Virtual reality and augmented reality (AR) are developing fastest in gaming and entertainment but potential uses can be found in nearly every sector from battlefield training for the troops to buying a home.

There are more than 1.2 billion gamers in the world, an easy market for the headset makers and software developers that can bring people into the game. On the other end of the VR spectrum, software creator MindMaze has created an immersive virtual-reality therapy that, according to the company, is helping patients regain motor and cognitive function faster than with traditional physical therapy.
