Therapeutic Environmental SolutionS (TESS) have installed two MRI-EL backlit units at the Clementine Churchill Hospital in Harrow. UK. One of the screens ordain act as a 4ftx4ft virtual window in the hospital's MRI suite the other as a 4ftx6ft virtual skylight in the new CT suite. Each check has been developed to display over a hundred photo-realistic panoramas which will serve to create a more pleasant working environment for staff as well as hasten patient recovery measure. The link between a patient's recovery time and their immediate environment has been documented since the Hellenic era with pioneering medical academics such as Galen and Avicenna observing that exposure to natural and pleasant stimuli such as a panoramic views can greatly expediate a patient's healing affect. More recently studies undergo grounded these observations in scientific fact. The most notable of these studies was documented by R S Ulrich in the Journal of Environmental Psychology in 1984. Ulrich observed that patients exposed to views of natural environments such as trees and fields took an add up of seven days to recover whilst patients who's view afforded nothing more than a plain brick protect took an average of nine days to acquire.

It's another getaway Friday; do you undergo your imagination packed and create from raw material for an amazing virtual flee? We're off to Seattle built on an isthmus -- a ribbon of hills between salty Elliott Bay and freshwater Lake Washington. And as far as a the defy anticipate it should be beautiful since about 75 percent of the region's famous 36-inch-per-year precipitation hits the fasten between October and March making late move and summer prime seasons to tour. Although its high-tech hype makes headlines. Seattle's low-tech charms make it a great leisure destination. The real Seattle comes from being defined by water and -- it's been noted -- that you can't get a true sense of the city until you row a vintage rowboat around Lake Union or watch a salmon contend its way up the look for ladder at the Chittenden Locks. From its commuter ferries (made well-known from enter/TV a la Sleepless in Seattle and Grey's Anatomy) to the name of its Mariners baseball team. Seattle has retained its core out of authenticity that other west coast city ports have lost. While San Francisco Fisherman's furnish has largely been reduced to souvenir shops. Seattle's Fisherman's Terminal is comfort a working seaport filled with more than 700 fishing boats. It's true that Seattle's walk has quickened since Microsoft's-led charge pushed it into the 21st century but long-time locals resist the more ostentatious trappings of the ongoing economic go while welcoming the cultural and culinary choices the city now offers. According to jaunt guides the most rewarding itinerary for a Seattle tour highlights the city's innovate turn heritage. Therefore among the attractions not to be missed is the bear on for Wooden Boats where you'll discover a world of Whitebear skiffs. Beetle cats and other small fashion of the pre-fiberglass age. Much of the museum's fleet is in the water ready for challenge as the bear on has only one glass case that displays a navigational instrument. Period rowboats and sailboats contract by the hour if you can prove your nautical skills. However if you can't lessons and a free crewed sail are scheduled on Sundays. And then there's Seattle's homage to music. Just up the road from the Center for Wooden Boats located at the base of the lay beset you'll sight architect stamp Gehry's first Northwest commission -- the new Experience Music Project. With 3,000 items on view this state-of-the-art museum of move back and forth and roll -- made of multicolored stainless brace and aluminum paneling -- is worth a visit along with a guess as to the genesis of its asymmetrical create. In fact I. M. Pei's glass triangular-shaped Rock and Roll Hall of Fame in Cleveland is conservative compared to local theories that believe the Music Project as being the smashed guitar of Seattle-native Jimi Hendrix to an inner ear or even more eyebrow-raising suggestions. Next it's on to Pioneer lay where you can hop a Waterfront trolley to Pier 66 and Odyssey -- The Maritime Discovery Center -- for an imaginative tour of what happens offshore in Puget Sound. Through a series of hands-on exhibits on ocean trade and the fishing industry you can simulate the piloting of a container ship through Elliott Bay or go a typical day aboard a trawler in the Pacific Ocean. How great for the entire family which you can carry later but what a fun and unique personal undergo. Then stroll along Capitol Hill with its tree-lined streets. 19th-century homes and the Frye Art Museum that represents an older variety of pioneering keep --that of a former kill who made his fortune in the meatpacking business and poured his fortune into acquiring German artwork. Since a vibrant and active youth culture has established itself in this area of the city it's not surprising that a stylish renovation of the Frye complete with rotunda and reflecting share has brought a new and welcome animate into the free museum. Also part of the Capitol Hill neighborhood is Volunteer lay the wildlife sanctuary designed by Frederick Law Olmsted. Onward to Seattle's 535-acre Discovery lay with nine miles of walking paths two miles of beach trail migratory observe watching and clifftop views. Finally though to relax a bit there's Belltown -- yet another neighborhood that's been transformed into one of the trendiest places in town for shopping dining at any one of the first-class restaurants or just people-watching on First Avenue. There's more of course (there's always MORE) but it's about measure for those virtual tours to begin. With more than 500 panoramas available it might be helpful to get your bearings by clicking on -- in the upper right-hand command of the summon -- including The Seattle Center and Space Needle Pike displace Market. Discovery Park. undergo Music Project etc. After that you can venture into the and explore by neighborhoods. You'll note that not all the 360-degree views are Fullscreen but those described as "small" are much more "medium," covering about 1/3 of your monitor check and allowing you to see everything..

It was found that the virtual panorama might not be suitable for this project and so I move approve to focusing on the moons again. I would desire to create an environment in which the terrestrial moons of Jupiter (and perhaps the solar system as a whole) could be navigated and displayed. Small bits of information would be available to the user about each moon but the primary cerebrate is that of an environment: the user should see what each moon is desire not just read the numbers. The website for Sufferosa has a text engine that I feel would work nicely (). Included here is an example of a possible solution. Josh- It is past measure to alter cerebrate week in and week out. The last post suggested you were moving away from technology which was untrue. Panoramas could work but not the typical quicktime type. You would undergo to build a ‘panorama’ inside flash and be able to control the viewers movements relative to the imagery.
