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?

[Q] Flashlight-App for dual-LED (ultra-bright mode!)

Hi there...
I am searching for hours now...
I want a Flashlight-App that uses the "ultra bright" mode..
all apps I found only were "medium bright"...
if you ever used a Flashlight-App on HD2 on Windows-Mobile, you should know, what I am talking about.
Only App I found was nexus-one-torch.
I think it "takes photos" to make the dual-LEDs go maximum brightness, but the disadvantage is: it flickeres alot..
Anyone knows a Flashlight-App that uses maximum brightness of the dual-LED-Flash on the HD2 with Android?
Thank you!!
Greetings from Germany!

I like Tesla led. it seems pretty good...

But Tesla LED is not as bright as Windows-Mobile or "Nexus One Torch".
It does not utilize the maximum led-brightness. :/

Why would you need the Max LED flashlight?
Are you gonna setup a party xD!
I think that.. its useless.. the "one" (referred to the settings/drivers) we got now is awesome.. i can clearly see everything in my room when the lights are off.

Because the device is capable of such a brightness..
aaaand...
BECAUSE ITS COOL!

and you risk damaging your led lights...

Uhm.. NO? Windows Mobile runs the maximum brightness with the standart HTC-Flashlight-App.. so definately: no!
=> Still searching an app!

have anybody found app? i also searched it for ages ....

You risk destroying the LED's, they will burn out.
It doesn't matter what your own personal experiences are, they will break. Think of it like staring into a laser and not seeing instant visual disruption. It'll happen, just give it time and it'll mess things up.

Everything breaks eventually my friend. I admit it may shorten the leds life span but some might not care because they wont use their phone for years and years. I personally have been using high mode on my nexus one for over a year and its still going

If you need something brighter than tesla, wouldn't it make sense to just use a maglite? Phones are great for minor conveniences, but just like the cameras, if i wanted top quality photos, i'd buy a digital camera not try to squeeze quality out of an inferior cel phone cam. Same with the flashlight, great if u drop ur keys at night, not so much if you're trying to light up your whole backyard or something.
-HD2 Android-

i dont think the torch app really uses the brightest setting.
i think its a matter of being properly programmed/optimized for hd2.

You could try Mag Flashlight, it has two brightness levels, but I'm not sure if it can use dual LED

yeah i remember the stock Hd2 flashight was WAY brighter, it puts the ones on android to shame, i want it back!

Yes, I've downloaded all available flashlight apps on the android market for my htc hd2, and NONE of them have matched to the htc hd2's windows mobile version. That particular version had 3 settings, low medium and high. All of the android flashlight apps seem to match the MEDIUM setting that the windowsmobile version was able to output.
Can someone port or write an android app that's nearly identical to the stock htc hd2's flashlight app that had 3 settings, without the annoying 5 second demo animation at the beginning on how to use it? That third setting (high) was KILLER, and impressed all of my friends as to the htc hd2's dual led true potential!

Same here, anyone have found any program with full bright?

HERE IT IS! (well i think its it. IDK)
okay so i pulled this off my typhoon CM7. its the "Torch" app. it has a high brightness setting as well as a strobe feature. (i have my mini raves XD)
its in apk format.
put it in sdcard, use a file explorer to locate it and install it. it should work.
btw i forgot. if it works hit the thanks button have a good day.

Unfortunately, like everyone is saying even the one that you pulled from the typhoon (althought it says it is the highest possible setting) is not the brightest setting that WM was able to achieve. Anyone else still looking for this like me? If someone who knows what they are doing could do this, it would be awesome!
For those that don't understand why we want this, you haven't used the WM LED flashlight long enought. I actually have great stories that goes along with the brightness of HD2 flashlight in WM (from everyone envying me at concerts to saving a bunch of us in the middle of the woods after the sun went down in the middle of a hike that went wrong =P).

[Request] [Stronger HTC Flashlight like on WM]

Hey, ever since i moved from winmo to android, and now from android to wp7, i've always missed something from wm. That is, the flashlight. It seems the flashlights on both Android and WP7, don't use the full capacity of the leds. What i'm saying is that they're very, very weak compared to the WM one. I don't know if it could be possible to make an application that takes more advantage of the dual leds' capacity. If someone can, please do, cuz' that was one of the amazing things of the hd2.

Thank you, but:
It's the same as the one I've got, the purpose of this thread is seeing if anyone can make a flashlight that uses the full capacity of the leds, like on winmo, because, if you compare, winmo's flashlight is much much brighter.

hmmm i never experienced this.. Torch and TeslaLED both use the LED at an insane level of brightness. when you turn on super light in Torch it gets ridiculous! and i think the WP7 HTC Flashlight app from the HTC HUB is identical to the brightness of the WM6.5 one. i haven't done extensive testing, but i have never experienced any real differences. one click is still nice and illuminated where as the three clicks on and that sucker is bright

I don't like the way you have to click through all the levels of brightness to get back to off with the wp7 flashlight. It would be better if you could set which brightness, then just push once for on and push again for off... not having to push to turn on, then push 3 more times to get it off, going through every level of brightness. What were they thinking when they designed that app? Am I missing some way to operate it differently?

dunno old boy but i only get 1 and bit of the LEDs light up, the bottom one comes on but barely.
Camera flash works fine however

Yeah exactly, its as if it used only one of the leds instead of the two
On winmo it was SO bright it was blinding.
On Android its brighter than WP7 but less than winmo.

[Camera Glitch]

Hi guys, i dont know where to post this but here goes!!!!
Before the arrival of the Nand version of the android, there were many SD versions of the android that had a glitch with the camera focus, which the dev teams have ironed out. The problem was that when the camera was focused on a close object (video rec) and then the record was started, the camera will not auto adjust to other object but stay fixed on the focus point it was when you started. This was fixed with the button feature that was within the menus (auto focus on/off).
This may of been a problem for most users but was an excellent feature for the Mobile Directors (my university film crew). We decided that we will do all of our university film projects using my fantastic HD2 and this glitch feature played a vital role. I have been meaning to post our work here for a long time but never had the chance as it is our final majors. But i have uploaded 1 of the first video's we made long time ago using that glitch for the builds.
Now what i need help with is if those DEV SUPER TEAMS can look into this feature again and put it into the new builds so that we can carry on making amazing films with our HD2 if it is possible. The problem is that i cant find the old build i had and the new builds don't have this feature.
Before you say anything please look at the 1 min vid which we created with the focus problem (by focusing on foreground the background is blurred) that i am talking about and share your thoughts on the matter. (i will upload some more soon).
http://vimeo.com/22366901?ab
Filmed in black and white - please note the blurred focus scenes that were done using the glitch. FILMED ONLY USING HTC HD2 with very basic editing.

Which Rom are you using. I did a quick record test using the rom in my signature and it seems to focus fine when panning from a close object to infinity.

Duh,,,lol, well sorry about my misread. Well, I'm not sure where the issue was or fixed. But if you were using a sense rom or regular android, that would be a start as they use diff camera apk's.
Also, I think there were many settings in the media_profiles.xml in the root/system/etc folder that at least change the video size and maybe something that affects the focus.
If I now understand it correctly, what you really need is a "manual focus" control.
noellenchris

Good news! I tried some test video's using lgcamera (free in the Market) and if you tap on the screen it will focus on the close object and stay out of focus until you tap on the screen. Also I used Videocam illusion pro (not free) which I bought and tested the focus and it works like the LGcamera app. I think the Videocam illusion pro is better though, as it has some really cool effects you can also use.

Feature requests

Since the 2.3.3 update i've found SE have fixed the worst problems with the phone (particularly battery life). Hopefully in the 2.3.4 update we will get more improvements on top of just getting a new android version. So what features would you like to see SE work on in the xperia arc firmware? What doesnt work quite right?
Off the top of my head i'd like to see:
T9 dialling in the phone app
Ability to set image quality/jpeg compression level in the camera app
Improve the FM radio app (add the ability to manuall add, name & edit presets, and fix the bug where the radio fails after half an hour or so)
Some more folder graphics (e.g. travel, camera, android system, music, maps, etc)
Add the SE panorama app
Fix the manual ordering of apps after a phone restart
Implement digital zoom at 8MP just to stop people who dont understand how digital cameras work from moaning about it on forums
Anyone got any other suggestions?

Here are some more ideas:
http://talk.sonyericsson.com/message/73766
I agree with you on T9 dialing. That's really old school, so it should be in.
...aaaand +1 for the folder graphics. Nice someone else thinks of this, too. xD

Ability to set image quality/jpeg compression level in the camera app
+1 .

Heh, was planning to post a compliled list over there at some point, hence this topic. Wont do any good, i'm sure, but if you dont ask....

Well, SE seems to look into XDA as well (see KalleD's latest posts). And we might get a better list here anyway.

Digital zoom doesnt really do anything at 8MP - you get the same effect by cutting a small chunk out of the middle of an 8MP image and resizing it back to 8MP. Or by taking a 2MP image with digital zoom (which is valid on an 8MP sensor) and then resizing that back to 8MP (which doesnt achieve anything).
So SE kind of logically left out the non-feature from 8MP - I'm sure it made sense to the engineers at the time. However i've seen lots of complaints on various forums about how the camera zoom doesnt work at 8MP. It's difficult to explain to people that theyre wrong and SE is right because every other phone camera they've seen does digital zoom. SE should have left it in just to save themselves grief from customers who are now convinced that the camera in the arc is crap.

thank you daveybaby
I want these features to be included in the next update:
ability to take a screen shot without root.
include camera effects, like blur,viggentti (or something like it).
improve video quality and pic quality, a lot of noise in them.

smart search(smart dial) feature should be added in 2.3.4
menu re-ordering and wifi stability problem should be sort out by SE
and new update should be issued with statutory warning regarding unlocked bootloaders...

I think first thing SE should do is improve the speed in some basic applications. The speed improved a lot in Arc but still phone application and agenda is laggy sometimes.

Agreed with this. The other ideas sound good too.
One thing i'd personally like would be the ability to modify the dock color/transparency. I happen to like the SE launcher but the fixed color/transparency of the dock doesn't give me a lot of options for theming.

Ah, thanks, but it's not about having one.
There's already an airplane mode on/off in the bigger settings widget (don't know what it is called in English, sry ^^).
I simply like the design of the SE widgets so I would like to have this one, too. I already LOVE SE for re-designing the data connection widget with the latest update. It's awesome how they pay attention on something as small as that.
