YOKE created an interactive and playful installation for the audience at TEDxCopenhagen 2013 to explore. A wall in the lobby served as a magical mirror, which revealed the thoughts of people passing by. Some thoughts were related to the talks, whereas others aimed to spark social interaction ("Give me a high give, and I'll tell you a secret!"). The installation sparked a lot of smiles, group photos, high-fives and new connections.
The effect was achieved through camera tracking, dynamic graphics generation and high resolution back projection.
