Abstract: Methods and apparatus of transmitting haptic data representative of a haptic effect are disclosed. Haptic device data representative of haptic rendering capabilities of a haptic rendering device is obtained. The haptic data is determined by processing received haptic data representative of the haptic effect according to the haptic device data to adapt a rendering of the haptic effect to the haptic rendering capabilities. The haptic data is transmitted to the haptic rendering device.

Abstract: Methods and apparatus of signaling/parsing data representative of a mapping between a haptic effect and one or more body parts of a body model targeted by the haptic effect are disclosed. The body model includes a first plurality of body parts, e.g., fingers, hands, phalanxes, head, and a second plurality of groups of body parts. Each group of the second plurality comprises one or more body part(s) of the first plurality. The signaling/parsing of the data comprises writing/reading, into/from a container, first data identifying the targeted body part with reference to one or more groups of the second plurality the targeted body part belongs to.

Abstract: Methods and apparatus of signaling/parsing data representative of a mapping between a body part of a body model targeted by a haptic effect and a haptic device comprising a set of haptic actuators the configured to render the haptic effect on at least a part of the body part are disclosed. The signaling/parsing of the data comprises writing/reading, into/from a container, first data representative of the body part and second data representative of a spatial distribution of the set of haptic actuators in a determined multidimensional space.

Abstract: Methods and apparatus of encoding/decoding haptic signal representative of haptic effect. The haptic signal is encoded according to a hierarchical representation, which includes a plurality of layers, a different hierarchical level being associated with each layer. The encoding of the haptic signal comprises the encoding, in the first layer, of a first set of base signals, which includes one or more base signals. First data representative of each base signal of the first set is encoded in this first layer, each base signal being represented in a determined space. Second data is encoded in the first layer in addition to the first data, the second data being representative of modulation of each base signal. Third data representative of the determined space is then encoded in a layer, different from the first layer, having a hierarchical level higher than a hierarchical level of the first layer.

Abstract: A method for controlling a mobile device—placed on a holder, comprising an interface plate configured to be touched by an object so as to control the device, and comprising at least two movement sensors configured to detect a movement of the device—comprises a) applying an object to the holder at a point of impact located outside the interface plate, the application of the object leading to a propagation of a vibration wave that propagates along the holder, toward the mobile device; b) detecting, with each movement sensor, the vibration wave at a detection time; c) comparing detection times detected by each movement sensor, respectively; d) estimating a position of the point of impact on the holder, depending on the comparison carried out in c); and e) generating a control signal of the mobile device depending on the position estimated in d).

Abstract: A haptic device, for interaction with virtual reality or augmented reality systems, including a fixed body configured to be worn on a finger of the hand, and a movable body associated with the fixed body and actuated by a motor means; the device includes a flap associated with the movable body and having a convex contact surface; the movable body being movable with respect to the fixed body so that the contact surface moves from a position that is spaced from the fingertip to a position of contact with the fingertip.

Abstract: A touch-sensitive interface has a contact surface that is able to be touched by an effector (e.g., a finger). The interface includes actuating transducers (e.g., piezoelectric transducers) allowing a standing flexural wave to be formed, in a resonant mode, extending over the length of the slab. The interface includes a detector for measuring the amplitude of the wave, and a detecting circuit for determining an attenuation signal, when the contact surface is touched by an effector. It includes a processing circuit for estimating a magnitude of the force exerted by the effector on the contact surface.

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
