Postrum II: a posture aid for trumpet playersDalgleish, Mathew,; Spencer, Steve,; Foster, Chris.; Spencer, Steve; Payne, Christopher (Linux Audio Conference, 2015-04-09)While brass pedagogy has traditionally focussed on sound output, the importance of bodily posture to both short-term performance and longer-term injury prevention is now widely recognized. Postrum II is a Linux-based system for trumpet players that performs real-time analysis of posture and uses a combination of visual and haptic feedback to try to correct any posture issues that are found. Issues underpinning the design of the system are discussed, the transition from Mac OS X to Ubuntu detailed, and some possibilities for future work suggested.
