INTRODUCTIONWith the development of puter technology, embedded system has bee an important part of the puter field．The socalled embedded system, that is, a special puter system with application as center, puter technology as the basis，software and hardware can be tailored to meet the application System strict requirements for functionality, reliability, cost, size，and power consumption．Embedded puter far exceeds a variety of generalpurpose puters in the number of the applications，manufacturing industry, process control, munications，equipment, instruments，automobiles，ships，aviation, aerospace，military equipment, and consumer products are all the application field of the embedded puter．Ⅱ． USER INTERFACE BASED ON EMBEDDED LINUXA. Embedded operation systemEmbedded system has useroriented, productoriented, applicationoriented features．Different from general—purpose puters，embedded system is a special system for specific applications，generally is costsensitive， and its hardware and software must be efficiently designed, tailored to remove redundancy．A good embedded system is the minimum system to plete the target functions．In embedded system development, embedded software is the key to achieve a variety of system functions, also one of the most active research directions of puter technology．In general，embedded system consists of hardware and software two major ponents．The hardware part includes processors／microprocessors，memory，peripheral devices， I／0 ports，graphics controller and so on．Embedded system is different from the general puter processing systems, which does not have a largecapacity storage medium as hard drive．but most use EPROM，EEPROM．or flash memory as storage medium．The software part includes operating system software which needs realtime and multitasking operations，and the application programming．The operating system controls the application programming and hardware interaction, and the application controls the system operation and behaviors．B． GUI overviewThe broad popularity is one of the major achievements of current puter technology，which greatly facilitates the use of nonprofessional users，and people no longer needs to cram a lot of mands．but can easily operate through the window and menu．A GUI system is usually posed by three basic levels which are display model, window model and user model． User model contains the main features of display and interaction, thus the term of GUI sometimes only refers to the user model．Figure 1 is the GUI system hierarchy structure.Desktop management systemUser modelWindow modelOperating systemHardwareFigure 1.
