Back for another year, DesignFest continues to provide
an opportunity for you to learn more about object oriented
design by doing design. DesignFest is about sharpening
your skills by rolling up your sleeves and working on a
real problem with others in the field. You can expect to
interact with everyone from total beginners to textbook
DesignFest is a free event (for conference registrants) created
to give OOPSLA attendees the opportunity to learn more about
design by doing it. Participants are organized into small groups
to solve a particular problem.
Each team has a moderator and a recorder.
The moderator is responsible for making sure the team makes
progress, without leading them in any particular direction.
The recorder is responsible for recording the design the
group produces and what they have learned.
The problem descriptions will be distributed at the start of
each DesignFest session, along with a timetable, process hints,
and a list of deliverables. Each team should produce a poster
that summarizes their work. The posters will be presented
at the end of the conference for all conference attendees to view.
To register, please fill out the DesignFest section of the
OOPSLA registration form. Registration for DesignFest is free if
you have registered for the conference.
Be sure to include your e-mail address.
You will be contacted by e-mail at
a later point in time with regard to selecting a design problem,
preference to work on an XP team,
and possibly a team meeting time.
You are invited to take a tour of the previous DesignFests
The DesignFest Committee appears in the Conference Committees
section of the Program.
Note that all DesignFest sessions are
separate sessions, lasting half a day or a full day.
The following problems have already been selected for this year.
- Advanced Peer To Peer Discovery and Interaction Framework
Peer-to-peer (P2P) architecture is a new paradigm in distributed
computing technologies. Peer-to-peer computing is the sharing of
computer resources and services by direct exchange between systems .
The desired framework based on peer-to-peer network should provide
peer discovery and interaction mechanisms. The framework also allows
the peer computers to share files and exchange instant messages.
It can serve as a framework for distributed file sharing and
messaging systems based on P2P. The framework should be generalized
enough to cater to needs of any specific P2P application.
- MRI Visual Analyzer System
The problem is to design and implement a friendly platform
for MRI visual analysis to be used by medical professionals.
The application should enable doctors to see the result of
MRI as three-dimensional objects. It also provides them the
opportunity to access various parts of the organ and study
it from different points of view. There are more features
such as measurement, opacity, and coloring that make the
application useful by achieving a more precise, fast,
effective, and easy to understand vision of the organ's
- BifCo Panel Repair
BifCo repairs two-dimensional structural panels using
a robotic arm assembly in an environmental chamber.
While there are several components to this system, your
team has been hired to design the motion control subsystem
(MCS) for the BifCo repair system. The MCS is responsible
for managing all motion control and status requests submitted
to the motion control hardware. The repair process dictates
several motion constraints. First, only damaged zones of a
panel require repair. Second, the repairs must be done
without totally disassembling the panel - so in addition
to defining the section to be repaired, exclusion zones must
be observed for features that protrude from the assembled
portion of the panel. Third, the robotic arms must stay
within the walls of the repair chamber. These features are
recorded by a separate subsystem and are inputs to MCS. You must
design a system that supports all robotic motion: "Manual"
moves commanded by the operator, and automatic motion that
moves the tool back and forth across the repair zone a segment
at a time, from the starting edge to the end of the repair
zone. The MCS must support a separate graphical display
subsystem by being able to draw zones of work, exclusion
zones, the real-time position of the robot's arms, and the
end position of robot arms on a device context provided by
the graphical subsystem.
- MultiBatt - The Outer Space Battle Game
You are to design a massively multi-player game that
takes place in a shared, 2-dimensional, virtual space.
Each player is at a separate work station, and navigates
one tank-like vehicle through this space. The space
is made visible through a graphical window. Player vehicles
appear in this window, and are updated in real time.
Vehicles have the capability of shooting missiles. If
enough missiles hit a vehicle, it is destroyed and the
player is eliminated from play. Display is managed by the
game software. The game system to be designed will manage
distribution of player state among the various players.
The game system must also manage player interactions
such as missile hit determinations.
- Data Collection in the Forest
A local forest technology company, Forests 'R' Us, wants
to build and sell a system for gathering and analyzing
weather information to predict forest fires and help with
water table management. The Arbor2000 will be sold to
National Forests, Environment Canada, the U.S. Forest
Service, and large private land owners. It will consist
of hardware and software both locally in the owner's
office building and remotely in the forests.
