Claim 5:
6. An apparatus as claimed in claim 1, wherein the content for rendering comprises time-varying content, the method comprising using a combination of the user perception direction and the observation field of perception at a first relative time to define restricted content of the time-varying content for subsequent relative times, wherein the apparatus is further caused to:
use a combination of a user perception direction at a second relative time, subsequent to the first relative time, and the rendering field of perception to define content for rendering at the second relative time;
render in a first state at the second relative time any portion of the content for rendering that is not defined as restricted content and rendering in a second state at the second relative time, different to the first state, any portion of the content for rendering that is defined as restricted content; and
use a combination of the user perception direction at the second relative time and the observation field of perception to enable re-definition of the restricted content for relative times subsequent to the second relative time.
