THIS A LITTLE OF THE HISTORY OF MULTITOUCH . The use of touch technology to control electronic devices predates the personal computer. Early synthesizer and electronic instrument builders like Hugh Le Caine and Bob Moog experimented with using touch-sensitive capacitance sensors to control the sounds made by their instruments.[4] IBM began building the first touch screens in the late '60's, and, in 1972, Control Data released the PLATO IV computer, a terminal used for educational purposes that employed single-touch points in a 16x16 array as its user interface.[4] Multi-touch technology began in 1982, when the University of Toronto's Input Research Group developed the first human-input multi-touch system. The system used a frosted-glass panel with a camera placed behind the glass. When a finger or several fingers pressed on the glass, the camera would detect the action as one or more black spots on an otherwise white background, allowing it to be registered as an input. Since the size of a dot was dependent on pressure (how hard the person was pressing on the glass), the system was somewhat pressure-sensitive as well.[4] In 1983, Bell Labs at Murray Hill published a comprehensive discussion of touch-screen based interfaces.[5] In 1984, Bell Labs engineered a touch screen that could change images with more than one hand. In 1985, the University of Toronto group including Bill Buxton developed a multi-touch tablet that used capacitance rather than bulky camera-based optical sensing systems.[4] A breakthrough occurred in 1991, when Pierre Wellner published a paper on his multi-touch “Digital Desk”, which supported multi-finger and pinching motions.[6][7] Various companies expanded upon these inventions in the beginning of the twenty-first century. Mainstream exposure to multi-touch technology occurred in the year 2007, when Apple unveiled the iPhone and Microsoft followed after with the unveiling of their Microsoft Surface table-top touch platform.
