Responsive Lines
Interactive Poster, 2018
Responsive Lines is an interactive poster that follows users' hand movements. A motion tracking device is needed to activate this poster. This poster consists of numerous cube units, mapped with the same graphic pattern. The cubes react to a user's finger movements in real time so that they can manipulate this poster as if they are playing the piano. The cubes function as virtual piano keyboards, which can recognize up to ten fingers' movements. When a finger is almost to the end of the range that the machine can track, the cubes become very bright, and when the position gets lower, the cubes get darker.

This poster questions the conventional notion of poster form, which usually has static images so that it has only one direction of communication with viewers. By looking at afterimages caused from a slight time difference between the machine and users' movements, they can recognize the poster as a living mirror.
