The HTML5 specification introduces many of the necessary components for rich interactive and game development, from <canvas> and WebGL to <audio> and <video>. At the same time, JavaScript implementations have matured to the point where they can now support many tasks which previously required native code. The Web Joystick API presents a new way for web and game developers, as well as interaction designers, to access and use joysticks and other controllers for games. | The HTML5 specification introduces many of the necessary components for rich interactive and game development, from <canvas> and WebGL to <audio> and <video>.
