did anyone try those cardboard glasses from Google?
I did. the undoubted advantage of Cardboard is the low price of the necessary equipment. Disadvantages - limited opportunities for interactive interactions with the virtual environment and moving only at specified points.
the most advanced technology is HTC Vive. The user interface here can be based on a smartphone with glasses or a laptop with a full-featured VR helmet. The main difference from the above-mentioned solutions is the controllers, which allow the user to interact freely enough with the virtual environment and arbitrarily move in space. In more advanced complexes of VR controllers, there can be more, respectively, greater involvement in the environment.
I heard the user can select the textures and colors of wallpaper, ceilings and walls in real time, change the weather outside the window, get a tactile response when opening doors, kitchen doors, and can move furniture at their discretion.
