Instead of stopping the run to pull out a phone, wait for the map to load, find where you are, and determine where you need to go, why not carry something that will automatically tell you where to go without interfering with your run? The GPS Running Watch is a personal GPS guidance device to help runners follow unfamiliar routes using an LCD display and haptic feedback. It guides the user along a path between preselected latitude/longitude waypoints by vibrating a small motor to indicate whether the waypoint is straight ahead, to the left, or to the right. You can stop worrying about losing your way home, and get back to enjoying your run.
Hi, I'm Kyle Kulis, and I'm Joel Heck, and this is our GPS runner's watch we built.
It uses a Ultimate GPS Breakout Adafruit GPS unit, and we use it for, hang on, I got started
where I messed up.
Just keep going.
Oh, okay.
Just for GPS location, for calculating your location within about 10 meters for when you're
running or logging waypoints.
Okay, and then there's a...
SD card.
SD card, which is, holds routes, and...
Right, and we can store currently up to 100 routes, but that can be expanded just by modifying
one parameter in the software.
But 100 routes, and you said there was 100 waypoints per route?
Yeah, 100 waypoints per route.
That's a lot.
Yeah, more than enough than anyone would ever need.
Okay, and now the, and there's a readout down here that's connected, which gives you...
So right now we're in the main menu.
You've got four buttons, left and right, back and select.
So from the main menu, you can select either navigation mode, the logger mode, or the statistics
mode.
So navigation mode allows you to select, apparently there's no routes on the card right now.
Is the card in?
It will also...
Yeah.
But, so you can do full navigation from here.
And then there's also a haptic feedback aspect to this too, right?
Yes, so underneath here, I can take it off in a second.
There's a small vibration motor, and there's another one on your right arm.
So it's just like that, and same thing on that.
And those vibrate when you're close to your next waypoint, so that it tells you the direction
to turn to go to the following waypoint.
I see, and so it starts a few dozen meters in front of the turn, and allows you to keep
your head up and watch traffic rather than watch a GPS screen.
You don't have to think about anything, you just feel the vibration of your arms, and
that tells you which direction to go into.
Okay.
And there's also a recording mode, right?
A logging mode?
Right, so the logging mode is basically a mode in which that shows you the current time
and your current location, and allows you to basically store points on a route that
you're creating yourself.
So let's say you're blazing a trail through the forest, and you want to log that particular
route.
So at each turn, you press the select button to add that point to the current route, and
then when you exit that mode, it'll save that into a new route file on the SD card.
And then the SD card has a FAT32 or a FAT16 file system, so you can read it on a PC.
Right, yeah, so you can add your own route files that you create using the Google Maps
route creator.
So we save our routes as text files, and you can go to this website, GPS Visualizer, upload
a text file, output as a Google Earth KML file, and then you can open it in Google Earth.
And this is just a route we did earlier.
This is not actually from the waypoint logging, but if you did do that, it would show up as
a red line connecting all of your waypoints, so you can see where you went.
Very nice.
Very nice, and the fixed time is pretty fast.
The initial fixed time is less than a couple of minutes, and the accuracy, you said, is
something like 10 meters?
It's pretty good, yes.
Which is good enough for running?
Yeah.
Right, okay.
Thank you.
