Hotspots are definable, interactive areas within the panorama. When the user’s mouse rolls or hovers over these hotspots, the user is presented with a clickable area of the image that may link to a webpage, image, movie, or anything else that can be hyperlinked. Hotspots can also be used to pop up blocks of information.
Hotspots presented on a touch device are activated when the user taps on the area of interactivity (which is usually visually marked).
A point hotspot indicates a single point of interactivity.
A polygon hotspot allows you to draw a custom shape using as many points/handles as necessary. The area within the shape is interactive.
