A gesture-recognition system for a digital-pen-like device, envisages: at least one motion sensor to provide at least one motion signal indicative of movements of the digital-pen-like device; a gesture-recognition signal processor, coupled to the at least one motion sensor to process the motion signal and to implement a plurality of gesture recognition algorithms based on the motion signal, each of the gesture recognition algorithms being configured to recognize a corresponding gesture performed by a user of the digital-pen-like device; and a controller coupled to the gesture-recognition signal processor and transmitting gesture-recognition data indicative of a recognized gesture towards a host apparatus, with which the digital-pen-like device is associated.
