Blindness imposes the following limitations:

  • In the range and variety of experiences
  • In the ability to get about
  • In the control of the environment and the self in relation to it. (1948)

why gps
Why GPS????

“I feel like I'm "cheating" somehow, when I don't have to keep track of what street is what, where it's located, what direction I'm heading, etc... it frees my mind up to concentrate on other aspects of orientation...and then, listening to the GPS as I'm riding in a car, realizing the breadth of this world that is outside my car window I have heretofore never gotten to interact with…amazing,

simply amazing.” KM age 39

Landmarks/Waypoints
  • Street and Open Area Mapping
    • Know where you are
    • Multiple landmarks can be set at the same time/same spot.
    • Always set a landmark at the beginning of a route. Always set a landmark at the beginning of a route. Always…

sources of gps error
Sources of GPS Error
  • Signal slows as it passes through the atmosphere
  • Signal multipath occurs when the GPS signal is reflected off objects such as tall buildings or large rock surfaces before it reaches the receiver.
  • Number of satellites visible-buildings, terrain, electronic interference, or sometimes even dense foliage can block signal reception
  • Receiver clock errors- receiver's built-in clock is not as accurate as the atomic clocks on board the GPS satellites.

Craig L. Phillips, MS Ed. COMS

problem solving
Problem Solving
  • Always warm up the device.
  • Reset…
  • Routing Hiccups
    • No GPS coverage
    • Turn back
    • Off route
    • Silence

teaching considerations
Teaching Considerations
  • GPS usage demands solid fundamental O & M skills for the final +/- 50 feet.
    • Everything is relative.
    • Context clues/concepts must be practiced.
    • Organizational parameters
    • Time and distance
    • Solicitation of aid
    • Don’t tell…question.
