We recently launched a in browser 360 / VR experience and it was a lot of fun exploring this new way of UI/UX design and technology. We will write a blog about how we achieved this later.
Most fun we had with creating interactive hotspots. It works by selecting it by focussing with a centered dot on the hotspots. Hold it and a progress bar will show you how long you have to hold it to open. It works really intuitive and is fun to use. Tested it with different users and everyone instantly understood how to interact.
