EVERY aspect of AVR is bespoke and can be controlled by the end user from where and when information is shown to them to what goes into their own 'World Space'. These spaces could be shared with others to show each other there dream contemplation spaces and thus provide valuable data. The amazing aspect of AVR is the fact the user IS creating the spaces, although initially the personal space will be created from bits and bobs chosen from 'premade' spaces they could in theory add more spaces, objects and such as time goes on via a dedicated platform.
The experience as a whole SHOULD emphasise as many sensory inputs as possible such as Audio via multiple channels of discrete audio played back via an omnidirectional device such as a headset. Physical interaction is possible with objects via phone front camera tracking and is a potential future feature.
Users will enter these 'worlds' via their mobile device or HMD and treat these spaces as a gateway / window. The advantage of AVR over a purely Virtual Reality is the user can at all points re-enter the real world and still see digital overlays in there own real world space if they so wish.
AVR is about contemplation and user experience first.
