In the world of musical performance, poor posture can lead to a poor performance, resulting in the conception of the Musician's Mirror -- a device that provides immediate audio and visual feedback to help musicians improve their posture, and subsequently, their technique.
The device is adaptable as every different instrument requires different body positioning. Musicians can select which parts of their body they'd like the device to track to create the presets for what they consider good and bad form. The Musicians Mirrors, for example, can detect whether a guitar player's arm is too high, or is a piano player's shoulders are hunched. If the device detects the musician has fallen into a bad habit, they will notify them through the accompanied app, or by noise.
