This past summer I had the opportunity to work for computer science PhD candidate Ryo Suzuki under the guidance of Tom Yeh of the computer science department. My task was developing printed circuit boards for experiments for human computer interaction (HCI). The goal was to create a surface which a magnet could be moved to create patterns, animations, display information and alerts. Below is an image of the coil array, dispersed on 4 layers. This allows for tighter resolution. By having over lapping coils, the magnet could be pulsed and moved in less discrete steps. The further the coils are apart, the more discrete each position appears, resulting in less smooth transitions, and increased current to attract the magnet from point A to point B.
