Now there you go!  What we need here is a little rationality!  Jim

Hi all,
I'll do the side by side tomorrow.

Jim and Charles, very good points regarding the timing of the route creation. We don't need precision of a millionth of billionth of a second here. I created the route on the PK and it came out at 1 minute and 18 seconds. I hit the stop watch created the route then 
hit the stop watch off on the PK.

We will see what the VoiceSense gets.

n>For this even if the difference is a second it won't matter that
much

its not like we are clocking FLOPS or something.  A 60+ mile route
will have enough of a difference that a stopwatch will be more that
enough to determine how fast both calculate the same route.  I would
imagine that the Voice Sense having 100 MHz faster processor will
hands down beat the BrailleNote in route creation, my guess is there
will be probably a 5 to 10 second speed difference on the Voice Sense.

Actually, neither are a good solution.  Depending on the OS's (Did
someone say Windows CE?) you should run a benchmarking tool. Or,
maybe that's to complex, maybe if again it's a windows derivitive,
you could employ a port of the unix time command which literally
times the exact start and stop of a given process.  I'm not sure how
open these devices are though, my gut tells me not very but I've
been pleasantly surprised lately.  I'm rather thinking that the
results may be similar enough that human measurement might not
provide enough resolution.  At a minimum, precision is always a good
thing. (tm)

Sounds great, but to be fair, you should use a stopwatch to time
the route creation in both cases and see how long each unit
takes.  Counting beeps is probably not accurate as they may go
faster on the Voice Sense due to the faster processor.  Jim

Hi. On the Voice Sense I put in Sendero as the virtual position
and the Lighthouse as the destination. It showed that the
destination was 64.37 miles southwest from Sendero.

The Voice Sense plays progress tones, but I don't think they are
three seconds apart. I created the route using two slightly
methods. The first was using the micro hard drive CF card with the
whole West of the US loaded. The second test was with only the
California maps loaded in the flashdisk of the Voice Sense. In
both cases the result was the same. Creating a vehicle route took
57 beeps. The route had 364 waypoints. To be honest, this is
longer than what I would have thought. At least when I've created
many routes in Denver, Chicago, and Fort Wayne, 60 or so mile
routes do not seem to take as long, but I don't know if POIs or
map areas have something to do with this.

So, there is the Voice Sense side of things.

If we wwant to figure this out we can run a test. Let's say we
just have the maps for California loaded and create a route from
Sendero Group to the LightHouse and see what the
difference in speed is. Raul, I am not sure if there is some
progress tone on the Sense Nav. On the Sendero GPS, there is a
swoosh that occurs every 3
seconds to indicate some progress. Starting: Sendero Group
11188 Maple Lane Davis, CA Ending: LightHouse
214 Van ness Ave San Francisco, CA Could someone perform the
route calculation on the BrailleNote and someone on the
VoiceSense? We then can compare notes. It might be faster on the
VoiceSense as Alex suggested as there is more processing power
and RAM on the VoiceSense. There are many variables that aren't
accounted for, but this is just a general comparison. Kevin

Isn't the chip in the Braille Sense faster? Maybe someone from
sendero could
tell us if route calculation is noticeably faster.

Hello Eric. I'd be happy to comment on the Voice Sense side of things
although I'm not sure how much my comments will mean since I've only
used the Voice Sense and not the Braille note. The things i can comment 
on are mainly things which I've seen from reading other user
experiences, but none from me personally.

Hi,

I am curious whether anyone who has used both the BrailleNote GPS and
the Voice Sense GPS can comment on any differences between the two.
Thanks in advance.

Eric
