Google’s WorldSense

Lenovo just announced the Mirage Solo VR headset with Google’s WorldSense inside-out tracking capability. The result is an untethered VR headset which presumably has spatial mapping capabilities, allowing spatial maps to be saved and shared. If so, this would be a massive advance over ARKit and ARCore based AR which makes persistence and collaboration all but impossible (the post here goes into a lot of detail about the various issues related to persistence and collaboration with current technology). The lack of a tether also gives it an edge over Microsoft’s (so-called) Mixed Reality headsets.

Google’s previous Tango system (that’s a Lenovo Phab 2 Pro running it above) did have much more interesting capabilities than ARCore but has fallen by the wayside. In particular, Tango had an area learning capability that is missing from ARCore. I am very much hoping that something like this will exist in WorldSense so that virtual objects can be placed persistently in spaces and that spatial maps can be shared so that multiple headsets see exactly the same virtual objects in exactly the same place in the real space. Of course this isn’t all that helpful when used with a VR headset – but maybe someone will manage a pass-through or see-through mixed reality headset using WorldSense that will enable persistent spatial augmentation using a headset with hopefully reasonable cost for ubiquitous use. If it was also able to perform real time occlusion (where virtual objects can get occluded by real objects), that would be even better!

An interesting complement to this is the Lenovo Mirage stereo camera. This is capable of taking 180 degree videos and stills suitable for use with stereoscopic 3D displays, such as the Mirage headset. Suddenly occurred to me that this might be a way of hacking a  pass-through AR capability for Mirage before someone does it for real :-). This is kind of what Stereolabs are doing for existing VR headsets with their ZED mini except that this is a tethered solution. The nice thing would be to do this in an untethered way.
