Abstract:

Advanced electronic instrumentation and sensor signal processing in Input Devices for Musical Expression must meet several requirements: they should be accurate, reproducible, monotonic, and robust. Despite these demanding design requirements, a large number of input devices are currently being developed in a Do-It-Yourself manner using simple sensing techniques. The aim of this thesis is to raise awareness of the limitations of this approach. As a solution, we propose state-of-the-art engineering tools to improve the sensing design: use of specialized sensor technologies, better electronic instrumentation, coherent calibration and data regression methods, and advanced signal processing through the sensor fusion filters.
