5. The information processing device according to claim 3 ,

wherein the haptic data generating unit generates the haptic data based on the attribute information associated with the other virtual object different from the virtual object manipulated by the user.

6. The information processing device according to claim 3 ,

wherein the haptic data generating unit generates the haptic data based on both the attribute information associated with the virtual object manipulated by the user and the attribute information associated with the other virtual object different from the virtual object manipulated by the user.

7. The information processing device according to claim 1 ,

wherein the haptic data generating unit further generates the haptic data in accordance with a relative speed or a contact position between the virtual object in which the plurality of listeners is placed and the other virtual object.

8. The information processing device according to claim 1 ,

wherein the haptic data generating unit generates the haptic data based on a shock generation source that exists at a position away from the virtual object in which the plurality of listeners is placed.

9. The information processing device according to claim 8 ,

wherein the haptic data generating unit generates the haptic data based on a medium between the virtual object in which the plurality of listeners is placed and the shock generation source.

10. The information processing device according to claim 1 ,

wherein the haptic data generating unit generates the haptic data for the one or more haptic devices corresponding to one or more listeners among the plurality of listeners based on a coupling relation between the plurality of listeners.

11. The information processing device according to claim 10 ,

wherein the coupling relation relates to a propagation characteristic.
