【摘要】:隨著社會的迅速發(fā)展和競爭的愈加激烈,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)時代,智能手機和平板電腦的硬件性能越來越高,而價格卻不斷下降,使得學(xué)習(xí)者可以方便使用智能手機或平板電腦來進行學(xué)習(xí)。移動學(xué)習(xí)正是伴隨這個大背景而發(fā)展起來的一種新型數(shù)字化學(xué)習(xí)方式。毫無疑問,移動學(xué)習(xí)必須基于可用性高的移動學(xué)習(xí)軟件才能得以開展,F(xiàn)有Android屏幕共享應(yīng)用較少,其中功能相對完善的應(yīng)用,一般價格比較昂貴且不開放其實現(xiàn)方式,不利于開展移動學(xué)習(xí)及學(xué)術(shù)交流。另外,這些屏幕共享應(yīng)用并沒有為實施移動學(xué)習(xí)進行額外的優(yōu)化與設(shè)計。本文正是針對以上兩個問題,對支持移動學(xué)習(xí)的Android屏幕共享進行了深入研究。 首先,本文在初步研究移動學(xué)習(xí)及屏幕共享相關(guān)理論基礎(chǔ)上,,進一步分析Android屏幕共享所需的關(guān)鍵技術(shù),并依據(jù)支持移動學(xué)習(xí)的屏幕共享設(shè)計原則確定了屏幕共享實現(xiàn)方案。其次,本文深入研究了屏幕圖像熱點捕捉技術(shù),并提出一種自適應(yīng)屏幕圖像變化方式的熱點捕捉技術(shù),同時利用該技術(shù)對文本屏幕共享性能進行了優(yōu)化。最后,本文實現(xiàn)了支持移動學(xué)習(xí)的Android屏幕共享應(yīng)用,并進行性能測試與分析。 本文所提出自適應(yīng)屏幕變化的熱點捕捉技術(shù),性能優(yōu)秀,是本文的主要創(chuàng)新點。進一步,本文所設(shè)計并實現(xiàn)的Android屏幕共享,非常適合于移動學(xué)習(xí)環(huán)境下使用,功能完善,兼容性高,實施簡單,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.
