Examples of lying and standing transitions and results for their detection. a Example time series of the raw tri-axial accelerometer output for standing up and lying down transitions. A rapid change in acceleration for all three axes can be observed. b Output of the results for the transition detection algorithm. Values of the range of the y-axis above a predefined threshold determine if a transition has occurred. Visual observations are displayed in green and prediction by the algorithm in red (“up” corresponds to standing up and “down” to lying down)
