Not only will Windows 10 run on XBox, Microsoft is bringing Xbox Live to the desktop. Players will also be able to play Xbox One games on their PC by streaming them directly from their console to their Windows 10 tablet or PC within their home.
Microsoft is also working on an augmented reality system called HoloLens, using a headset a little like Google Glass. Windows 10 will be the first holographic computing platform and a set of APIs will mean developers can create holographic experiences in the real world. Apparently HoloLens lets you interact with 'holograms' that you see. You could use HoloLens to play games in a virtual 3D environment.
So Apple, what do you have to offer?
(a) There are patents that suggest that Apple has been researching some of these areas, read more here: What Apple patents say about iPhone 6, iPad 6, iWatch & other future products.
(b) How about this Virtual reality head mounted display patented by Apple
(c) There are also claims that Apple will integrate movement recognition into the Apple TV, and maybe also the Mac. This is based on the fact that the company acquired PrimeSense - the developer of the motion-tracking tech inside the original Kinect sensor for the Xbox 360...
(d) We'd really like to see Apple improve the Apple TV so that it runs all the games and apps available on the iPhone and iPad... Here's more about what we hope to see in the next Apple TV: Apple TV rumours.
