Alice, I think it can be broken down this way.
First, you have to understand that the car based systems and even the portable
systems are really designed for auto use. So all they really do is display a
map, announce some turn by turn and if you're lucky have the ability to work
with POI data of some form.
Our systems are very much more detailed and flexable. Also, because they
are primarily walking devices the mapping and level of details are much more
involved.
Next remember that not having vision really limits the interface
possibilities in some ways. Things that we do by entering in complex strings
can be represented to a user visually and the user can just tap that section of
the display. That being said many of the car systems still involve a lot of
poking and entering. My car system uses a combination of cursor keys and the
knobs so my driver does a fair bit of entering when using the GPS. Also,
another limitation of car systems is that once the car is rolling you can't
adjust your route or even work with the unit itself. (unless you rechip your
car and hack the electronics package like many of us do) The bottom line is to
get the power and flexability we have a more complex interface is required.
Add to that we can't see to use the devices it adds that much more challenge
and need for commands and text based control. Being sited though is definitely
an advantage in some key ways, productivity and speed being right at the top of
that list!

Is this also an issue with the "off the shelf" GPS systems that drivers use
in their cars? I also have the impression that we have to go through a lot more
steps of setting addresses and what mode and all that than those drivers do. Is
this true, or is it just easier and quicker for them because they use the touch
screen? Hmmm, guess I should ask one of the drivers, right? I've seen friends
use their gps in their cars, and it seems so uncomplicated and fast, whereas I
always feel like we are typing forever!

This seems to be an issue with all such GPS systems. This is one reason
why these systems are no replacement for your other orientation and mobility
skills.

Hi,
So I was walking around town last night trying to get used to using Sense
Nav. I was with a sited person, and noticed that while it identified the near
POIS correctly, it always said that they were to the left even though they were
in fact on the right side of the street, where I was walking. Also, there were
a couple of instances where I was literally right next to a place but I never
got a "look around poi" message indicating it was there. Do I need to ajust my
settings? Could I be wearing the receiver incorrectly? I am using the Hollux
M-1000 clipped to the shoulder strap of the VS/SyncBraille carrying case. I
normally hold it so the port used to charge it is facing downward and the light
that flashes is on the front. Sometimes it ends up being sideways when I'm
walking, but the light is still facing forward.
Thanks in advance.
Eric
