  1. VR Applications Jyun-Ming Chen Fall 1999

  2. medicine rehabilitation entertainment military business robotics manufacturing ... anatomy trainer surgical simulator wheelchair-VR talking glove chemical design flight simulator battle training interior design tele-operation Application Domains

  3. ... the medical knowledge has improved a lot, but the teaching methods haven’t changed much... http://www.avrs.com/~antares/antares/cadaver.html [visible human project] Anatomy Trainer

  4. Films on Medical Applications

  5. Military & Aerospace • Simulation & training • Increased technological complexity • remote/team simulation • require flexible, upgradable, networkable technology • Typical applications • troop training • battle preparation • mission debriefing • new weapon preparation

  6. Motivation DARPA projects reduce training cost increased safety reduce environmental impact Details partially immersive M1 tank, with navigation, weapons, sensors, displays resident computer keeps a copy of battle field trees, roads, buildings,... communication: intercom; voice/electronic msgs dead reckoning to minimize network traffic SIMNET tank trainer network

  7. trainee practiced enemy force 3 times their size SAFOR (semi-automatic forces) enemy forces act as intelligent move in pre-programmed formation stealth vehicle observer on the battle can recreate the real battle; use the data for subsequent training SIMNET

  8. Motivation radar display produce operator overload create new displays that are more natural to understand 3D ASW system stereo, hi-res HMD + 3D Sound gesture+ voice controlled ASW antisubmarine warfare

  9. plastic mock-up stinger 3D mouse to track pos/orient of launcher simulate weapon firing sequence, missile flight characteristics, target behavior keep track of hit/miss ratio Virtual Stinger Trainer

  10. Motivation zero gravity activity is complex & challenging object manipulation is unpredictable under water buoyancy, but with water friction airplane step descent short periods of time Work space shuttle extravehicular activity Hubble space telescope repair & maintenance trainee sits on sensorized chair HMD (telescope, shuttle, sky) data glove to grab instruments thruster control Astronaut Training

  11. Motivation with modern weapons, displays, avionics, pilots suffer from sensorial overload use VR to study the best man-machine interface Design Issues network pilot state monitor voice command display quality (texture mapping) mission management tactile feedback using see-thru display with real control panels Virtual Cockpit

  12. Films on Aerospace APs

  13. Business • advertising: • VR promotion: “leading-edge” products • office building walkthrough • finance: data display • teleconferencing • litigation • realistic reconstruction of scene

  14. interactive & immersive visualization of n-dimensional data nested Cartesian coordinate system f(x1, x2, x3, x4, x5) with origin at (x3, x4, x5) construct f(x1, x2, [x3, x4, x5 ]) currency exchange f(price, time, foreign interest rate, ...) HMD + Data glove grab inner graph within outer C.S. n-Vision

  15. Besides walkthrough lighting design radiosity quantitative results (lux) Lightscape Interior Design (I)

  16. air conditioning modeling visualize airflow to ensure that air-velocity and temperature standards are met Using Division distributed computing Interior Design (II) Living Environment System Lab (Matsushita)

  17. mechanical arm with great versatility can be self-adapting; react to changes of the environment two types: industrial (structured environment) service (unstructured; under human control) VR applications off-line programming realistic modeling of robot & environment test on virtual robot then download to real robots Tele-operation Robotics

  18. human in the control loop shield operator from dangerous environment historically precedes VR; but VR can help operator training information of on-line control synthetic imaging to aid visualization real image may be corrupted (steam, smoke, insufficient lighting move-and-wait: phantom robot provides a visual cue Tele-operation

  19. traditional CAD: geometry aspects with VR life cycle concerns: safety, ergonomics, maintenance, assembly reduce the number of full-size prototypes Product Design

  20. Product servicing superimpose textual and graphical info over the image of serviced product also used in training Plant Design use VR to help the positioning of equipment on the plant floor for best production component flow Other Manufacturing

  21. Review Questions • Propose your final project in class in the format demonstrated (15 min). • Survey “visible human data set” • What is dead-reckoning and how does it help reduce network load? • Find another application of n-dimension data visualization.
