"MJ" Tavantzis
is a senior and will graduate with a Bachelor’s degree in Computer
Science and a Master’s degree in Cognitive and Neural Systems.
This summer he is working with Professor Azer Bestavros from the Computer
Science Department.
MJ first became interested in participating in UROP in Fall 2002.
He applied for and received NSF-REU funding for the summer to work
on a project with a professor in the Psychology Department. This summer,
he is working on a new project with the help of UROP funding. MJ came
up with the idea for his current project while sitting in CS-350, a
computer science class he was taking during the 2003 Fall semester,
in which Professor Bestavros mentioned the CS department’s "Sensorium"
project involving the use of large number of networked video sensors
for various applications. He then decided to talk to the Chair of Computer
Science, Professor Azer Bestavros, to get his opinion about his idea.
Professor Bestavros loved the idea and encouraged MJ to pursue his
project and apply for UROP funding.
MJ’s idea (and current project) is called VISIAD, Virtual Space
Information Association Device. VISIAD would store information about
events happening in a person’s environment in a database, which
could later be accessed through a video camera screen or a heads up
display (HUD). For example, when a student is on campus, he or she
could see what events are happening around their location. When a person
looks through the VISIAD device, the virtual information would be overlaid
onto their environment. The goal of his project is to make it appear
as though the information is part of the real environment. MJ can usually
be found in the Context Aware Lab at the MIT Media Lab working with
his friend, Cristina Domnisoru, an MIT student, who shares the same
interest in the VISIAD project. In addition to getting advice from
Professor Bestavros at BU, he is also able to get feedback and help
from MIT professor Ted Selker and other graduate students who are also
interested in the same type of technology.
The VISIAD system is similar to the Internet in that both provide
easily accessible information. However, the VISIAD system has the potential
to be more useful and practical than the Internet. Unlike the Internet,
this project will enable people to retrieve information that is directly
relevant to their physical location. A person would not have to conduct
time-consuming Internet searches, but instead only need look on their
own VISIAD device to find the information they are seeking. MJ hopes
that with more research, this device would become widely available
for consumer use. He believes that this could be done as early as 5-10
years from now. The project has received interest from Nokia who will
donate phones to have VISIAD implemented on. Also, a French eyeglasses
manufacturer will be providing glasses with special heads up displays.
The biggest challenge that MJ has faced with is known as the "registration
problem." In other words, to make the virtual objects and information
appear seamlessly with the environment around a person, the device
needs accurate information about the environment itself. The device
needs to know the exact positions of everything around the person in
order for the virtual information to be in the right places. The best
methods to obtain positional information are to use local sensors,
cellular phone networks, and gyroscopes. However, MJ must integrate
complex algorithms since those methods are not entirely accurate in
and of themselves.
MJ says that the best thing about his project is that it is "fun"
to work on an idea that he came up with. He believes that he feels
freer with this project since he does not have to work on somebody
else’s
idea and follow their research line. Also, since this is his vision,
it motivates him to work harder and enjoy it more. He says that without
UROP, it would have been much harder to make his vision into a reality.
UROP also encourages students to be more innovative outside the classroom.
As a computer science major, he has learned a lot about different
hardware and the machine language that are fundamental to his project.
However, since he is now working hands-on with the hardware and creating
his own programs, he feels that he is obtaining a deeper understanding
of everything he has learned in the past. Also, in order to better
understand and work on his project, he went to the University of Maine
in Orono (where he is from) last summer. There, he learned more about
hardware and electrical engineering in order to supplement his knowledge
gained from his BU coursework.
In the future, MJ sees himself conducting brain research. This will
allow him to use his technical background in both computer science
and cognitive and neural studies. He believes that his participation
in UROP has helped him to discover that research is what he wants to
do as a career.
His advice to students who want to become involved with research of
their own is to just take a chance and apply to UROP. He believes that
if you have an idea of your own you should be proactive and contact
professors, other universities, and "think out of the box" to
make your vision happen.
