Two high school students - Susanna and Matti - joined the UX Lab for two weeks from 4.6. to 15.6. for their summer traineeship. Under the supervision of Joni Rajala and Mikko Rajanen they designed, developed, and usability tested a game while learning about usability, user interface design, information processing science, and research. They accomplished successfully all the tasks that were assigned to them and gathered valuable research data.
