Accessible GPS Comparison by Mike May
Since, as the saying goes, "Not one size fits all", it is good that there
are 7 accessible GPS systems now available to blind and visually impaired
people. Sendero Group has established itself as the Rolls Royce of
accessible GPS since its first product release in 2000. Mike May, Charles
LaPierre, the Sendero team and its partners, have expanded Sendero GPS to
three platforms. It is no longer a question _if a blind person should have
GPS but a question of _which GPS to have.
A primary consideration is the type of user interface, both for input and
output. Is a keypad, Braille keyboard or QWERTY keyboard best. All the units
have speech output and some can also have a Braille display. A Braille
display increases the price considerably.
What other applications does the user want besides GPS and does he or she
already have an accessible PDA? If so, there is just one GPS for each of the
PDAs and that makes the decision simple both in terms of convenience and
The following bullets are meant to represent the distinguishing factors
between products. There are certainly many benefits of each of the products
not mentioned here. Other comparisons and product flyers are available to
learn about all the features. These are some distinguishing highlights.
Questions to ask yourself when evaluating the various accessible GPS
Self, what keyboard do I prefer or can I get used to?
1. The QWERTY options are: VoiceNote QT or BrailleNote QT
2. The Braille keyboard options are: Voice Sense, Braille Sense,
VoiceNote mPower BT, BrailleNote mPower BT and BrailleNote PK
Self, would a Braille display be valuable to me and can I afford the
The options for a Braille display are: BrailleNote BT or QT and Braille
Although an outboard display can be added to a mobile phone or Voice Sense,
this defeats the purpose of a small portable device and is not recommended.
Self, portability is important. What are the devices from smallest to
largest and what are their distinguishing features?
1. Mobile Geo on a Windows Smart phone with keypad interface, (powered by
Sendero GPS. 15 million points of interest, the smallest GPS device and
completely self contained. Since you have the phone anyway, adding the GPS
software adds no size, only cost to the equation. No monthly fees for the
GPS. Geo has the full power of Sendero's comprehensive software with
LookAround capabilities. It is the only GPS with vibration alerts in
addition to speech output.
2. Wayfinder Access on a mobile phone with keypad interface. This is also
small and self contained on a Symbian phone, mostly made by Nokia. The
software however is not nearly as full featured nor automatic as Geo and
there are fewer points of interest. Monthly data access fees apply. It has a
visual map display and fast route calculation.
3. Trekker Breeze is a self contained easy to use unit with 9 keys. It
does not provide automatic routing to commercial points of interest nor to
specific addresses. All routes must be recorded manually by walking or
driving the route and then retracing it. Under 2 million points of interest
in North America. Uses a Sirf 3 GPS receiver. 1.1 pounds.
4. Voice Sense with Sense Navigation (powered by Sendero GPS) has a
Braille style keyboard and speech output with a separate high sensitivity
GPS receiver. 15 million points of interest in North America. It weighs only
5. BrailleNote PK 1.1 pounds, has an 18 character Braille display and
speech output and a Braille style keyboard. It runs the comprehensive
Sendero GPS software and uses a separate high sensitivity GPS receiver. 15
million points of interest in North America. Definitely the smallest unit
having a Braille display.
6. Trekker 3.0 is a two piece 1.7 pound unit with a 33 key user
interface. Its software covers most GPS functions. It has less than 2
million points of interest in North America.
7. VoiceNote QT or BT with the comprehensive Sendero GPS software, maps
and 15 million points of interest in North America. Weighs 2.8 pounds.
8. Braille Sense with Sense Navigation (powered by Sendero GPS, 15
million points of interest), weighs 2.4 pounds. 32 cell Braille display.
9. BrailleNote mPower BT or QT running the comprehensive Sendero GPS
software with maps and 15 million points in North America. 32-cell Weighs
3.1 pounds. Comes with 18 or 32 cell displays.
StreetTalk VIP for the Pac Mate from Freedom Scientific is slated to be
available mid 2009.
LoadStone is a free GPS program for Symbian phones. It does not have street
maps, only points of interest but the price is right.
The price equation depends on whether or not you already have or can benefit
from an accessible PDA like the BrailleNote or Braille Sense products. Here
are the accessible GPS list prices not including the PDA starting with the
