This document discusses the development of a music player controlled by sensors. It explores existing music products for inspiration. Sketches show a sensor cap that fits on a speaker and detects touch, light, and sound to control the music. The device will use an Arduino and sensors to detect input and an open source platform to stream music. Prototypes of the sensor cap are being created to test interactions and work out technical challenges before user testing the system. The overall goal is to create an intuitive music player controlled by environmental sensors.
