While it's already changed the way we watch television and play games, the explorative potential of VR is the next big thing. In 2016, Greenpeace teamed up with Alchemy VR to create an immersive experience of David Attenborough's Great Barrier Reef Dive, where users could virtually explore the underwater world of the coral reef alongside him. Similar tech companies have created the Grand Canyon Experience, allowing users to take part in a virtual kayak tour through the national park. There's also Augmented Reality which takes these virtual experiences one step further, using force and vibrations to imitate different sensory experiences. While we're not convinced it'll ever beat the real thing, it does allow people to travel to places that would otherwise be inaccessible.
