Pressure Effects is an interactive lighting installation that uses the intensity of pressure, synchronously transforming the transferring of pressure into a spectrum of lighting effect on the floor – when viewers sit on or press the light installation, which is in the shape of a stool, the greater the pressure, the higher the intensity of light would be. In the meantime, the range of the projection on the floor will correspondingly become bigger as well, creating a more prominent effect. When the pressure is gone, the installation goes back to the default mode, emitting soft, dim light and a minimized projection.
