i4 MEETING

Features
Read full description

Host a virtual meeting with i4 MEETING, where participants can attend the meeting using a browser, tablet, PC or even VR glasses. Choose an avatar and a name and join the meeting. You can then move freely around the VR world and see the avatars and names of all participants. When the meeting starts you can talk to other participants as if you were actually there. You can also upload your own 3D models (e.g. CAD) to present them. A range of i4 MEETING apps enables you to choose the degree of immersion. You decide how realistic the virtual meeting should be for you. The highest degree of immersion is achieved using VR glasses, which allow you to experience the virtual meeting very realistically. If you use a browser, PC or tablet you can participate in the meeting in the same way, but the degree of immersion is somewhat lower.
