description Method and apparatus for detecting an evoked potential in a physiological signal of a user, in response to the generation of a sensory stimulation signal played by a human machine interface intended for the user. The sensory stimulation signal is periodic and adjustable in frequency. For a given sensory stimulation signal, the frequency of the given signal is adjusted to a first frequency, and then a latency in the user's reaction between the moment the given signal is generated and the moment the evoked potential is detected when such detection occurs is measured. If the latency is lower than a threshold, information is stored according to which the first frequency is attributable to a sensory stimulation signal. Otherwise, the method is repeated with a second frequency in place of the first frequency, the second frequency being different from the first frequency.
