The researchers at Fujitstu laboratories had created something new for the next generation user interface which allows the interface to detect the user's finger when users touch the screen. Many objects could be manipulated by touching that screen which is more like an ordinary webcam and a commercial projector . The capabilities of this interface can be achieved through image processing technology.
The users can simply import the data from selected document and then they need to highlight the important parts of the document that users want to collect using this touchscreen interface. Basically, this touchscreen interface is able to measure any shape of a real world objects and then it adjusts the coordinate systems for the projector, camera, and real world. On top of that, the objects with curved surfaces can also be coordinated just by touching.
This system combining both analog operations and digital devices so that it can be operated when user point with their one finger only. The system would need to detect the fingertip height exactly as well in order to have the touchscreen interface detect touches accurately. If the finger detection is off just by a single pixel, the height of images will change by 1 cm. Besides that, this kind of interface also has a technology which is the system enables to control the color and brightness in order to get the quality of images as required by users.
