Apple is partnering with an AR startup called Dent Reality, specifically to work on indoor mapping and navigation based on AR (via AppleInsider).
Dent Reality
Apple’s Indoor Maps Program helps businesses create maps of their buildings on the inside so people can navigate using Apple Maps. These maps are based on the Indoor Mapping Data Format. Currently, Dent Reality is the only company working with Apple’s program, providing indoor AR navigation tools that Apple can then offer to other businesses.
Dent Reality’s tweet says that its “setting up projects for later this year.”
