9/21/2012 – DEV Seminar Series talk – Representing data for human observers: Nuggets of wisdom from research in vision and cognition

Representing data for human observers: Nuggets of wisdom from research in vision and cognition https://sites.google.com/site/bernicerogowitz/vita Abstract: In visualization, we map data values and relationships onto visual dimensions to create a visual representation. But how well does that visualization represent the features and structures in the data? How well does it highlight aspects of the data that will help the analyst make good decisions? With all the visualization methods out there, is there one that is right? Using examples from financial risk analysis, cardiac modeling, and data mining, I will demonstrate how the application of insights from the study of color perception, perceptual scaling and attention can help guide your visualization choices. I will also emphasize the importance of matching the visual representation to analyst’s task, and show how the dynamic linking of multiple representations can be used to discover features in complex high-dimensional data. *To: (a) join DEV for free lunch during the talk; (b) schedule a one-on-one meeting with Dr. Rogowitz; or (c) join a small group for dinner on Friday with Dr. Rogowitz, please sign up on the DEV CTools site under the Sign-Up tab (respond to this email to be added to the site).  *Please note that lunch will be ordered only for those signed up via CTools by tomorrow, Wednesday, September 19. The DEV Seminar Series provides a platform for an interdisciplinary community of faculty, post-doctoral fellows, and graduate students to explore effective data visualization approaches for communicating with scientists from a range of fields and with non-scientists. Designed as a series of alternating invited talks and informal, student-led workshops, the aim is to bring together experts and practitioners with researchers who are facing the challenge of conveying complex information to different audiences through visualization, with the intention of stimulating explorations and conversations that enable knowledge to be shared and built upon.
