abstract

  • This paper reports our study of the distortion of the Magnetic North Vector in an office environment, which affects the use of commercial-grade Inertial Measurement Units (IMUs) for orientation tracking in a 3D hand motion tracking interface. The study includes data collected for 30 days to analyze the effect that may occur in terms of error and consistency. The Magnetic North Vector is one of the data sets used in orientation correction algorithms to reduce the bias offset error in IMUs. A non-ferromagnetic frame was made to define 125 points inside a cubic space in an office. Data was recorded for 30 days and analyzed to define the variation of errors. Experiment results show that the metal from a desk creates a magnetic distortion. In some areas the deviation of the Magnetic North Vector is severe and the amount of variation error is not uniform.
