* A GIScience Perspective on the Human-Computer Interface *

The talk will discuss geographic information science perspectives on the human
computer interface and will provide an overview of research projects at the
Human Factors in GIScience Lab at the GeoVISTA Center at Penn State. The first
part of the talk will detail a research framework on cognitively assessing
qualitative spatial calculi for modeling human conceptualizations of geographic
scale movement patterns. The question addressed is the relationship between
formal calculi, cognitive conceptualizations, and different externalization
modalities. Besides first results, visual analytics software will be
demonstrated that allows for efficiently analyzing behavioral data. Further
topics will be (a) how Tobler's First Law (TFL) of Geography, that everything is
related to everything else but that near things are more related than distant
things, is perceived by human map readers and how their map interpretation
corresponds to formal measurements of TFL such as spatial autocorrelation; (b)
how salient shape characteristics influence the interpretation of map symbols
and how these effects can be leveraged; (c) how a combination of methods from
computational linguistics, georeferencing, and visual analytics, allows for
working with large, spatially stratified samples to answer questions such as
regional linguistic preferences.
