A developer creates a shared reality by combining HTC Vive and HoloLens

A young developer synchronizes a simulation session in a HTC Vive headset with a HoloLens.


Drew Gottlieb, a young developer, has managed to combine virtual reality with augmented reality, through one of its applications. Inspired by the concept of Tilt Brush, the young man decided to connect a Vive headset with a HoloLens, Microsoft's helmet, to share the same session and collaborate to produce works with squares in 3D.


Gottlieb says on his blog: "Why do I have to get up off the couch to see what my friend is creating? Why can’t I just lean back and see the art floating in the middle of the room?"

So, based on the HoloLens development kit, two Vive controllers and an application running on both headsets, Gottlieb had a good starting base. But it is thanks to Unity's online services - a platform used to make video games - compatible with Vive, that the HoloLens was able to automatically connect to the simulation session of the VR helmet.

After that, the HoloLens user must use one of the two Vive controls to integrate his helmet to the simulation of the other. According to the developer, there are no limits on the number of users who can participate in the same "shared reality".

However, he acknowledges that there is more much work to do in order improve its application, especially with regard to controller tracing and the synchronization of the two realities. The developer says: "people can collaborate in within the same space, across virtual and holographic environments. As a spectator with a HoloLens, you can say to the VR player “I have an idea, hand me a controller” and then interact with the art yourself"

The source code of the "shared reality" developed by Gottlieb has been published on GitHub.
