phases of maturity for VR application

demonstration, pilot, in production (no furhter testing)

emerging and traditional VR markets

Traditionalmarketsare medical, entertainment/arts/education and defense/aerospace


Emerging markets are manufacturing, oil/gas exploration, datavisualization;

five uses for VR, going highest to lowest.. difference in US, EU, other continents

training/education, research, business services, entertainment, communication. in US, highest to lowest in that order pretty constant d/dx. europe, top three are even. other contiennts nada

some medical applications for VR

mistakes on VR patients, cheaper, enjoyable treatment, model and study rare cases

why need interactive VR for medical training ?

Interactive anatomy teaching is needed since cadaver training isnon-repetitive and scarce;

Visible human dataset. what is, problems ?

the first completely realistic model forboth male and female; Is a de-facto standard for algorithm comparisons;;; It is however huge, so cannot be rendered in real time. Needsmodel segmentation and decimation.



four stages of medical VR apps

diagnostic and triage -> anesthesia -> surgery -> rehab

system architecture of VR medic training

slide 14

how does EMR VR training in this one, horrible specific and outdate example account for lack of dexterity when grasping objects

objects are attracted to the user's palm, objects are intelligent. queried about their status (flashlight on/off)

EMR VR what drives patients ?

a finite state machine that reacts to the progression of specific disease user's actions

what did the EMR human factors study do well, poorly ?

high scores to vital signs, pt appearence, applicability //// lowest to handling objects, difficutly

butt exam, what used, how'd they compared to control, interesting to note

a phantom interface, SGI workspace, (graph on slide 21) // all did worse than control, novices did better, masters did faster. // masters learned limitations of tech, not new task. smaller std deviation. better learning (only had to adapt to VR, not to a whole new thing)

endoscopy VR applications

sweet new way to do colonoscopies developed at SUNY. drink special drink, normal CT image, computer de-poos the image, adds contrast. fins 5mm+ polyps as good as normal. 3mm harder to see. ..// IV trainer

why need VR app for endoscopy:

The are invasive procedures, require patient anesthesia, and canlead to injury, if done badly;

why need VR app for IV training

Insertion of IV is leading cause of infections and discomfort for patients. Present teaching methods are inadequate and nurses learn onpatients…

anastomosys;

suturing two blood vessels.

who developed an anastomosys VR training pilot ? using what physical equipment ? how ere vessels modeled ?

how'd the increase realism?

Boston Dynamics.stereo glasses, mirror, two PHANToM arms. TELEOS spline-based toolkit. trainee holds real tools.

the HF study of the boston dynamics anastomosys trainer showed what ? what variables were mesaured ?

possible use in certification; was able to rate surgeon skill accuaretly. Time/.accuracy////angle error///peak force//tissue damage//surface damage//overall score

HF study, boston dynamics, anastomosys: difference between surgeons and students ?

surgeons has much less tissue damage, less learning, more uniformity (little SD), students FOR ONCE did poorly in everything compared to surgeon.

HF study, boston dynamics, anastomosys. graph that shows overall learning as a function of ovearll score.

slide 50

what is MIS ? 3 pros, 3 cons for surgeon

minimally invasive surgery. PROS: less hospital stay (from one week to less than one day);less scarring (three 1-2 cm cuts);faster recovery. CONS: loss of direct (3D) view of the cutting area – has to look at a 2Dmonitor;loss of tactile feedback, which is filtered by the laparoscopicinstrument (stick with a handle);the “fulcrum effect” due to the orifice in the body

fulcrum effect. what is it ?

using a lapropscopic instrument, controls are inverted. diagram on slide 53

what does laproscopic VR trainer not have?

force feedback.

MIST VR: what two trials used to assess accuracy in finding skill ? how ? draw graph (slide 58)

(Minimally invasive surgery trainer): the Taffinder and the Gallager. Taffinder: three groups; real surgeons, training surgeons, non surgeons. did a bunch of tasks. time/accuracy. experts did way best. mapped to skill, win. gallager: two groups novice surgeons, trained on MIST VR and not. burned lines in paper. trained on MIST VR was OP. Better accuracy, MUCH BETTER SD 30% increase.

upgraded MIST VR is what? hwy is it better ? what software used for graphics ?

“LaparoscopicSurgical Workstation,”force feedback for insertion, pitch, yaw,handle twist and handle grip;Works with a PC, being connected over a PCI card.Has more realistic graphics (through “LapSym” software).

what is VR rehab used to treat in a psychological setting

Used to treat eating disorders, post-traumatic stress disorders, andphobias;

VR phobia training PROS

on a PC in doctor’s office (privacy);safer (like fear of spiders or snakes);cheaper (no need to take patient on an actual flight).

feat of flying therapy tech developed where? what use ?

georgia tech and Emory university. and HMD and PC, software is a FSM

Fear of flying therapyFSM diagram

slide 76. goes through five stages: taxi, take off, level flight, aborted landing, landing.

another psycho treatment for... can diagnose..

alzheimer's, TBI, ADHD. can diagnose ADHD.

three types of learning in VR

“constructivist,” “constructionist,” and “situated.”

Constructivist learning, what is, example

involves exploration of pre-built world;Example is CyberMath developed in Sweden for college students

another example of construstIVIST learning, one pro

Another example of exploration-based learning is the VirtualPhysics Laboratory to teach high-school students Newtonian andQuantum Physics;Students interact with the simulation using a sensing glove andvirtual control panels. Students are more motivated and understand3D concepts better compared to other methods of instruction.

Constructionist learning, what is, example

involves active building of a world;An example is the NICE project to teach gardening to elementaryschool children; they used a CAVE and ImersaDesk to interact withVEs showing a virtual garden.

what is NICE and what does it use, what does it teach ? (VR in education)

it is a world building tool. Uses a CAVE and Immersa-desk to interact with virtual environment. teaches gardening.

in the NICE HF study, how did they separate the participants, did it work, who learned the most ?

52 second graders, groups with a leader (only leader used the sim), avatars represented the leader and the intelligent agents. (plants.) kids learned 12% up to 35% (after), leaders learned the most.

what the F does VR have to do with art ? 4

new medium, allows preservation in VR, can explore art and new ways to experience it, increased access of art in virtual museums

what statue did IBM recreate, with what ?

Virtual Florentine PietàOriginal statue created by Michelangelo in the XVI-th Centuryas his tomb monument;Recreated in VR by a team at IBM over a period of two weeks,using stereo scanners and co-registered color digital photos toproduce a mm-level of detail.

what did IBM do with the virtual statue? how'd they change it? what's a pro for studying ?

A 3-D viewer (low resolution) allowed interactive frame rates ona laptop – for art historians;Views not possible in a museum;The statue was “restored” in VR – adding missing parts;It was placed in context – in a virtual mausoleum.

how does the virtual heritage network make a recreation ? how did they increase realism after ?

phase 1: look at architectural plans, historical texts, site visit. phase 2) take photographs for things not in blueprints, and for textures. phase 3) light measurements to get accurate radiosity. phase 4) Two models made using 3D studio max, inside and outside. phase 5) link the two models with a portal for better render speed,. // A custom VRML extension (to allow multi-texturing) but it reduce framerate to garbage.

what else has been modeled in vr ? why notable ?

notre dame, modled in unreal engine.. usually for games. has a friar tour guide scripted AI, gives talks based on proximity to notable stuff.

examples of VR in entertainment

phones w/ camera sensors (tiltaworld), disneyquest (pirates game with passive tactile feedback, stereo graphics). //“Virtual Jungle Cruise” on inflatablerafts. Pneumatic motion platform, sensorized oars and water spraysadd to the feeling of immersion.
