Berthold Lowenfeld

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)

July 22, 2012


W h y G P S ? ? ? ?“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 July 22, 2012

Student Considerati ons

• Interest

• Perceived utility

• Maturity > Age

• Cognitive ability

• Dexterity

• Route concept

• Stamina

• Techiness is useful,

but not essential.July 22, 2012

Device Considerati ons

The difficulty or simplicity of learning how

to use a system must work for the

student first and the teacher second.

Devices

• Sendero Apex/BrailleNote

• Trekker Maestro and

Trekker

• Trekker Breeze

• Garmin Oregon 450

Begin at the Beginning…

• Start with the component parts

– Assemble/Disassemble

• Orient to the device

• Follow with the key describer mode

• GPS limits/parameters

• Movement versus static position

July 22, 2012


Begin at the Beginning…

• Start with the familiar

• Then walk, listen, and reference

– Learn the language

– Repeat the message

– What is the information…

– Where is it provided…

Mapping

Street Open Area

July 22, 2012


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…

July 22, 2012


Landmarks/Waypoints

• Pair with physical reference points

• Label noun first, then adjective

– “Smith High School, East Door…”

• Address entry results

July 22, 2012


Landmarks/Waypoints

• Nurture environmental literacy.• Fill in the gaps to develop the gestalt of

the area.• Set before and after hazards, headaches,

and irritations.• Practice renaming, deleting, and

unsetting as a destination.

July 22, 2012


Point of Interest = POI

• Point of Interest

• Preset on Maps

–TeleAtlas

–NAVTEQ

• Use POI rich environments to begin

Point of Interest = POI

Where is the “spot?”

Routi ng Reliability

• Self-created routes

• Landmarks and Waypoints

• POIs

• Address EntryJuly 22, 2012


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.

July 22, 2012


Problem Solving• Always warm up the device.

• Reset…• Routing Hiccups–No GPS coverage–Turn back–Off route–Silence

July 22, 2012


Teaching Considerati ons

• 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.

Teaching Considerati onsMuch better…

http://www.facebook.com/photo.php?pid=825895&id=1584588048



• Preview routes for “blackholes.”• Take a cheat sheet on lessons and use it.

• Use multiple SD cards.• Settings menu

• Earplugs and headphones are not recommended when traveling.

• Assume nothing and be open to learning.

July 22, 2012


Showing is better than telling…




• Let your student show you and others.• Inservice classmates, teachers, and

parents.• Encourage borrowing.• Get lost on lessons.• Motorized guidance
