【摘要】 随着计算机技术及触摸屏技术的发展,触摸屏的使用越来越普遍,这极大的改变了人们的生活方式,人们越来越习惯于触摸屏的使用,如各种手持终端设备、ATM等。而其中的多点触控技术近来尤其受到青睐,它彻底改变了以往的触控方式,成为时下最热门、最时尚及最受欢迎的技术,其必将成为每一部高端设备标准配置。鉴于多点触控技术的持续升温,本文采用Meego+ATOM的软硬件设计方案来着手这方面的研发设计。Meego是Inte1和Nokia合力推出的开源操作系统,它完全基于Linux内核,因此非常适合触摸屏驱动程序的开发。硬件平台是采用Intel推出的基于ATOM的嵌入式实验平台。通过搭建Meego操作系统,完成平台构建,并结合硬件平台进行触摸屏驱动程序的实现、移植,完成Meego的内核编译；然后通过安装并改进MTF开发库来完成上层对多点触控的支持,完成应用程序的设计,用此来测试驱动程序和MTF的可用性；最后分析电阻屏在多点触控下的应用情况,并提出基于电阻屏的多点触摸方案并给出应用程序测试结果。本文采用Meego+ATOM的设计方案来实现多点触控,目前尚未有类似的设计方案提出,并且文章尝试提出基于电阻屏实现多点触控,这又是设计的独特之处。电阻屏造价低、对环境适应强,目前电阻屏的应用非常广泛,因此若是电阻屏能在对多点触控的支持上有所改进,那将带来极大的好处。所以本文就是针对此而提出的,并将带来非常好的应用价值。
【Abstract】 With the development of computer technology and touch screen technology, the use of the touch screen is more common, this greatly change the way people live, people are increasingly accustomed to the use of the touch screen, such as a variety of handheld terminal equipment, ATM and so on. Recently multi-touch technology is particularly popular, it completely change the touch way, and become the hottest fashion and the most popular, and it will become the standard configuration of each high-end equipment.In view of the multi-touch technology continue to heat up, this article uses Meego+ATOM hardware and software as the design to begin the R&D. The Meego is the open source operating system that is together launched by Intel and Nokia, it is entirely based on the Linux kernel, so it is suitable for driver development. The hardware platform is based on ATOM embedded experimental platform launched by the Intel. By building Meego operating system, complete building platform,and complete the implementation and transplantation of the touch screen driver by combined with the hardware platform and complete compiling of the Meego kernel; then install and improve the MTF development libraries to complete the upper supporingt multi-touch, complete the application program designed to test the availability of the driver and MTF; finally, analyse the application of resistance-screen about multi-touch, and proposed multi-touch screen based on resistance, and give application test results.This article designs to achieve the multi-touch through Meego+ATOM, currently there is no a similar design to propose. And the article attempts to put forward the multi-touch screen resistance, this is another unique feature of the design. Screen resistance, low cost, environmental adaptation, and resistance screen is widely used, therefore, if the resistance of screens hava improvements on the multi-touch, it will bring great benefits. So for this, and will have a very good value.
