position 5320 from the reference gaze position process 6458 determines whether the displacement exceeds a predefined displacement threshold u03b4 if so the current gaze position becomes the reference gaze position process 6470 and a control message containing the new reference gaze position together with the corresponding frame identifier is formed process 6472 otherwise if the displacement is insignificant being less than u2014 or equal to u2014 u03b4 process 6474 generates a message containing the corresponding frame identifier and a null gaze position indicating that a frame data block stored in the content buffer 5230 may be displayed according to a previous view region definition the control message formed in process 6472 or process 6474 is transmitted process 6478 to augmented content selector 5210 due to tracking latency of the virtual reality headset a minor shift of the cyclic frame number may be needed fig6 illustrates processes 6500 performed at augmented content selector 5210 residing in the routing facility 5620 a new gaze position 5320 and a corresponding cyclic frame number 5310 fig5 are received process 6510 from refresh module 5820 of the remote content controller 5640 fig5 fig5 process 6540 selects process 6560 if the new gaze position is a null position otherwise process 6550 is activated to generate and retain a new view region definition which would overwrite a current view region definition the new view region.
