Ambulation assistance wearable device and corresponding method

An ambulation assistance wearable device, comprising:

• a support (2), configured to be removably attached to a body of a person in an attachment position;
• a power supply (3), anchored to said support (2);
• a light source (4, 41, 42), mounted on said support (2) and electrically connected to said power supply (3), said light source (4, 41, 42) being configured to emit a beam of visible light (5, 51, 52) towards the ground, at least at one front stepping point (6, 61, 62) to which the person has to move a foot to move forward along an ambulation direction (x-x);
• a sensor (8) configured to detect at least one control parameter (pc) identifying an ambulation condition;
• and
• a processing unit (9), configured to control activation-deactivation of said light source (4, 41, 42) as a function of said at least one control parameter (pc), said processing unit (9) being operatively connected to said power supply (3), said light source (4, 41, 42), and said sensor (8);
• wherein:
• said at least one control parameter (pc) corresponds to an angle or to a displacement measurement related to an instant position of at least one part of the body of said person, during ambulation;
• said light source is mounted on a second, movable support to change an orientation of a propagation axis of the beam of visible light and/or a position of said light source;
• said movable support is dynamically connected to a shaft of a motor
• said motor is operated by a control unit;
• said control unit is designed to receive measurement signals of the position in space of said light source or a change of said position, said control unit being further designed to generate a control signal for operating said motor as a function of said measurement signals of the position of said light source, said control signal being adapted to compensate for a change of the position of said light source.
