Control a Smartphone with 3D Printed Pipes

Disney Research is at it again. We all know that they have an infatuation with 3D printing. This time they have created passive smartphone applications which allow users to interact with their phones via their phone's own sound. They went on to 3D print various sizes and shapes of tubes which are used to alter the sound coming from the phone prior to it being sent back to the phone's microphone. The phone then is able distinguish the sound and obey a pre-programmed command. More information on this story may be found here: http://3dprint.com/65250/3d-print-control-smartphone/
