Perceptual and interpretative properties of motion for information visualization
Lyn Bartram · 1997
Visualizing information in user interfaces to complex, large-scale systems is difficult due to an enormous amount of dynamic data distributed across multiple displays. While graphical representation techniques can reduce some of the cognitive overhead associated with comprehension, current interfaces suffer from the over-use of such representation techniques and exceed the human’s perceptual capacity to efficiently interpret them. New display dimensions are required to support the user in information visualization. Three major issues which are problematic in complex system UI design are identified: representing the nature of change, supporting the cognitive integration of data across disparate displays, and conveying the nature of relationships between data and/ or events. Advances in technology have made animation a viable alternative to static representations. Motion holds promise as a perceptually rich and efficient display dimension but little is known about its attributes for information display. This paper proposes that motion may prove useful in visualizing complex information because of its preattentive and interpretative perceptual properties. A review of animation in current user interface and visualization design and research indicates that, while there is strong intuition about the “usefulness ” of motion to communicate, there
