Dan Gärdenfors is Head of User Experience Research at TAT, a Swedish software and design company. TAT was founded on a passion for developing visual experiences on digital devices through the combination of aesthetics and technology.

Gärdenfors spends his time in the TAT Innovation team, exploring emerging user interface paradigms such as augmented reality, stereoscopic 3D graphics and multi-sensor interfaces. This work is often visualized as films or implemented as cutting edge demos and prototypes. After more than ten years as an Interaction Designer, Dan still enjoys experimenting with all types of playful and alternative user interfaces, such as audio games and digital pen and paper technology.
