The Research And Application Of Embedded Interface Design

When the human-computer interface design appears massively, the technique of its interface design is also unceasing enhancement and popularization, and also more and more user-friendly. The embedded human-machine interface design was a branch of interface design. It not only may satisfy the interface design request, but also the special request of embedded environment.With the development of microelectronics technology and ultra large scale integrated circuit technologies mature, embedded system is growing rapidly and becoming more powerful. With its small size, low power consumption, cost-effective, easy to carry, and other unique advantages ,the embedded system is playing an increasingly important role in communication, management, medicine, seismology, meteorology, aerospace and education sectors.Embedded image processing system is implemented on the embedded device platform for image processing. It needs friendly and simple interface design, and should take into account the complexity of image processing, such as reading, moving, zoom and drawing functions. Therefore, the file system module should be extended on operating system .We should also consider supporting issue on the hardware interface. With the embedded processor performance increasing and the emergence of dedicated graphics acceleration chip, the embedded platform is possible for fast and high quality image processing. According to the needs of interface design, the realization of the image processing is becoming increasingly easier and runing faster.In this thesis, , we have done the following work 1) Comparing the differences between the two interface design of MiniGUI and Qt / Embedded in the Linux operating system. The main content is to introduce the installment and the design of interface design under Windows CE, MiniGUI, Qt/Embedded and complete the programming of interface design. 2) The application procedure of picture showing and loading is joined to the interface design to make it applicable and feasible; 3) The image processing program in three different environments is ported to the hardware platform, as this several interface designs need different hardware configurations, there is a need to optimize and transplant in comparing these types of system hardware configuration.4) Comparing different interface design for image processing speed and sensory effects ,as the original system is optimized for interface design to improve the graphics processing speed.
