Ever since Apple unvailed the iPhone with a touch screen display, everybody seems to be want to develope some sort of touch screen device. The computer company HP announced that within 18 months they should have a touch screen monitor for sale.
The technology is going to be brand for for the touch screen device. Simply trying to use the iPhone's touch display will just not cut it with a large monitor for that fact that it will be too expensive. Here is the new technology explained in detail:
HP’s personal computer and Microsoft Surface Table and Touch Wall rely on cameras built into the four corners of the monitors to make their touch screens react. These screens generally use LEDs to shine light across the surface areas. When a finger interrupts that light pattern, the cameras sense where the finger (or fingers) are based upon how the light scatters and react accordingly, all without the need for either a network of chips underneath the screen or pressure-sensitive films.
But between the large-screen touch offerings and the existing capacitive screens on cell phones, notebooks and tablets have languished, with most using resistive screens, which measure touch via pressure applied using a stylus or fingertip. Many tablet and laptop makers have capacitive screens in their product road maps, but in order to really drive adoption, they’ll need to incorporate applications that take advantage of touch.
The market for laptops with touchcreens is probably the ripest one for HP, as people are accustomed to using touchpads and the like with them already. On a dedicated desktop, it will take a lot of extra utility to overcome the mouse as the pointer of choice. But we all often point at our computer, even if it's only one finger, and yell at it too. It's almost inevitable that we'll eventually get rid of the middleman -- the mouse --altogether.
