touchscreens come in verious flavours
the ones our pda have with the coating
wacomm active digitizers which only respond to the pen mostly used on tablet pc's in the high price range
hp have a sensor detect system for their kitcten pc which also seem to work fine and support multitouch like iphone
read about a new tech where the screen itself is a sort of webcam so it can detect touch's and respond to them in kind
said the screen itself could even be used as a scanner
wonder what tech will show it's face in the htc phones to come ...
p.s. wacomm is good for drawing fake rembrandts but poor if you like to click by using headbuts
I don't have the link for it, but I saw this clip on another PPC forum where describing a "two sided" touch screen.
Basically the idea is this: when you use your fingers on a touchscreen you obscure part of the data. So they use a camera on the back of the device plus movement recognition software to see where your fingers are (if you were holding your PPC like a game controller with only thumbs in front of it) and project a shadow of your fingers on the screen.
As if the screen was "see-through".
I tricked my friend into thinking that the mousepad on my laptop was also a scale. Would be pretty cool if the screen on a ppc could weigh small measurements. That way I'd never get chinced again when picking up herb

HI all, I dont know if anyone has this situation...
Everytime I press on the screen, the screen generates a bit like a water wave and the situation is just like pressing on a LCD monitor.
My old M3100 doesnt have this situation...how about u guyz? do you have water wave when u press on your tytn ii?
thanks
Hmmm, maybe it's because you ARE pressing on a LCD screen... I never press hard enough to see it, but I'm sure it would.
Yea seriously, how hard are you pressing? I don't think you need to be pressing nearly as hard as you are. I can see the ripple if I press really hard, but that much force isn't necessary for your taps to be recognized (and its probably not good for the screen).
I was going to post about this earlier. I too have this problem. I owned an 8525 before, and it never rippled unless you were exerting massive force.
My current Tilt you barley tap it (like say, you are touching the dial pad to call someone) and it has two large ripples happening.
Is this normal for everyone? I called ATT about this, and they just sent me a new one. I just haven't opened the new one yet.
I found this out cos I am using my finger to use the Touchflo...I didnt apply a very aggressive pressure on it...I even see the ripple when I slide the keyboard out. Is it normal?
no its not normal if you are pressing softly and having wave like that. Please do the warranty exchange.

AT&T just sends you a new phone without even asking for the old one back?
I've seen the small ripple when sliding the screen out. Maybe it's the magnetic switch..who knows. Doesn't happen all the time.
I have uploaded a video on youtube about my screen problem
I only pressed it gently on the screen.
http://youtube.com/watch?v=b03x2VldcmI
Do you guyz have this problem?
Anyone? it seems I am the only one to have this problem...
Hi
It depends on the LCD panel, there are different types of panel, some will ripple when pressed or distorted even very slightly others don't.
The problem with asking others is there are at least two different types of LCD panel used in the Kaiser. One we know to be transreflective that works in direct sunlight and looks kind of green rather than black when off, and one that's not transreflective that is black when off and doesn't work too well in direct sunlight. These panels may well be using different LCD technologies in other ways meaning not everyone will see the same as you.
Mine isn't transreflective and doesn't do this, so perhaps you have a transreflective type that also ripples under pressure. It isn't a fault with the LCD display, rather HTC sourcing whatever types of panel they can get at the time for the cheapest price. You wouldn't normally use a panel that ripples when pressed on a touch screen for obvious reasons, but HTC have. Maybe it was a shortage in supply and there are not many that use this type?
Regards
Phil
It shouldn't happen. Exchange it.

They charge you for the second one and then refund it when they receive the old one.

They sent my second one out to me at no charge. They forgot to include the shipping labels...again... so they will probably just end up letting me keep the device.
Anyhow, my Tilt ripples exactly in the same place that the video showed, and in the same way.

Is the ripple gone for your second one?
Where is your Tilt made?
What's the model code under the battery (ie. KAIS300)?

We don't know this at all, there apparently are at least two screen types but neither was transreflective, both blew out in direct sun.
The ripple is a function of the thickness of the glass screen. Since liquid crystal displays work by electrostatic twisting of a liquid suspension of quartz crystals thereby bending the light to allow it to pass thru polarizing filters, any physical movement of this suspension will also cause visible light artifacts. So if the front panel is lighter weight material, it will show more "ripples" if pressed firmly.

There are different technologies used in the production of LCD panels and how the glass is spaced to give room to create the pockets for the liquid crystal.
Some displays "water" when you press them, others don't, it depends on what the type of LCD display it is. My monitor at work can be pressed and nothing happens, my one at home is the opposite. It's not hard to find this explained on the internet.
The Kaiser is using different types of display using different technologies. Typically for touch screen applications (unless the display as a touch glass front) would not be of the type to ripple when pressed for the reason it will be pressed and flexed, but obviously HTC is supplying anything they can get.

there is a new HTC touch phone with the ability of fingerprint ID sensor for more protection ....... can any one extract this cab from it ...... making it work on tytn II ???????
no way, i think that the tytn2 touchscreen is not that sensitive and precise for that kind of functions...
i'm maybe wrong....
You are quite right. Plus, the touchscreen on our phone can only sense one point at a time. If you push down in multiple points, the touchscreen gets confused and returns a single point, usually exactly between the two points you are pressing. So, if you press down with your thumb, it will just return the single point at the center of your thumb. The phones that have fingerprint security also have special fingerprint sensors built into the phone, separate from the screen. They are the same type of sensor used in laptops or desktops with fingerprint sensors.
good idea
reaaly we want something like that in our kaiser's loool i hope so the developers Don't sleep for us and try to create a program like that maybe we can use the camera instead of the screen or the fingerprint sensor or by i eyes i think i saw something like that with the camera and eyes print lool in iphone i think i do not remember where i saw this before
Isn't possible. Hold any touch screen just right under light, and you can see the light dots on the touch panel. It's a matrix, and it responds to an X & Y coordinate. It would take something like a swipe device for fingerprints. I think MS has one that does that, for the PC.
i dont belief this. came onnn man that is unposubul maybe camera but camera need to me very sensetif min. 5-6m.pix and when is lock camera will lock is well may be same how way around keep the camera unlock but thad way around is not going to be safe to so yes this unposubul on tytn 2. aaaaaaa i thing i found solution lets go to htc and ask them to make new pda and make shour to put finger scan buld in is well.
by the way any one have same information about new htc pda yet?
I think the same guy wrote this.. http://freewareppc.com/misc/xray.shtml
You can download S2U2 and modify the Slide to Unlock text to read Biometric Reader. At least it looks cool when you slide your finger and it unlocks the screen. Just don't let your friends try with their finger. : )
my 2c
maybe someone with experience on face recognition could use the image from the frontal camera and process it to see if it is the "mug" of the owner.. just an idea ..
When I first ordered my tilt, immediately after I had the fear that the screen would be like most other PDA screens - they get "depressed" when you push them in, they feel plasticy, and they go "weird" when you press on them even slightly hard. To my dismay, the phone WAS like this! A perfect example of a good screen would be the fuze, iPhone, and the at&t quickfire. The screens feel solid, and glassy. Why doesn't the Kaiser have this?
Good Question. Id suggest writing HTC Please let us know what they say

Simple. Don't do that. There's zero problem with the Tilt screen otherwise. Light touches, moderate touches, swipes, finger, stylus, all are fine. Of course this is referring to the digitizer. What you're referring to could be a mix of both I suppose.
I don't *poke* LCDs, it's just a bad idea.

Digitizers like the one used on the Kaiser work by having a soft layer that when touched will warp and touch a 2nd layer slightly below it, which will sense the touch and allow finding the coordinates.
The newer screens like on the iphone use another touch sensing process, but those are very new (the iphone was the first portable device to use one AFAIK), and are only becoming widespread in the current generation - i.e. the one AFTER the Kaiser.

He means that even with the stylus or barely touching with the finger the digitizer will slightly "deform", which you can easily see if watching a reflection on the screen and touching it, and the related softness. It's normal and he isn't abusing it.
Hey everyone,
since 2 or 3 months I've got an HTC Kaiser. I really like it, it is equipped with an TF2D integrated ROM, so far everything nice
But as you can see in my device history, I formerly got an HTC P4350, these one was terribly slow! But it had one thing which was a thousand times better than my Kaiser:
The Touch screen was accurate. When I'm working (or whatever) with my kaiser, I sometimes have to tap 5-6 times on the screen until I reach my destination due to the bad touchscreen accuracy.
I tried also a screen allignment but it had no positive effect, it is for alligning the screen and to set the required pressure but thats not what I'm searching for.
I need a screen on which it tap while using Icontact for example and with which I am able to hit the contact which I prefer (and the buttons are really big and not all other ones around... But usually I have to tap several times to reach my destination.
This occurs even a little more whilie using it without a stylus.
And also i think the lowest accuracy is located in the center of the screen. So anyone has an Idea how to solve this matter?
Is a new LCD helpful?
When I used my bosses phone the accuracy was also very low - maybe it is a general problem for the Kaiser? (He has also an HTC Kaiser)
I don't know - so is anyone able to help me with that matter?
Best regards,
Maeffjus
are you using a screen protector?
if so, try removing the screen protector and then check the accuracy.
if the accuracy improves after removing the screen protector, then you can either use the phone without the screen protector or buy a brand new screen protector.
finally, try cleaning under the edges of the frame of the screen with a thin piece of cardboard or a rigid plastic sheet.
No, I'm not using a protector...
I'm often cleaning the screen edges with business-cards (otimal solution *lol*)
The screen was equiped with a protector when I bought the phone but I removed it immediately.
And also the accuracy is bad on my bosses Kaiser...
Hi all,
I have a problem with my phone. When I put it on a material that has good electrical insulating properties, for example on a couch and try to use two or more fingers, e.g. zooming in - zooming out on a picture, the touch sensing of the screen blocks and becomes not responsive. One finger is always sensed but 2 or more fingers are sensed only for a short time or not at all. The more fingers you put on the screen the easier is to make it stop sensing your fingers.
This behaviour is more obvious when you repeatedly move your fingers inward till they touch and outward again.
When multi touch sensing blocks, one way to make it work again is to touch with one finger of your other hand the hull of the phone, e.g. the charging socket of the phone, making in this way a kind of grounding.
For visual demonstration you can use a multi touch sensing app, such as MultiTouch or other similar one.
The problem never occurs when:
- phone is handheld
- it is charging
- it is lying upon a not so good insulator, e.g. on a wood or a whasing machine.
I have made some videos that illustrate the problem:
vimeo.com/300242218
vimeo.com/300242398
vimeo.com/300242502
The strange thing is that I sent my phone to Nokia for repair and they exchanged my phone with a new one which however exhibits the same problematic behavior. This led me to think that many of Nokia 7 plus may suffer from this problem.
Could anyone else please confirm that he/she has the same problem with their phone or not?
