Towards perception driven visualization

The use of computer graphics techniques in visualization is hampered by the complexity of data, display limitations and the difficult process of establishing adequate mappings. One way to compensate for the difficulties in handling data and image complexity is to turn to users´ capabilities and human factors, and to revisit visualization and interaction techniques under such premises. This paper discusses aspects in the development of a multi-modal visualization system that considers human perception issues in the design of proper data displays. Perceptually driven techniques were implemented as modular extensions to a general-purpose, low cost and open visualization library. Some results are shown and implications discussed
