William Goh, a University of Florida senior in electrical and computer engineering, holds a personal digital assistant displaying a map in his right hand and a GPS device in his left hand on Wednesday, April 12, 2006. Goh and six other engineering students tailored the components to create a system that can track forest firefighters and special operations soldiers in remote, rugged terrain. The system also allows the firefighters or soldiers to communicate with each other or with remote commanders or observers via short text messages.
