G-Sensor emulated by camera

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.

No it wouldn't, because as others have said the accuracy would be horrible.

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?

X1 - New Firmware

I am so proud of Sony Ericsson.
You know... Half of the company is from Sweden, where I live!!!
I just updated the phone to the new firmware. And I am almost shivering from proudness.
In ONLY FOUR MONTHS Sony Ericsson managed to make the Opera browser the default web browser on the phone. I can't believe how incredibly good they are!!!
I haven't notice anything else though, but oh my god... Isn't this more than enough to accomplish in ONLY FOUR MONTHS?
Anyone complaining on Sony Ericssson have to answer before me. I absolutely adore them. They are unbelievably good.
Anyone... Please don't tell me they managed to do anything else. I don't think I could take it. Making Opera the default browser almost made me faint. If you say something else was fixed too, I think I will die.

Cynic enough???
Here's what has changed:
Here are some things that have been noticed so far with this update.
The device now boots faster.
Faster menus - switching tabs in settings is quicker.
Programs launch quicker and file explorer is quick in loading folders.
The Vodafone ROM update (not sure if others have this) includes a couple of other additional trial games including Bubble Bash, Block Breaker Deluxe, and Tetris Mania.
Bluetooth Problem reported to be fixed. (I didn’t face any bluetooth problems with the old software and am not facing any now.)
Wi-Fi bug fixed.
Panel animation is a bit smoother but still laggy on switching from portrait to landscape and vice versa. Overall a faster panels experience.
Video playback has improved a lot! CP benchmark on a video resulted in 90-92% on the old ROM and is now increased to 98%.
Word prediction in most text-boxes.
Media Panel improvements including; music indexing is a lot faster, image scrolling is almost as smooth as it should be, changing tracks show information about the track at the bottom of the screen, and most importantly it now only shows pictures from the My Pictures and Camera folders on the main and internal storage – say goodbye to all those images from program files and windows showing up.
Camera improvements include faster focus lock and more stable focus. Preview is also smoother and introduces a new setting letting you define the frame rate to use for the video to shoot.
Furthermore, I think they updated the 3D drivers too. TouchFlo 3D is running way smooth - especially the Pictures and Media tabs! (flicking through pictures and music is quick and smooth) + Slide2Play is performing much better with this new updated ROM; quicker and smoother movement in landscape, switches album/song images correctly on song change, and so on.
http://xperiancer.blogspot.com/2009/01/xperia-software-update.html

initially when i just flashed the new firmware it was noticeably faster. boots faster and faster file system. used to take 8 secs to open /windows folder and after flash took just 2 secs!
but now after reinstalling my apps, the file system speed has decreased back to that of the old firmware. still boots faster tho.

i have reported that my x1 is very fast but i dont have new firmware installed yet..
i want to ask you how to install the new ROM? i got the new ROM from the pavel and download it in rapid share.

I see the framrate option. But I can't confirm it really works. As a matter of fact, I even don't know what to expect. I didn't get 30 fps before, and I'm sceptic I will get it now. But of course I may be wrong here.

Again, I can't tell the difference. I doubt Sony Ericsson had in mind that you should use TF3D. So the possbible improvements in using TF3D is irrelevelant to me. Maybe it's faster for other applications using 3D, but I haven't tried them yet and thus can't tell.
One of the most annoying bugs is not fixed.
That does not apply to you using english keyboard. But for me, using the swedish letters Å, Ä and Ö it does.
Those keys seems to be implemented after all "normal" keys. So where all other keys seems to get into a keyboard buffer when you type them, the special swedish characters are written immediately to the screen. That means when I write a swedish sentence that should look like "Jag ska försöka träffa dig innan mötet." instead looks lite "Jag skaö fröska ätrffa dig innaön mtet."
That is, in my opinion a HUGE bug, which they should have focused on before doing anything else.
Regards,
Michael

@Michael, did you bother to tell them about your HUGE bug?

Yes of course I did. October 24 I mailed them about this problem.
Should have been enough time for anyone with some competence to fix it.
EDIT:
As a matter of fact I've mailed SE 24-25 mails on different matters on the phone. Most of them might be specific to the operating system which SE has no control over, but for me as a customer that really doesn't matter. But the response I've got was just that, freely translated from swedish: "SE has no direct control over the issues since that is a Windows Mobile specific matter".
They even told me that about the Radio Panel.
Do you understand why I am a bit upset?
I like the phone even though it still has some issues, but I really can't stand Sony Ericssons ignorance.

Oh, and by the way...
Why should people even have to "notice" differences between firmwares?
We should be informed about the changes without having to guess what's fixed, and what's not.
It is our equipment, and it's our time and efforts we put in it to try to see if we get any improvments. We shouldn't have to do that. SE should give us information on what is done so we could decide for ourselves if the update might be needed or not.

wow..
yes it's annoying.
no you don't get better help when sending 25 emails in a few months.
welcome to the world of consumer electronics!
Why do you think that the iphone doesn't have a copy/paste function after the product has been on the market for 2+ years?
they don't give a **** .. you paid already
I think some ppl here have fixed some issues regarding swedish key press's.
not sure but try to search.. have seen some stuff come by.. but I don't need it so forgot where.
good luck

Just tried to update on the SEUS (sony ericsson) and it didn't work. Said It was already up to date. When I check my rom version it is NOT the new version

As for the biggest BUG you are facing, i can't say much about that - since it doesn't realy apply to me, as you too pointed out. But maybe you should try flashing on a non-Swedish ROM and see how that goes? For definitely all the points i highlighted are pretty much what i saw - with both the Vodafone as well as the Generic UK ROMs.
FYI - when i say that they probably updated the 3D drivers... i'm not just talking about TF3D (i use that as an example 'coz it was usually buggy before this firmware), but games are actually running as they should have done before. No glitches or problems with Atomic Cannon, Archibald's Adventures, and more games that faced usual lags or slowed down a bit in menus or something like that. Furthermore, Slide2Play is also working way better with this updated firmware.
the framerate option on the camera is great and actually works. The media panel has been improved a lot! The bluetooh and wifi issues have definitely been fixed... and the device startup time has been improved too, way quicker now.
55 Seconds?!?!?! - i barely got that with my old firmware! Maybe it is the Swedish ROM? Definitely try out the Generic UK or Vodafone UK ROM for a few days...
Best Regards.

I use the Swedish updated ROM, and I, as other swedes with updated phones I've talked to, don't feel any improvements with the new ROM. In fact, the phone seems to be slower when using SPB Mobile Shell: When clicking programs, it takes some time before the icons appear. Same time when sliding into the second page of programs. I didn't have this lag before updating...

Odd thing about Nexus One Multi-touch

I downloaded the visualizer app (the one with the 2 dots and not the square)
and yea if I begin on the left side of the screen then touch the right and move around the points hang a bit when they cross and will hardly ever switch (unless u do complex rotating action with both points but then the switch is periodic at best)
but if I begin on the right side of the screen, the points ALWAYS switch...always...
Interesting...does that mean it's a software issue?
I already KNOW this is the wrong section but I feel this is something that could benefit from the most viewed sub forum.
edit: starting from the right side, the points fix themselves when I do the same complex rotating action that sometimes causes point switch starting from the left. I'd record it if I had a camera, but yea.

none of the 163 (at the time of this posting) viewers have anything to say?
not even a "WRONG SECTION NOOB" (Despite my non noobishness) post?
sheesh.

wrong section, noob.

wrong section noob.

hahahhaha LOVE IT.
another interesting update: The previous results were on a Cyanogen Mod...
Using Modaco Desire Alpha 14 I get the EXACT opposite results...
Starting with a finger on the left side of the screen then the right side point switch is guaranteed...whereas starting with a finger on the right then the left point switch is non-existent.
I think it is entirely a software fault...anyone who knows anything have anything to say about it?

then again, the overall finicky-ness of it is probably just a flaw period...though I think it can be fixed with a software update due to the different behavior between ROMs.
seems to switch points at random actually...on the desire ROM especially.

still wrong section noob. haha.

It has been covered by pretty much all tech blogs on the 'net already.
Some think it is a hardware bug, and others think it's software. Who knows.
I don't think it will matter for most people, although I consider it a serious flaw if it is not possible to fix it with software.
And yeah, this might be the wrong section, but it could also turn into a dev issue. "wrong section, noob" was funny the first time.

yea that's why I put it here in the first place, I shoulda added [Think Tank] and then squeezed my statements there...def belongs in General though...any Mod please move there without any Snarky comments prior.

i 'll move it but with snarky comment : use edit button when you want to replay to yourself instead of creating two posts

I just tried that Multitouch Visible Test, and it does not always switch the dots. It is a little bit strange though, because it seems like the dots are just put on the wrong intersect of the red and blue lines. If it is a hardware malfunction it is a very weird one. Some kind of random mirror function.

Maybe its a problem with the app itself and nothing with phones.... comon now, I don't have a problem with multitouch and I think that app is horrible to determine a bad phone..
No offence people, but these issues everyone brings up on this phone isn't a issue at all... the 3g issue is network not phone, the wonky screen is from the wrap around effect, the multitouch issue is retarded.....
The only valid one imo is the dust...... everything else seems irrelevant

The multitouch issue is not app based, otherwise it'd be present on the Droid as well (where it isn't, infact Droid's multitouch is damn near flawless looking at that video and having owned one) Though it's not going to be an issue for anything I and many others current use the phone for (Browsing, Maps, Gallery, anything else that uses pinch to zoom) it will become an issue and may already be for multitouch games...From what I saw it seemed like it is likely software based due to the fact that on the Cyan ROM one thing happened in one order and on the Desire ROM same thing happened (and a bit more buggy) in another order.
But yea, about the 3G issue..I never had that either...in fact my 3G with my N1 is better than the 3G i had with my G1.

It may be just that There is different hardware/software in one vs the other.....
I still don't believe it will be a issue, I mean that app your sliding both fingers at the same time, and it only happens some of the time..... I don't believe there will be many games where your performing that kind of action, and even if so it don't happent all the time and may act completely differently in a game than it does in the app..... I mean, if it was a big deal we would notice it in the other pinch to zoom apps, I've tried on pinch to zoom to get it to do anything weird and it don't..... just saying, I don't think this video/app proves much....
Then again, who the hell am I.. lol I don't know shat like anyone....

temperbad there are a lot multitouch app in the market which state that Nexus One is not supported due to its multitouch misfunction..

Propably it is a hardware issue.

Try it in the browser. Pinch zoom out, then rotate your fingers in a circle and continue pinch zooming out. Instead of zooming out, it zooms in.

I too have absolutely 0 issues with pinch to zoom and rotating, getting my fingers really close together, etc. 0 issues whatsoever.
I'm on the Desire rom though.
Anyway, you have to remember this has absolutely NO importance whatsoever unless you play a lot of games.
If you don't, like me (I have a 360, so I couldn't care less), you'll never really have an issue with this.

Laggy input with multi touch visualizer

Hey guys, I tested the evo 4g multitouch input with the multitouch visualizer yesterday and found that though it does have much better tracking than the nexus one(no crossing and stuff) it does seem to have significant input lag, I do not have it on me to take a video, but download the multitouch visualizer and try moving around, the dot lags behind your finger significantly, anyone know if this is a hardware issue or just not tuned right?

Yea I'm noticing some lag too :/ bummer

I seriously hope this is a software/work in progress issue. I'd be severely disappointed to see HTC make such a mistake that they've avoided with past phones like the Incredible. I mean, why would they make the Evo's screen worse than the Incredible's?

This might be a deal killer for me. It is one of the reasons I've avoided Android up until now.

If there is not a software patch then I am sure FROYO will remove the problems.
I have a sneaking feeling that the camera, video and lag will be addressed at the update of Froyo 2.2

The Droid has a more responsive screen and no axis-crossing issues like the Nexus One.
Personally I wouldn't have noticed the Evo's input lag if I hadn't downloaded the Multitouch Visualization Test from the Market.

wow, thats retarded, it may be a deal breaker for me.

Possible to turn off Sense UI and test again?

I would love to see a comparison side by side with the Evo & the Incredible. All of the comparison I've seen are either the Evo vs. N1 or Incredible vs. N1. None of which the two are side by side. From the comparison I've seen with Evo vs. N1, the Evo is still far superior to the N1 as far as multitouch goes. In that case I'm not to worried.

deal breaker? no lag in the UI, but lag on one program that tests multi-touch and it's a deal breaker?
at least test out actual multitouch functions, if there is lag there than maybe a deal breaker, otherwise I fail to see how this is definitely an evo problem; maybe it is a problem of the program on the phone. I'll take real use over test program for my deal breaker.

As much as I'd like to believe otherwise, the same program running on my Droid is a bit more responsive.

But this is just a perceived problem running this test program, correct? I have read no negative issues regarding screen response in any of the reviews...

Whether or not people notice the lag while doing everyday tasks, that's a different problem. I already stated that I DON'T notice the lag doing other stuff.
But the multitouch visualization test running on both Droid and Evo shows that the Evo does indeed have some bit of input lag.

i wont call it a deal breaker but its definitely there.

+1
Is the Multi-Touch test app using OpenGL to render those dots? It may just be that the EVO is slower at rendering using the specific graphics API and nothing to do with the touch screen.
Overall it would appear that the current EVO is slightly slower than the Incredible (at least the benchmarks that I have seen on the web). I have also been reading that the firmware on the EVO is likely not the release version of software so for all we know these Google I/O and Advocate devices have been compiled in DEBUG / TEST code.

i tried this too, and it does appear to be true.
if you run the visualizer and try single-touch and double-touch response, and then go into google maps or a webpage on the browser, then try the same test, the response seems about the same. that's why i tend to believe the visualizer. i'll bet htc simply needs to optimize their touch input handling code to eliminate the lag
i also tried this killing every other running application besides the multi-touch visualizer and got the same result. it's the same whether running the htc sense launcher or the nexus one launcher. definitely not a deal breaker though

I have E-mail HTC about this and also give them my S/N of my EVO lets see what will they respond, I will let you guys know.
Thanks

Should be an interesting response, hopefully you don't get some auto-generated response based on keywords.
I agree with other posters, unless I see issues with actual use, I don't see this very specific application as anything near a deal-breaker. All other reports confirm that the UI experience is amazingly fast.
I'm not a developer, but my intuition says the observed lag compared to other devices has root in code that isn't optimized for this specific application.
Even if Froyo doesn't clear this up, it won't make a difference to me.

Its definitely not a deal breaker, but can be annoying for things like gaming and stuff.. on normal usage, you probably won't notice it.

It's most likely an input setting they put in for the phone for gesture recognition. I'm willing to bet is enough people complain about it they'll tweak it.

Nexus 4 pinch zoom delay

I just bought a Nexus 4, and am waiting for it to arrive. I just read about this dreaded pinch zoom delay (i.e. delay when zooming). Is this still an issue with the latest ROMs/kernels out there? I can see this causing me a lot of frustration if not fixed.
I've already searched, and the threads I've found are all either old or have not been completely answered.
Thanks!

I have no problem with zooming, and I bet that you won't too. Just wait for the phone, and don't read all the bad stuff. It won't do you any good. There are some rare bugs, but most users don't have them.

I don't have any delay in zooming issue either.

There is no zoom delay, its a dead zone. You have to move your fingers a certain amount before it detects it as a pinch to zoom or zoom out. I think it is intentional. Try doing it extremely slow, you'll see what I mean.

You've got it right. It's DEFINITELY present and those who don't see it either just innocently don't notice it or are denying it. Every single video review of the N4 I've seen has pointed out this issue (or feature, if you like) and I can very clearly see it on my device as well. OP, I'm not saying you should care about it (I don't even notice it any more) but it does exist.

I thought it was established long ago that the culprit was 'chrome' browser.. i just checked it in AOSP browser i cant seem to see any delay.

yeah its definitely there, but it is not lag, not even kind of, or delay or anything. it doesn't really bother me, i dont know why some people get so worked about it. what would happen if they cranked the dead zone down to zero... everyone would complain that its impossible to fine tune how close and far they are trying to zoom, or they keep zooming in and out on accident lol.

Yup, defiantly by design. If you start with your fingers already apart some, there is no delay at all.

Hate this deadzone!

the iphone don't have it so does my sister's xtreamer joyz(newman n2) with android 4.1.1 no one ever complained about hard fine tuning zoom!
i have this dreadfull deadzone too on my htc one x running aosp based 4.3(cm10.2) while on my sister's phone its a pleasent user experience.
note: THIS "LAG" IS NOT PRESENT IN FIREFOX!(no deadzone at all)
so definatly its an andorid gallery/gmail/browser(and any relying software like g+ whatsapp etc...) thingy.
this minimal distance deadzone is coming into notice when you are used to start zooming with fingers close together.
aka how zoom should be.
any way of trimming that distance out?
