Firefighter Training

This system will simulate the progress of a fire in a single family

will respond to actions made by the user to rescue occupants and
put the fire out.

The user of the VE will be a Fire Company Officer being trained
or evaluated for his/her skills at commanding a fire crew.

In the VE, the user will speak commands that are translated by an
operator into a predetermined animation sequence in the virtual

As the fire company officer issues commands, the virtual fire crew
will go through animations reflecting these commands,

fire burns in response to virtual crew actions.


Meditation Chamber

The goal of this research is design and build an
immersive virtual environment that uses visual, audio,
and tactile cues to create, guide, and maintain a
patient's guided relaxation and meditation

The use of meditation and guided imagery is well
established as helpful in the treatment and prevention
of a number of diseases

The possibility of increasing the effectiveness and
repeatability of this type of therapy

This project is aimed at creating a working prototype
of this system


Virtual Geographic
Information System

VGIS (Virtual Geographic Information System) is a
large, multifaceted project to allow navigation of and
interaction with very large and high resolution,
dynamically changing databases while retaining real
time display and interaction.

The system allows users to navigate accurate
geographies with sustained frame rates of 15
frames per second.

The user can not only see these terrains from any
viewing angle but also buildings, roads, high
resolution imagery draped on the terrain, and other


Virtual Reality
Phobia Therapy

Virtual Reality Exposure involves
exposing the patient to a virtual
environment containing the feared
stimulus in place of taking the patient
into a real environment or having the
patient imagine the stimulus, which is
what traditional exposure therapy
usually involves.


Helping Burn
Patients Cope with Pain

was originally designed to
treat spider phobics
, but has also
proved quite distracting for burn patients.

now developing several new virtual environments
specifically designed for treating pain (e.g., especially
grabbing virtual environments).

SnowWorld has been developed with support from the Paul
Allen Foundation for Medical Research.

Patients fly through an icy canyon with a river and frigid
waterfall. Patients shoot snowballs at snowmen and igloos
(with animated impacts).

Since patients often report re
living their original burn
experience during wound care, SnowWorld was designed to
help put out the fire.

U Washington Virtual Reality Projects

Progress on Visual Display

The Virtual Retinal Display (VRD) team has been focused
on developing improvements to the current prototype
systems and on creating the parts needed for future
prototypes. The VRD, based on the concept of

an image directly on the retina of the viewer's
was invented at the HIT Lab in 1991. The
development program began in November 1993 with the

goal of producing a full color, wide field
view, high resolution, high brightness, low
cost virtual display.

Progress on Movement Sensing

For some applications, a hands
free, body
walking interface is ideal;

the UW HIT Lab has been developing prototypes of
motion" interfaces, which allow the user to
interact by using a subset of the real
world kinesthetic

Though the ranges of motion are less than full, these inputs
are sufficient to convince the user that he or she is moving
in the virtual world.

Development of these interface devices is called the Virtual
Motion Controller (VMC) Project.

Virtual Motion Controller

The HIT Lab's VMC working
prototype measures body position
over the working surface with an
arrangement of four weight sensors

The curved working surface provides
important feedback to the user about
his or her physical location, and
therefore body locomotion input to
the device.

Progress on Cooperative
Augmented Reality

The Shared Space interface demonstrates how
, the overlaying of virtual objects on the real world, can
radically enhance face
face and remote

For remote collaboration, system allows life
sized live virtual
video images of remote user to be overlaid on the local real
environment, supporting spatial cues and removing the need to
be physically present at a desktop machine to conference.

computer vision techniques are used to precisely register virtual
images with physical objects, extending the currently popular
"Tangible Interface" metaphor.

work in the context of a collaborative card
game application that
allows face
face and remote users to collaboratively interact
with each other and virtual animations.

Science Fiction?

Most of this stuff won’t be in an office
near you next year …

But the future comes quickly in computer
science !
