Virtual Reality Examples Architecture actually walk into building and look around (instead of more traditional direct manipulation looking at it from various directions and perspectives) Possible - medicine On the boundary real flight simulator
Example: Firefighter TrainingFirefighter Training This system will simulate the progress of a fire in a single family dwelling 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 environment. 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.
Example: Meditation ChamberMeditation 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 experience. 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
Example: 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 15-20 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 features
Example: Virtual Reality Phobia Therapy 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.
Example: Helping Burn Patients Cope with Pain using immersive VR for pain control (in addition to pain medicine). Their first virtual world used was SpiderWorld. Spiderworld was originally designed to treat spider phobics, but has also proved quite distracting for burn patients.treat spider phobics now developing several new virtual environments specifically designed for treating pain (e.g., especially attention-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.
Example: Virtual Gorilla Exhibit Virtual Gorilla Exhibit being developed to explore techniques for using Virtual Reality to present information to users experientially that would otherwise be difficult for them to learn. Based upon actual data from the Zoo Atlanta gorilla exhibit, modeling an environment where the user can explore areas that are normally off limits to the casual visitor.

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 scanning an image directly on the retina of the viewer's eye, 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-of- view, high resolution, high brightness, low cost virtual display. http://www.hitl.washington.edu/research/vrd/project.html
Progress on Movement Sensing For some applications, a hands-free, body-operated walking interface is ideal; the UW HIT Lab has been developing prototypes of "sufficient-motion" interfaces, which allow the user to interact by using a subset of the real-world kinesthetic inputs. 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 augmented reality, the overlaying of virtual objects on the real world, can radically enhance face-to-face and remote collaboration. 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-to-face and remote users to collaboratively interact with each other and virtual animations. http://www.hitl.washington.edu/research/shared_space/
