If you think watching World Cup on a big screen is novelty, Japan is going to awe you with their technologies. They intend to project holographic soccer matches worldwide on stadiums so that fans can watch them as if they are on location. However, you will need to wait until year 2022 (and if Japan wins the bid to host World Cup) for it to happen.
Not only Holographic technology, Japan also showcased Augmented Reality (which Singapore has started to do so this NDP) and also a universal translater that allows people from all walks of life to communicate with one another. Watch this video. Hopefully, Fifa officials are interested in these technologies.
