 |
User InteractionA set of blocks is used to demonstrate how the system can automatically compute the likelihood than one object is been selected. |
 |
Very Low Acuraccy TrackerA train set is transformed into a very low accuracy tracker as an example of a tracker that reports its accuraccy. |
 |
Transform CombinerTransform Combiners allow more than one tracker to be used for the same object. At run time the system decides how to combine the values reported by the various trackers. |
 |
Transform Combiner and BounderA Bounder illustrates the current error estimate, showing how the system chooses which tracker to use on the fly. |
 |
Pending TransformA Pending Transform is a transformation that does not have its value specified at design time. It will be automatically updated by the system at run time. |
 |
Error BounderThe Inner and Outer regions are automatically computed at run time. They correspond to regions that are respectively always inside and outside the object. |
 |
Adaptive LabelsLabels are shown on top of the drawers when they are deemed correct. In the case they may be misleading, the system places them on the top-left corner and displays call-out lines. |
 |
Registration ErrorThe misalignment between the computer generated graphics and the physical object it is supposed to augment may be misleading. |
