I'm adding some sample text to see what happens...

For an updated project description, click on the following link for the Project Readiness Package. Visually impaired or blind (VI/B) individuals can have difficulty navigating through unfamiliar areas. Room numbers and locations are often indicated in Braille, but less than 10% of legally blind people in the US can read Braille. In order to address this problem, our team designed and created a navigation aid device for blind people walking in an unfamiliar building. RIT is home to a number of students with visual impairments, and many of these students are also deaf or hard of hearing. In order to meet the needs of the local population of potential end users of this device, the navigation does not rely on auditory cues, and it allows the user to continue to use a cane or guide dog. An integrated package that contains both the navigation and the input/feedback mechanism was created. The device designed can navigate a person from any point on the 2nd floor of the Gleason Building (09) to any other point on that floor. The complete navigation system is based on a series of RFID tags that indicate landmarks in the target area, and implements Dijkstra’s Routing Algorithm to determine the best path from a known starting point (based on local RFID tag identification) to a known end point (entered by the user). During 2010-11, a pair of teams (P11016, P11017) undertook initial proof-of-concept designs, which forms the foundation of our 2011-12 project. Below are links to their website and designs.
