spoken language. There has been a recent increase in the number and variations of voice assistants and applications that help users to acquire information. The increased popularity of voice intelligence, however, …

AI ethics research has mainly focused on high-level principles and guidelines, and technical issues. This position paper argues that more attention should go to the practical and contextual aspects of designing AI applications and explores how living labs can contribute to the ethical design, development …

Behaviour Change Support Systems (BCSS), already running for the 10th time at Persuasive Technology, is a workshop that builds around the concept of systems that are specifically designed to help and support behaviour change in individuals or groups. The highly multi-disciplinary nature of designing …

This doctoral dissertation, anchored in the fields of Human-Computer Interaction (HCI) and design research, addresses the following primary research question: How can interaction design research contribute to stimulating physical activity in the office environment? This thesis makes several contributions …

Although many people have a positive intention to be more active, a key challenge remains to turn this intention into action. Social support as a motivational strategy can increase adherence in exercise and can be provided by relational agents as a substitute for human coaches. We first conducted an …

As an active form of meeting, walking meetings can be beneficial for office workers who often have a sedentary work routine. Despite their substantial benefits in terms of health, social interactions, and creativity, walking meetings are not yet widely adopted. Some key barriers limiting their social …
