Usher, the Augmented Reality user interface (fig 2) for Australia«s Telerobot on the Web, gives an example of how visual enhancements can compensate for most of the disadvantages of multiple monoscopic views.
The stick cursor is a simple and versatile tool to visualize and specify locations in three-dimensional environments with a known surface topology. It also allows visualization and manipulation of two rotational angles. The stick cursor does not only present data to the operator but it can be interactively manipulated with a mouse. DOF are represented by one element of the stick cursor each. Hence they can be controlled independently. Consequently, users can manipulate 5 DOF with a two-dimensional mouse graphically.
Applications of the new interface are not limited to telerobotics. Almost any task that includes manipulation of elements in real or virtual three-dimensional environments could integrate the stick cursor as an additional tool, e.g. path planning for indoor cranes and blimps, manipulation of camera or light positions for theater or TV productions, telemaintenance, CAD and animation software.
