Information Visualization & Computer-supported cooperative work
Objectives By the end of class, you will be able to… • Define InfoVis and CSCW • Explain basic principles of good visualization design and ways in which visualization can be misleading • Explain some key issues that arise when designing for groups of users
It looks like a swirl. There are smaller swirls at the edges. It has different shades of red at the outside, and is mostly green at the inside. The smaller swirls have purple highlights. The green has also different shades. Each small swirl is composed of even smaller ones. The swirls go clockwise. Inside the object, there are also red highlights. Those have different shades of red also. The green shades vary in a fan, while the purple ones are more uni-color. The green shades get darker towards the outside of the fan......

Visualization is… Use of computer supported graphic representations of data to support human activities
Scientific Visualization: • Spatial layout is given by the data Information Visualization: • Spatial layout is chosen by the designer

What is CSCW? • Groupware: technology that people use to work together • “systems that support groups of people engaged in a common task (or goal) and that provide an interface to a shared environment.” • CSCW studies the design & use of groupware • “CSCW is the study of the tools and techniques of groupware as well as their psychological, social, and organizational effects.” Acknowledgement: Thanks to James Landay and Saul Greenberg for some cscw slides & images
Key Points • Visualization can valuable for data analysis and communication. • BUT, design visualization techniques carefully & avoid misleading the user. • Groupware can help people work together. • Designing for groups introduces many challenges not present for single users.
