There are more uses for augmented reality glasses than just taking calls and viewing maps. Imagine if your pair of Google glasses could also project virtual soldiers and a battlefield for a three-dimensional gaming experience. The YouTube user ThereIsaCanal has created a video that's half spoof / half serious depicting what it would be like to play Battlefield 5 on Google glasses.
Unlike your traditional couch-surfing lackadaisical approach to online gaming, this kind of augmented reality gameplay would give you a guaranteed work out. Imagine crouching as enemy fire explodes across your glasses then choking a virtual soldier to death. Fun!
But seriously, we're probably a long way off from anything like this. First the game would have to analyze your surroundings and create challenges that fit into your environment. Still, this is a damn exciting sneak peak at what may be to come.
