Roundme is a free online VR platform that allows users to upload 360 images to create their own VR tours, which can be eventually viewed on handheld devices or VR headsets. A suite of functions are available to make the tour as interactive and engaging. There is also no restrictions for the number of 360 pictures, termed Panorama, which can be added.
This tool shares many similar features with Google Tour creator, and is a suitable alternative subject to specific requirements. For example, if there is a need for sounds to be placed/played only at specific locations on each scene, and if there is a need to capture screenshots, which is a native function of Roundme. Educators may tap on these specific features for their classroom needs, and perhaps use them creatively to showcase teaching points, which is apparent only at specific viewing angles, or combined with some ambient audio clips.
