Conference and Mirror via Network
How Can I Collaborate with Others?

The Conference Mode enables multiple users who are physically remote to be together virtually in the same present4D VR-Suite project using internet synchronization. A laser pointer dot with their name underneath shows where each user is looking in the project. Audio can be submitted via voice over IP. Conferencing works for all VR-Suite compatible devices like PC, Mac, Smartphones and tablets, in both VR- and non-VR-Mode!
The Conferencing feature is ideal for guiding others through a VR scene, such as for investigative case reviews, pre-trial hearings, trainings, marketing presentations, virtual company tours, construction site consultations, product presentations, and much more.
Inside the Conference, the Leader is represented with a green symbol and all other attendees, the Followers, have a red laser pointer dot. There are two main commands:
Follow - This is used to bring a participant back to the group if a Follower has lost the others.
Lead - This is used by the Leader to bring all participants back to one Scene. The Lead command can also be used by a Follower to bring all others to his or her position to share what they are viewing.

Leader
The leader of a Conference can be recognized by the green laser pointer. The leader sees his own laser pointer as a green arrow, in case the Location contains Guided Tour HotSpots. All other participants see themselves as red arrows pointing toward the direction of the leader. This makes finding the leader easy.
Follower
All participants but the leader will be known as followers. The red arrow always points toward the leader which makes it easy to find him.

Mirror a View to a PC or Device
What is “Mirror via Network”?
Mirror the view of a mobile VR headset onto a PC, Mac, Tablet or Smart Phone to enable an audience to observe what is seen in the glasses. The devices can be connected via internet or local network (e.g. using a Wifi Pocket Router in Access Point mode). The observing device will start the conference, so it has to be started first.
1. Start the Observing Device (Desktop or Smart Device)
Choose Tab Settings
Choose Conference Mode: or .
Choose Mirror via Network:
Restart the VR-Suite
The PC will automatically start the Conference Mode!
Warning

In order to exit the mode temporarily: Crtl + w. No VR glasses must be connected. Otherwise the PC cannot be operated with the mouse.
To enable the mode temporarily: While starting a Conference use a Conference name which includes “@@”.
You can disable or enable the mode permanently only from the settings tab: Mirror via Network.

Screen Saver - Mirror via Network

How to configure a Screensaver
Technical Background
Device independent Conferences
The following devices can participate in a Conference:
PC in desktop mode
PC with Oculus Rift, HTC Vive or Windows MR headset
Samsung Gear VR
Oculus Go
Cardboard Android in VR mode
Cardboard Android without VR headset
Cardboard iOS in VR Mode

Mac OSX in non VR mode
Data and Traffic
To be able to start a Conference on multiple devices, you must install the VR-Suite onto all participating devices and download the required presentation. During a Conference, only the movement information will be transmitted, as the media data is already present on the device. This makes it possible to participate in a Conference even with a slow internet connection.
Online and Offline
The Conference can be started through the internet or in a local LAN.
Important note about Wifi & LAN & Firewalls
The firewall, anti virus tools or blocked ports can hinder the function of the Conference Mode. Smartphone HotSpots generally work well. Make sure you don’t accidentally use up your available data volume.

Tip
To use a Conference offline, use a high quality router without internet connection. This can lead to a more stable function during trade fairs or similar events.
