Transitional space between real and augmented environment
Benchworks is a collaborative Augmented Reality application to facilitate in-situ and remote collaboration on urban design proposals. Two users can seamlessly integrate and observe virtual and real objects.
Implementation
BenchWorks combines optical tracking in form of the AR Toolkit and optional magnetic tracking. AR Toolkit provides an easy way to create input devices that do not rely on wires and therefore are more convenient in a multi-user setup. Magnetic tracking on the other hand provides higher precision for head orientation and in consequence provides more stable augmented vision. Thus, major benefits for this early prototype are combined: the precision of a magnetic tracking systems, the freedom of tangible interfaces and it overcomes the obstacle of occlusion within the scene. This has been changed later in the development to a huge multimarker setting. It is less stable (in terms of orientation measurement) but easier to integrate with existing hardware.
