With the Interactive Object Info option you can have the AI Agent automatically trigger giving information on any target object automatically. You can then ask follow up questions. Note: As of E-Learning lab 1.2.4 you can also choose to show text labels automatically.
To get started, click on the "Interactive Object Info" checkbox and make sure "AI Agent Assistance" is checked as well
Next click "Edit" to open your model and make sure any child objects you want information on has a relevant name (i.e. Human_Heart on a human heart model). Can right click to rename. The name of the object is what will be sent to the AI for information (i.e. "Please tell me about the human heart")
Then, click the "Target" checkbox in the Projects tab to be able to trigger interactive information on that object
When you run the scene you can now use the highlighter tool to highlight the object and use either the 't' key (if in Desktop mode) or the RH A button (if using a VR headset, note this was trigger, but was changed to the A button as of 1.2.6) to trigger the AI Agent to give information on the chosen object. Use either the Right Mouse Button or RH Grip to toggle showing the highlighter. You can also ask follow up questions of the Agent by clicking either the '2' key or the 'B" button on the RH controller.
