Virtualized Reality:
Digitizing a 3D Time-Varying Real Event As Is and in
Real Time
Takeo Kanade
The Robotics Institute
Carnegie Mellon University
I will present the CMU Virtualized Reality project. Digital imaging of
two-dimensional pictures is common today. Capturing an entire 3D scene
or even a time-varying event into a computer as a 3D form, however, is
very difficult and rarely done. Imagine a few players playing
basketball on a court. Can we digitize the whole scene into a computer
as a "3D event", not as a collection of pictures, but as its
three-dimensional, time-varying, and volumetric/surface
representation? If we could do so, we can use the representation for
various purposes. For example, we can think of a "soft" camera -
creating images from any arbitrary viewpoints and angles at which
there were not cameras originally. With a soft camera, one can see the
basketball game from any view point independent of physical
limitations or other viewers' interest: from inside of the court, from
the referee's point of view, or even from the ball's eye point of
view. Image rendering, however, is not the only application. We can
archive, manipulate, combine, and alter real events - a whole new
notion of "event archiving and manipulation" or "Virtualized Reality".
Since 1993, we have been developing Virtualized Reality technologies
with the 3D Room - a fully digital room that can capture events
occurring in it by many (at this moment 50) video cameras. I will
describe the theory, facility, computation, and results of the
project.

EE380: COMPUTER SYSTEMS COLLOQUIUM
on Wednesday, 17 November 1999, 4:15pm to 5:30pm
NEC Auditorium (B03), Gates Computer Science Building
http://www.stanford.edu/class/ee380/contents.html
From BSD to Jini:
Adventures in Technology, Openness, and Community
Bill Joy
Founder and Chief Scientist
Sun Microsystems
I created the BSD Unix distributions 20 years ago, and distributed the
source for these widely. The most notable technical contribution of
BSD was a high-performance and well-debugged implementation of TCP/IP
on the internet, because code was available in source form. Sun
started shortly thereafter, and pioneered the notion of "open system",
with public interfaces but proprietary implementations, a big advance
over the proprietary systems of the time.
Now, with Jini, we are both making the source code widely available,
but also promoting a new way of distributing protocols: namely by
shipping "agents" (objects which implement a protocol around), by
structuring distributed systems as object/agent based systems. This
technical approach allows us to skip several steps: we don't need to
write human-language protocol descriptions in order to distribute new
functionality and protocols. This promises to greatly increase the
rate of innovation in deployed services on the network.
This talk will discuss the reasons why the TCP/IP distribution was
successful, the motivation for sharing the source of Berkeley UNIX in
the way we did, and the similar reasons that we are optimistic about
Jini. It will also discuss the thinking behind the Sun Community
Source License, the Java Community Process, and the Jini Community,
and how these provide new opportunities for sharing and working
together effectively in the age of the net.
Biography: Bill Joy, 44, Chief Scientist of Sun Microsystems, Inc., is
a co-founder of the company and a member of the Executive Committee
Bill received a B.S.E.E. in Electrical Engineering and Computer
Science from the University of Michigan in 1975, after which he
attended graduate school at U.C. Berkeley where he was the principal
designer of Berkeley UNIX (BSD) and received a M.S. in Electrical
Engineering and Computer Science. The Berkeley version of UNIX became
the standard in education and research, garnering development support
from DARPA, and was notable for introducing virtual memory and
internetworking using TCP/IP to UNIX. BSD was widely distributed in
source form so the others could learn from it and improve it; this
style of software distribution has now led to the "open source"
movement, of which BSD is now recognized to be one of the earliest
examples.
For his work on Berkeley UNIX, Bill received the ACM Grace Murray
Hopper Award which is given for outstanding work in Computer Science
when the recipient is under the age of thirty. In 1993, Joy was given
the Lifetime Achievement Award of the USENIX Association, "For
profound intellectual achievement and unparalleled services to the
UNIX community."
Since joining Sun from Berkeley in 1982, he has led Sun's technical
strategy, spearheading its open systems philosophy. He designed Sun's
Network File System (NFS), and was a co-designer of the SPARC
microprocessor Architecture. In 1991 he did the basic pipeline design
of UltraSparc-I and its multimedia processing features. This basic
pipeline is the one used in all of Sun's SPARC microprocessors
shipping today.
More recently, Bill has led design investigations of architectures for
UltraSparc V, driven the initial business and technical strategy for
Java, co-designed the picoJava and ultraJava processor architectures,
co-authored the specification for the Java Programming Language, and
co-designed the lexial scoping and reflection APIs for Java version
1.1.
Bill's most recent work is on the Jini distributed computing
technology for networking computer devices using Java, and on the Sun
Community Source Licensing (SCSL) model, designed to allow companies
to share their intellectual property in source form, to facilitate
cooperation with customers, partners, educators and
researchers. Further information on the SCSL is available at
http://www.sun.com/jini [1].
In 1997, Joy was appointed by President Clinton as Co-Chairman of the
Presidential Information technology Advisory Committee. The Advisory
Committee is providing guidance and advice on all areas of high-
performance computing, communications and information technologies to
accelerate development and adoption of information technologies that
will be vital for American prosperity in the twenty-first century. The
report of the committee is available at
http://www.hpcc.gov/ac [2]. Bill was appointed as Chief Scientist of
Sun in 1998. His current research is into new uses of distributed
computing enabled using Java and Jini, new methods of human-computer
interaction, new microprocessor and system architectures, and the uses
in computing of scientific advances in areas such as complex adaptive
systems, quantum computing, and the cognitive sciences.
Bill is the co-recipient, with Andy Bechtolsheim also a co-founder of
Sun and now a VP at Cisco Systems, of the Computerworld Smithsonian
Award for Innovation in 1999. Bill is a member of the National Academy
of Engineering and a fellow of the American Academy of Arts and
Sciences. Bill has 13 issued patents, with 10 in progress.

California School Administrators Summer Walk in the PARC
R. Baker, Dr. G. Gross, Dr. S.L. Miller, K. Silberberg, B. Hardee,
Dr. R.L. Thomas and C. Wheaton
Association of California School Administrators
The centerpiece of the Alliance between ACSA (Association of
California School Administrators) and Xerox is the PARC Intern
Program. Beginning in the Spring of 1998, more than 60 applicants
applied to become an ACSA/Xerox intern during the
summer. Administrators across the state were invited to participate in
the process of spending 20 days interacting face to face with the
scientist at the PARC facility.
This unique Alliance marked a new direction for ACSA and it's
membership. Never before had ACSA teamed with a corporation that
could provide a glimpse into the technologies of tomorrow and employ
strategic planning techniques that would prepare California
administrators for the changes those technologies will ultimately
cause.
The "Walk In the PARC" forum will show how the discussions with PARC
researchers have influenced work practices of California School
Administrators. This forum will focus on ten specific practices that
the ACSA Interns have implemented back in their professional public
school life. These practices are both cultural and technical and have
there origin from discussions with PARC researchers.
Biography: Championing the proper use of technology in our schools
today, the seven ACSA Interns represent a variety of careers as
teachers, vice principals, principals, classified, district and county
administration. They hold advanced degrees and are faculty members at
several colleges and universities.
All interns have been frequently called on to consult, train and give
keynote presentations for school districts, businesses and
organizations within our state, county and even internationally. A
wide variety of local, national and international awards are held by
this intern group for their outstanding leadership in our K-12 school
systems.

Methods for Proving Relative Loss Bounds
Manfred K. Warmuth
Computer Science Department
University of California, Santa Cruz
mailto:manfred@cse.ucsc.edu
We consider on-line learning from examples. We start with a
parameterized model class and a loss function that assigns each
example and model a non-negative loss. The on-line algorithm sees one
example at a time and incurs a loss on the current example based on
its current model. This model (hypothesis) is updated on-line as more
examples are seen by the learner. The best fixed model is chosen
off-line. It is the model in the class with the smallest (total) loss
on all examples.
The loss of the on-line algorithm on a sequence of examples is
typically larger than the loss of the best off-line model. However,
the goal of the on-line learner is to minimize the additional loss of
the on-line algorithm over the loss of the best off-line model. Thus
the off-line model serves as a comparator. Bounds relating the on-line
loss to the best off-line loss are called relative loss bounds. Such
bounds quantify the price of hiding the future examples from the
learner. The bounds hold for arbitrary sequence of examples.
We will review methods for proving such bounds. We will emphasize a
method that starts with a divergence measuring the "distance" between
the parameterized models. This divergence function is used to derive
the parameter update of the on-line learner and it becomes the
potential function in the proof of the relative loss bound for the
same update. Finally we discuss the case when the off-line comparator
is allowed to "shift" over time. In some cases one can obtain bounds
on the additional loss of the on-line algorithm over the loss of the
best "shifting" off-line model.

Perspective Taking Amongst Distributed Workers
Pamela Hinds
Stanford Dept. of Industrial Engineering and Engineering Management
mailto:phinds@leland.stanford.edu
This talk with focus on the effect of geographic distance and unshared
context on shared mental models of work. Shared mental models are
considered a pre-condition to coordinated group action, but much of
the work on the development of shared mental models has assumed
co-location of team members. Prof. Hinds will discuss the results of
an experiment examining the development of shared mental models of
work in distributed versus co-located teams. She examines the role
that shared versus unshared context plays in the development of shared
mental models in distributed teams. In addition, she will present
some evidence that distributed teams may not receive the same benefit
from having shared mental models as do co-located teams.
Biography: Pamela Hinds is Assistant Professor of Industrial
Engineering and Engineering Management at Stanford. She studies the
interplay between information technologies, information sharing, and
human judgment, as a core faculty member of the Center for Work,
Technology, and Organization. She is currently conducting research on
the affect of remote and distributed work on employees' shared
understanding of work, the affect of intellectual property agreements
on information sharing, and the limitations of expertise.

A Datamodel and Algebra for XML
Ashok Malhotra
IBM Research
Before we can talk about a query language for XML we need a data model
and algebra. This talk will discuss some joint work we have been doing
with Oracle and Microsoft on a datamodel and algebra for XML. We will
discuss how this model is different from the Info set and also discuss
some considerations for a syntax. This paper has been submitted to the
W3C XML Query Working Group.
Biography: After receiving his Ph.D. from MIT, Ashok Malhotra has been
with IBM Research for almost 25 years. In the late seventies and early
eighties, he designed and built an Entity-Relationship database with
integrated language support. Later, he built the first visual database
query interface. More recently, he designed an object database for the
IBM AS/400 that took advantage of its long address architecture and
built-in persistence mechanisms.
Dr. Malhotra is the author of over 30 technical papers and holds 5
patents. He represents IBM on the XML Schema and XML Query Working
Groups.

STANFORD SEMANTICS WORKSHOP

http://www-linguistics.stanford.edu/semgroup/
Proper Names
Geoffrey Nunberg
When we say that an expression like 'Charles Dickens' or 'Italy' is a
proper name we usually have essentially semantic properties in mind.
First, and criterially, proper names are "used to designate a a
particular individual object," as the OED puts it. Second, the
relation between proper names and their bearers isn't mediated by a
linguistic meaning or Fregean sense -- in J. S. Mill's terms, "Proper
Names have strictly no meaning; they are mere marks for individual
objects."
Alongside of these narrowly semantic properties, though, proper names
have characteristic sociolinguistic properties. They may receive
special orthographic treatment, for example, and they are regarded as
not strictly "part of the language" when it comes to compiling
dictionaries and the like -- as James Murray put it, "Proper or merely
denotative names [are] outside the province of lexicography."
Linguists and philosophers who write about proper names tend to
concentrate on their semantic rather than their sociolinguistic
properties. But when we examine proper names from the sociolinguistic
point of view, they turn out not to conform to the semantic criteria
that people associate with the class. There are proper names that
clearly have Fregean senses, for example, such as 'Eldorado' and
'Northwest Passage' -- expressions that are intuitively distinct from
the extensionally equivalent descriptions that are used to define
them. Nor does it suffice to say that proper names are defined as
having unique denotations -- there is no purely extensional
characterization, for example, that will serve to distinguish a
(lexicographically) proper name like 'National Socialism' from a
common noun like 'communism'. What makes these expressions (and indeed
all proper names) "proper," I'll argue, is not the uniqueness of their
denotation as such but rather the fact that their relation to their
bearers is fixed relative to a unique and nongeneralizable historical
context. In this connection, finally, I'll turn to the case of the
names of "proper kinds," for example brand names like 'Chevrolet'.
While words like these are clearly morphosyntactic common nouns, I'll
suggest that lexicographers are right to distinguish them from words
like 'automobile' on semantic grounds.
