patient with spinal cord injury may not be able to control a

to develop a brain computer interface (BCI) for which neural
signals from the brain are sensed, amplified, filtered and
decoded to control prosthetic limbs, electric wheelchairs,
or other external devices, leading to a dramatically
improved quality of life.
BCI is defined as the science and technology of intelligent
devices and systems responding to (1) neural processes
in the brain that generate motor movement and (2)
cognitive process (e.g., memory) that modify motor
movement. Today, with advanced technologies in medical
sensors, biocompatible materials, integrated circuit and

focuses on “minimally invasive” BCI technology using

second drawback with this system of Fig. 2a is that the

find solutions to these problems. Their approach is to

compression and telemetry) on a tiny piece of silicon. This

Robotics Institute Research Professor and ICES faculty

recipient of the Steven J. Fenves Award. The Fenves
Award is awarded annually to a faculty member who
makes a significant contribution to systems research in
areas relevant to ICES. This award will be presented to Dr.
Weiss at the Carnegie Institute of Technology (CIT) Faculty
Awards Banquet this spring.

The second sub-system (Fig. 2(b)) is a robust decoder
that takes the recorded neural signal as input and
accurately predicts the kinetic parameters (e.g.,
direction, velocity, etc.) of targeted movement. Instead of
considering the neural signal decoding as a general signal
processing problem, we particularly focus on the aspect
of hardware implementation with high mobility. Namely,
the algorithms used for neural signal decoding must be
implemented in hardware with small dimension, light
weight and low power.
The long-term goal of this project is to develop advanced
micro-system technologies and apply them to clinical
applications. Through collaborations with several multidisciplinary groups with Carnegie Mellon, the University
of Pittsburgh Medical Center (UPMC) and the Allegheny
General Hospital, this project will eventually lead to
intelligent devices and systems that aid disabled people

engineering research with an impact on the real world.
His service of three-plus decades at Carnegie Mellon
reflects his unparalleled quest for bringing people of
different backgrounds together by trail blazing new areas.”
Dr. Weiss has been a contributor to systems research
since before the existence of ICES and the NSF EDRC
(Engineering Design Research Center). “He has been
the keeper of the spirit of ICES by reflecting its goals and
by being an exemplar researcher for others to follow,”
continues Dr. Fedder.
The “Steven J. Fenves Award for Systems Research” is
presented annually to individuals for their contributions to
systems research in areas that are relevant to the College
of Engineering and ICES. Individuals considered for this
award have made significant contributions to systems
research in areas relevant to ICES, by furthering the goal
of interconnecting people, physical, and information;
development and demonstration of an engineered system;
enhancing education in systems through the development
of courses, publishing textbooks, or a body of knowledge
that is of pedagogical importance; and causing a
paradigm shift in systems research.

ICES Research Professor Asim Smailagic, Director of the
Human-Computer Interaction Institute Dan Siewiorek,
and Pitt Psychology Professor Thomas Kamarck have

ScienceDaily and EurekAlert for their work studying the
effectiveness of the eWatch, a wrist-mounted instrument,

about the size of a large wristwatch, was developed by
Professors Smailagic and Siewiorek and is one of the
wearable products they have created in the Interaction
Design Studio and Wearable Computers Lab, of which Dr.

Professors Smailagic, Siewiorek and Kamarck have

participant in the study with an eWatch. The eWatch can
detect sound, motion, lighting, and other factors. Every
45 minutes during a five day period, the eWatch prompts
wearers to take part in a brief interview, recording their
responses to questions about their current events.
The eWatch was first developed as a class project in Drs.
Smailagic and Siewiorek’s Rapid Design and Prototyping
course in 2004. The development and refinement of the
eWatch was made possible by Pennsylvania Infrastructure
Technology Alliance (PITA) funding. This funding also allowed
for the continued collaboration of the LINCS lab work with
local industry including BodyMedia, a company specializing
in wearable biometric data collection devices, Inmedius,
Intel, Bosch, and R.J. Lee Group.
Over the last decade the Interaction Design Studio and
Wearable Computers Lab have collaborated in design and
prototyping of more than 30 wearable and context aware
systems, which have become cornerstones of the wearable
computing field. For more information on the eWatch

This collaborative research project was initiated in
July 2005 and continues with the aid of Pennsylvania

outreach update
ICES Outreach Receives Media Attention
during National Engineers Week
On February 15 and 16, ICES participated with other
Carnegie Mellon departments and local organizations in the
National Engineers Week outreach activities at the Carnegie
Science Center. The ICES table was manned during
these days by ICES faculty, staff, and students who worked
with visiting children on the activity “Build a Bone.” This
problem-solving activity gives participants a list of materials
and parameters they must follow as they attempt to create
a bone that will hold the most weight when tested. This
year, a new record was set for the strongest bone, which
held 24 lbs, and it resulted in attracting the media attention
of WQED’s Rick Sebak.
Sebak, who creates documentaries about Pittsburgh history,
was filming at the Science Center on Friday for a new
documentary called “Invented, Engineered, and Pioneered
in Pittsburgh.” His film crew captured on tape the testing
of the strongest bone by its young creator and by ICES
Associate Research Professor Phil Campbell, who was
working at the ICES table. Professor Campbell created the
Build a Bone activity for National Engineers Week and is
the ICES faculty coordinator for National Engineers Week
activities at the Science Center. The documentary will
premiere on WQED on Thursday, April 10.
