The researchers will showcase their technologies at a booth in the Imagine Technology Pavilion at the Marriott Wardman Park Hotel, 2660 Woodley Park Road N.W. They are among representatives from 32 companies and research universities participating in the exhibition.

The Carnegie Mellon/Pitt display will include:

• Pearl the Nursebot, a robot designed to interact with and guide people in assisted living facilities. Pearl is currently undergoing field trials in the Pittsburgh area.
• Guido, an intelligent walker that provides navigation assistance and collision avoidance for people who need a mobility aid and who also have impaired vision.
• CareMedia, a video-monitoring technology that can help to pinpoint physiological and behavioral changes among patients in skilled nursing facilities who suffer from Alzheimer's disease or dementia. The system captures video material from more than three-dozen cameras running continuously in the public spaces of these facilities and can automatically detect and catalog various movements, activities and behaviors.
• SMARTWheel, a wheelchair wheel that collects data as it moves, including the average force it takes to propel itself, frequency and length of each push on the handwheels, and the ease of propelling a given wheelchair. The SMARTWheel is commercially available from Three Rivers Out-Front.
• GameCycle, an exercise device that promotes physical fitness for people with lower-extremity impairment. The device consists of a videogame console interfaced with an arm cycle, which is used to control a racing game. The GameCycle is also commercially available from
