A new augemented reality headset was revealed by Microsoft during their Windows 10 event yesterday - the Microsoft HoloLens.
The HoloLens is a head-mounted computer which has its own built-in sensors and processors - there are no other gadgets or equipment needed in order to use it.
The headset's translucent lens allows the wearer to see graphical imagery within their current real-world environment.
Microsoft did an on-stage demo of the technology using an AR app called 'Holo Studio', which allows for the user to build 3D objects using hand gestures.
Have a look at the stage demo below.
Microsoft also have a concept video for the HoloLens which you can see below. Keep an eye out for the Minecraft part at the 0:59 mark.
The HoloLens tech is still being developed, but Microsoft said it is a big part of their future plans. HoloLens is set to launch at some point during the Windows 10 lifecycle, but the company gave no other timeframe.
