I thing that everybody wants to have a g-sensor in their mobile . I have one idea . Is there any chance to develop a driver or software that can emulate g-sensor by rear or front camera ? Camera can catch "move" maybe in the same way like a g-sensor... Please think about it ...
I believe it was at least done on the Kaiser. The only issue I can see [apart from shoddy accuracy!] is, imagine the battery life being eaten!
Still, I'd like to see it, because it's the only thing I really want on my KS20
Function can be assigned to a hardware button, so it will start only if you want and then safe your battery
Ive asked about this a couple time and really got no where. I do know that the instinct uses this feature for scrolling web pages up and down

Then why not have the hardware button rotate the screen?
I see your point. I'd prefer to just have it running in the background. Drop the accuracy of it, and we could keep battery drain to a minimum perhaps.

but im sure that the great devlopers here could probably makes work better.
it makes me feel so bad not having a g-sensor.
today my friend was playing pocketgravity and he tried making things move by tilting my phone and it made me realize i need me a g-sensor.

Well, doesn't the game lack that feature or does it not need that implemented?
The thing is, there has to be a comprimise.
Get some serious accuracy, but to do that you'd need to sample a hell of a lot, thus killing battery life.
Or, sample less, less accuracy [but still good enough for screen rotation I'd wager], but less drain on your battery.

nope, someone just implemented it because it sounded like a good idea.
Will never work
Cameras have been used in the past for robotics and simply didnt work since they dont understand depth very well
What about combining the Camera and letting it work with the Infrared on the device? I know not all phones support both, but for the ones that do, its a step in the right direction.
External gsensor
Lets go back to the year 2000 where everything was external. remember the external camera on the sony ericssons? lets get an external gsensor
Maybe build in the battery like the fibration in the old Nokia 5100!
This thing must be possible.
I remember the game for Nokia phones, where you were controlling the ball in the maze. It was controlled by camera but it behaves like a g-sensor.
i dont know if this has been done but when you think about it many questions come to mind. first n foremost is depth. the softwares going to sense motion by motion in pictures from the cam. now if you have a white wall sufficiently lit and you shake your phone in front of it, hows a camera gonna judge motion from it? second, imagine a dot on the wall. now if ur close to it, theres gonna be alot more "motion" for the cam than if ur far away. i dont know the technicalities of the concept and if these problems will exist in a potential implementation, but, building on problems like these, i dont think its feasible or useful.
I think the theory behind it is fairly simple (and using the camera as a game input works as in Fishopolis http://rivia.net/Fishopolis.aspx Works on the Wizard). Take a pic A from camera at time x then take pic B from camera at time x + interval y then compare the two pics (get list of positions of same objects from both pix). If the objects in pic A are to the left of the same objects in pic B then you're moving right, left otherwise and a similar calc to determine up and down.
I think it is (actually know evidenced by the game previously mentioned) very doable and should take just as much battery power as using the video camera except for the storage since only a few images would need to be kept in memory at any one time and nothing needs to be stored on "disk".
Some matrix transformations and linear algerbra should do the trick... I'm sure someone has already done this in some form or another by now... Guess I'll see what I can dig up on the old internet.
why doesnt someone just work on internal accelerometers rather then trying to use the camera?
Thought you guys might want to check it out. Looks like it could be fun and it has good ratings...

Sweet... thanks! Look like a great time waster.
Looks like fun. Whats interesting is the on screen game control. They seem to have excellent accuracy with it. Its also apparently open source.

Trackball controls the direction, and onscreen controls are for jumping/flying and attack. No issues at all... very accurate so far.
You can also use the phones motion sensor to move the droid around, I find it a bit less fiddly than the trackball.
omg insanely addicting
Hmm.. seems a bit half finished to me. Trackball control is really clunky but the motion sensor speeds things up.
How do you get the music on the video? The one I download has merely a couple of beeps.
Great game. Very addictive. Controls are twitchy but not terrible. I love that it's open source too. There should be some great mods to this eventually.
omgah what a cool looking game. Downloading it right now!

Thanks for the responses, guys. I guess in hindsight it might have been good to leave out any negative things in such a positive conference.
But still, some mention would have been comforting.

I feel the same way halorin. It's natural to voice displeasure over something important missed in an update (I would have loved 360* rotation, colored trackball, fm radio, etc) but I know your happy about the update when it does occur and a great guy to have on the forum
All progress is still progress toward perfection, no matter how small.
Thing is, they were just demoing the OS, not device specific things like the N1's trackball & whether it has working FM etc.
Very valid point, Rusty.
Yup, each device will have their own seperate updates with device exclusive things.

That quote is from the highlights web page:
http://developer.android.com/sdk/android-2.2-highlights.html
The axis problem can never be fixed 100% because the hardware doesn't report enough info to do it for all cases, but currently it is pretty bad and I think better drivers/software could get it close. I believe that Cyanogen's ROMs have had some tweaks that have greatly improved its responsiveness for some time now so perhaps the Android engineers adopted similar fixes. It will hopefully get good enough over time that you'd have to know exactly how the sensors work and deliberately try to fool the drivers in order to get it confused.
I tested a nexus one on froyo today at google i/o, some things that were absent, colored track ball, touch screen wise they didn't have any multi touch analysis program installed, but just pinching around I don't detect any notable differences, so i'm guessing no to those 2 features on nexus, at least on their current build
I was also at I/O and while I did play with a few different Nexus Ones that were loaded with FroYo, I was unable to determine if any screen fixes were applied.
I asked a few times and each time I was politely told that they could not talk about anything that was not already made public (fair enough btw).
However, pinching and zooming on maps seemed to be smoother (not sure if it just my impression or some actual change) and it seemed to respond overall to my finger movements more smoothly.
Also, some games that I demoed on a few different Nexus Ones did employ finger gestures and those games functioned flawlessly from the touch perspective.
I am not sure that translates into any real fix or just my biases, but I am putting it out here for whatever it is worth.

Did you notice if there was 360 rotation? ie could you flip it from 12 to 3 O'Clock clockwise and get it to rotate to landscape when in a rotating app like Maps?

Dorick, by any chance have you noticed wifi-n connection?
I'm almost certain from the API improvement and UI modifications listed on the Android SDK site that we have a software fix for the crazy multitouch issue.
Having said that, it means the screen won't go crazy when the paths "swap". But, it's still limited to two touchpoints and not 10 like the 3000 series screen.
A fix is a fix though. =)
Personally if the have fixed up pinch zooming somewhat and made it smoother that will cover me 99% of the way as I use the device so that will be pretty much a fix assuming we actually see it in the official N1 rom.
So I'm writing this list in full understanding that it is still in development for the HD2. I just want to bring to the developers' attention about what I believe to be really desired features by many. And many of which I don't think will be hard development changes. If anyone else thinks of any, feel free to reply with your ideas and Ill update this post so developers don't have to search or "fetch" the for the ideas. Oh by the way, these features are ideally from the HD2 windows mobile side of things and I feel that if we can get these features on the Android side, it won't be hard for me to let go of WM. Hey, it's the truth.
LIST OF FEATURES:
Boost from 5mp to 8mp camera
Touch focusing on camera
Fixed led notifications [being worked on]
Auto backlight [being worked on]
audio routing through bluetooth?
Other things not directed towards developers:
CoPilot (Although Google Nav is doing it for me )
Office Mobile 2010 or close

Um we have a 5mp camera not a 8mp camera its a physical limit.
Ill have a play but I think we can already do touch focus and there are plenty of other camera apps out there.(upon a quick check i found auto focus but not touch to focus)
Led notifications "are" being worked on as we speak.
I believe the auto backlight works(kinda sorta) I believe I saw cotulla say it was working but the polling delay was high so you might not see a change right away. Not sure if they incorportated that yet.
I have not looked into these threads but I know that android has copilot.
and I know we have documents to go. There is a free version and a paid version.

I understand that we have a physical 5mp camera but why do we have that tweaking app for wm that tweaks it to 7/8mp?
There is a difference between touch and auto focus. Touch focus allows you to touch the screen and wherever you tap will come into focus. Huge difference when taking close-ups of an object.
Wonderful news about the led and backlight. Thanks for the update!
Only info i could find as far as the camera and android is 720p recording. It might be best to ask the camera question in the nexus1 forums. I am not sure the tweaks are legit.
A wise man once said your images will still look like crap no matter how many mp's you have if your image processor sucks.

quick wake up out of stand by
The "lazy" wakeup out of standby to one of the reasons why I switched back to WinMo (elegancia series).
There is a thread out there concerning this issue, but no solution.
the wake problem is being addressed. So there wont be a solution till the dev's figure it out. A lot have stated that using the evo kernal makes it a lot better but Ive seen higher than normal drainage.
Most Needed features
How about audio routing through bluetooth? Its 1 useful feature of Winmo that ive been unable to get on Android.

No we do not have a tweek for higher MP cameras.
The sensor in the camera is simply only able to register a photo size of 5mp!
Even with that tweek, the photo size is still 5megapixel. (i.e. 2580 by 2048 pixels in size). 5 megapixel will print at about 8 by 10 inch, do you really want a bigger print from your phone?!
Megapixels have nothing, at all to do with image quality (unless your printing large, even then they are sort of pointless!)
That tweek, as far as I know changed the DPI of the photos.
720p video would be nice though,lol
I wish I could listen FM radio through my bluetooth headset
Well personally for me the biggest issue is stable 3G/HSPDA performance. At the moment it is the single biggest limitation of Android on the HD2. All those other issues just pale into insignificance by comparison.
The next biggest is the poor GPS pickup speed. If these were sorted I'd be very happy.
maybe a louder volume hack... since meltus stopped updating for 2.1+
music speaker and speaker phone volume is too soft. The same song plays louder when i bluetooth to another phone.
Obviously, the Nexus 7 does not have a camera installed on its back side. Can anyone confirm if any barcode scanning apps would work? I know it would be awkward trying to scan a barcode with the front camera, but if anyone knows please reply!

How would you expect to line up the barcode without being able to look at the screen? I think scanning is out...
None of the scanning apps allow use of the front facing camera, so unless they decide to add support, they're not going to work.
and it's incredibly unlikely to be honest.
Unlikely I agree.
But think about the last time you bought groceries.
The scanner is like a big tablet, and you just pass the item in front of the camera.
I can see no technical reason why that model would not work.
oh i'm sure it would work with the front camera, but none of the apps support it as far as i know.
I'm sure you could request that the devs add support. up to them if they want to.
A high resolution, autofocus camera is needed to read most barcodes. The front camera might be able to handle QR codes.
Yeaa... I thought about this a few days after i posted this.... Isnt that what phones are for? because im not bringing my tablet around anyway.. just thought it would be a cool thing to have, stupid question by my

I don't think it is stupid. It may well be technologically unlikely. But no harm in asking the question. And if someone did this I'd be delighted. It would mean I could do my home shopping grocery order much quicker by just standing in my kitchen. I accept however that it is a long shot (very long).

Video calls. That appears to be the only real reason, for Skype and other VOIP systems. The resolution and fixed focus would bear that out, too. It's clearly not ment to be used as a regular camera, scanner, etc (though I'm sure someone will figure out how to do it...)
And that's fine with me, because the competition (Kindle Fire, Nook) don't have even that camera.
Scanning apps
There are a couple of scanning apps now for the Nexus 7 such as LearnPad Scanner (I can't post links yet)

Yes I am. It must be me if it is working for everyone else. Or maybe UK barcodes don't work on it. It says it only does one type in its help pages.

Hi, I'm an author of Barcode Scanner. It doesn't use the front camera since only rear cameras are treated as 'real' cameras by Android, and the API for using second cameras appeared later than the API leve the app supports (2.3), which makes it tricker.
We made a 'premium' version that does, among other things, support front-camera-only devices like the Nexus 7.
Search for "barcode scanner plus" on Google Play -- sorry I can't posts links yet.

Sean,
Would it be possible to have the app scan a bar-code using a phone and send the information via Bluetooth to the tablet? That way we have the best of both worlds. I would certianly pay for "Plus" to get this option!
Just found this... was looking for a way to scan QR codes for shipping labels into the Nexus 7. Learnscan works good, just takes a bit getting used to lining it up as it is backwards and reversed from what you are used to.
Works good enough in a lit room. Scanning stuff off the screen is easier.
Can you just put the tablet down on the table, bring the product to the camera, and look at the screen to position the barcode?
It seems very doable.
you can... in fact that is what I end up doing, but it is much harder than you think it might be. the app changes the camera view by rotating it, so you are working against where you think you should be moving to have you end up seeing....
If you had anything to drink, forget about it...
You have to actually try it to see what I mean... its like driving backwards except the camera view you are looking at is rotated 90 degrees.
the app btw is free, or least the one I tried.
