A system (1) for controlling assistive technologies, provided with at least one assistive tool (2), for users suffering from movement and/or communication disorders, is described. Such a system (1) comprises an electronic communication interface (10), at least one biometric sensor (11), a calibration module (12) and a processing unit (13). The electronic communication interface (10) is configured to present the user with a plurality of sensory stimuli associated with commands and/or pieces of information that the user may want to select and/or to provide. The at least one biometric sensor (11) is adapted to be applied to the user to detect at least one biometric activity of the user and to generate a respective biometric electrical signal (SB, SBc, SBr) representative of the biometric activity detected. The calibration module (12) is configured to record, in an initial system calibration step in which the users biometric activity is a voluntary biometric activity conventionally considered as indicative of the users will to respectively select a command and/or a piece of information, one or more signal characteristics CS associated with the biometric electrical signal SBc detected in the presence of said at least one voluntary biometric activity. The processing unit (13) is configured to recognize, based on a comparison between the biometric electrical signal detected SBr and the one or more signal characteristics CS recorded, the voluntary biometric activity of the user and the related command and/or piece of information that the user wants to select, upon a sensory stimulus perceived. The processing unit (13) is also configured to provide control signals (SC1, SC2) both to the electronic communication interface (10) and to the assistive tool (2), based on the recognition of the users will to select. The electronic communication interface (10) is configured to present the sensory stimuli based on the at least one presentation control signal SC1, if present, and to p
