The invention relates to a method for the somaesthetic stimulation of at least one user (UT) for the purpose of collecting at least one electroencephalogram signal (EEG) comprising an evoked potential with a view to activating a brain-computer interface (BCI) based on somaesthetic stimuli applied to the user's skin. In particular, with the user positioned in an environment (ENV), the stimuli (STS) are applied to the environment by a transducer (HP), the user's skin being in contact with the environment and thus receiving the stimuli via the environment.
