Want a virtual assistant that means you won't lose anything ever again? A patent application filed by Microsoft hints at that future. From a report on CNET: The technology described in the patent filing, published Thursday, would bring sophisticated, automatic object tracking to augmented reality. A cousin of VR, which creates an entirely digital experience, augmented (or mixed) reality blends the real and virtual worlds into a seamless experience -- think Pokemon Go. One of the challenges for more advanced augmented reality is that a system would need to track not only you as a user, but also the other objects in your environment. Microsoft's patent document suggests a technology that would do just that. The new tech would fit neatly with Microsoft's own HoloLens augmented reality platform. As AR becomes more common, it could lead to a future in which you can ask Cortana (or Siri or Alexa) where you left your shoes or if you're out of eggs.
