Hi all,
Since the Touch Diamond has accelerometers in the X Y and Z space axis, is it not possible to try and create an Inertial Navigation System. For those who are not sure, it INS uses the accelerometers to assess the movement of the device. So long as the user states the start point and north orientation do you think it possible to do it and to create the software. If it is, then we could do without GPS, afterall, aircraft have used INS for a long time now (albiet theyalso used a gyro). It's not as accurate as GPS but it'll certainly work as a navigation device.
Any comments or help in doing this?
Some GPS systems use inertial navigation for better positioning when in tunners or low coverage areas.
The idea could be simple, a program that read the GPS data, mix them with the G-Sensor data and (why not!) with the TMC data recovered from the FM radio and publish them in a new virtual serial port.
But doing it is not so simple
I think its not dificul to trie i already post the idia in other forum, get the gps data, mix whit the acc, and start counting speed changes in forward . left/right and i think we can get a 600m bonus before black out.
600m whit simple formulas, complex ones give you much more.

The idea is simple yes - implementing such system is a lot more difficult than one could imagine though. It'll only be accurate for a short distance, before the errors become so large it's not feasible (due to double integration).

Hi people
A quick question regarding navigation software. I know Tomtom and Navigon are good for driving and for walking round towns and cities but is there any software for off-road walking ?
I love walking and climbing on the fells in the Lake District etc. and it would be handy to be able to fire up the GPS just to check that I am where I think I am
I use oziexplorer for geocaching, so it should be fine for your purpose.
I know that you can download maps for other parts of the world from their website, but I never have ... so I can't say how good they are.
That having been said there are utilities on the site to convert other map formats to be used by oziexplorer.
The site is http://www.oziexplorer.com/
I'm also using OziExplorer for now. Before I go walking / geocaching I scan a paper map and convert the map with the tools that you can get on that site.
If you are using a SirfStar III GPS make sure you turn off static navigation otherwise, if you are walking slower than 4km/h, your map won't update until you have walked about 50 meters.
memory map is my preference, uses OS maps of all kinds as well as allowing adding in your own if you set up the long/lat of a fixed point on it, although ive found it better just to get the electronic os version as the image is far superior, the ahard work is done for you and you can search via place names etc.
also the "3d" images and "fly throughs" make for fun evenings*
*(yes i am a mapping anorak )
Yep, memory map is superb
Always fun to download your recorded route back onto your PC and view it in 3D
GPS2Google
There´s a very nice tool called GPS2Google.
It just records your GPS- data, which you can upload to googleEarth later on.
Here you have 3D . way description.
Very geek an easy tool.
Its not fpr navigating, but you can use it while using your standard navigation-programm thru a virtual - comport-doubler.
Have a look here http://www.s-gps.com/

Try Tracky at www.trackthisout.com
I've been in talks with the author and he has now put in the British Grid co-ordinates and the OSGB36 Map datum which means you can use it with Ordnace Survey maps (a big plus in this country)
Tracks can be recorded, overlayed on a scanned in section map and analyzed later.
Great UI too. I am not affiliated
Thanks for the input everybody. I tried OziExplorer but had problems with memory (not got big storage installed so it ran out of memory). Tried Memory Map but found I had downloaded the OS version which doesnt allow you to calibrate your own maps ! Seems I must get a copy from the US site that doesnt have these restrictions.
Not tried Tracky yet, just about to download.
Thanks once again everyone, its nice to know there are people out there who get out of the car once in a while At least I have some idea of whats out there.
I know this has been hashed out a number of times, but I need to reassert the efforts of this forum on accessing the aGPS coordinates in many of our CDMA pocketpcs. The link below refers to a program for symbian UIQ phones that allows access to the aGPS for navigation.
http://www.wild-mobile.com/eng/viewproject.php?mid=b2d472166bbd3016587cfc659c792435
If this exists there MUST be a way to access the GPS coordinates on our phones. Ideally what we need is a way to create a softGPS that would output GPS coordinates to be used with 3rd party navigation software such as TomTom. I have heard that the output format for aGPS is different than with proper sat-based GPS units. Perhaps a program such as GPS Babel http://www.gpsbabel.org would assist with that. I will gladly ante up some money to anyone who can make this a reality (and I'm sure I'm not alone!) Thanks for reading this far down the page!

I have TomTom which is great. The GPS pins you down to within a few feet of where you are. Fantastic.
Assisted GPS (why they call it that beats me as it is definitely NOT GPS) has to determine where you are relative to cell sites and I'm not sure that it is going to provide an accurate enough fix to make is useful for navigating.
While there is a mysterious GPS section of the OMAP chip that runs an HTC wizard, I don't think there is definitive information as to whether it is actually used in these devices or not.
aGPS Hack on Tytan/Mogul
I, too, am eager to figure out how to get this to work. In theory, once we get access to the tower aGPS info, we could create a library that converts the tower format into standard GPS feed format and "fool" Google Maps, etc. into thinking it is accessing standard GPS feed data.
This would be immensely helpful, even if we can only get general location accuracy (+- 1 mile).
Hi everyone,
just want to know, for the VueFlo Function, is it very sensitive to slight and mild tilts? eg if you tilt the device slowly to the sides or up and down in IE, does the screen/page move?
If it is, I plan to make an app/software for it in the future
So interested in Athena but sadly, it's not available in Aussie yet.
its pretty sensitive, only need to tilt a few degree up down left or right. trick is when to turn it on, since all movements are relative to the orientation of the device when vueflow is activated.
i find it just a gimmick for web browsing
the most obvious application would b an arcade game navigating a ball around a maze or something
or a dodgy electronic attitude indicator for an aircraft

Ok. Thanks for that quick reply.
Electronic Attitude Indicator: That's the app I wanted to make.
The sensitivity can be adjusted to low or high and several points in between. Goto settings and VueFlo to adjust sensitivity.
You can also change it work to work in IE or Opera

Thanks!! That does the trick ... You Rock !!!!
So any more owners with comments on this feature? Anyone find it useful?
I find it very useful for random browsing of web pages and news pages.It is easy to turn on and off,and once you get used to it, it really works quite well.
Later.........

Yes, it's a nice little addon to the device. I use it when I am browsing long pages or am spending a lot of time online, etc.
Wish there was a way to customize it and allow it to interact with other applications. It would be ideal for there to be a settings area where you see a list of installed applications and a check box next to each. Then if you check the box next to Word for example, you could use it with that application. I wonder if it just emulates the directional keys and if so if this can be adapted as an alternate input method. Instead of using the joystick, just write a wrapper that will accept input from Vueflow.

That would be the ultimate solution for using SPB Insight RSS reader!!!
Any way to use VueFLO in all apps?
Obviously, this would be ideal for scrolling through emails/contacts etc.
Unfortunately, doesn't seem like anyone has managed to access the API's/runtimes for this yet---anyone want to give it a shot?
Guys,
I really think we should bring this one back to life, what with the iphone and all its spirit levels and labyrinth games
The simplicity of windows api structure is what makes pocket pc so versatile, lets take advantage!
And there isn’t a snowball’s chance in hell I’m going to sit back and watch my co-workers tell me how crap my phone is compared to their Iphone. I’m not in the game of letting a friend's spirit go uncrushed.
Y
The Vuoflo is no different in principle to the N95's accellerometer or the Iphone's auto rotate hardware. It could be used for anything involving d-pad movement (search for NOKMOTE or ROTATEME on Youtube and you'll see what I mean).
It seems that HTC have put a lot of effort into making this hardware un-tappable. Either that or developers aren't interested in developing for it. The possibilities are great though.
Hi, Does anyone know of a really good sports type gps tracker software?
I'm a keen cyclist and i'm sure there are lots of other outdoor types who would welcome a good, easy to use application with a full feature set. Samsung have just launched a phone with this in mind, Nokia already have one so it must be a growing market.
I had a Nokia N80 and downloaded Their Sports Tracker application and it was great. Just the stuff you needed - Timers, average speed, max/min speed, altitude, climing speed etc, even took out standing time (i think). You could upload to google maps if you wanted which was fine but not essential.
The Samsung mentioned earlier has music too geared to your activity.
I've tried lots of PPC apps like tracky and trackme and GPS tuner but the just dont seem to fit the bill, they are either too heavy and complicated and use too much memory or they are too simple with not enough usefull data.
I'm really suprised Windows mobile haven't got a better app for this - or maybe there is and I just don't know it yet.
Any Ideas - suggestions?
Roger
for you the same: dont douple post ! one question is enought, try search, this is a developers page.
This is the kind of application I wanted as well, so wrote one myself:

It looks I should have posted it into Development thread instead?
hi
i have installed tomtom 7 on my diamond and i have one problem.
Probably because of diamond's screen resolution(640x480) during navigation poi icon are too small....there is any way for fix it?can I just resize poi icon?
I have got the same problem, during driving you can't see the small icon properly, but secondly I am using the voices as well, so rather than just the beeping sound my camera database tells me what speed camera is ahead, so this solves the issue even better.
According to your advice I did try to edit and even created a new image of 32x32, 64x64, & 128x128, but none of that work, it just start to show a blank RED icon rather than "30" written on it, so I revert it back.
Regards
Sid

yes im using voices as well,but with ipod conected to the car's hifi its hard to hear anything else
I guess this problem should appear on every diamond,but around i havnt found any discussion about it.......
So,its a common bug or just for few lucky diamonder??
I have the same problem, the icons is too little
http://forum.xda-developers.com/showthread.php?t=432178
Icons gone !
I have no icons on a Western Europe map V725.1905
But i do have them on an Benelux Map V725.1883.
I don't know whats going on, i use TT7 V7.451 (9033).
Also my WE map loads and is very slow and Benelux is very quick.
Check it out, maybe i'm the only one.
Sorry guys one more clarification, are you using QVGA Tomtom version?
As I was using the QVGA version of "7.40.9028", but now I am using VGA "7.451.9033".
VGA has got normal resolution as in the QVGA everything was TINY.
Basically it is just one EXE file to overwrite the existing QVGA exe in the device, I don't know if the moderator will allow this, otherwise I could upload that.

Sid
I'm using the VGA Black 7.451.9033 on HTC Diamond, but the radar icons, poi, ecc. are too small and remain too small even by increasing the zoom

Like me!!!
My solution: I edit TomTom.exe to run it at low resolution mode. You'll see all menus fine... and the map and navigation screen at normal size (normal as QVGA equipment).
I spoke with TomTom's service and nobody has solution, while I can use TT7 at car and easily I can see the radar warnings.
From Xda developer tread...i don't remember where......:
I must say when I first got my Diamond it was TomTom that I was looking forward to putting on there for the real VGA 'experience' and at first glance I was very impressed... but then I started using it for navigation and, not least given I use it in 2D mode, soon found that everything was a tad too small! I wasn't so fussed about the POIs but it was the map scale overall - at arms length I could hardly see the map detail and really didn't need to see for 10 miles around - it wouldn't be so bad if it didn't zoom out so much.
So, here's how I sort of fixed it.... a kind of workaround which disables TomTom's awareness of it being VGA. The upshot of this is that everything becomes a reasonable scale however the drawback is that it's a waste of VGA and at first glance you might think 'oh my God that's awful - so blocky!' but I soon found that when actually using it in my car I really don't now notice. The blockiness is down to running at a non-native resolution - like all fixed-pixel screens you end up with unclean lines.
Grab yourself a copy of the freeware resource PC tool Resource Hacker, make a copy of the TomTom Navigator.exe file on the PPC, and open it up with the tool.
Now find the resource CEUX\HI_RES_AWARE\2057, right-click it and delete it. It will likely take the whole branch with it if it is the only entry in there. Now save the resulting file (I got an error at this point - dunno if it's Vista or what but it still seemed to work) and copy the file back to the PPC (note it makes a backup so make sure you get the right one!) - you might want to call it something different so you can then have a choice of VGA or non-VGA TomTom's to run.
And that's it... I'm sure when you first see it in action you'll think it's horrible... but in use I think it is fine and indeed for me makes it at least usable once more.
Lucausee i have use your solution, in effect solve the problem, tnx.
Excelent fix, well done and thanks.
