Abstract
An ambulation assistance wearable device, and related method, includes a support to be removably attached to the body of a person; a power supply anchored to the support; a light source mounted on the support and electrically connected to the power supply, which is configured to emit a beam of visible light toward the ground; a front stepping point where the person moves the foot to generate a bright spot in that point and move forward along an ambulation direction; a sensor that detects at least one control parameter identifying the ambulation condition; and a processing unit connected to the power supply, the light source and the sensor, which controls the activation-deactivation of the light source as a function of the at least one control parameter. The control parameter corresponds to an angle or a displacement measurement related to the instant position of a part of the body during ambulation.
