Ideas Seminar – Eric Sauda
Date: August 15, 2013
Professor Eric Sauda started off by providing a brief
introduction and a precise description about his research area. Initially, he talked
about issues related to urban visualization from the perspectives of urban
design and computer visualization. He stresses on the interactive visualization
which is a new form of communication, providing presentations that allow
viewers to interact with information in order to construct their own
understandings of it. I think most of people are not expert in research area. We
should try to communicate and make them understand. To do so, this project enables
the development of new computation technologies to view data and to use
interaction abilities and better communicate the results.
The project presents urban visualization in Charlotte. Actually,
there’s a lot of system to display large collection of data for urban study. However,
most of systems are focused on statistical chart, manual calculations to
understand relationships in urban environment. Furthermore, these systems often
limit the user’s perspectives on the data, limiting the user’s spatial
understanding and cognition of the viewing region. But he suggests 3D view of
the urban model, a separate but integrated information visualization view
displays multiple disparate dimensions of the urban data, allowing the user to
understand the urban environment both spatially and cognitively in one glance. Urban
visualization system contains features that interact with urban data, and enhances
their ability to better understand the urban model.
I thought the lecture was extremely interesting, not like
the traditional talks that are full of jargon but talk more about improving the
interactive visualization. As many researchers have pointed out, computing
today is moving away in a number of ways. In this sense, I can understand how
helpful this interactive urban visualization tool will be in developing and
providing intuitive understanding of the urban data and learning algorithms. For
the future work, he tries to enable a user to gain a sense of urban legibility
that will include both the geometric form as well as the flow of information
and goods. I guess, for doing this we need to continue to be a great deal of borrowing
of techniques and ideas from artificial intelligence and other areas of
computer science.
