Taking Digital to the High Seas
CAMBRIDGE, MA—Sept. 30, 2019 — When GPS isn’t available to pinpoint location, wearable technologies that rely on this information can run into problems. That’s the case when augmented reality glasses can’t get a GPS signal—particularly when traveling long distances in unknown environments. Without location accuracy, information that’s supposed to be overlaid graphically on views of the real world do not appear aligned to the user.
Now, engineers at Draper have devised a way for an augmented reality (AR) system to work accurately without GPS over large areas of operation. The way in which they use a navigation system to maintain alignment between the real world and the digital world of augmented reality has earned its inventors a patent.
“Many current inertial navigation systems benefit from, or require, known points of reference or mapping technology to maintain the positional accuracy of AR elements,” said Eric Jones, a Principal Human Factors Engineer at Draper. “Our system is configured so that it can operate in unknown environments without needing to build a virtual map or use such a map to estimate location and orientation.”
Immersive reality—the practice of using augmented or virtual reality (VR) technologies to enhance an experience—is growing in adoption. Newspapers are trying it out in order to retain readers, and ...
