Fig. 5. This is an example of an initial virtual world positioning task trial in a “room
with walls” scene background with each object casting one shadow. The task was to
reposition the misplaced sphere so as to outline a larger, isometric cube figure. The
spheres in this example outline the vertices, or corners, of the larger, isometric cube
figure.
Fig. 6. This is an example of an initial virtual world positioning task trial over a
“stair-step” scene background with each object casting one shadow. The task was to
reposition the misplaced cube so as to outline a larger, isometric cube figure. Once
correctly placed, the cubes in this example outline the vertices, or corners, of a larger,
isometric cube figure.
