Abstract :
We have developed a system built on our mobile AR platform that provides users with see-through vision, allowing visualization of occluded objects textured with real-time video information. We present a user study that evaluates the userpsilas ability to view this information and understand the appearance of an outdoor area occluded by a building while using a mobile AR computer. This understanding was compared against a second group of users who watched video footage of the same outdoor area on a regular computer monitor. The comparison found an increased accuracy in locating specific points from the scene for the outdoor AR participants. The outdoor participants also displayed more accurate results, and showed better speed improvement than the indoor group when viewing more than one video simultaneously.
