You can use InsiteVR to add annotations to your 360 images. The annotations can be used to provide more context or label items in the image.
You can add annotations to your 360 images all within the web browser. This allows for simple and fast creation of VR experiences without downloading anything.
First, go to your project in InsiteVR and select "Start Presentation". If asked what you would like to present, select "360 Images".
Go to the 360 image where you would like to add the annotation and press the "+" button on the bottom right of the screen.
Select "Text Annotation" then type the text you would like to add to the image. Now use your mouse to place the annotation and click to save the link in that location.
