Abstract: Systems and methods are provided to monitor a user body position and/or influence a user to change and improve body position, without causing the user to wake up. A personal audio output communicator is adapted to be positioned in close proximity to an ear of the user. A motion detector is adapted to attach to the user for generating a motion signal. A stimulus provider is adapted to receive the motion signal from the motion detector and to compare a motion signal value representative of the motion signal to a preset motion value. In response to the comparison, the stimulus provider transmits a user-selected stimulus and/or voice command stimulus to the personal audio output communicator.
