Call it an effort of human mind or a miracle from human heart. But this is all happening with technology. We land in an era where everything that can be possibly thought, can also be practically put into. And that too quite reasonably..!! Just move the hand or walk your fingers over a thing and it works. Yes, it is the interactive gesture based technology I am talking about. A device which works on touchscreen technology is coined as Touchscreen. A touchscreen is an electronic visual display capable of ‘detecting’ and effectively ‘locating’ a touch over its display area. It is sensitive to the touch of a human finger, hand, pointed finger nail and passive objects like stylus. Users can simply move things on the screen, scroll them, make them bigger and many more.
Everything in today’s digital devices world is becoming a touch away. Whether it is filling an early morning coffee mug or setting the timer for washing machine or turning ON the display of your PC.Capacitive Touch Technology is widely used in touch sensing devices. Less time response and environment adaptive features made it popular between the manufacturers. Some more applications are water purifiers, kitchen appliances, vending machines and switches.Most of us have surely come across capacitive touch sensor in our day to day life but how many of us thought about the working principle behind it.Change in capacitance is used to sense the touch in capacitive display. Amazed? How can a two metal plate component which stores charge can sense the touch? Answer to the above question will be explored in this Insight.
While we are all fascinated by the touchscreen-market gimmick cajoling us with its ‘Touch away’ tagline, are we actually only at an inch’s distance? This ‘no-distance’ de facto makes sense at the front end only. When given a hawk’s eye, there is another world inside waiting to be discovered, waiting to satiate your knowledge for technology. Well, for the smart gadgets with smart people in the smart world, it’s an uncanny missing out a discussion on Touchscreen Technology, specifically undertaking the Multitouch Technology. The multi-touch or the plural touch is an interactive technique which allows users to interact with the digital environment inside the gadget, directly or indirectly with his fingers or palm. Multi-touch devices include smart phones, touch tables, computer tables, public kiosks, walls, and ‘touchpad’. Well these inverts in touchpad bring us to a minute line of demarcation between touchscreen and touchpad.
