Children's performances using three different mouse interfaces to control point-of-view (POV) navigation in a prototype of a CD-ROM based "virtual forest" were asse...
Treemaps support visualization of large hierarchical information spaces. The treemap generation algorithm is straightforward and application prototypes have only minimal hardware ...
An experiment was carried out to estimate the effect of sound feedback on the work of a plant operator. Eight students of computer science operated a process simulation program of...
