“Equipped smart phone is firmly attached to a modified record, placed on a turntable, and used to sense a performers movement, resulting in a wireless sensing-based scratching method. The accelerometer and gyroscope data is wirelessly transmitted to a computer to manipulate the digital audio playback in real-time. The method provides the benefit of digital audio and storage, requires minimal additional hardware, accommodates familiar proprioceptive feedback, and allows a single interface to control both digital and analog audio. In addition, the proposed method provides numerous additional benefits including real-time graphical display, multi-touch interaction, and untethered performance (e.g “air-scratching”). Such a method turns a vinyl record into an interactive surface and enhances traditional scratching performance by affording new and creative musical interactions. Informal testing show this approach to be viable, responsive, and robust.”
