A method comprising: rendering via a head mounted apparatus virtual visual content to a user, for consumption by the user, wherein a real-time change in orientation of the user in a real space causes, via a mapping between the real space and a virtual space, a corresponding real-time change in orientation of a virtual user in the virtual space and a corresponding change in the rendered real-time virtual visual content; in response to a determination that a user is no longer consuming time-evolving virtual visual content, rendering to the user not using the head mounted apparatus, a real-time notification in response to detecting an event programmed by the user in time-evolving real-time virtual visual content consumable by the user, wherein the real-time notification draws the user's attention to relevant virtual visual content that is available for consumption by the user and directs a user to adopt a particular orientation in a real space that depends upon a mapping between the real space and the virtual space to orient the user with respect to the virtual space (20,90) for restarting user consumption using a secondary apparatus, of the real-time virtual visual content, wherein after restarting consumption via the secondary apparatus, a subsequent real-time change in orientation of the secondary apparatus in the real space causes, via the mapping between the real space and the virtual space, a corresponding real-time change in orientation of a virtual user in the virtual space and a corresponding change in the rendered real-time virtual visual content and wherein determination that a user is no longer consuming virtual visual content consists of one or more of: determining that the user has removed the head-mounted apparatus, determining that the head-mounted apparatus is outside a defined portion of the real space used for rendering virtual visual content, determining that the user is outside a defined portion of the real space used for rendering virtual visual content, determining that the user has switched off visual rendering of the virtual visual content. rendering via a head mounted apparatus virtual visual content to a user, for consumption by the user, wherein a real-time change in orientation of the user in a real space causes, via a mapping between the real space and a virtual space, a corresponding real-time change in orientation of a virtual user in the virtual space and a corresponding change in the rendered real-time virtual visual content; in response to a determination that a user is no longer consuming time-evolving virtual visual content, rendering to the user not using the head mounted apparatus, a real-time notification in response to detecting an event programmed by the user in time-evolving real-time virtual visual content consumable by the user, wherein the real-time notification draws the user's attention to relevant virtual visual content that is available for consumption by the user and directs a user to adopt a particular orientation in a real space that depends upon a mapping between the real space and the virtual space to orient the user with respect to the virtual space (20,90) for restarting user consumption using a secondary apparatus, of the real-time virtual visual content, wherein after restarting consumption via the secondary apparatus, a subsequent real-time change in orientation of the secondary apparatus in the real space causes, via the mapping between the real space and the virtual space, a corresponding real-time change in orientation of a virtual user in the virtual space and a corresponding change in the rendered real-time virtual visual content and wherein determination that a user is no longer consuming virtual visual content consists of one or more of: determining that the user has removed the head-mounted apparatus, determining that the head-mounted apparatus is outside a defined portion of the real space used for rendering virtual visual content, determining that the user is outside a defined portion of the real space used for rendering virtual visual content, determining that the user has switched off visual rendering of the virtual visual content. determining that the user has removed the head-mounted apparatus, determining that the head-mounted apparatus is outside a defined portion of the real space used for rendering virtual visual content, determining that the user is outside a defined portion of the real space used for rendering virtual visual content, determining that the user has switched off visual rendering of the virtual visual content.
