The digital world penetrates the real life space more and more, enhances analogue devices and merges with their functions. Further more the things are fully replaced through their digital equivalent, partly unjustified and underestimated. We questioned ourselves, what if the strong features of physical artefacts could also be included in a digital enhancement of things?
During the short-term project Analogies in the Digital I developed Scale. Scale is an analog input device, able to control a variety of things.. e.g. light.
The more you push the two free movable spheres apart, the brighter gets the light. Push them back together and the light fades. It's like pinch to zoom but with haptic feedback.
With the four built-in magnetic sensors it can sense and calculate the position of the two magnetized high-grade steel spheres and map them to a range of values which can be used wherever an input device is needed. They are covered under a black fabric to make the interaction feel nice and provide a smooth experience when pushing them around. The underlaying surface, which consists of multiple layers of acrylic resin, is designed to support the user input. The top layer is oval-shaped and acts like a guide to ensure an easy handling, even with one finger, and provide a user-friendly touch base. It also holds the four magnetic sensors. The second layer in the middle, which acts as the surface for the spheres to slide on, is teflon-coated and very thin. The lower level is holding the sensor cables, the magnetic parts and provides the opening for the main flat ribbon cable.
