1. A system for providing feedback to a user of a walking aid to regulate gait, stance and/or activity irregularities, the system being configured to be installed on a walking aid comprising a frame, at least two wheels, two handles and wherein the frame comprises an intermediate supporting frame between the left and right handles of the frame, the system comprising:
a configuration of sensors for measuring at least one gait, stance and/or activity indicator comprising at least one of the step frequency, step size, step width, ground clearance, walking speed, amount of pressure on the walking aid, ground contact forces of user's feet, and/or toe-to-heel walking,
a user profile comprising user gait, stance and/or activity characteristics,
a configuration of at least one stimuli generating device configured to provide feedback to the user with a visual cue based on the measurements of the sensors and on the user profile,
wherein the visual cue is configured for projecting a first line on a ground plane perpendicular to a direction of motion.
