Convergent GPS
Uncertainty in the wild can be deadly. Even with existing GPS technology, hundreds lost of hikers and campers cost the government and park districts millions. Convergent GPS is a tool to span the difference between knowing where you are on a map and knowing where you are in the world.
Photoshop / Illustrator Rendering
2D renderings are useful when making color, texture or placement decisions.
Procedural User Testing
The first two tests were often wildly inaccurate, however subjects quickly began to understand the concept of looking at a flattened version of the horizon and reached a consistent error rate (pages 1, 2). In general more points of data improved accuracy however in the second test (page 2) where many points of data were supplied; the accuracy was not substantially improved. The single most important tool for improving accuracy seems to be anything that shows the direction one is looking on the map, either through “book ending” (page 14) or showing the cone of vision as un-shaded on an otherwise shaded map (pages 6, 8, 4, 10).One possible conflict might prove to be a tendency toward landmarks. Even if the site to be found was nondescript, our subjects tended to assume that the point belonged to a feature on the horizon.
