Touch technology is becoming ubiquitous. Blame it on Windows 8, or blame it on the simplicity that it delivers. But it’s here to stay, and that’s a good thing. To simplify the design of touch-based products, particularly for mobile devices like smartphones and smaller tablets, Atmel has developed the mXT640T, mXT336T, and mXT224T touchscreen controllers. The devices provide a comprehensive set of touch features to support touchscreens ranging from 3.2 inch to 8.3 inch.
The devices’ features include a 1-mm passive or active stylus hover capability, moisture immunity, and multi-finger glove support. The parts incorporate Atmel’s adaptive sensing technology to enable dynamic touch classification, a feature that automatically and intelligently switches between self- and mutual-capacitance sensing to provide users a seamless transition between a finger touch, hover, passive, or active stylus, or glove touch. This eliminates the need for users to manually enable glove mode in the operating system to differentiate between modes. Adaptive sensing also reduces the device’s power consumption. The analog front-end offers flexible settings to maximize the signal-to-noise ratio (SNR) prior to digital processing, eliminating signal distortions induced by water and noisy chargers.
A touch responsive surface is used along with the sensors , Sensors have current passing when this current touches the surface it gets converted into voltage . A controller that is the hardware is used which converts voltage into signals. A software tells the computer the mobile or any device whats happening on the sensor who is touching what and where .
These touch technology is widely used in ATM machines, car navigation system, medical monitors,Industrial control panels, mobiles. Laptops , tablets not only this but electronic appliances used in house hold also have touch technology like in fridge, freezers, microwave, electric oven and so on . In short we can say that this technology is on its way towards boom.
Touch screen is no doubt a very easy technology that has developed . Initially it has limited users and only i guess youth were interested in using touch technology fones but as the technology has evolved, developed, revised and more applications associated with this technology has developed people are not just using this technology for the sake of use it has now become the necessity of the life . According to me its an excellent job done by Steve Jobes he has worked on a very complex aspect of marketing that is developing the need of a new technology these days technolgies are developed according to the present needs of the people but this touch technology has gone in the other way round it was first developed and after that the need was created an excellent marketing approach .
Touch technology is indeed becoming ubiquitous. And not is this common for mobiles and tablets, but recently researchers in University of Washington has found a way to convert a standard LCD monitor into touch screen using a wall mounted EMI sensor that costs only $5. The technology is called as "uTouch". So touch and gesture technology is becoming a very common and essential part of modern era.
Initially, touch-screens were simple resistive Mylar films. Two opposing layers coated with a transparent, conductive ITO to create a 'short' when depressed. Actually, very basic. Soon after, came capacitive screens which offered better tactility with improved registration for pinpoint response. But it was simultaneous multi-touch that really blew the lid off touch-screen technology, and committed touch screens to become an integral part of the human experience forever.
Wow- pretty harsh words for the dearly departed Mr. Jobs. On another UI topic, although he didn't invent the mouse, he did advance its adaptation by massive commercialization of that User-Interface. How do you feel about that one-?
nothing wrong with touch that a good keyboard can't cure. for me, steve jobs eternal damnation is his resistance to the traditional inteface. rather than supplement or grow options, he wanted to supplant and limit them. worst thing to happen to technology in my lifetime.
You're right that this technology delivers simplicity, Rich. I actually am surprised at how successful it is and that there aren't more problems with it. I have been using touch technology since the very first iPhone and, except for a few glitches here and there when I've spiilled water on my device (but only temporary glitches), it rarely fails. It's good to see more options like this for adding it to other devices.
