The virtually reality experience is no longer limited to bulky head gear with the advent of a new headset-free 8K high-resolution video projection system.

Some Japanese firms have come up with a headset-free VR entertainment experience that projects ultra-clear imagery, and they are trying to gauge its popularity with the public.

Along with other firms, NHK and affiliate partners came up with a VR attraction that takes people on a virtual tour of Tokyo, which was demonstrated at the National Museum of Emerging Science and Innovation in the city's Koto Ward on Tuesday for reporters.
