A new trademark filing suggests Microsoft is working on a new DirectX API for virtual reality and augmented reality applications. Not a lot of details are known but it's not hard to guess what "DirectReality" could be:
Those key categories, though, combine with the DirectX naming format to reveal the company's likely direction: a new DirectX API designed to help developers produce virtual, augmented, and holographic reality software and hardware, likely centred around the company's previously announced Windows Mixed Reality platform. If so, DirectReality is likely to arrive in an update ahead of the launch of third-party mixed reality headsets, due this summer.
Microsoft has not publicly commented on the trademark filing nor any plans it may or may not have to assist developers with AR, VR, and HR projects by launching a new universal API.
