Comments on: Is capacitive touch screen all hype?

does capacitive screens must have the mass or the volume of the human body to work? could it work with a battery? or any other electrical charged object? i have tried with a steel metal ball (30mm diameter) and it worked quite well without touching my body, i’m confused.
you mentioned the body’s electromagnetic field, would a magnet could compensate it?

It looks like capacitive screens have won in the marketplace, for better or for worse. I will be holding on to my resistive screen phone as long as I can. I like to be able to take handwritten notes with my stylus. The resistive screen I have is very accurate, with finger or stylus, unlike some have claimed above. The consumerization of IT continues…

Why do you prefer a screen that will only respond to a human finger, and can’t work in cold weather? A resistive screen responds to finger nails and pens – or anything. A finger nail and a pen can be much more precise than a great big soft squashy finger.

I don’t get it.

I think capacitive screens are only popular because they are on Apple products, and anything on Apple MUST be the “best”…

Surface Acoustic Wave screen has the highest durability and clarity and the panel is all glass panel. This technology uses ultrasonic waves that pass over the touch screen panel. Due to high durability and clarity, it is better than capacitive but we need to keep in mind that different technologies have different uses depending on the business requirements. SAW is the technology that is used for most of the ATMs but use of other touch screen types is not too uncommon.

Which type of touchsreens are used in ATM and what about surface acoustic wave technology, is it better than capacitive type?

The capacitive touch screen requires body’s electromagnetic field. In cold weather when the fingers become very dry, the required electromagnetic field cannot be created and hence the distortion is not sensed by the screen. This is the reason why the capacitive screens do not work in all weather conditions.

Can someone tell me why capacitive screens dont work well in all weather conditions?

i for one have used phones of both types. presently the phone that i have, with its capacitive touch screen, gives the most amazing touch experience. the accuracy is great, the sensitiveness too. i can literally text without having to cancel errors. whereas the nokia 5800 that i used, with its resistive touch was way too horrible!!! i hated it for the frustration it gave me while typing just one sentence!! too many errors!! capacitive touch screens are the future, totally!! i mean, ultimately, everything comes down to user friendliness. not the software behind it or whatever! the average user doesnt care about the software!! and as far as the grapewine goes, capacitive screens are doing pretty well. slowly taking over.=)

Right.. Abhishek.

The primitive resistive screens are not that responsive as capacitive screens. Also resistive screens do not offer multitouch capabilities (to date). The touch error rate is very high on resistive screens. So users get frustrated to see that actions is not done even after touching the screen. You must have see this if you have a phone with resistive screen. You will never see this in capacitive screens.

That’s an interesting point you made. While I agree with the overall message, I think there are 2 critical points which device makers will do well to take a note of while choosing a panel type:

1. Instant gratification: one of the most imp reasons why capacitive panels are gaining rapid popularity amongst users. With more and more focus on the s/w, users expect quick response from the display the moment the gesture is made. Even in some of the best resistive panels, I’ve observed that the latency is way too high as opposed to the capacitive displays. Accuracy of the touch is also an issue.

2. the Apple benchmark: the advent of the iPhone and its amazingly responsive capacitive panel has raised the bar of touch-screen displays really high – anything short of that will really fall flat on its face. Nokia has learnt this lesson the harder way and I think the N900 is really a step in the right direction.

What’s more surprising is the fact that not many industry folks saw the capacitive displays arriving. I remember doing some research around the displays – IDC forecasts drew a pretty dismal picture for the capacitive display panels just 12 months ago.

Overall, my sense is that capacitive displays are the future as far as consumer user cases are concerned. Sure, resistive varieties will continue to be deployed in industry verticals, but I won’t be surprised if that is showing a downward trend.
