  • Haptic system for establishing a contact free interaction between at least one part of a user's body and a virtual environment
    Patent number: 9760166
    Abstract: A haptic system for establishing an interaction between at least one part of the body of a user called stimulation zone and a virtual environment comprises means for estimating the position of the stimulation zone; means for emitting, toward the stimulation zone, at least one flow rate-controlled air jet, the air jet being emitted at a point of emission and its flow rate being determined as a function of the estimated position of the stimulation zone in space and of the characteristics of the virtual environment; a robotized structure controlled so as to move the point of emission of the air jet so that said point of emission remains at a constant distance from the stimulation zone.

  • Method for simulating specific movements by haptic feedback, and device implementing the method
    Patent number: 9558676
    Abstract: The invention relates to a method for simulating the movements of a virtual vehicle, a user being in physical contact with a simulator including a force-feedback haptic interface, wherein said physical contact corresponds to at least one physical point of contact between the haptic interface and the body of the user that is representative of a virtual point of contact between the user and the virtual vehicle. Said method comprises at least two steps. A first step involves determining a linear acceleration vector (formula (I)) and a linear velocity vector (formula (II)) at the virtual point of contact between the user and the virtual vehicle, said vectors being representative of the movement of the vehicle at said point.
