E-Learning Lab uses the following hardware options by default:
'Desktop', 'Meta Quest Pro','Meta Quest 3','SteamVR','Quest 3 Client','Meta No Eyetracker','Vive Focus Vision','Varjo'
To use your own, such as a Projection VR configuration:
In the E-Learning Lab interface go to Options- Advanced and click on "Open mediaConfig.py"
Change LOCAL_VIZCONNECT = True
Now, any vizconnect file that is placed in E-Learning Lab\local_vizconnect_configs will be referenced. This includes a modifiable Projection VR configuration vizconnect_config_projection.py
For more on vizconnect, see this page in the Vizard documentation
