Wolfgang Kahler's vibrational display explores a unique method for creating visual output through electrical signals. The device translates the movement of an array of tiny motors into a series of mirrored disks which vibrate to soften and distort the reflected image. The modular mechanism consists of a vibrating motor affixed to a length of narrow-gauge wire with a piece of mirrored acrylic attached to the other end. The wire itself is mounted to a sheet of neoprene—holding the assembly securely while not dampening vibration. The amplitude of vibration is highly variable—affected by the diameter and length of the wire, the frequency of the motor, the mounting point, and the weight of the attached parts. The mirrored surfaces allow the viewer to perceive a relatively slight vibration. However, increasing the vibration can produce more extreme effects.
In further iterations, this prototype could evolve into a more complex installation, on a larger scale and with more reactive features, but its primary goal is to examine alternative modes of feedback. As objects become increasingly active purveyors of information, LEDs and LCDs can be challenged as sole means of visual communication. This more physical and highly tangible medium offers a refreshing and surprising departure.
