Wishful thinking about the widespread adoption of
interfaces has not helped spawn winning applications.
Success stories with
three-dimensional games do not translate into broad
head-tracking immersive virtual reality. To accelerate
adoption of advanced
interfaces, designers must understand their appeal and
as well as honestly identify their deficits. We need to
separate out the
features that make 3D useful and understand how they help
challenges of dis-orientation during navigation and
occlusion. Does spatial memory improve with 3D layouts? Is
it true that 3D
is more natural and easier to learn? Careful empirical
studies clarify why
modest aspects of 3D, such as shading for buttons and
overlapping of windows
are helpful, but 3D bar charts and directory structures are
sometimes pays off for medical imagery, chemical molecules,
architecture, but has yet to prove beneficial for performance
shopping or operating systems. This talk offers a taxonomy
of 3D features
and applications, and advocates systematic empirical studies.
BEN SHNEIDERMAN is a Professor in the Department of Computer
Founding Director (1983-2000) of the Human-Computer
(www.cs.umd.edu/hcil/ ), and Member of the Institutes
Computer Studies & for Systems Research, all at the
University of Maryland
at College Park. He was elected as a Fellow of the
Computing (ACM) in 1997 and a Fellow of the American
Association for the
Advancement of Science
(AAAS) in 2001.
Ben is the author of Software Psychology: Human Factors in
Information Systems (1980) and Designing the User Interface:
Effective Human-Computer Interaction (3rd ed. 1998)
. He pioneered the highlighted textual link in 1983, and it
became part of
Hyperties, a precursor to the web. His move into information
helped spawn the successful company Spotfire
www.spotfire.com/ . He
is an advisor for www.smartmoney.com/ where his
visualization is used for stock market data, and for
www.Clockwise3D.com which has developed a 3D front
end for Windows.
With S. Card and J. Mackinlay, he co-authored Readings in
Visualization: Using Vision to Think (1999). Leonardo's
Laptop (MIT Press)
will appear in Summer 2002.
