Microsoft unveiled the latest version of its HoloLens augmented reality headset on Sunday, promising wearers would feel more immersed in the augmented reality experience and more comfortable. Slipping on the carbon fibre goggles is as "simple as putting on your favourite hat", Microsoft developer Alex Kipman told a launch event at the mobile industry's biggest trade fair in Barcelona.
