.... However, while instrumented props [5] are useful for specific tasks, there is also a requirement for more general purpose techniques (and, in the case of VRML browsers, for using more widely available 3D devices) The solution proposed by Wloka and Greenfield, known as the Virtual Tricorder [19], uses the metaphor of a reconfigurable tool and again adopts a direct mapping between input device and its virtual representation. In this case the representation is a model of the actual ultrasonic 3D mouse used, with the addition of extras such as 2D anchored menus which pop up when required. ....

....the rotational offset, this virtual device mirrors the operation of a real world magnifying glass, except that by giving the user control of the field of view (via the Slider) the device also becomes zoomable. This technique replicates the functionality of the Virtual Tricorder s magic lens [19]. 6. INITIAL EVALUATION A small number of initial user trials were run to compare the North aligned and View aligned map tools. The scenario used for testing was a simple maze running task using a small maze comprised of cubes, cones and cylinders each of which could appear at two different ....
