Lahti Light Well is an interactive lighting installation designed by Reija Pasanen (Studio Lux Nova) and Marjut Kauppinen. It is located on the central square in Lahti/Finland. The installation resembles a water Well, with undulating blue light as a background, which responds to people walking on top of the Well with white waves.
Visible was commissioned to create interactive content and a custom motion tracking algorithm, which is capable of tracking people on a dynamic background.
