While in a session users have multiple options, depending on their current roles within the session.

The session Owner is the user who created the session. They join the session as Presenter.

The Presenter can navigate through the volume, change clipping planes and visualisations settings (rendering modes, level of detail rendering), and use the pointer and highlight tools to draw attention to any part of the volume. Everything the presenter does is shared automatically with all the attendees.

All other users join the session as Attendees. Attendees have no control over the volume. Their avatars (headset and controllers) are visible to all, and if using voice chat can be heard by all attendees, including the presenter. Attendees can also adjust their own personal visualisation settings based on their computer performance (e.g. increasing/reducing the rendering step size, changing between lab, floor or no environment), but otherwise have no power to affect what others see. Attendees can move freely within the VR space within the boundaries of their own local physical environment or use locomotion for more flexibility. Session participants can fly around by pressing the thumbstick on their right controller forward or backwards. To rotate themself in 30° steps, they can swipe the thumbstick to the left or right.

At any point an attendee can request Presenter privileges by clicking the A button of the right controller in VR. Non-VR participants can send their request by opening the context menu at their name in the Participant list of the Collaboration panel. When they do the current presenter is prompter to either accept or decline the request. If the request is accepted, they then have all the tools of the presenter. Note that the session Owner can reclaim presenter privileges at any time through the Collaboration panel in the arivis Pro VR desktop window. In VR this is possible with the Manage tool of the Collaboration tool set.

Attendees who join without a headset can also join the audio and navigate freely within the VR space using the normal mouse-based navigation tools and they appear as a headset to other attendees, but without controllers. All participants can send each other text messages via the chat section of the Collaboration panel. Participants in VR will see new messages as an automatically disappearing popup window in VR.
