Based On The The Wince Touch Screen Applications

Recently, with the rapid growth of Embedded System, Real-time OS, Embedded CPU, Software and Human-Computer interaction have become the hot spots in the research of Embedded System. Among them, Human-Computer interaction technology receives great concern.Nowadays, the computer application technology, the communication and the sensing technology may say are the electronic information technology three big main props, and they are respectively the intelligent system the sense organ, the nerve and the cerebrum. Among them, the computer and the communication development are developing rapidly, however, sensing technological development falls behind. Therefore, various countries all regard the sensing technology one of modern information key technologies.This article based on Microsoft's real-time operating system WINDOWS CE, has discussed the thorough research and the further development. This topic mainly solves several key questions: 1) calibration algorithm; 2) touch screen filtration algorithm realization as well as the optimization; 3) carries on the optimization to the mouse event triggering method, realizes the vibration algorithm: At present mature algorithm is in need in industrial application; 4) the realization of touch screen driver under WINDOWS CE. Based on WINDOWS CE, the existing touch screen hardware resources and the correlated algorithm are unified to realize the great-size touch screen driver. This method which has improved the hardware and the correlated algorithm design, has greatly improved the accuracy and stability of this man-machine interaction technology, and has urged widespread application of the great-size touch screen.In the WINDOWS CE foundation, this article also aims at the request of the Guangzhou subway line users, studied and designed touch screen man-machine interaction system in subway, and has satisfied user needs and so on meet timeliness and accuracy, has achieved the anticipated performance.Finally, the summary is given and next researching field is proposed.
