INTRODUCTION(TOUCH SCREEN)
A touch screen is a display which can detect the presence and location of a touch within the display area.
One point of contact at a time.
INTRODUCTION…..
Multi-touch technology is an advanced human-computer interaction technique that recogonises multiple touch points and also includes the hardware devices that implement it, which allow users to compute without conventional input devices .
Multi-touch technology dates back to 1982, when the University of Toronto developed the first finger pressure multi-touch.
In 1984 Bell Labs engineered a multi-touch screen that could manipulate images with more than one hand.
In1991 Pierre Wellner published a paper on his multi-touch “Digital Desk”, which supported multi-finger and pinching motions.
In 1998, Fingerworks, produced a line of multi-touch products including the iGesture Pad and the TouchStream keyboard.
