How does Multitouch work?
In computing, multi-touch refers to a touch sensing surface's (trackpad or touchscreen) ability to recognize the presence of two or more points of contact with the surface. This plural-point awareness is often used to implement advanced functionality such as pinch to zoom or activating predefined programs.
Usage by Apple[]
Apple popularized the term with the introduction of the capacitive multi-touch LCD on the first iPhone in 2007. The device also contained accelerometers and gyroscopes that could detect the orientation of the screen and adjust the video display.[1]
Apple Computer had quietly acquired FingerWorks in February 2005 to secure its technology and hired co-founders Wayne Westerman and John Elias to continue developing it as multi-touch for Apple's iPhone, iPod touch, and iPad product lines.[2][3][4]
