Want geoscientists to be able to visualize data in context with their environment SHP data S AN D IEGO S UPERCOMPUTER C ENTER University of California, San Diego Early AR Development Start simple, find a practical application for geoscientists Using any existing map, overlay SHP data to provide additional context Demo soon! S AN D IEGO S UPERCOMPUTER C ENTER University of California, San Diego Whats Next? Outdoor environments are extremely diverse such as deserts and forests Tracking in such environments is very difficult Thus, for AR to work, new techniques are needed (such as computer vision) S AN D IEGO S UPERCOMPUTER C ENTER University of California, San Diego Using AR out in the field? PDAs, cell phones, or computer backpacks could be the main way to utilize AR PDAs and cell phones could be you window into the virtual world S AN D IEGO S UPERCOMPUTER C ENTER University of California, San Diego Final Goals Helicopter View Ground View S AN D IEGO S UPERCOMPUTER C ENTER University of California, San Diego Demo time!
