  • Haptic interface
    Patent number: 11921958
    Abstract: A haptic interface of the ‘mid-air’ type, including a control circuit, a plurality of ultrasonic transducers connected to the circuit, which includes a first set of transducers emitting at a first ultrasound carrier frequency and at least a second set of transducers emitting at a second ultrasound carrier frequency different from the first; the control circuit being configured for modulating the signals sent to the transducers in order to generate, with the ultrasound waves emitted by at least a part of the transducers of the first set, an acoustic pressure detectable by touch within at least a first focal region, and generate, with the ultrasound waves emitted by at least a part of the transducers of the second set, an acoustic pressure detectable by touch within at least a second focal region.
    Type: Grant
    Filed: November 26, 2021
    Date of Patent: March 5, 2024
    Assignee: COMMISSARIAT A L'ENERGIE ATOMIQUE ET AUX ENERGIES ALTERNATIVES
    Inventors: Fabrice Casset, Angélique Rascle
  • Virtual, augmented, or mixed reality device
    Patent number: 11474607
    Abstract: A portable virtual, augmented, or mixed reality device, including: a mount intended to be worn on a user's head; a display screen attached to the mount and intended to be arranged in front of one of the user's eyes; a plurality of ultrasound transducers attached to the mount; and a control circuit configured to control the display screen to display images, and the ultrasound transducers to generate, in air, at a distance from the mount, a pressure distribution detectable by the user's hand to obtain a haptic effect.
    Type: Grant
