Interactive Representations of Information and Knowledge About the Module  This is 10 session module (two sessions are online)  This module deals with Interactive and Visual Displays of Information and Knowledge. We call these “representations”  You will learn to conceptualize and develop Interactive Visual Representations  This document presents outline of the module

Interactive Representations of Information and Knowledge Visualization  Visuals can communicate complex ideas with clarity, precision, efficiency and convey the most knowledge in the shortest time in the small space. ~ Tufte (1983)

Interactive Representations of Information and Knowledge Why Visual Content?  Contemporary technology allow easy creation of powerful visual displays  We can present a lot of information in a small screen space, communicate complex ideas through visual simplicity…  …and allow information consumer to manipulate and explore it in search for understanding  Interactivity significantly expense these possibilities

Interactive Representations of Information and Knowledge Visuals  Visuals might include maps, diagrams, drawings, images, icons, symbols, signs, flowcharts, etc  Computer-based visuals might be 2 dimensional and 3 dimensional  Color adds another dimension to visual communication

Interactive Representations of Information and Knowledge Minard’s Map

Interactive Representations of Information and Knowledge Minard’s Map (Tufte, 1983)  Forces visual comparisons (the upper lighter band showing the large army going to Moscow vs. the narrow dark band showing the small army returning)  Shows causality (the temperature chart at the bottom)  Captures multivariate complexity (size of army, location, direction, temperature, and time)  Integrates text and graphic into a coherent whole  Illustrate high quality content (complete and accurate data, presented to support Minard's argument against war)  Place comparisons adjacent to each other, not sequentially (people forget if they have to go from page to page )  Use the smallest effective differences (i.e., avoid bold colors, heavy lines, distracting labels and scales)

Interactive Representations of Information and Knowledge Interactivity  Contemporary technology brings visualization to much higher level by enabling interactivity  In addition, through technology it is possible to create dynamic and animated displays and to add audio to visual displays.
