Abstract

The invention relates to a virtual reality accessory comprising a headset (4), characterised in that it includes at least one control moment gyroscope (10) mounted on the headset (4) such as to even a torque in a particular direction on the headset (4), and a controller (12) which is connected to the control moment gyroscope (10) anti arranged to control same according to a control law in order to generate a haptic feedback linked to the movement of a user in a virtual reality simulation.

Claims

1. A virtual reality accessory comprising a headset, characterized in that it comprises at least one gyroscopic actuator mounted on said headset so as to exert a torque with a respective direction on the headset, a controller linked to said gyroscopic actuator being arranged to control it according to a control law in order to produce a haptic feedback related to the movement of a user in a virtual reality simulation.

2. The accessory as claimed in claim 1, comprising four gyroscopic actuators mounted on said headset so as to each exert a torque with a respective direction on the headset, the controller being linked to each of said gyroscopic actuators and being arranged to control them together according to respective control laws in order to produce a haptic feedback related to the movement of a user in a virtual reality simulation.

3. The accessory as claimed in claim 1, wherein the headset comprises an attachment portion for a virtual reality simulation device.

4. The accessory as claimed in claim 3, wherein the headset receives a virtual reality simulation device.

5. The accessory as claimed in claim 1, wherein the headset has the form of a mask.

6. The accessory as claimed in claim 5, comprising four gyroscopic actuators positioned substantially symmetrically in pairs relative to two axes of symmetry of the headset.

7. The accessory as claimed in claim 6, wherein the gyroscopic actuators are each positioned at a corner of the mask.

8. The accessory as claimed in claim 1, characterized in that the headset has a shell designed to be attached to the cranium of a user without covering the ocular region.

9. The accessory as claimed in claim 8, comprising four gyroscopic actuators positioned substantially symmetrically in pairs relative to two substantially orthogonal axes of symmetry of the headset.

10. The accessory as claimed in claim 9, wherein the gyroscopic actuators are positioned on the shell at a location corresponding substantially to a corner of a cranium.
