Using water projection as a medium for interaction.

Description

Obscura is an interactive installation that combines the input of multiple users to create a collaborative projection.
Using neopixel strips, we backlight a solution of liquid that suspends magnetically charged ferrofluid to achieve the projection. Participants can create ripples on the solutions surface by moving modified servo motors with Rare Earth Neodymium magnets attached to them. When the magnets move closely under the liquid they attract the ferrofluid and create a disruption in the solutions surface.

The driving force behind Obscura is the interaction between users. Although the end result is a collaborative projection, the project is centered on the ways in which people connect to and influence one another. Light is used as a form of communication as users respond to one another’s neopixel and movement decisions.
