Human-Computer Interaction topics have been previously used to motivate and attract students to the field of Computer Science. However, as students are growing up in contact with several interactive computational devices, one could suspect that they already possess an empirical, informal knowledge about the quality of some types of human-computer interfaces. In order to test this hypothesis, we developed a Game Design Workshop to be offered to high school students. Based on the results of its first offering, we identified that issues related to displaying the game status and score, response time of controls and graphical and sound features were quite relevant to students. Students added additional features to solve those issues in a spontaneous way. An analysis of the developed games indicates that students had to learn and apply new concepts related to programming in order to implement the additional features. © 2013 ACM.
