- 13. 13 Information VisualizationInformation Visualization Human eyes can interpret a graph much faster than plain texts, as it can process many visual cues simultaneously. The design look of the website is what visitors care much about compared to other website features such as information structure, information focus and usefulness of information. Visualization has been used in recommender systems in both offering recommendation to users and explaining why these recommendations were given.
- 14. 14 Visualization TechniquesVisualization Techniques To visualize information, a number of visualization techniques have been used such as tables, images, diagrams, text-highlighting, color schemes, rating and animation. More sophisticated methods include: Geometrically-transformed displays include techniques such as scatterplot matrices, projection pursuit techniques, prosection views, hyperslice and parallel coordinates Iconic displays include little faces, needle icons, star icons, stick figure icons, color icons and TileBars. Dense pixel displays include techniques such as recursive patterns and circle segments Stacked displays include dimensional stacking.

Decision Making Decision making is the selection of a course of action from two or more alternatives in order to solve a problem or to achieve an objective. It was found that the format of the information presented can affect what decisions consumers can make. The integration of recommendation technologies with a profound realization of human decision making can improve the quality of recommendation for users and the predictability of decision outcomes. There is strong a relationship between visualization of information and two other disciplines. Understanding this relationship is important for a better RS design:
- 20. B. Human Computer Interaction Human Computer Interaction (HCI) is concerned with how people interact with computers and how computers can be developed for successful interaction with human beings. The goal of HCI is to design systems that minimize the barrier between the human's cognitive model of what they want to accomplish and the computer's understanding of the user's task. By designing a good explanation interface, we can better explain recommendations and can even push users to make further requests. 20 Correlated DisciplinesCorrelated Disciplines
