Patent ID: 7961085

Claim:
A method for monitoring attentiveness during a manual control of a dynamic system, comprising: detecting deficiencies of control; and emitting warning signals, wherein said warning signals are caused to be constituted by a pair of vibrations of different frequencies (w 1 , w 2 ) in a surface of a steering wheel of a vehicle from oscillators arranged in or on the steering wheel in a physical-mechanical interface of said system between the person and a machine (PM), where the vibrations are caused to have such frequencies, amplitudes and durations that a Meissner corpuscles (MC) and a Pacinian corpuscles (PC) on inner surfaces of hands and fingers are activated when the hand of the person comes into contact with a control device (W) for the control of said system (V) and deficiencies in attentiveness are caused to trigger said vibrations and said vibration frequencies of said pair of vibrations (w 1 , w 2 ) lie in the interval 1-150 Hz and 150-500 Hz respectively.
