Two new videos posted to Twitter by iOS developer Andrew Hart show points of interest and navigation directions overlaid on what the device’s camera sees, illustrating one possible use for the company’s upcoming ARKit. In the first video, Hart moves his phone around from a London rooftop as the app points out points of interest in the skyline. In the second video, Hart types in “Starbucks” and is greeted by floating red arrows and a blue line displayed over the roads seen in his camera feed, leading him to his destination. The idea is similar to an Apple patent filed late last year for “Augmented Reality Maps” that layer map information and directions over live iPhone video, although the Apple model is displayed with the phone held horizontally and Hart said he’s only been able to get his working with the phone held vertically due to issues in ARKit. Hart said he plans to have his library up on GitHub this week.
