Welcome orientation and
mobility trainers.
You’re there to help,
so we’re here to help you.
Trekker is a powerful and efficient tool that has
been developed from the ground up with
extensive input from our customers. Trekker
users continuously tell us they would rather not
be without it because it greatly increases their
self-confidence, orientation and independence.
This resource guide will help you to empower
your students with the skills they need to get the
most out of their Trekker.
What is GPS
Trekker uses state-of-the-art GPS and digital
map technology to help blind persons find their
way in urban and rural areas. Users can pinpoint
exactly where they are, learn about area
attractions, and find out how to get to specific
destinations. Trekker provides information to
help users get to where they want to go without
having to count steps or continually ask for
directions. It therefore allows users to
concentrate more on their own mobility and not
worry about getting lost or disoriented.
The Global Positioning System (GPS) is a
worldwide navigation system formed from a
constellation of 24 satellites orbiting the earth.
The idea behind GPS is to use satellites in space
as reference points for locations here on earth.
By measuring our distance from at least three
satellites, we can obtain our position anywhere
on earth.
Trekker has a GPS receiver that communicates
with the satellites through wireless connection
(Bluetooth) to the PDA (handheld computer).
The PDA has a map of the user’s area installed in
its memory card and is therefore able to tell
users where they are and what is around them.
How will this guide help me?
This guide is meant as a reference guide to help
you rapidly train users to get started with their
Trekker. To make it easier for you to access the
fundamental information you need, this
document contains easy-to-follow instructions
for basic Trekker functions and operations.

Description of functions
Explore your environment
With Trekker, you can explore your outdoor environment and let the system announce the information as
you pass by. You can use Trekker in any environment where you travel on foot or by vehicle. After powering
ON and establishing GPS coverage, Trekker will automatically find your position in the street and tell you
where you are. As you walk by, the system announces and describes upcoming intersections and Points of
Interest.
Where Am I?
When online with satellites, you can access information on your current position. Trekker will announce the
following information:
Route Status informs you whether you are currently on route (if one is activated)
The direction you are heading (North, South, East, West, South West etc.)
The current estimated address number and street name
The name of the nearest Point of interest (POI) with direction, and associated text note (if any).
The nearest intersection, in front of you.
The next instruction, if a route is activated.
Points of Interest
Trekker provides information about POI that have been marked in the map area. The system provides
powerful features to find and view commercially available information such as restaurants, hospitals, schools
and train stations. Users can also create their own landmarks by means of the POI recording feature.
POI can be used as the origin or destination of a route or as a starting point to browse an area prior to
visiting.
Create and follow a route
Trekker allows you to create a precise travel route by entering a starting point and a destination point. You
can then travel the route in real-time or explore it virtually with the browsing feature. As you travel, Trekker
will announce streets and intersections you come across and will provide turn-by-turn instructions to reach
your destination. The system can create route for pedestrian or motorized use.
Preview before going somewhere
Browsing allows you to virtually explore an area on the map using the Navigation buttons. You can also
browse a route previously created. This features allows you to learn a route or explore a remote area
without having to be there.

established, you can perform operations such as installing maps, exchanging POIs or updating your
Trekker version.
Trekker Map Manager
This software handles all map operations related to Trekker. A partnership with Active Sync is
required. There are many useful functions: Map installation, POI backup and exchange, route backup,
External database management, and more.

Glossary
Navigation modes
Trekker distinguishes three different situations coresponding to three navigation modes: Pedestrian, Free
and Motorized modes.
Pedestrian mode
Walking in areas where streets are available in the map is called Pedestrian mode. This is the default Trekker
navigation mode, providing GPS coverage and mapping functions associated with the installed regional map.
Free mode
Use Free mode to travel in unmapped areas such as parking lots, parks, campuses, or bodies of water.
Motorized mode
Use Motorized mode while traveling by car, bus or train. The main difference between Motorized and
Pedestrian modes is a reduction in the information verbosity level. The speed of motorized travel does not
allow the extent of spoken detail possible in Pedestrian Mode. So verbosity information is shorter to reduce
the length of the spoken message.
Points of Interest (POI)
POIs are landmarks that you may encounter in your travels. The system handles three different types of
Points of Interest:
Navteq POIs: commercially available information such as restaurants, hospitals, schools, train stations
included in the Navteq Maps. This information is included in the Navteq Maps.
Personal POIs: landmarks created by the user by means of the recording POI feature. Personal POIs can
be transferred to the main computer for backup purposes or shared with other users. Personal POIs are
organized in CSV (Comma-Separated Values) format.
External POIs: Trekker can handle POI information coming from third party sources. The system supports
any database in CSV format, provided they contain at least the GPS coordinates (longitude, latitude) and a
name, with a specific organization. Any database different from the Navteq or your Personal database is
considered as external and should be managed using the Map Manager tool in the External database page.
