[IDEA/REQ] In-Call Lock Screen with Light and G-Sensors

Hi,
I recently bought a HTC Touch HD, and I think that the "shutdown-screen-when-you-answer-a-call" function of phones like Diamonds, Touch Pro and HD is the dumbest way to prevent accidental presses on the touch screen.
Our devices have a light sensor, that could be used to switch off the screen if the phone is near the ear (like the phone using an "i" word ) and keep it on when you answer with loudspeaker for example.
The "problem" with this function is that when you're already in a "no-light" environment, the screen lock function doesn't work.
To resolve this issue, I think we could use the G-Sensor. Indeed, if the place has no light, then, the phone cannot detect the proximity of a ear. But when you put the phone next to the ear, you hold it a the vertical...
To make it short, the app should do :
Do nothing in normal use.
When a call arrives :
- it monitors the ambient light
If there's light :
- when you answer the call, if there's light then no more (you stick the phone next to the ear), it switches off the screen and continue to monitor.
- while in call, if there's light again (you want to see some info on the screen for example), it switches on the screen and continue to monitor.
- and so on until you end the call
If there's no light :
- when you answer the call, but let it at the horizontal (you let it on the desk for example), it does nothing
- if you take the phone on the vertical position (you stick the phone next to the ear), it switches the screen off.
- if the phone, during a call, goes from vertical to horizontal of horizontal to vertical, the screen is switches on/of
- and so on until you end the call
Obviously, you could replace the "switch on/off screen" with "lock/unlock screen".
What do you think about ?
UPDATE :
After playing a bit with the HD, it appears that HTC DOES use the light sensor for turning the screen off during a call.
Let's do a test :
In a place with plenty light :
- put your mobile with the face up
- call a number (always face up) : the screen will not be switched off until the light sensor detects a loss of luminosity or a timeout set in the registry.
So, my conclusion is that HTC already use the light sensor to switch the screen off during a call, but they do it in an absurd way :
- they poll the sensor just to shut down the screen, not to switch it on.
- once the screen has been switched off, they do not longer poll at all.
Do you think it could be a way to "hack" their system to do what we want to do ?

no one has an opinion on this idea ? if there's nobody that want / have the time to develop a soft, I understand, but at least please, give me just your opinion

I agree with your idea for such an application. I must admit that I am very used to just pushing the power button when I answer a call (from Polaris use) to ensure I am not going into other programmes as I rub the phone against my ear. On the other hand I am trying to get used to the Touch HD's modern automatic method but I can't help not feeling relaxed that it has worked and keep trying to look at the screen in the corner of my eye to see if it did go off or not.
If it does not come now I am sure there will be such an app very soon just as you describe especially as all the latest models now have it.

i'd use the half of it that doesn't require the G-sensor as i don't have a diamond or HD...
but i'm certainly sick and tired of my ear operating my touch screen while i'm speaking.

I've written a prototype to do exactly what you are talking about although the one crucial part I am missing is the lock code. Every example or suggestion for locking the screen is very hacky and never feels like a good approach. If anyone has a good solution for locking the screen (especially in managed code) I would be happy to complete what I have started and release it with source so it could be improved upon.
So far, the best locking utility I have seen is PocketShield although I'm not sure what approach was used for locking in that case. It almost feels like a form that captures all windows events but I'm not sure exactly.

Maybe the simpliest way to "protect" the screen is to switch it off. I suppose it must be some API to do that ?
Concerning the "locking", I think the simpliest way is to put on focus an empty window (transparent if it can be ).
I'm really happy to know that you're working on an app like that

Thanks!

We need this app, how does the iphone acheive this?
I think the 'easiest' way to make this app would be to keep the phone doing what it does currently (put the phone on standby when answering a call) then have the light sensor take the phone out of standby when it receives light, (taking it away from your ear)?
Obviously if its dark then we would have to use the power butten as we currently do now or have the Gsensor do it with a twisting motion (vertical to horizontal).
If anyone has an idea how to program this i'm willing to help in any way, the current systems seems so crude on such tech devices!

There a program, that can help you. Not full, but it can switch off screen, using g-sensor. However its using not vertical aligment of the phone. There are using changing orientation of the phone to decide when phone near the ear.
http://forum.xda-developers.com/showpost.php?p=2622590&postcount=45

I have always wondered why our WM phones don't do what the iphone does...
For the SE Xperia X1, the light sensor is right near the earpiece (along with the little front facing camera), so it would go to virtually 100% darkness when near the ear. I would presume unless you are using the phone also in 100% darkness (which should be pretty rare I would guess) then it would work like the iphone.
I have also been quite annoyed by the fact that after a phonecall, sometimes I found i'm in a note taking program or weather program or something else. It just seems dumb, considering our phone HAVE these lightsensors?!

I think it's a fantastic idea to solve a VERY FRUSTRATING PROBLEM

I would rank myself this way:
Not a newbie who's just gotten a touchscreen phone and is now discovering the quirks when holding screen to ear,
and not a developer,
but a power-user. I have installed all sorts of XDA-developed features/enhancements for my phone.
But now I have 4 years experience -- starting with the T-Mobile MDA, and its successor, the T-Mobile WING. And despite all of the advancements expected in that time, STILL, I inadvertently end a call, or put it on hold accidentally, ALL THE TIME. Between that and trying to retrieve the phone from my pocket just to answer the damn ringing phone, I would say I have, on the average, a 20% success rate -- and 80% of the time the call is disrupted. And at least once a day my ohone, in my pocket, even when using s2u2, manages to REDIAL my latest conversation, so mcuh so that all my friends say "why don;t you get rid of that phone. It does all these whiz bang things but still can't reliably manage a basic phone call.
My most recent experiment was to call someone, then when they answered, press the s2U2 key to lock the phone screen. Only I came to find out from A_C that this is no good: S2u2 does not have recognition that you're ending the call, thus, since it's in lock-mode, the "END CALL" or Hang-Up hard key does not work.
So by all means, I would even pay for an app that once and for all handles the baseline problems of simply making a phone call. Thanks for making this request.

fireweed, have you contacted A_C, author of s2u2 ?
There may just be perfect synergy between the two of you. His "best of breed" screen-lock app is widely used -- and other developers, like supbro, for example, author of iDialer, have collaborated on small code-bits from A_C to solve some integration problems.
If for any reason you are unfamiliar with A_C, go to his website: www.ac-s2.com -- where his apps are explained, and all link back to XDA.
He's even managed to make the screen lock work, yet, have it selectively overridden when you insert headphone jack -- such that his s2p (slide to play) app opens and allows you to switch music tracks etc while otherwise the screen and buttons are all fully locked...

I think HTC does not only switch off the display but goes to standby (phone works independent if you didn't know yet). Your idea is a lot different in terms of programming.

I don't know if it goes to standby : when the screen is switched off during a call, a press on any button switch it on again. In the registry, the key controlling the timeout before the screen is shut off is named "LightSensorToScreenOff" so I think it is just switching off the screen...

Well if thats the case, its HALF of what the iphone does... it turns off the screen based on the light sensor going dark suddenly (next to ear) but then fails to turn the screen back on after you move the phone away from your ear...
Anyone know how to enable this?

Interested in having this feature too. Isn't it possible to have the G-Sensor determine when the phone is vertical and shut the screen and then when it is lying flat to turn the screen back on again. Believe that the Iphone does it this way, not with the light sensor.

Hmm... I never had my ear 'navigating' my phone during in-call before....
I never allowed the screen to touch my face anyway, and the speaker is facing the ear canal, when I receive or make calls...
But i do understand that s2u2 can do what you guys might need, it locks the screen during in call.

I think the Iphone has something called proximity sensor, which senses the distance from the ear to the phone, hence when the phone rest on the outer ear, the phone screen shut off.
Or am I wrong?

No, you're right. It uses an iR sensor to know if there's something near the phone.

[SOLVED] How to force HD2 to backlit buttons...

...when the screen is on? It's quite annoying to search the keys in dark.

i absolutely agree..........m also searching for such tweak.

intresting tweak !....i'm hope someone could solve !

what would be even better is to use the ambient sensor to turn on the backlight whenever the phone is picked up (using the accelerometer)

Yes this annoys me too is really hard to see the keys in the dark more so when the screen is lit up!

It's a good idea, but a little complicated...
Anything using motion just wouldn't be the best, since a lot of people put unit into a pocket, bag etc. Which is means the HD2 is usually moving as a result of walking etc. You might get away with sensing VERTICAL movement, but that is assuming the accelerometer can detect VERTICAL movement and it potentialy could be triggerd by normal movement in a pocket, bag etc. as well.
You might be able to use the proximity sensor with the accelerometer to do this. It wouldn't be perfect, but may work enough for most.
The simplest thing would be to enable the backlight to automaticaly stay 'on' when the device is activated (I don't need light to do this). Add to this a time feature that says only activate if after 6:00pm and before 6:00am. This means it wouldn't activate during daylight, unless you told it too. You would also need to add the feature to 'always' activate as some like to keep it simple or routinely visit dark places.

perhaps get it to light up when input is detected on the capacitive touch screen. that way it wouldn't get activated in a pocket or case. haven't a clue how to implement it but hey.

I really don't see an issue with wanting the keys lit when the screen's on. That sounds like a perfect solution to me. I think using sensors is overkill.

Interested in this tweak too...

Or use (light + proximity) sensor.

so no ideas then huh? i will have a root around through the registry settings to see if there is anything we can use for this..

i will have a root around the registry see if there is anything we can use

waaaaaaay too many "over complicated" solutions to this prob in this thread regarding using sensors etc ... you basically just need to stop the lights from sleeping while the phone is unlocked and on ! so if the screen back light is on the buttons should be too !!!!!!!!

yea thats what i was going to look for...
i.e. if screen is on.. turn the buttons on!!!

bump ! bump bump !

hahahah i was about to do the same

bump! it's a must !

bump from me too!
I am sure this could be done by a small registry change...but the mystery is as to which registry entry to look at!

Found a way to do this programmetically, I'll make a small test app for this tonight. Check back in like 8-9 hours, my boss won't like it if I do it during work time

What is it you've found? Is there a dll that can control the button lights?

[APP] Proximity Sensor for Screen Off v0.2

May be this tool will be usefull.
It switch off screen using proximity sensor detection.
Like alternative power button.
After proximity detected - screen switched off and proximity sensor don't used until screen will be switched on again manualy.
No screenshots
Second time running will unload program from memory, it can be used for switching on/off proximity lock feature.
All settings in registry, settings reloaded on each program run.
HKEY_CURRENT_USER\Software\Exidler\Hd2ProximityScreenOff
AfterCallReactivateSensor = dword:150 - time in ms when activate proximity sensor after call ended
SensorOffWhenProximity = dword:0 - time in ms when disabling proximity sensor on proximity detected. May be useful for disabling accident detection. This time proximity sensor is still active and if no porximity detected with this time - screen will be switched on automatically
ActiveOnlyIfLocked = dword:0 - Activate Proximity sensor only if Phone locked.
HKEY_CURRENT_USER\Software\Exidler\Hd2ProximityScreenOff\Exceptions
Create any named sub keys with values:
ClassName = string - name of windows class
WndTitle = string - title of window
ProcName = string - name of process
For exception windows proximity sensor will be disabled if this one window is active.
All criterias are optional. For example create only one value ProcName="Explorer.exe" for disabling proximity lock when Resco Explorer is active.
Proximity sensor activated only in portrait mode.
Change log
2010-01-29: v0.2
- full uninstallable cab
- add options: After Call Reactivate Sensor, Sensor Off When Proximity, Active Only If Phone Locked, Exception windows
- disbaling Proximity lock when landscape mode
2010-01-28: v0.1 Test version. Bugs possible.

Great something to get us started, did you make this yourself? Are you willing to put some time in to perfect it & create some options etc. if we bug test it?

How will this effect the screen turning on after a phonecall, i wan't the screen automatically turned on after a call without having to press a button.
Will this tweak allow default function in that case?

I don't know which options may be added.
I'm can't full control proximity sensor. It's only possible to enable proximity sensor, and htc drivers switching off screen by itself. The i'm disable proximity sensor again
But if it's will be possible to implement some features - i can try to do this.

Ok this is a good start, for me the following things need to be worked out for this to work good.
1. Only works when phone is upright, ie. Portrait. Reason being is if the screen goes off via Proximity in when holding the phone in landscape there will be allot of accidental activations, especially while playing games etc. It is much less likely that proximity will be detected when holding the phone upright.
2. Screen needs to come back on when proximity not detected, as to not cancel out the in call screen off feature.
Will keep thinking! Really hope you can work some magic here exidler!! Thanks

it will handle proximity sensor to default behavior after call. so i think (and shure) - screen will blink for short time (~200ms) and will be switched off by tool.

in call screen back on when no proximity
when not in call - it switch off. or you talking about switching on screen when not in call?
about landscape and portrait. it's make easy if screen orientation really changed (if not - polling g-sensor - is not a good idea for battery i'm think)

I just ment you don't want it to interfere with the in call actions the HD2 already has.
As you say g-sensor polling etc. no good for battery. I have a feeling this maybe flawed before we get started.

program know about call and not be interferace with HD2 proximity call actions.
Landscape alternative - Programs (windows) exceptions - when it's active - promity sensor may be disabled. (but this feature need more time for apply)

Just tested the app and maid an incomming call with an other phone, the screen will automaticly turn on after moving from my ear as should be.
Great app I must say!

My fear is when using apps like fpsece etc, the screen will keep going off. Need to put our heads together and brainstorm some ideas to prevent acidental proximity.
The landscape idea with g-sensor was the first thing that came to me but hopefully there will be a better idea. Maybe only when the phone is perfectly horizontal (i.e as it goes into a pocket) The problem is keeping the g-sensor active will drain battery....
Idea's peeps!!

Hmm no way of de-installing it. If I use the app and then push the on button and then try to remove the app via start/settings, after about 10 seconds the device freezes.
Even after trying to install the app again (wich usually workes to remove apps witch can't be completely removed via start/settings) the device freezes.
Taking battery out is only way to restart. App remaines on device though.
Noticed also that the app is flawed, trying to go with my right finger to the left top of the screen to push start makes the screen turn of and that simply sucks.

OK thanks, it's de-installed correctly. Maybe will use it in the future when it has matured a bit.

The programm should look on proximity-sensor, when i turn on my phone with the power-button.
--> if proximity detectet, screen should be staying off
--> if no proximity, phone should be wake up
Is this possible with your app? This would be a very great feature off our hd2! Perfect locking solution!

it's not possible until full hack of promitiy sensor.
i'm not have a fule of knowlendge fo arm assembler interpereting.
it' not difficlt for poples, how have knowledge of arm programs research.
but for me, i'm only can handle simple events
We are waiting for full promitiy API
so all of yours requests is impossimle.

Its a good start. Keep the project on.

perhaps a little bit easier to develop and to get various possibilities:
could you add 2 parameters to your app:
-activate
-deactivate
or so.
then it could be called also from other apps depend on its needs and states.
And also one scenario: It should only work if screen is locked(using notification).Then it's sure,that it should switch off because sensor detection
Keep up your great work.A really good idea,which can be very useful, if adaptable and a little configurable.
Thanx

An app to disable the automatic turno off of the screen?

Hello everybody, I know that perhaps I'm asking a [email protected]@t but, well, I try...I'd like to know if it exists an app for my HD2 that allow to override the global settings for the turn off of the screen. I explain: I want that when the phone is non connected to PC or power source the screen turns off after 1 minute so I've setted in this way the global settings, but I'd like that when a specific program is running (for example PocketPlayer) the illumination of the screen turns off but not the screen itself. Of course after the mentioned app closes the global settings start tu rules again ... Am I really ask too much or does it exist something like that?
Thanks and regards
Andrea

I think for your request you could use the Proximity Sensor for Screen Off http://forum.xda-developers.com/showthread.php?t=624206.
I use it, and when I have it connected to ActiveSync and I put my hand to the proximity sensor (next to the light sensor). The screen goes black, but ActiveSync remains running, so the device does not go in standby mode. I think that is what you need?

well, not actualy, I reliaze I have explained the question in a terrible way o ). What I need is an app that allows the luminosity of the screen to go off regulary but that doesn't make the screen turn off when some other specific applications are running.
But thanks for the information about Proxinity Sensor, it will become useful for me for another "thing"
Regards
Andrea

I'm also looking for something similar, for example when i use iGo8 navigation the screen will turn off if I have not touched the screen for a while (most likely I've overlooked something in the settings though :$)

I think I have exactly what are you looking for.
As long as 'Screen Alive' runs, it overrides system settings and as the name says screen is always on.
When you close 'Screen Alive' then system settings are coming back.
I have it working perfect on my Touch HD.

Tasker : Help needed to create profile

Hi,
I would like to use Tasker to control screen on/off times based on following conditions:
1) Keep screen on when reading/using mobile:
a)IF SCREEN IS ON: If handset is in vertical position (reading position), either in portrait or landscape depending on orientation set in android then screen should stay on. This would presume mobile is being used.
b) When handset is laid down on table then screen should turn off after 7 secs automatically or when screen is manually turned off.
note: It would be nice to have a window period of 10 secs after screen off wherein if the handset is picked up within that period, (after the initial 7 secs and before another 10 secs) then screen automatically turns on.
2) NOTIFICATIONS
If notifications are received, have a window period of 15-30 secs where if position of android is changed from desk horizontal to vertical then screen automatically comes on without the need to press power button.This presumes we picked up mobile to view the notification event.
Again first rule applies and screen stays on when reading and turns off auto or manually as per first rule
I have tried but not able to configure rules.
One conflict in mind:-
What if mobile is kept in trouser pocket and notifications are received? Here the gyro won't change as it will go from vertical to vertical position....how to deal with that? Also rule 2 should not auto trigger upon receiving notifications, sensing orientation is vertical when in trouser pocket.
Any help?
Thanks in advance

About the conflict, I think I saw that you can implement a profile that check if your face is in front of the tablet or not (like on S3).
As a personal comment, I would go all way to this aproach: check if you are in front of the camera and decide when to turn screen on.

Hi,
The problem with using the front camera is that it will cause battery drain. The camera would constantly have to keep checking for movement and this would definitely drain battery. I am more inclined to use the gyro for this.

I agree with you, but you can at least double the gyro with camera check. even if it will consume some battery, it will avoid other problems.
Or maybe you can also use the proximity sensor?
Another way I can think is to try and detect the shakes (combination of proximity and gyro). Considering the power of Tasker, I think it can be done.
If you manage to succeed, please let me know. I am also interested in something like this, I just never have the time to build such complex scenarios.
