Abstract: The invention relates to a method comprising the steps of: establishing a personal user profile, representing the initial physiological conditions of said user, loading said personal user profile into said pause adviser system, by means of said pause adviser system establishing user stimuli on said output arrangement, by means of said pause adviser system establishing a fatigue level on the basis of: said reference data, said personal user profile, user input data obtained by said user input arrangement in response to said user stimuli, and sensor input data obtained from said sensor input arrangement, by means of a data processor, transforming said fatigue level into output advice data and communicating said output advice data to said output arrangement.

Abstract: The invention relates to a pause advice device comprising: a pause algorithm being adapted to receive input from the input arrangement, said input arrangement being adapted to provide information to said pause algorithm to start-up the pause advice device, said pause algorithm being adapted to receive a personal user profile from the input arrangement, said pause algorithm being adapted to provide user stimuli via said display means and/or via said audio source, said pause algorithm being adapted to receive response input from a user based on a users response to said user stimuli provided via said display means and/or via said audio source, said pause algorithm being adapted to provide an alarm signal via said display means and/or via said audio source, said alarm signal signaling preferred time for said user for resting according to said pause algorithm.
