Recently a W3C working group has come together to work on this touch events specification. Android has been catching up to this de-facto standard and closing the gap. For example, nearly any fast-paced game requires the player to press multiple buttons at once, which, in the context of a touchscreen, implies multi-touch.Īpple introduced their touch events API in iOS 2.0. ![]() As the mobile web evolves to enable increasingly sophisticated applications, web developers need a way to handle these events.
