【摘要】：隨著社會(huì)的迅速發(fā)展和競(jìng)爭(zhēng)的愈加激烈，人們的學(xué)習(xí)需求也隨之日益增加。如今，在發(fā)展迅速的無線互聯(lián)網(wǎng)時(shí)代，智能手機(jī)和平板電腦的硬件性能越來越高，而價(jià)格卻不斷下降，使得學(xué)習(xí)者可以方便使用智能手機(jī)或平板電腦來進(jìn)行學(xué)習(xí)。移動(dòng)學(xué)習(xí)正是伴隨這個(gè)大背景而發(fā)展起來的一種新型數(shù)字化學(xué)習(xí)方式。毫無疑問，移動(dòng)學(xué)習(xí)必須基于可用性高的移動(dòng)學(xué)習(xí)軟件才能得以開展�，F(xiàn)有Android屏幕共享應(yīng)用較少，其中功能相對(duì)完善的應(yīng)用，一般價(jià)格比較昂貴且不開放其實(shí)現(xiàn)方式，不利于開展移動(dòng)學(xué)習(xí)及學(xué)術(shù)交流。另外，這些屏幕共享應(yīng)用并沒有為實(shí)施移動(dòng)學(xué)習(xí)進(jìn)行額外的優(yōu)化與設(shè)計(jì)。本文正是針對(duì)以上兩個(gè)問題，對(duì)支持移動(dòng)學(xué)習(xí)的Android屏幕共享進(jìn)行了深入研究。 首先，本文在初步研究移動(dòng)學(xué)習(xí)及屏幕共享相關(guān)理論基礎(chǔ)上，，進(jìn)一步分析Android屏幕共享所需的關(guān)鍵技術(shù)，并依據(jù)支持移動(dòng)學(xué)習(xí)的屏幕共享設(shè)計(jì)原則確定了屏幕共享實(shí)現(xiàn)方案。其次，本文深入研究了屏幕圖像熱點(diǎn)捕捉技術(shù)，并提出一種自適應(yīng)屏幕圖像變化方式的熱點(diǎn)捕捉技術(shù)，同時(shí)利用該技術(shù)對(duì)文本屏幕共享性能進(jìn)行了優(yōu)化。最后，本文實(shí)現(xiàn)了支持移動(dòng)學(xué)習(xí)的Android屏幕共享應(yīng)用，并進(jìn)行性能測(cè)試與分析。 本文所提出自適應(yīng)屏幕變化的熱點(diǎn)捕捉技術(shù)，性能優(yōu)秀，是本文的主要?jiǎng)?chuàng)新點(diǎn)。進(jìn)一步，本文所設(shè)計(jì)并實(shí)現(xiàn)的Android屏幕共享，非常適合于移動(dòng)學(xué)習(xí)環(huán)境下使用，功能完善，兼容性高，實(shí)施簡(jiǎn)單，占用資源少。
[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.
