  • Publication number: 20200081543
    Abstract: A method for generating at least one tactile pattern using a haptic feedback device (70) having an active space within which a user can move his finger (F) in order to feel the tactile pattern, the perception of the pattern being caused by the modulation of the mechanical excitation of the finger pad by an excitation element, the method having the steps involving: detecting (100) the position of the finger (F) in the active space; calculating (101) the speed of the finger, determining (102), for each detected position of the finger, an associated taxtel within a predefined grid of taxtels, each taxtel having an associated texture value that is dependent on the tactile pattern to be reproduced, each taxtel having its largest dimension less than or equal to 8 mm, generating (103, 104, 105), on the basis of the texture value associated with this taxtel, a control signal for controlling the excitation element, this excitation signal being dependent on the speed of the finger at least for the densest tactile pa

  • Patent number: 9547367
    Abstract: The The invention relates to a touch interface comprising a contact surface and means for vibrating the contact surface, said means being provided to generate standing waves in said surface. The contact surface includes at least one transparent portion forming a surface for seeing through the touch interface, and the vibration generating means include at least one rigid piezoelectric layer that is rigidly connected to the contact surface and disposed on the periphery of the transparent portion. The interface is characterized in that the at least one piezoelectric layer is disposed in a plane that is not parallel to the contact surface. The invention also relates to a display screen using such an interface, and to an electric appliance using such a display screen.
