My Research
I am doing research on usability and user experience at CURE, the Center for Usability Research and Engineering. My research topics include methods for measuring user experience, the evolving web and its implications, and the mobile user experience with its continued increase in mobile services.My research topics include methods for measuring user experience, the evolving web and its implications, the mobile user experience, and interfaces for autonomous and intelligent systems, in multiple contexts. User interfaces for such systems are not easy to accomplish, as their interaction possibilities are typically limited or even hidden as much as possible from the users. However, they are also characterised by a less-than-flawless operation (i.e., they are not perfect). In such sytem-breakdown situations, the user has to know what is going wrong, why it is going wrong, and how he or she can fix it without landing in a dangerous situation.
Dealing with (semi-) autonomous, intelligent systems is relevant specifically for the two application domains “assisted living” and “assisted driving”. In these specific contexts, specific user acceptance, usability and user experience challenges occur. For elderly users for example, the inexperience with technology, and sensory, physical and cognitive declines. In driving, the safety issues associated with interaction errors are not to be overseen.
