ACM Honors Randy Wang and Digital Study Hall Team for
Using Community-Generated Video to Improve Education in India
AScribe Newswire (06/10/08)
Randy Wang and the Digital Study Hall (DSH) team have won ACM's Eugene L.
Lawler Award for Humanitarian Contributions within Computer Science and
Informatics. Wang and Urvashi Sahni of the Study Hall Foundation founded
DSH in 2005, and the project has developed a user-generated video-sharing
system that local teachers in South Asia use to improve learning in their
classrooms. The cost-effective digital technology allows schools and
non-governmental organizations to make videos of the best teachers and to
share them with teachers in underserved areas. Wang, currently with
Microsoft Research India, describes DSH as "a bit like YouTube meets
Netflix in a rural schoolhouse with a dirt floor." DSH currently has 30
pilot schools in five cities in India and Bangladesh. ACM will honor Wang
and the DSH team at its annual ACM Awards Banquet on June 21 in San
Francisco.

Tapping Computer Science for a More ACCURATE Vote
National Science Foundation (06/09/08) Cruikshank, Dana W.
A Center for Correct, Usable, Reliable, Auditable, and Transparent
Elections (ACCURATE), created in 2005 with a $7.5 million grant from the
National Science Foundation (NSF), is part of NSF's Computer and
Information Science and Engineering directorate's CyberTrust program.
ACCURATE project head and Johns Hopkins University professor Avi Rubin is
an expert in information security who was drawn to ACCURATE by the
challenges associated with improving voting technologies. He says that
once the researchers started examining the issue from a scientific
perspective, they discovered that a more holistic approach was needed to
understand how computers, touch screens, and other technologies work
together in elections. To accomplish this, ACCURATE unites experts from
various academic fields to find areas that need additional research and to
determine how to apply existing technology and research insights to voting
systems. One tool that resulted from ACCURATE is AttackDog, which can
examine more than 9,000 different ways a voting system can be attacked.
The program contains assumptions about each kind of potential attack and
countermeasure to create an attack tree. As new potential attack methods
become apparent, AttackDog can be updated to consider new threats.
Stanford University professor David Dill, who developed AttackDog, says the
program is an example of how ACCURATE uses computer science tools and
techniques to help local officials improve the security of their
elections.

Pioneers Steer the Course of Cyberspace
USA Today (06/11/08) P. 3B; Swartz, Jon
The Berkman Center for Internet & Society recruits technology executives
and academics to debate, argue, and possibly answer some of the most
difficult questions surrounding the Internet. The conclusions reached at
the Berkman Center could have a far-reaching effect on public policy in the
United States and abroad. "We wanted to establish a beachhead for the open
principles of the Net at Harvard and extend them to the university and
developing world," says Berkman Center co-founder and Harvard Law professor
Charles Nesson. Berkman executive director John Palfrey says the digital
revolution's biggest challenge is not new business models or Google's
search algorithms, but the massive generation gap between those who were
"born digital" and those who were not. Since 1998, the Berkman Center has
assembled an impressive lineup of contributing inventors, legal scholars,
and entrepreneurs who recognized the technical and legal inadequacies of
the developing Internet society. The center has helped create copyright
laws for the digital age, and formed the Internet Safety Task Force with
MySpace and 49 state attorneys general to identify technologies to protect
children from online predators. The center has also helped shape the Net
neutrality debate. "We don't always solve the problems, but often organize
and facilitate the hard conversations that lead to solutions," says Berkman
managing director Colin Maclay.

Dartmouth Launches Network Security Study
Dartmouth News (06/10/08) Knapp, Susan
Dartmouth researchers are about to launch the Dartmouth Internet Security
Testbed (DIST), a project that will study the school's wireless computer
traffic to understand how it's being used and how to protect it. Dartmouth
computer science professor and DIST principal investigator David Kotz says
the campus environment enables the researchers to examine live network
activity at scale and in real time. DIST will develop and evaluate current
sensing methods to monitor Dartmouth's multiple wireless networks. Kotz
says DIST's scope and scale are unique within the academic research
community, and that the project will improve network security technology
and practices for all Internet users. For example, DIST could help detect
unauthorized access points, which can be used to steal users' passwords.
The study has been designed to protect the privacy of all campus network
users. The researchers will not examine any of the content of wireless
network traffic, and instead will view only the header information. The
headers indicate the size and origin of the data, but not the type of data
or anything about the contents of the communication. The identity of
individual wireless devices will be replaced with random identifiers.

NIST Envisions 'Thinking Machine'
Government Computer News (06/06/08) Hickey, Kathleen
Programmers will be able to build thinking machines capable of reasoning
about complex problems using a technology system that will be developed by
ontologists, who are experts in the meaning of words and how to use them
appropriately to build actionable machine commands. Ontologists will
create an open ontology repository for holding a wide range of
dictionaries, compendiums of medical terminology, and product
classifications. Electronic and scalable, the open ontology repository
will allow users to distinguish, compute, reuse, and share data, documents,
and services. Information would include conceptual domains and specific
disciplines of communities; technical schema such as Resource Description
Framework, the Web Ontology Language and the Common Logic Framework; and
standard Internet languages such as Extensible Markup Language. "It will
save enormous amounts of time and money and facilitate new, complex systems
in all sectors for manufacturing control, supply chain management, and even
biomedical management systems," says the National Institute of Standards
and Technology's Steve Ray.

GPS Gadgets Can Reveal More Than Your Location
New Scientist (06/03/08) Graham, Flora
Microsoft researchers are working to enable GPS devices to know what you
are doing, including specifics such as which mode of transportation you are
taking. The researchers say such features could help people analyze and
improve their own lifestyles and share useful data with others. A
Microsoft team in Beijing, China, has developed a technique to
automatically guess a person's mode of transportation using GPS data. The
researchers recorded traces from 45 people carrying GPS-enabled gadgets
over six months, along with the volunteers' modes of transportation for
more than 20,000 kilometers. Analysis found that knowing someone's speed
is not enough to predict how they are traveling as factors such as traffic
congestion can alter the data. To avoid such problems, the researchers
developed statistical methods to improve the accuracy of predictions. The
travel prediction system was developed as part of Microsoft's experimental
Geolife Web platform for GPS, which aims to allow users to replay past
trips, view photos by location, and mine information such as personal
traffic congestion hotspots. The researchers say that publicly sharing GPS
data could allow people to choose travel routes and destinations based on
traffic conditions, although they acknowledge such information exchanges
have security implications.

Hands on Learning for the Visually Impaired
ICT Results (06/06/08)
The European Union-funded MICOLE project is working to make it easier for
software developers to build educational tools that will enable students to
see, hear, and feel what appears on the computer screen. Project
researchers have developed a program that allows both sighted and visually
impaired students to learn using the same system. Designed to teach
students about the solar system, visually impaired children use a special
device similar to a robotic arm to move around the solar system and hear
about the planets. Sighted children can guide their visually impaired
partners by moving their computer mouse, which increases pressure and
resistance in the robot arm to gently nudge the visually impaired user in
the right direction. The program is the first of a series being developed
by the MICOLE project as part of its multi-modal series. The researchers
say that haptic devices, such as the robot arm, could be used to control
computers like a mouse does by providing feedback to users through
movement, pressure, or raised bumps. Another MICOLE application allows
users to draw pictures and use the haptic device to feel the picture.
"Adding the sense of touch to information and communication technology is
just getting to the point where it can be commercialized," says project
coordinator Roope Raisamo. "The more senses you can use, the more
multi-modal your computer interface, the more inclusive the technology can
be."

New Zealand Gov't Looks to Boost Confidence in
E-voting
Computerworld New Zealand (06/06/08) Bell, Stephen
New Zealand is considering allowing voters to cast electronic ballots up
to 17 days before the general voting period and to re-vote if they have
concerns over whether their selections were recorded correctly. The
country's Chief Electoral Office has released the draft strategy document
in an effort to boost confidence in the electronic voting system. New
Zealand could conduct limited pilots for advance voting and re-voting
electronically during the 2011 or 2014 elections, and the earliest general
e-voting is likely to be offered is 2017. Still, "there will need to be a
period of extensive public consultation, and policy and legal work in
support of new legislation," says the Electoral Office in the strategy
document. New Zealand could approach authentication through the government
log-on service, which is being used for other government transactions. The
strategy document says the potential for malfunctioning machines, a mass
denial-of-service attack, and undue influence warrant taking a cautious
approach.

Moving Mountains With the Brain, Not a Joystick
New York Times (06/08/08) P. BU3; Eisenberg, Anne
Emotiv Systems makes a wireless headset system that allows players to
mentally manipulate objects in games through its ability to read and
process electrical activity from the brain, facial muscles, and other areas
when the user concentrates. The noninvasive EPOC headset is equipped with
16 sensors, and employs electroencephalography (EEG) to sense electrical
signals from the scalp's surface and translate them into actions that
control or augment game play. Emotiv research and development manager
Geoffrey Mackellar says the system uses constant feedback to learn more
about how users think concurrent with users' growing skills at
concentration. He notes that the headset is outfitted with a chip that
collects the signals and transmits them wirelessly to a receiver plugged
into a USB port of the computer, where most of the processing is executed.
University of Maryland professor Nathan Fox says the EPOC device is a
version of the EEG cap long used to record brain activity, and
medical-grade EEG caps are employed in research to monitor the brain as it
plans movement and to convert these plans into onscreen cursor actions so
paralysis victims can control a computer, for example. University of
Twente computer science professor Anton Nijholt is doubtful that all
consumers will be able to master the object manipulation skills that EEG
headsets can facilitate. Meanwhile, the OCZ Technology Group has just
released a headset called the Neural Impulse Actuator, which reads
electrical activity chiefly from muscles and translates it into commands
using a headband with three sensors, says OCZ's Michael Schuette.

Women Look to Excel in IT
Calgary Herald (06/07/08) Sankey, Derek
Organizations such as Women in IT, founded at Ryerson University in
Toronto by computer science student Nadia Harris, are providing role models
for women looking to enter the IT industry. Women in IT invites prominent
women in IT to speak at the school, which Harris says could help encourage
more women to enter the computing field. Meanwhile, Telus Corp. recently
launched an internal women's network, which the company's Andrea Goertz
says has opened up lines of communication, and the company is now aligning
with other companies' women's networks to share best practices and bring
more attention to the issue. TD Bank Financial Group CIO Heather Ross says
the industry needs architects and businesses analysts and people who can
translate the value of technology into various business areas, creating a
broader constituency of candidates to work in a technology field. Ross is
part of the Judy Project, a national network of women in senior executive
IT positions who share best practices, discuss challenges unique to women
in the field, and perform outreach functions to encourage women to enter
the field. Many higher-education institutions are also taking action.
The University of Calgary, SAIT Polytechnic, and Mount Royal College
recently united to promote high-tech careers for women by showcasing each
institution's variety of career opportunities to 9th grade girls. "There's
a war for talent on, so we need to focus on creating environments that
attract women at all levels," Ross says.

A Futuristic Linkage of Animals and Electronics
United States Department of Agriculture (06/06/08) Comis, Don
The U.S. Agriculture Department's Agricultural Research Service (ARS) is
testing the use of global positioning system (GPS) technology to track herd
animals. ARS animal scientist Dean M. Anderson has incorporated GPS
technology into a Walkman-like headset that allows the user to issue
commands to the animals to control their movements across a landscape, and
even remotely herd a group of cows into a corral. Anderson has been
working with MIT engineers to equip an Ear-A-Round device with high-tech
electronics. The prototype is a doughnut-shaped stereo that is worn over
each ear. Prior to working with MIT, Anderson patented technology for
virtual fencing called Directional Virtual Fencing (DVF), which focused on
giving cows "left" and "right" sensory signals to direct their movement.
Researchers at MIT's Computer Science and Artificial Intelligence
Laboratory have developed a miniaturized, solar-powered electronics package
for DVF devices that is packaged as a headset device. The commands given
to the cows through the headset vary from a familiar "gathering song" sung
by cowboys during manual round-ups, to irritating sounds such as sirens, to
mild electric stimulation if necessary to get cows to move or to avoid
going beyond boundaries.

Keys to Change
Melbourne Age (06/05/08) Molloy, Fran
The keyboard remains the most commonly used interface between people and
computers, although touch, handwriting, and voice-recognition technologies
are gaining momentum. Wacom's David Spencer acknowledges that keyboards
are in no danger of being supplanted by graphics tablets, but he notes that
the inputting of text comprises a mere fraction of computer use, while
touch-screen interfaces are especially important in situations where
convenience and mobility are critical. "In the classroom, for example, our
tablet technology is a great adjunct to interactive whiteboards and other
teaching tools where a keyboard is quite frankly redundant," Spencer says.
"Where you are trying to get information across, where you're trying to get
feedback, where you're trying to get interaction, the keyboard is a clumsy
knot in the middle." Professor Roope Raisamo of Finland's University of
Tampere says handwriting-recognition technology cannot match or outclass
the keyboard in terms of speed, while Sue Bennett of the University of
Wollongong says keyboard skills are an area of training that most schools
lack. Keyboards can also serve as a barrier for learning disabled people,
and voice-recognition technology can in certain instances free them up.
Tasmanian English teacher Margaret Neilsen discovered that
voice-recognition technology software enables her disabled students to
write their thoughts and then edit them into a structure.
Voice-recognition programs are also proving useful for professionals such
as Adrian Kelly, who produces transcripts of conferences and meetings in
real time by using voice-recognition software and a computer-aided
transcription program.

'Net Engineer Argues Firewalls Are a Security
Distraction
Computerworld Australia (05/30/08) Bell, Stephen
The focus on firewalls has led corporate network experts to spend less
time on security in the end system, says Brian Carpenter, the former head
of the Internet Engineering Task Force. Carpenter, currently a lecturer at
the University of Auckland, discussed the history of the Internet as well
as its challenges while giving the Institution of Engineering and
Technology's annual Prestige lecture. During his "The Internet, where did
it come from and where is it going?" address, Carpenter suggested that
firewalls have lessened the momentum of end-to-end transparency for the
Internet. He said the extended addressing scheme, IPv6, will replace the
need for address translation, but Internet users are so used to
conventional firewalls. There are some similarities between his view of
end-to-end transfer of data and David Isenberg's concept of a "stupid"
network, but he adds that the edge of today's complex networks might be
difficult to define, which has also been suggested by Victoria University's
John Hine. "The basic principle is still valid," Carpenter said. "It's
not obvious that you will make money out of putting very complex services
very deep in the network."

Video Searching Uses People Power
BBC News (06/03/08) Thompson, Bill
The British Parliamentary Web site TheyWorkForYou.com includes clips of
debates in the House of Commons, but the feed provided to the site only has
BBC-provided captions to indicate who is speaking or what the debate is
about. The captions allow the site to clip the video into segments, but
there is no way of automating the process or linking the clips to
particular speeches, which would enable site users to search through the
clips based on their subjects. Instead of developing an artificial
intelligence application capable of analyzing the clips, the site is asking
Internet users to watch short video clips of Commons speeches and match
them to the transcripts made for Hansard, the official record of
parliamentary proceedings. Similar to how the SETI@Home project uses spare
processing cycles on ordinary PCs to analyze radio astronomy data, the
MySociety project will use people's spare time to help categorize the video
clips. Users receive an extract from the speech and a piece of embedded
video. The user presses "play" and when they hear the exact start of a
phrase they press a "now" button to pinpoint where in the video stream that
text is said. The MySociety tool is currently a specialized service for
the Parliamentary Web site, but it was designed to be replicated and used
as widely as possible.

IBM Scientist Predicts Software's Future
ZDNet Asia (06/05/08) Pinaroc, Joel D.
IBM chief scientist Grady Booch says future software development will lead
to bigger, more pervasive, transparent, and advanced programs that cater to
the growing complexities users will demand. Booch says that unlike
previous generations, today's software developers do not have to worry
about infrastructure and computing power, allowing them to build
applications that are far more complex and powerful than previously
possible. Booch also predicts that future computers will become
increasingly faster and microchips will eventually use atoms-to-transistor
systems, providing unprecedented computing power. Programmers will benefit
from a reliable global Internet that will allow for new levels of software
collaboration, particularly as wireless connections become more ubiquitous.
However, he says some questions still remain, including what future
software will look like, how programmers will build such massive programs,
how technology companies will distribute software, and what will be the
value proposition of such complex software. Booch also says the human side
of programming will remain an issue, with factors such as computing power
and the right infrastructure not being a guarantee that software engineers
will create the "right" software, which hinges on a programmer's
innovation, imagination, social skills, and the ability to realize
important issues and address what users may want in the future. Booch also
predicts an unprecedented growth in data, driven by the Internet, which
will play a significant role in how programmers design software.

MIT Creating a Car That Helps Drivers Make
Decisions
Boston Globe (06/02/08) Batog, Jennifer
Researchers at MIT's AgeLab are developing the Aware Car, a car that can
help people be better drivers. The black Volvo SUV contains mini-cameras
and infrared lights mounted above the steering wheel to monitor the
driver's eye and eyelid movements, wires stored in the console to monitor
the driver's heart rate, blood pressure, and respiration, and a device in
the trunk that monitors lane drifting. Data from the devices can be
displayed in real time on a computer monitor. AgeLab researchers are using
the $1.5 million vehicle to determine how to combine existing technologies
to create a car that could help drivers, particularly older drivers, be
safer, and help automakers design safer cars. AgeLab director Joseph
Coughlin says an aware vehicle would perform better because it would know
and understand the driver's habits and could react when the driver alters
those habits. MIT's research is aimed at developing vehicles that could
coach drivers to make better decisions based on data about how they are
driving at that moment. For example, lane sensors and eye monitors would
determine when a driver is getting too tired and the car could advise them
to pull over, and biorhythm monitors could alert monitor a driver's health,
such as blood sugar or heart rhythm, and alert the driver of warning
signs.

Here's Looking at You, Kid
Nature (06/01/08) Vol. 453, No. 7196, P. 708; Merali, Zeeya
An algorithm that measures the quality of new screenplays and compares
them to successful scripts in the same genre by uncovering structural
patterns has been developed by a scriptwriter and a pair of University of
London computer scientists. The software analyzes the frequency and
placement of each word in the screenplay, and finds common patterns in
popular scripts such as "Casablanca" and episodes of "CSI." For example,
in such scripts the tension mounts in waves by shortening the length of
successive scenes in blocks to produce "mini-cliff-hangers" that are
resolved in a longer denouement. The algorithm can also identify how
conflict-imbued incidents are distributed throughout the plot by examining
how the locations of groups of frequently used words change in relation to
each other. To test the algorithm's predictive abilities, the team altered
the script of "Casablanca" to create versions with the same plot but a
divergent scene and sub-scene structure so the program would project the
resulting film's lack of success. The algorithm's developers hope to blend
it with existing automatic screenplay formatting software, and screenwriter
and co-developer Adam Ganz believes "we have the potential to separate the
truly innovative from films that are superficially innovative but have no
deep structure." Screenwriter Amanda Holiday thinks the algorithm could be
an excellent tool for rewrites. The group that developed the algorithm has
set up a Web site where writers can upload their scripts for preliminary
analysis and study frequently occurring word clusters in various popular
films.
