Lennart Nacke

Director of the HCI Games Group

Dr. Lennart E. Nacke is an Associate Professor for Human-Computer Interaction and Game Design in the Faculty of Arts at the University of Waterloo. He is working on projects that deal with the cognitive and emotional side of playing games. His goal is to describe, analyse and have computers and machines react to the thoughts and feelings you have when you are fully engaged in playing a video game. With this research we can start understanding the effects of video games (positive and negative). Using body sensor technology, for example sensors for brainwaves, heart rate, or muscle tension, Dr. Nacke taps into some of video gaming’s most motivating features to improve our physical fitness and mental wellbeing. His research is funded nationally and internationally and his publications have won best paper honourable mention (awarded to the top 5%) and best paper awards (awarded to the top 1%) at the premier human-computer interaction conferences CHI 2011 and CSCW 2012. He also writes blog articles for the online magazine Gamasutra via his personal blog.
