Challenges Of Visualization

Current challenges of visualization of information
We want to summarize future possible directions for researches in visualization of information. It will help to provide the ground for understanding the current situation of the visualization of information and it will help people who want to take the challenge of finding new effective solutions for unsolved problems.
Scientific approach for visualization of information was launched in 1987 year (Johnson, 2004). The first author provided the list of top problems in this field was Bill Hibbard (1999): he indicated several groups of problems, such as visual quality, integration, information, interactions, and abstractions.
1. Visual quality: resolution of displaying should take into account

Scalable, distributed, and grid-based visualization. We may find new facilities on the foundation of grid based computing systems. Nowadays we require the modernization of resource usage of the distributed visualization for creating scalable algorithms.
14. Visual abstractions. Visual abstractions are still one of unsolved problems for visualization for user interaction process.
15. The theory of visualization. We should put our efforts on the development of the theory of visualization and researching the fields of fundamental problems. From computer graphics side it can be the physics of light transport and the processes of human perception. The angles that we can take as a starting point for our researches can be only underlying data or also human feedback for representation. Still a lot of improvements can be done in the field of handling complex and dynamic geometry.
Two previous authors that we have been analyzed were focusing on the problems of scientific visualizing – such approach, when the field mainly handling with nonnumeric, complex, and high-dimensional data. The next author - Chaomei Chen - focuses more on the general approach of visualizing the information and defines it as the “visual representations of the semantics, or meaning, of information” (Chen, 2005). There are the main challengies according to this author (Chen,

Usability. The studies about usability nowadays lag behind the fast space of development of visualization of information. Firstly, the analytical processes involved in creating the visual representations of raw data are still cannot be seen by users. These processes should be more obvious for users to be able to understand decision-making processes. Secondly, the interactive processes with visualized content are still not efficiently developed. That is why new evaluating methods are required to evaluate the visualization towards these problems. As usability concerns are tightly bounded with the understanding of perceptual processes of users, the second issue goes very close to this
