【摘要】：随着社会的迅速发展和竞争的愈加激烈，人们的学习需求也随之日益增加。如今，在发展迅速的无线互联网时代，智能手机和平板电脑的硬件性能越来越高，而价格却不断下降，使得学习者可以方便使用智能手机或平板电脑来进行学习。移动学习正是伴随这个大背景而发展起来的一种新型数字化学习方式。毫无疑问，移动学习必须基于可用性高的移动学习软件才能得以开展。现有Android屏幕共享应用较少，其中功能相对完善的应用，一般价格比较昂贵且不开放其实现方式，不利于开展移动学习及学术交流。另外，这些屏幕共享应用并没有为实施移动学习进行额外的优化与设计。本文正是针对以上两个问题，对支持移动学习的Android屏幕共享进行了深入研究。首先，本文在初步研究移动学习及屏幕共享相关理论基础上，，进一步分析Android屏幕共享所需的关键技术，并依据支持移动学习的屏幕共享设计原则确定了屏幕共享实现方案。其次，本文深入研究了屏幕图像热点捕捉技术，并提出一种自适应屏幕图像变化方式的热点捕捉技术，同时利用该技术对文本屏幕共享性能进行了优化。最后，本文实现了支持移动学习的Android屏幕共享应用，并进行性能测试与分析。本文所提出自适应屏幕变化的热点捕捉技术，性能优秀，是本文的主要创新点。进一步，本文所设计并实现的Android屏幕共享，非常适合于移动学习环境下使用，功能完善，兼容性高，实施简单，占用资源少。
[Abstract]:With the rapid development of society and the increasingly fierce competition, the demand for learning is also increasing. Nowadays, in the era of rapid development of wireless Internet, the hardware performance of smart phones and tablets is getting higher and higher. Prices are falling. So that learners can easily use smart phones or tablets to learn. Mobile learning is a new type of digital learning developed with this background. There is no doubt. Mobile learning must be based on high availability of mobile learning software can be carried out. The existing Android screen sharing applications are few, among which the function of relatively perfect applications. The general price is more expensive and does not open its implementation, is not conducive to the development of mobile learning and academic exchanges. In addition. These screen sharing applications do not carry out additional optimization and design for the implementation of mobile learning. Aiming at the above two problems, this paper makes an in-depth study on Android screen sharing which supports mobile learning. First of all, based on the preliminary study of mobile learning and screen sharing theory, this paper further analyzes the key technologies of Android screen sharing. According to the design principle of screen sharing which supports mobile learning, the realization scheme of screen sharing is determined. Secondly, this paper deeply studies the hot spot capture technology of screen image. A hot spot capture technique of adaptive screen image changing mode is proposed, and the performance of text screen sharing is optimized by using this technology. Finally. In this paper, Android screen sharing application supporting mobile learning is implemented, and its performance is tested and analyzed. The hot spot capture technology of adaptive screen change proposed in this paper has excellent performance and is the main innovation of this paper. Further, the Android screen sharing is designed and implemented in this paper. Very suitable for mobile learning environment, perfect function, high compatibility, simple implementation, less resources.
