The CSLI Calendar appears on Thursday of each week throughout the academic
year. Announcements, abstracts, and other information to appear in the
Calendar on a given Thursday should be submitted by e-mail to
incalendar@csli.stanford.edu by 5:00 p.m. on the previous Tuesday.
Past issues of the CSLI Calendar, a quarterly schedule of upcoming CSLI
events, and other information about CSLI are available on the World Wide Web:
<http://csli-www.stanford.edu/>. The Calendar, with available abstracts, is
also posted each week to the csli.bboard newsgroup.

STASS SEMINAR
on Thursday, 6 October
10:00 a.m., Cordura Hall, Room 100
An Introduction to Situation Theory
Keith Devlin
Saint Mary's College Mathematics
<devlin@stmarys-ca.edu>
This is the first in a series of about six introductory lectures on situation
theory, concentrating on applications rather than the underlying mathematics.
At first, the lectures will cover material included in my book _Logic and
Information_ (Cambridge University Press, 1991), so people will be able to
join the course after it gets underway. However, the order of presentation
will not be exactly as in the book, and I plan to provide alternative
motivations and insights gained since the book was published. Later lectures
will cover material not in the book.
Motivational applications will include situation semantics, the analysis of
problems in sociolinguistics, and the design of information systems.

SEMINAR ON HUMAN-COMPUTER INTERACTION
on Friday, 30 September
12:30 p.m., McCullough Building, Room 134
Spreadsheets for Images
Marc Levoy
Stanford Computer Science
<levoy@cs.stanford.edu>
The majority of commercially available image processing and data visualization
systems employ a dataflow paradigm. Users select modules from a menu and wire
them together using an interactive flow chart editor.
I will describe an alternative paradigm based on spreadsheets. Cells in such
a spreadsheet contain graphical objects such as images, volumes, or movies.
Cells may also contain graphical widgets such as buttons, sliders, or movie
viewers. Objects are displayed in miniature inside each cell. Formulas for
cells are written in a programming language that includes operators for array
manipulation, image processing, and rendering. Formulas may also contain
control structures, procedure calls, and assignment operators with side
effects.
Compared to flow chart visualization systems, spreadsheets are more
expressive, more scalable, and easier to program. Compared to numerical
spreadsheets, spreadsheets for images pose several unique design problems:
larger formulas, longer computation times, and more complicated intercell
dependencies. We describe an implementation based on the Tcl programming
language and the Tk widget set, and we discuss our solutions to these design
problems. We also point out some unexpected uses for our spreadsheets: as a
visual database browser, as a graphical user interface builder, as a smart
clipboard for the desktop, and as a presentation tool.
MARC LEVOY is an assistant professor of Computer Science and Electrical
Engineering at Stanford University. He received a B. Architecture in 1976
from Cornell University, an M.S. in 1978 from Cornell University, and a Ph.D.
in Computer Science in 1989 from the University of North Carolina at Chapel
Hill. He was principal developer of the Hanna-Barbera Computer Animation
System and served as its director from 1980 through 1983. He has published
over thirty papers on computer animation, volume visualization, and medical
imaging. His current research interests include visualization of
multidimensional sampled data, digitization of 3D objects using active sensing
technologies, and the design of languages and user interfaces for data
visualization. Professor Levoy received the NSF Presidential Young
Investigator Award in 1991.

SYMBOLIC SYSTEMS FORUM
on Thursday, 6 October
4:15 p.m., Building 60, Room 61-F
Computers are Social Actors: A New Paradigm
and Some Surprising Results
Clifford Nass
Stanford Communication
<nass@leland.stanford.edu>
In this presentation, we discuss the results of a multi-year research program
of experimental studies that demonstrate the ways in which users respond
socially to interfaces and computer-based agents. We demonstrate that users
use social rules and invoke social schema to interpret and respond to the
behavior of computers and agents. Hence, human-technology interactions are
fundamentally social. The studies all are based on the idea that one can
apply theories and methods from the social sciences directly to users'
interactions with computers.
Studies to be discussed include:
(1) Are computer personalities like human personalities?
(2) Do users apply politeness rules to agents?
(3) Do users apply notions of "self" and "others" to agents?
(4) How do users differentiate agents?
(5) What does it mean when a computer says "I"?
(6) How does the gender of agents affect users' perceptions?
(7) Can computers be "teammates"?
(8) How does the labelling of technologies as "specialists" affect user
perceptions?
For each study, I will discuss theory, method, results, and theoretical and
design implications for the implementation of interfaces and agents.
(N.B. -- If you heard Nass's talk at CSLI last year, approximately 20% of the
material is new. If you heard Nass's talk at the PCD seminar two years ago,
approximately 90% of the material is new).
CLIFFORD NASS is an associate professor of Communication at Stanford
University, with appointments in Symbolic Systems, Sociology, and Science,
Technology, and Society. He received his B.A. cum laude in Mathematics and his
Ph.D. in Sociology, both from Princeton University. He has worked as a
computer scientist for the IBM Research Center in Yorktown Heights and Intel
Corp. He has been a principal investigator on grants sponsored by US West
Advanced Technologies, National Science Foundation, the Center for Integrated
Facilities Engineering, and Stanford University. He has consulted for
American Electronics Association, Amoco, Apple, IBM, Microsoft, and the
Smithsonian Institute. He has published a couple dozen journal articles and
book chapters concerning technology and statistical methodology.
