BrailleNote GPS
The BrailleNote GPS device is developed by Sendero Group, LLC, and Pulse Data International, now called HumanWare, in 2002. It is like a combination of a personal digital assistant, Map-quest software and a mechanical voice.
With a receiver about the size of a small cell phone, the BrailleNote GPS utilizes the GPS network to pinpoint a traveler’s position on earth and nearby points of interest. The BrailleNote receives radio signals from satellites to chart the location of users and direct them to their destination with spoken information from the speech synthesizer. The system uses satellites to triangulate the carrier’s position, much like a ship finding its location at sea.
Users can record points of interest such as local restaurants or any other location into the PDA’s database. Afterward, they can use keyboard commands on the unit’s keyboard to direct themselves to a specific point of interest.
