Has anyone made a haptic touch plugin for wm6 devices?
Would love the phone to slightly vibrate when I use the touch keyboard.
I'm on a htc diamond btw.
I think it would be cool too, but I think one of the biggest problems is the time delay between hitting the key and feeling the vibration. I also wonder about the effect on battery life... anyways I would still like to try it!
You might want to do a search because I remember reading about something like this but think it was for the dialer.
I will post here if I find the thread.

Yea I am pretty certain one of the Iphone dialers is haptic or something...perhaps it's a dailer you have to pay for.
I have a couple kinda sorta solutions..
I'm at work so I don't have them here.. But I have one .cab that will vibrate when you press the number buttons on your dial screen, and it work's perfectly. And then I have an .exe that make's every screen tap vibrate, and it kinda sorta work's. I've looked for feedback programs for months, and have found nothing. The best thing i've determined which took me forever, is enabling screen tap sounds, and going into the registry and changing the default sound to vibrate instead.. I can also look up how to do this for you when I get home.. But really there's no good solution out there. On another note this would be almost considered tactile feedback.. Haptic feedback is crazy technology that deals with detecting the electrical current from your touch. That's why current PPC's are awful with this stuff, cause it doesn't have that technology, and most phones that say they do, don't, they just mimic it.

Tnx a lot walter, and thanks for explaining the difference between haptic and tactile
Posting a guide on changing the registry or giving me a link to the two programs mentioned over would be great.

uh, not quite sure what "haptic" technology you're talking about, but any feedback of mechanical vibration would definitely be considered "haptic feedback". From wikipeida: "Haptic technology refers to technology which interfaces the user via the sense of touch by applying forces, vibrations and/or motions to the user."
Also, to address concerns a little further up the thread: If implemented correctly, there is no perceptible delay between screen contact and vibration feedback. Me and a couple friends whipped up a little test application based on the WM6 SDK's application template, wherein if you tap anywhere in the application window, the vibration motor is toggled for ~50ms (this can be adjusted based on preference, but 50ms was a nice barely perceptible 'thud' with each tap). The feedback is, for all intents and purposes, instantaneous. Also, since the vibrator is only active for 50ms, you'd need to tap 20 times before you've drained the same battery as a 1 second text message alert, or 40 times for 2 seconds, and so on... really, I think the battery drain would be negligible. Anyway, proof of principle for using the vibration motor for haptic feedback is there, and the affect is quite nice, but we never got much further because of a lack of time and programming knowledge. By the way, if anyone has any information on how to hook into touch.dll (which would be the proper way of implementing a system-wide haptic response), I'd be very interested in hearing about it.
This sounds a very interesting idea! Not every program visually responds to touch when operated with finger, so sometimes I was just left wondering did I make the touch? Did the touch go through? Then one or two seconds later (yes my phone is that slow) something happens. This should help if not eliminate that problem.
Here is the cab for the haptic-esque dialpad if anyone was interested
i've noticed that when haptics is on, it tends to vibrate only every other press
such intensive vibration is probably bad for your phone

I know some people wanted to increase the keyboard backlight time. In case this hasnt been posted already, mad monkey has a cab for it:
http://www.dweiniger.com/tips/k-jam.shtml
No i have not seen this posted. tried on my qtek did not work - does it work on your device. i have seen a hack for the universal not wizard
cheers
nope this don't work on the T-Mobile MDA (US model)
Is it supposed to be a DWORD value? Anyone has gotten this to work?

You would think someone at HTC would know how to do it. Do any of those guys/girls post on this forum?
not that I've ever seen - not on any of the official retailer sites either. good luck
p.s. the question might not be 'how to do it' but 'can it be done'
yeah, I'm beginning to believe that the whole thing is completely implemented with hardware: a keypress starts a LED "On" timer. This is also why the kbd doesn't illuminate when it gets extended. Even though WM senses this and flips to landscape, it has no control over the backlight: It takes a keypress to start the timer circuit that illuminates the backlight you see.
bummer.

Working under the assumption that it is indeed in-hardware, there would've been nothing to prevent the engineers from making the magnetic switch enable the backlight, too
Working under the assumption that it's purely software, there should be nothing to prevent WM5 from doing this... other than that nobody has coded it to do so
Working under the assumption that it's hardcoded in the driver, somebody would have to hack the driver to extend the backlight; adding functionality to turn the backlight on would be a bit more difficult.

I'll give you "glass half full" on that one :wink:.
However.... the magnetic switch would be more difficult to implement than a simple key press which also resets a timer circuit. You'd have to tie that additional input into a circuit that could be hard-wired with the keyboard itself.
there's my "glass half empty" viewpoint.... I've just got a bad feeling on this one..... sorry.
I guess I'm going to have to take a closer look at some of the disassembled wizard pictures to make up my mind on this.
I sure hope a way is found to fix this as well as control those other blinking leds.....
well the point was, basically, there already -is- a magnetic switch. It's used to signal the OS that the keyboard has extended, and allow it to react on that; the chosen reaction being that the screen orientation is changed.
There would be nothing whatsoever stopping the engineers who actually put the thing together (not talking about somebody taking it apart and tinkering in there and whatnot) to have hooked that up to the backlight control /if/ that is in hardware %)
And if it's in software, then nothing would have technically stopped the software developers from making the keyboard slide-out trigger the backlight that way; assuming they already do as much on keypresses.
exactly. But the kbd does't light up when you extend it you see.... This behavior shoud be obvious
ok weird doesnt even put this into perspective ... i edited that value and softreset my phone. backlight timeout is still 5 seconds and now my bottom ( previously skinned) bar has gone back to default colours ... tried removing the value and resetting again had no effect either ... lovely hack this is now i can try and figure out why the hell this just happened ... running newest official qtek rom only for info
I think this is one of the largest downsides to this device. When I pull the keyboard out the lights should come on AND it should be longer then 5 seconds. It would also be nice if it had a light sensor (like on the SMT5600) to know if the light SHOULD come on or not.
If someone (or HTC) would fix this it would be awesome.
oh, they'll fix it - for their next device models The Universal already works that way, and you can tweak the backlight time. I'm sure by now they've gotten all the feedback they need to decide that that is better than the fixed behavior of the Wizard (not sure who at HTC ever figured that would be a good idea to begin with).
1 - Stylus camera. For those who does not like using the Dpad to take a shot and or for the upcoming touch HD using the stylus as camera button might work out.
2 - Stylus, light sensor, G-sensor together as a lock. I've seen keylocks with light sensor or the stylus. However, i'm sure many of us will agree the password lock on wm6 makes the device look like its from the 90s. Would it be possible to have all three combination of users own choice (some what like the G1's lock but with sensors instead of numbers or touch screen). Maybe its too fancy.
3 - Mute calls! Either in call or before picking up, would it be possible to make a trigger (flip phone 180 to left) to mute phone ring or hold call and flip the other way to undo. Or the other way around for left handed people. this way, you can flip to put the phone face down on table to mute or flip away from ear when driving to hold call.
4 - Finally, X1 is out!!!! Looks soo sexy. But seems soooo damn slow. But i can really care less about it. However, SE does have pretty damn good build in Apps and they have added them into the WM6 X1! Is there any chance if someone would want to use SE example camera's funtion/walkman function on a HTC device instead? In other words, is there any way to extract their build in apps to put them into other devices.
Sorry if bringing up so much. For all the pros here, there might be some stuff that sounds stupid but i wouldn't know cuz i have no clue on how to create my own ideas for testing. Would love to learn how to do so. Tips on how to start doing these shorts of things for a noob would be helpful!
O yea, one more thing, GAMES! needs to be improved for WM devices! as much as such smart phones were meant for business use, having more games wouldn't hurt. plus, g-sensor would help.
I was wondering if there's a app that allows the screen to turn off when you put the phone to you head? Then when you bring it out and in front of you, it turns back on. My Iphone did that and I loved that feature.
upping cause i'm intersted too
im believe this feature on the iphone is provided by a proximity sensor, you can probable do this with the light sensor but it would only work in the day time bc at night the screen would always be off...
not unless you use the gsensor too? i think if you work with the light sensor and the gsensor..you can get it to work. maybe have it only work when theres a active call.
This is an extremely good idea!
now if I was only a programmer
i'd love to see this feature on my diamond/blackstone too, i always have problems with the cursor jumping somewhere else when taking a note while in call...
theres already a thread about that:
http://forum.xda-developers.com/showthread.php?t=451456
sweet. thanks
I really love that fuction on iPhone as well. I found some program that can adjust the Light Sensor to dim the back light as you want. I never try it but surely not work in the dark. If any news on this issue, pls advise!!
I think the g-sensor is the answer, off course in combination with light sensor. If someone could make an app that would turn off the backlight during an active call AND when phone is in vertical position; this could resolve difficulties with light sensor.

There are a couple out there that attempt to solve the same problem the iPhone does.
One I know of is Touchlock Pro - http://forum.xda-developers.com/showthread.php?t=444215
It is free but it still has a little way to go before it is a polished solution
The other is PocketShield -- http://www.pocketshield.net/
It's not free but I found it so effective for the in-call problem as well as general locking/unlocking that it was worth paying for
I've also, as a developer by trade, played with the light sensor, g-sensor, and stylus sensor APIs and tried to create a basic proof of concept that solved just the in-call problem very well and found that without the approach taken by Pocketshield it just was not reliable enough for me.

All these programms are great software but are nowhere near the iphone solution... like i already said, the problem is e.g. that if you are on the phone and the person on the other end tells you a phonenumber you need to write down - the cursor always jumps to somewhere else as soon as you put your phone back to your ear (and then take it away again ofcourse to continue to notice the number).
ive messed with those apps before with no luch for what i was looking for. Simple app...JUST for incall and end call. light goesout..then comes back in. those other apps are pretty detaild

Very true, but unfortunately this hardware does not have the same sensor as the iPhone so you can only fake it so much.
I'd love to see this developed as well. But just wondering as some have mentioned using the gsensor; what if your laying down using the phone?
any developers out there. this would be awsome. make it simple. only works when the phone is in call. the gsensor sensing the phone from 0-45 degrees and only 0-5% light. seems sorta simple when u look at it like that.
hey everyone. My HTC Touch Pro came with this functionality out of the box. And i really don't like it at all. I think the difference to the iphone is that the screen does not turn back on until the power button is pressed.

My diamond does this already?
mine didnt. very weird.
For what it's worth, S2U2 v.1.42 has an option called "blank screen on call" which essentially disables the touch screen and makes it turn off when a call is connected (both sent and received). To get the screen to turn back on, simply press any hardware button. (Note though that pressing the END button while on a call will end the call as well as turning on the screen.)
I've found this feature to be VERY useful and figured it's as close as we're going to get for the time being .
Hi,
Is their a way that the call answer|home|Back|Call End keys can be highlighted in the dark with say a white light?
That would be so cool when using the phone in the dark!
I guess it really depends if there's some kind of light behind the buttons?

Yes it is so stupid that I think a ten year old child designed it. They are impossible to see in the dark and often I press the wrong one and are almost throwing the phone in the floor in anger
I suspose a skillful "Mod-er" could silkscreen some glow-in-the-dark paint on an adhesive layer (perhaps as simple as scotch tape) and adfix it to the front. Who knows might even be a market for this. I'd pay $4.95 US for it.

"But not $5.00. $5.00 is too much"
A lot better without any additional lights, imho.
I like reading ebooks in the dark with the phone, and experices with other phones have shown that leds etc are annoying.
solution number one would be a sw controlled led system that could let you decide on/off, intensity, color, animation motive, strobosystem connected to audio output, blinking and blinking speed, for each key independently...
maybe i just exaggerated but what the hell since it's all impossible as the leds aint there i don't see why i shouldnt

You could probably use available GPIO lines (if any are not used) to control the leds, but modding mobile devices without some kind of blueprints is next to impossible It's unlikely there's enough space inside the HD to house the leds and wiring required for such mod.
just hold your hand below your HD so the light of the screen reflects onto the buttons, simple enough imho
The buttons are overrated. I hardly ever use them. The only one I use is the very left buttin for Voice Command.
And I am able to find the button in complete darkness!!!!
I wish they would be gone in favor of a bigger screen.
HTC wanted to illuminate the hard buttons, but couldn't. The strategy behind the touch hd was to create the first device ever that will totally disallow its user to obtain any useful information whether a call has been missed while he was away from the phone. Moreover, part of the strategy was to *make sure* no matter how much the community will try to correct this situation, that they will stand no chance.
For this, HTC went with a tiny, faint, green led missed-call indicator at the side of the on/off button, and to make sure nobody will be able to program a solution, they had to let go the illuminated hard buttons (since otherwise the community could have programed it to behave like the Diamond, and so it would have been possible to know if you missed a call). It was a compromise for HTC, but the manager of the touch hd product recently was quoted saying that they feel satisfied with this compromise, because they feel that sacrificing hard button illumination was well worth it if the prize is to create the very first device that can be 100% inefficient at showing the missed calls you had while being away from the phone (and no less important: is 100% bulletproof against any attempt of the community to disable this cutting-edge feature).

Actually it's 99.99999999999999999999999% inefficient, but in this situation (where you'll have to miss several billion calls in order to notice one) I thought it was safe to round it up to 100%.
Surely the simple way forward here would be through the use of quantum technology.
We know that there are no lights behind the buttons, but that doesn't prevent the butons being illuminated, because in another parallel universe some HTC designer might have accidently designed a useful and practical version of the HD (of course, this is where my idea falls down, as it's impossible for any HTC designer to be so forward-thinking).
Anyway, as I'm sure we all know, you don't actually need an object to exist to have an effect in quantum physics - it only needs to exist in theory to effect the time/space continuum.
So if we could co-ordinate a mass simultaneous experiment, where we all throw our HDs up into the air, and let them all hit the ground at EXACTLY the same time, we should find that we will have easily removed the problem of non-illuminating buttons for all those partaking of this exercise.
A small side effect of this is that we will also remove the issue of poor video playback, poor call handling, crap Today screen ..........
"Anyway, as I'm sure we all know, you don't actually need an object to exist to have an effect in quantum physics - it only needs to exist in theory to effect the time/space continuum."
Boy this is scary, if your theory is right, we could all be subjects of an quantum physics experiment. What if the HD in fact doesn't exist att all!? have you concidered that? If your theory is right, it could just be a flicker in the time/space continuum. :O what the hell, as long as it's persistant I don't care.
To the more real issues. Honestly, do you guys really don't know where the answer, home, back and hangup-buttons are located?? I had not even thought of the fact that they aren't backlit. Most time I don't use them at all, but I'm pretty sure most user here in fact can point them out in pitch dark if they had to. But I must admit the lack of light underneath them is a little bit odd from a design point of view though.
For the missed call isue, isn't there a way to make the screen backlight flash with very short quite frequent flashes to indicate missed calls? For those who check the phone for missed calls every other minute this could be a good med against hart attack (or atleast blue fingertip from pressing the power-button a million times).

I really like those side effects, only problem is that we'll also lose warranty, so if in the distant future something bad will happen to our beloved touch hd, we will not have coverage...

Impossible !!!, you make it sound as easy as typing on a computer keyboard without looking at the keys... why do you lie to us my dear friend when we all know remembering the location of the 4 keys in the touch hd is orders of magnitude harder ?

Well... you have a point... but in the other hand your statement is pretty contradictory in itself. My computer (a macbook, I'll probably get my ass kicked for saying that) has no backlit keyboard and has something like 80 keys so it sounds pretty weard that it would be easer to learn the location of all of them. or have you written a program that alters the location of the 4 HD-keys so you honestly can say that it's impossible to learn?
Hello all. I am making an application request that may (or may not!) be possible. Ideas would be useful...
Basically, the idea is for a vibration feedback for screen taps. Obviously this is already available, however, it would be good if the vibration feedback could be localised to a particular space at which the screen is actually pressed... I.e if you press the top right corner of the screen, your finger/hand would feel as though it was actually pressing roughly that area. I have no idea if someone has already done this.
I actually think this is possible on the HTC HD because I note on the game Teeter, when you crash into a wall, say on the left of the screen, the vibration seems to be coming from the left of the phone. This probably means that there are at least 4 vibrators (if thats what they are called!), in the device... and further, it is possible to programmatically access them. If we knew how to do that, it should be possible to do some X/Y combination, especially to make a more precise vibration feedback for our HTC HD.
Ideas and thoughts would be useful.

I would solve this by having differenznt patterns
Wow, I'd never noticed that before.
Are you sure this works in each corner? My pudding pullin' numbed fingers can only feel top and bottom vibrations in Teeter. Are you sure it's in the corners?
Either way, sounds like an interesting concept.

Check the disassembly in the service manual: http://mikechannon.net/PDF Manuals/HTC_Blackstone_Service_Manual.pdf
At page 24, you see they take out the vibrator.
There is only one in the Touch HD, so the requested application in the OP is not possible.
There may well be one, but Teeter certainly feels "stereo".
There is a distinct left and right separation.

Yes, that's true. But they probably just reverse the direction the wheel turns to make it feel different.
I don't think you will ever be able to localize the sense of the vibration to the part of the screen where you touch it.
@Fire69 good point. Just what I do with the wife.
V
With the wife, you could use multiple vibrators!
Guys, you may be right. I am really very dissapointed with this finding. The teeter game totally feels as though it has multiple vibrators. I doubt spinning them the opposite direction changes the feel. It probably a psychological effect which relates to how we are holding our HTC at the time of vibration (!).
Really upsetting.
Also, is there a software that vibrates on pressure on any point on the screen with any app? There is an option to do screen tap sounds, but not vibrate. Help would be sweet.

Ofcourse! What else would we be talking about?
BTW, you have a spelling-error in your sig (Rapahel => Raphael)
I think the impression of "stereo" tactile feedback in teeter is coming from your brain, correlating tactile and visual input. You see the ball crashing into the right wall, feel the vibration and your brain makes "vibration coming from the right side" out of that. Knowing that you are tilting your phone to the right adds to that and is the reason why you also have the same impression when not looking at the screen (just tried it ). I don't see any possibility of localizing a vibrational feedback with just one vibrator. Multiple vibrators - different story, but I still doubt that could work, as you would a) need _lots_ of vibrators to generate a sufficiently precise interference pattern, b) need immense computing power to calculate the frequency/amplitude/phase of each vibrator to achieve that pattern and c) must be able to precisely drive all those vibrators with those frequency/amplitudes/phases. While I'm thinking about it, you could also just have a matrix of, say, 16x16 vibrators with absorbing layers in between. Hmmm...might be an interesting project to build something like that...
Indeed... I am sure I could have done something to stimulate precise tactility with 2 vibrators only. By controlling the duration of vibration for the X and the Y axis.
Hopefully HTC will include 2 vibrators with their devices in the future.
