Multi-touch Plug-in System for Web Browsers

The patent introduces a plug-in as an intermediary component that runs within the sandboxed browser environment and acts as a mediator between the multi-touch hardware and the web application. The plug-in receives multi-touch input data from the operating system, processes and translates it into a standardized format, and makes it available to the web application through safe, controlled interfaces. This intermediary approach allows the sandbox to maintain its security boundaries while still enabling multi-touch functionality through the trusted plug-in layer.

The patent creates a universal plug-in architecture that can handle multiple types of multi-touch gestures and interactions through a single, standardized interface. The plug-in translates various platform-specific multi-touch input formats into a common gesture framework that web applications can consume. This universal approach allows the sandboxed environment to provide consistent multi-touch functionality across different platforms and input devices without requiring separate implementations for each gesture type, thereby maintaining system stability while enhancing adaptability.

The patent segments the multi-touch processing functionality into distinct layers: the operating system handles raw touch hardware input, the plug-in processes and translates the data into standardized gestures, and the web application consumes the processed gesture data. This segmentation allows each layer to operate independently within its own security boundaries, with the plug-in acting as a trusted bridge that enriches multi-touch capabilities without compromising the sandbox's security model. Web applications can access sophisticated multi-touch gestures without directly interfacing with the complex touch hardware or operating system drivers.
