Hotspot

Berlin hotspot embeds a popup to your overlay with an image or a video inside. Berlin hotspot now supports nine content types -- simple, HTML, Image-left, Image-top, video-top, image, video, audio, and iframe.

The hotspot is a button with a popup that presents extra information to visitors about what they’re seeing on a virtual tour.

The other type of hotspot you can add to your overlay is Pano Link. This hotspot allows you to move between rooms/panoramas, to join them into a combined virtual tour.
