The document outlines the development of a multi-touch interactive screen system that uses human-computer interaction through gesture recognition, aiming to eliminate the need for conventional input devices. It discusses the system's framework, components, applications, limitations, and future enhancements such as multi-user capability and advanced body tracking. References to various research and existing technologies are included to support the project's foundation and goals.

6. HCI (Human Computer Interaction) system.

7. Interact with hand gestures(shapes).

8. Extension of interactive wall ‘09Introduction:Motivation:1. “Interactive Wall 2009”. 2. multi touch technology 3. large size of touch screen with appropriate cost. 4. flexibility.

9. future without annoying input devices, and to be proud of being a part of accomplishing such a dream.develop the Interactive Screen System to be able to handle more features and gestures and to get over its limitation which will make the user get satisfied with its usability and flexibility of use.
