A device for providing the illusion of motion consists of at least two movable parts for stimulating the vestibular sense and the kinaesthetic sense of a user independently from each other. A moving headrest is provided for stimulating the vestibular sense of a user and a moving armrest is provided for stimulating the kinaesthetic sense of a user.

Haptic chair for motion simulation

A method and device for controlling at least one force-feedback device associated with at least a part of the body of a user. As to control the user's experience of motion and movements induced by the displacement(s) of the force feedback device(s) following operations are performed: [a] determining a speed value of a movement of the at least a part of the body according to at least a parameter representative of the displacement of the at least one force-feedback device, the movement of the at least a part of the body being induced by the displacement of the at least one force-feedback device; [b] comparing the determined speed value with a threshold speed value as to determine whether the displacement of the at least one force-feedback device is perceived by the user; and [c] controlling the at least one parameter according to the comparison result.

Method and device for controlling a haptic device

In order to generate force feedback data for a haptic device for providing simulated six degrees of freedom movement, a three dimensional acceleration component corresponding to the movement to be simulated is determined, a three dimensional velocity component corresponding to the movement to be simulated is determined and control signals for controlling at least three force feedback devices are determined, wherein each of the three force feedback devices provides three dimensional force effects to a fixation point associated to each of it, the three force feedback devices being arranged at defined positions with regard to each other, and the three fixation points define a geometric plane.

Method to render global 5 DoF motion effect with multiple local force-feedback

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. A second step involves deducing a three-dimensional force vector (formula (III)) from the linear acceleration vector (formula (I)) and linear velocity vector (formula (II)), said force vector being predetermined by a linear combination of said linear acceleration and velocity vectors, the corresponding force being applied via the haptic interface substantially at the physical point of contact. The invention also relates to a device for simulating movements of a vehicle.
