Principle Window interactive bases on advanced computer vision technology to convert touch signal of the finger to direct mouse control. It is a natural interaction. Window interactive is very adaptable to various environments; unlike ordinary touching screen, it is not subject to natural conditions (e.g., temperature, humidity) of the surroundings. Any interactive size can be customered. With the system, users can not only watch high-quality projection image, but also inquire certain information interested by touching the glass cover surface. The system will display pre-set information automatically while it has been idle for a certain period, and switch into the interactive mode when it is touched. Components There are four components in the multi-touch interactive system: 1. Sensor: catch shooting according to the demand; 2. Core control software: analyzing the updating data , built in the computer system; 3. Imaging: present the images in a specific place by using projector. 4. Auxiliary equipment: such as transmission lines, installation components, audio devices, Infrared lights and so on. Installation and Operation The projector could be set on the ceiling of the roof behind the screen or placed inside a machine box together with the sensor and computer. It is also possible to integrate the whole system as an information kiosk. Environment condition: 1. No disturbing IR light. 2. Enough ambient light in front of the screen Application field 1.
