Apple’s AR technology could stop you getting lost in the mall
...a newly discovered patent reveals technology that would use AR for navigation purposes without requiring a GPS or cellular connection to work.
Called Visual-based inertial navigation, the patent lets a device position itself in a 3D space after interpreting data from the camera and sensors including the gyroscope, accelerometer, and others.
Using images and taking several measurements, the device can determine its orientation and position in real time. A GPS or cell connection isn’t required to calculate a highly accurate location, down to centimeters. Interestingly, the patent does mention that “smart glasses” are the kind of products that could benefit from such technology alongside smartphones and tablets.
Apple’s invention uses a technology called sliding window inverse filter (SWF) to minimize the computational overhead needed to combine data from multiple images and calculate a location.
