UWP seems to be a significant way forward now Microsoft has revealed that all tech will use the UWP. Also, having access to building for the UWP would allow a massive reduction on labour and development time if we can create for Windows, XBox One, and Windows 10 Mobile all at once with just really minor adjustments.
Other companies are starting to work on -type technologies (some without the glasses) - although it is still more at patent stage than anything concrete. Something tells me that Microsoft’s UWP compatibility is going to be very much at the forefront of the usable apps in these areas given their years of work ahead of the others in this field.
Microsoft are already recommending Unity as the development platform of choice for , and it would really behoove Epic to consider the potential past the first versions of and ahead into the next few years. As VR headsets become more advanced and start to use ‘see-through-the-headset’ tech, as well as reduce in size and weight, they’ll become more AR capable as well, and between all the large companies interested in developing such technologies, it would seem better to have large amounts of capable and practiced developers all well practiced and versed in making products for such technologies.
