This paper describes Ivy, an office chair that represents sitting time of an office worker through growing ivy strands. The longer one sits, the more strands will grow onto the chair. By means of a qualitative interface called Ivy, we illustrate a design approach that is currently underrepresented in …

The Challenge Me intervention aimed to indirectly involve parents in a school-based intervention, by challenging primary school children to perform physical activity (PA) and nutrition-related activities with their parents.

In this paper, we present and discuss Ivy, a critical artifact offering a novel design perspective on interventions that aim to reduce sedentary behavior in office workers. Ivy is an interactive office chair that represents the amount of sitting time through growing ivy strands. Using the matrix of common …

The Office Jungle is an experimental office environment designed to make offices more "wild". Through this demonstration and associated design vision, we make a first attempt to reflect on and to define what characterizes wildness and how it could empower people in more playful and active lifestyles, …

Non-professional runners make extensive use of consumer-available wearable devices and smartphone apps to monitor training sessions, health, and physical performance. Despite the popularity of these products, they usually neglect subjective factors, such as psychosocial stress, unexpected daily physical …

Within this study the aim is to measure running workload and relevant running technique key points on varying cadence in recreational runners using a custom build sensor system ‘Nodes’. Seven participants ran on a treadmill at a self-chosen comfortable speed. Cadence was randomly guided …

There is increased interest in reducing sedentary behavior of office workers to combat the negative health effects of prolonged sitting. Walking meetings offer a promising solution to this problem as they facilitate a physically active way of working. To inform future development of technologies supporting …
