The device includes an ultrasound source for emitting an ultrasound transmission signal and an ultrasound receiver for receiving a corresponding ultrasound signal reflected by an obstacle, a control module for measuring a time of flight between emission of the ultrasound transmission signal and reception of the corresponding ultrasound signal reflected by the obstacle and calculating, on the basis of the aforesaid time of flight, the distance at which the obstacle is located. The device comprises an inertial sensor, in particular an acceleration sensor, designed to measure acceleration of the foot along three axes, and a control module configured for enabling operation of the ultrasound source if the aforesaid acceleration values measured by the inertial sensor respect a given condition for enabling measurement of the time of flight."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Wearable obstacle-detection device, and corresponding method and computer program product","description":"A device for detecting obstacles that is wearable by a subject, for example integrated in an item of footwear.
