[Q] Capacitive touch screen problems - General Questions and Answers

My wife is weird. If she is around electronic things it mostly goes wrong. This is very annoying with touch screens. What can be the cause that a capacitive touch screen of a device which reacts perfectly to me hardly does to her? And more important, how to solve it? Wear wool?

Touch Pro - Touch screen much less sensitive than iPhone???

Ever since I got my brand new HTC Touch Pro I noticed the screen to be way less sensitive than my girlfriend's iPhone.
For example in the Contacts app, when I use my finger to scroll down or up I find myself many times opening a contact rather than the screen scrolled down or up. Same goes for many other presses on the screen with the finger. I find myself using much more force than I naturally would use with an iPhone
I wonder if my unit is faulty requirming more pressure to the screen or maybe that just the way it should be by deisgn? I assume only users who used both iPhone and Touch Pro could answer that. I don't know anybody with Diamond or Touch pro so I have no way of checking it other than asking you guys.
Thanks
Iphone and Touch Pro use different types of touch screen.
We have Capasitive screen on iPhone which doesn't require pressure, just a touch.
And we have touch-resistive screens on most of Windows Mobile (inc. Touch Pro) which are less sensitive than iPhone...
Here is a link that might help: http://www.rycom.com.au/capvsres.htm
by the nature of the technology involved to sense your touch, the pro is less sensitive than the iphone.
the iphone uses a capacitive touchscreen which senses the electrical signal around your finger whereas the tp uses a resistive touchscreen which senses where your finger presses the screen in.
resistive screens are designed for sytli, and the "gestures" and flick scrolling implemented on many htc devices are a kind of fudged system to imitate gestures on the iphone. i know on my wizard i could adjust the touch scrolling sensitivity through schaps advanced configuration tool, but i'm not sure if you can do that with the touch pro. its all about how much force/speed you use on the TP.
i know you can get used to it, and it will function properly, but it is definitely different from the iphone. good luck!
Thanks guys. Both of your replies are most helpful. I began to fear that my unit had a fault in it. Seems to make sense that is how it works after I understand it. I most appreciate the responses. Thanks.

You will get better results using software designed from the ground up to be finger-friendly e.g. touchflo3d works well with only light pressure, and for contacts pocketcm also scrolls with only light pressure.

On the plus side, the Touch pro(and all other non-capacitance screens) are less picky. I noticed that if you use fingernails on an iPhone it will ignore you. you have to touch with your finger. Our screen will respond to anything that touches it...pen, fingernail, rock. There are +/- s to both. Just have to get used to the change.
yeah pocketcm is great for scrolling also there is pointui if you dont like touchflo that is a free app that redoes the interface all scrolling too
and i usually use my fingernail for most stuff instead of my finger

I used a metal key depth gauge, and though it felt smooth, it put a nice scratch on the screen. It was a new replacement, and I hadn't got the screen protector yet. Good thing I'm not an anal OCD-head
Stylus' (Styli?) seem to be out of fashion at the moment, but they are far more accurate for doing work in spreadsheets and other applications with lots of data on the screen.

agreed, i have no problem being a "geek" and whipping out the stylus, especially when it magnetically snaps back in
is there a way of using stylus in capacitive screens?
Our fingers eletricity shouldnt be conducted through the stylus metal and reach the screen? Why it doesnt work?
is it true that HTC G1 is capacitive?
G1 is capacitive
Its not so much conducting electricity, more of eminating an electric field. i know there are certain "silver fingered" gloves that let you use the ipod/iphone with gloves on, and i would guess that there are capacitive styli as well, but i havent gone searching one out.

I have been whipping it out in public since the Palm 3.
I sometimes feel that Windows Mobile doesn't make the best use of Stylus input compared to Palm OS (tap a time to create a new appointment for example) but both zip along compared to finger presses on the iPhone for most serious work.

it's due to the resistive touchscreen. it's less sensitive than the capacitive screen in the iphone.
but the touch pro screen is actually less sensitive than other htc resistive touchscreens such as the kaiser. it's much less sensitive e.g. near the edges of the screen because of the bezel underneath, you need to press harder at the edges to get it to register a touch.

Are resistive screens completely obsolete?

Hi there
Currently I have a Touch Diamond 2 and a HD2. As much as I would like to switch to the HD2 I keep on getting back on the TD2. I simply prefer the resistive screen. Although you may have to press a little harder I just prefer the feel and accuracy of the resistive screen. To be able to use my nails (and stylus for that matter) is a big plus I think.
So I was just thinking that some of you may have some insights on where the technology is heading in regards to screen technology. Are resistive screens on their way out? Is there some kind of mix between resistive and capacitive in the works? Or something else/new?
I doubt it, there are multitouch resistive screens, and they are still much cheaper than capacitive screens. I think they'll stay around, but will be on increasingly lower end handsets. Although go look at a demo of stantum touchscreens; they're resistive, yet offer a ridiculous amount of features
At first I was all for the resistive touchscreen on my td2. That was until it decided to break on me, the layers of the screen got stuck together somehow and I had to get it repaired.
Now that I've had the chance to play with the gf's palm pre I am ready to pay extra for a cap touchscreen. It just feels so much more durable and sensitive. I really don't see a need to use a stylus or any other than finger to interact with the screen.
And there aren't really that many applications where you need overly precise touch sensitivity on a smartphone so cap all the way for me at least.
Capacitive screens seem to be the wave of the future. For me, I will never go back resistive.

The stylus is a good feel for us few.
I enjoy both the resistive screen with the stylus and capacitive screens, but finger friendliness is what people look for.
The biggest reason I like using the resistive screen, especially at this time of the year is because I can wear gloves and it still picks up input, where as on my Zune with its capacitive screen it doesn't pick up the input when wearing gloves.
If your talking bout current resistive screens yes.
If your talking about resistive screens like Stantum ones then No.
I really really have a dislike for capacitive. Cant even draw stuff properly on capacitive screens.
Keep in mind that few people draw or transcribe symbols in their phone.
As a matter of fact, the stylus is accurate but it is never smooth as when drawing with a pencil or paint brush and writing letters for that matter.
No matter what stylus and screen you use, your handwriting will be super ugly.
So there is really no logical use for stylus based touch screen.
When a super phone comes out that someone likes, I will promise you that he or she will enjoy capacitive more. And even if resistive screens also support multitouch, you still have the feel that your screen is unresponsive.
Most people expect touch screens to be so sensitive that pressure is almost not even needed.
For many phone users the capacitive screen is a better choice, where response is more important than accuracy. But there will still be a need for resistive screens for some buisness applications where accuracy is of importance.
I need my stylus
Resistive is just more versatile for my tastes.

I thought the whole point with the next gen resistive screens, besides multitouch, is that they are supersensitive.
I dont know if youve seen the tech demos. I dont have any links for the videos right now. What ive seen from those videos it seems sensitive enough.
However im guessing that we wont see this tech on phones for a while. Because of the iphone and it having a capacitive screen people have got it into their heads over the years that capacitive is the future. Now winmobile 6.5 phones are coming with capacitive screens and winphone 7 devices will be capacitive only.
So we probably wont see this for some time to come.
Also I think the tech for the newer resistive screens isnt ready
for markets. It seems more like just prototypes and it's probably
alot more expensive than capactive screens.
Am I wrong on this?
Here is a article about (capacitive) screen / the iPhone screen in particular....
http://www.crunchgear.com/2010/02/1...ll-have-the-best-touchscreen-in-the-industry/
I agree with the author and I also really don't get why development hasn't been pushed further on this point.

Is capactive really BETTER than resistive?

Most of the latest smartphones and upcoming phones appear to have capacative screens and they seem to be the preferred type. However, I still use a resistive screen and I recently borrowed an HTC HD2 with capactive screen and I was not that impressed.
Certainly, they do resopond to a lighter touch but for me that was an irritation as I would regularly accidentally touch/select something by mistake. My Touch Pro2 resistive screen does not require much more pressure on the screen but just enough that it is hard to select something accidentally. I also like to use my finger nail to select which of course you cannot do with a capactive screen. Selecting some of the smaller menus in Windows Mobile is quite difficult on a capactive screen.
The other reason I like using my finger nail is to minimize finger marks on the screen. I noticed when using a capactive screen that it was covered in finger marks very quickly.
So, are capactive screens really "better"? I have held off upgrading my Touch Pro2 as I do not think that capactive screens are better than some of the latter resistive screens. However, it seems that if I do want to upgrade my phone in due course I am going to have to go with a capactive screen.
Maybe my Touch Pro2 will serve me for a while longer yet!
Well,first off,windows mobile isn't so finger friendly.If you use android with a capacitive screen it's much more pleasant.Secondly,capacitive screens allow the use of better materials like glass,which are more scratch-proof(see HTC HD2 and knife video at youtube to see what I mean),offer better image quality and phones using capacitive screens can be thinner.There is more,but that's what I can think of now!
Hope it helps!
It depends on what you're using it in, but I prefer a nice resistive screen over capacitive: almost as sensitive, and you can use a stylus. Although I have yet to see a multitouch resistive screen on winmo.
Yes capasitive is way way way better and more responsive. You can't stylus it in fine detail like a resistive LCD but the capasitive screens are super sensetive and you don't have to hit the same button like 3 times. On the other hand if you looking to hit a tiny small little spot its sometimes kinda hard with the capasitive LCD, but can be done with a lil practice and knowledge of how it works.
I tell people to get the HD2 over any old winmo phone even if it's just for the capacitive screen.
Windows Mobile and resistive screens always went together because resistive screens supported stylus input, necessary to hit WM's ridiculously small buttons. Nowadays Android, iOS, and Windows Phone 7 have been re-imagined with finger usage in mind and a capacitive touchscreen is by far the best way to control a phone with just your finger. Personally, I never liked the "feel" of resistive screens, whether I was using a stylus or my finger; it's hard to pinpoint exactly what I mean, but when I switched to capacitive I had no desire to return to resistive.
All that said, resistive is still the king for any sort of handwriting recognition or things that require the precision only a stylus can supply.
Yeah once you try capacitive properly you'll never go back... being able to TOUCH not PRESS is so much better, makes the touchscreen interface much more pleasant. Its better for not just pressing, but sliding etc.
Not to mention mulitouch
Although not winmo, a good device that I'd consider an upgrade to a Touch Pro2 with a resistive screen is the Nokia N900. It's sensitive enough that a fairly light touch works fine, but not overly that accidental touches will register.
I do personally like capactive screens though, on most phones.
I'm a fan of resistive screens, if you are using VNC etc to control a desktop machine
from your phone you really need a stylus.
For everday phone use capacitative is better..
Problem with the HD2 is that the screen sensitivity is very high, especially in the 1.48 ROM that most devices ship with. I am using a custom ROM and then I also reduce the screen sensitivity using BsB Tweaks and precision is very good.
I wonder if they will come out with a capacitive screen pen to be able to use handwriting recognition on the newer screens. I am old school and did not learn typing, so I am a multi-finger hunt and peck kind of guy when I type, although with only being able to use two thumbs or less on the phones pop up keyboard I do not think I would have too much trouble if I lost the ability to handwrite. I just find writing more natural. I really like my handwriting recognition on my Fuze.

It's WM fault, not screen fault. Try high-quality restive screens with Symbian (N97), no need to re-hit
My vote is for resistive. Most productivity software (like Excel Mobile) works MUCH better with a stylus. I can comfortably and accurately work with EM at 50% zoom on a Fuze. Except for dialing and SMS, I use the stylus for everything. No matter how sensitive capacitive is, you will never be as accurate with your finger as a stylus.
I'm just getting a tp2 now. I think it's going to be my last phone for a LONG while. I need a resistive screen and slideout keyboard, since my only concern is being productive with productivity software. I don't know of any phones in the works that offer the combination I need.
Well,when speaking about hardware and screen size like the Hero's then yes,resistive might be more accurate(for me not better at any rate),but when speaking about high-end phones,such as the Desire(Classic,HD and Z) or the Galaxy S,with so much power and such big screens,all this talk about them lacking accuracy is complete mumbo-jumbo(I'd be rude if I said bull****,wouldn't I? ).Have you ever tried these phones actually?They make my (old) Diamond's screen seem like a child's toyphone or some badly made copy of a current phone.
Plus the fact that with resistive you can use high-quality glass with scratch proof coatings instead of plastic is a huge advantage for me!
Just my opinion though!
The only thing I like about capacitative screens are the durability aspect. The biggest thing I hate? Can't use anything but your finger (those fat styluses are just as good as using your finger...). I'd go capacitative anytime though just for durability. I like knowing that my device will last.

Opinion on screen damage

Hi all,
I work for a company that has a lot of HTC touch2 phones. We've had a lot come back recently with similar 'unexplained' damage to the screens which stops the touchscreen part from working. The screen itself seems fine though. I've taken a picture one and attached it.
Does anyone have any idea what might cause this? I'm presuming just screen pressure but it'd be nice to be sure
Cheers
Louis
It's showing the "oily smear" issue which seems quite common with HTC's resistive touchscreens. I have a problem with it on my Touch Pro, although the touchscreen is generally usable - it sometimes requires some rubbing to "unstick" the layers of the touchscreen before it works though. When it first happened, the screen didn't work at all.

It seems to be related to excess pressure, but it's pretty common it seems. Mine was just in its T-Mobile provided case in my pocket when it happened.

[Q] How to adjust screen sensitivity?

Screen is way too sensitive. It often registers touch before I touch the screen. Using fleksy is a real *****.

damn, i have this issue on the galaxy tab s 10.5 i am returning to get the shield tablet, sad to hear its also an issue here. what is nuts is you can make the sensitivity even HIGHER (but not lower derp) on the tab s 10.5. it does the same thing, just hover above it and it registers a touch.
I can't believe there isn't more posted on this topic. My screen can register a touch almost a half inch off the screen. Is there any way to fix this?
