A hand-mounted device is adapted to be worn on a hand of a user and includes an ultrasound transducer and a contact sensor. The ultrasound transducer is configured to emit an ultrasound haptic. The contact sensor is configured to detect a sensor value. A processor is configured to obtain a real position of the hand-mounted device to determine a virtual position of a virtual hand in the virtual world and to determine a virtual distance between the virtual hand and a virtual object in the virtual world based on the virtual position. The processor is configured to determine the hand of the user is open based on the sensor value and in response to the virtual distance being smaller than a contact distance and the hand being open, enable the ultrasound transducer to emit the ultrasound haptic to the finger."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Hand-free haptic feedback system and method","description":"A display device is configured to display a virtual world.
