This year’s ACHI, the International Conference on Advances in Computer-Human Interactions, featured two papers of different current research topics of my group. Linda and Tabea presented their preliminary results in analyzing the requirements of supervisors when visualizing work load and emotion data in air traffic control. Our friends from the media psychology at Chemnitz University of Technology presented their joint user study on the effectiveness of different hierarchy visualization techniques. In addition, this paper actually won the Best Paper Award of the conference.
