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 …

Purpose/Objective: Most dose-escalation trials in glioblastoma patients integrate the escalated dose throughout the standard course by targeting a specific subvolume. We hypothesize that anatomical changes during irradiation may affect the dose coverage of this subvolume for both proton- and photon-based …

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 …

Fysieke inactiviteit is verantwoordelijk voor gemiddeld 1-3% van de nationale zorgkosten (World Health Organization, 2019). Volgens het Rijksinstituut voor Volksgezondheid en Milieu is te weinig bewegen een van de redenen dat de Nederlandse zorgkosten van 84 miljard in 2018 naar 174 miljard in 2040 zullen …

Background and purpose: Automatic approaches are widely implemented to automate dose optimization in radiotherapy treatment planning. This study systematically investigates how to configure automatic planning in order to create the best possible plans. Materials and methods: Automatic plans were generated …

Digital Behavior Change Interventions (DBCI) have a pivotal role in reducing lifestyle-related illness, absenteeism, and healthcare costs. Current challenges in designing DBCI are appropriately tailoring interventions and finding new forms of delivery. In this exploratory work, we present the design …

Sensor platforms can benefit from the incorporation of polymerbrushes since brushes can concentrate the analyte near the sensor surface. Brushesthat absorb acetone vapor are of particular interest since acetone is an importantmarker for biological processes. We present a simple procedure to synthesize …
