The multi-touch and gesture control of iPhone is based on the technology developed by FingerWorks. The touch screen of iPhone has the function of heat dissipation, and users can slide their fingers on the touch screen to operate the mobile phone. Although the stylus can be used to touch the screen with the fingers of the iPhone, most gloves and stylus will hinder the necessary conductivity. IPhone 3GS later had an anti-fingerprint and oleophobic coating to prevent users' fingerprints from being left on the iPhone screen.
