Global Positioning Systems and the Traveler with a Visual Impairment:"Who?" "What?" "Where?" "Why?" and "How?"

Craig L. Phillips

MS Ed. COMSSlide2

Kansas City Locations

2Slide3

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)

3Slide4

Ehresman’s Theory of Relativity

“You are only as

independent

as your relatives

Allowyou to be.” Paul Ehresman

First GPS satellite was launched in 1978

Built to last about 10 years

Weigh approximately 2,000 pounds

17 feet across with solar panels

Positioning System 101Slide9

Satellites orbit 12,000 miles above Earth24 satellites constantly moving

Two complete orbits in less than 24 hours

Travelling at speeds of roughly 7,000 miles an hour

Global Positioning System 101Slide12

Signals travel by line of sight

Can go through clouds, glass, and plastic

Cannot

go through most solid objects such as buildings and mountains

Three (3) satellites to calculate a 2D position (latitude and longitude)and track movement

Four (4) or more satellites to calculate

a 3D position (latitude, longitude, and altitude)

15Techiness is

useful, but not essentialSlide16

Ten Essential FeaturesTurn by turn, block by block route directions

Announces position in space and direction of travel before and after each route segment

Upcoming intersection type and roundabouts automatically announced

16Slide17

Ten Essential FeaturesPedestrian routes created for distance

Motorized routes created for time

Built in pedometer

Off route detection and route correction within a city block

17Slide18

Ten Essential FeaturesWhat’s Around

*near < 500 feet *far > 500 feet

Automatically announces POIs, landmarks, and POIs in pedestrian mode

Automatically announces landmarks and waypoints in motorized mode

Device Considerations

“The difficulty or simplicity of learning how to use a system must work for the student first and the teacher second.” Mike May

It’s not about you… It’s not about you…

It’s not about you…

Four Stages of Learning

Unconsciously Incompetent

Consciously Incompetent

Consciously Competent

Unconsciously Competent31Slide32

Begin at the Beginning…Start with the component parts

Assemble/Disassemble

Orient to the device

Use the key describer mode

Talk About GPS limits/parametersMovement versus static position32Slide33

Begin at the Beginning…

Start with the familiar

Then walk, listen, and reference

Learn the language

Repeat the messageWhat is the information?Where is it provided?33Slide34

38Slide39

Landmarks/Waypoints

User created

Multiple landmarks can be set at the same time/same spot.

Know where you are

Always set a landmark at the beginning of any journey. Always….

39Slide40

Landmarks/WaypointsPair with

physical reference points

Label noun first, then adjective

“Smith High School, east door”

“Fraser Hall, front stairs”Address entry results

40Slide41

Landmarks/WaypointsNurture environmental literacy.

Develop the gestalt of the area.

Set waypoints before and after hazards, headaches, and irritations.

Practice renaming, deleting, and unsetting as a destination.

Sources of GPS Error

Signal slows as it passes through the atmosphere

Number of satellites visible, terrain, electronic interference, or sometimes even dense foliage can block signal reception

47Slide48

Sources of GPS ErrorSignal multipath occurs when the GPS signal is reflected off objects such as tall buildings or large rock surfaces before it reaches the receiver,

i

. e. “the Canyon Effect.”

48Slide49

Problem SolvingAlways warm up the device.

Use the Resets

Routing Hiccups

“No GPS coverage”“Turn back”“Off route”

Wisdom“I have found over the years that the teaching of

Orientation and Mobility is

an art of accepting approximations

.”

Dr. William Penrod50Slide51

Teaching ConsiderationsGPS usage

demands

solid fundamental

O & M skills for the final +/- 50 feet.

Everything is relative. Context clues/concepts must be practiced.Understand organizational parameters

51Slide52

Teaching Considerations

Time and distance

Solicitation of aid

Don’t tell…question.

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

it.52Slide53

Teaching ConsiderationsUse multiple SD cards.

Practice

with the settings menu

Earplugs and headphones are not

recommended when traveling.Learn to think without vision to effectively teach those without vision.53Slide54

Showing is far better than telling…

it’s all about doing.

Teaching Considerations

54Slide55

Teaching Considerations

Encourage borrowing.

Get lost on lessons.

Teach motorized guidance.

Have your student show you not tell you.In-service parents, relatives, teachers, and classmates.55Slide56

she sets landmarks, creates and complete routes, enters addresses, and directs drivers.

The GPS Continuum

“Outer space.” Age 5

“Mommy, we need to turn here” Age 7

“Directing a cab driver to my destination gave me control.” Adult

60Slide61

FYI…

“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.”
