If you are on campus you may be asked to take part. The students will go around with their laptops and Android devices (thanks to http://osdoc.cogsci.nl/) and ask for your input. Don't be shy! We will store all information anonymously, so don't worry about not being good at the task. The task should take around 5 minutes.
