【摘要】：盡管越來越多有高級功能的智能終端出現(xiàn),但是大部分的盲人還在使用落后過時的手機。因為他們更熟悉這些手機的界面布局,手機上的觸摸按鈕也給他們操作手機提供了幫助。帶有觸摸屏的智能終端沒有可觸摸按鈕,信息輸入時需要精確的定位。給盲人操作帶來極大不便,容易使他們在操作過程中迷失。智能終端支持的可訪問方式包括語音輸入,振動、語音輸出反饋,然而對于盲人來說,發(fā)現(xiàn)智能終端上的功能并能有效的輸入仍然是個很大的挑戰(zhàn)。雖然現(xiàn)在的智能終端已經(jīng)支持語音輸入的命令,但是在嘈雜的環(huán)境里,智能終端很難分辨語音命令,因此這時的操作效率低下而且不準確。隨著觸摸屏技術(shù)的不斷發(fā)展,智能終端配備復雜的手勢識別傳感器。智能終端手勢的研究受到更多的關(guān)注,我們也相信通過手勢盲人可以更高效的操作智能終端。目前,在各個平臺上如:iOS平臺、Android平臺等已經(jīng)實現(xiàn)了盲人使用智能終端的手勢操作。但是各個平臺上的手勢不盡相同,部分手勢過于復雜,難以學習與記憶,不利于盲人操作智能終端。現(xiàn)在有更多的公司逐漸重視人文關(guān)懷,他們希望自己的產(chǎn)品能給盲人的生活和學習帶來幫助。因此需要形成一定的手勢操作規(guī)范幫助盲人操作智能終端�；谝陨显蛱岢雒と酥悄芙K端觸摸屏手勢操作的研究。研究內(nèi)容主要包括三點:(1)確定盲人使用智能終端的基本系統(tǒng)手勢需求,這些手勢應該容易學習不會增加盲人的記憶負擔。(2)在需求基礎(chǔ)上設計手勢操作規(guī)范,根據(jù)設計的規(guī)范開發(fā)接口原型,用來連接Android系統(tǒng)與其它應用軟件。(3)進行驗證實驗,驗證手勢操作規(guī)范的易學性及接口原型的實用性。收集實驗過程中的數(shù)據(jù),以進行規(guī)范的修訂和接口原型的改進。研究過程中首先學習并借鑒iOS平臺、Android平臺及以永德軟件為代表的盲人應用軟件。學習它們的手勢操作,根據(jù)這些手勢設計盲人使用智能終端的系統(tǒng)手勢操作規(guī)范。主要通過簡單的點擊,滑屏,搖晃來操作智能終端,手勢操作成功后均以振動的方式提供反饋。根據(jù)設計的手勢操作規(guī)范,開發(fā)手勢操作的接口原型。進行驗證實驗,讓被測試者通過接口原型,使用研究中設計的手勢操作智能終端。實驗的結(jié)果證明了手勢操作規(guī)范的易學性與接口原型的可用性。但仍然有很多不足之處,需要根據(jù)被測試者的反饋,修訂手勢操作規(guī)范,優(yōu)化改進接口原型,為盲人更好的使用智能終端提供幫助。
[Abstract]:Despite the increasing number of smart terminals with advanced features, most blind people are still using outdated mobile phones. Because they are more familiar with the interface layout of these phones, the touch buttons on the phones also help them operate the phones. Intelligent terminals with touch screens do not have touchable buttons, and accurate positioning is required when information is entered. It brings great inconvenience to blind people and makes them lost in the process of operation. The accessible methods supported by intelligent terminals include voice input, vibration, and voice output feedback. However, it is still a challenge for the blind to discover the functions on the intelligent terminal and to be able to input effectively. Although the intelligent terminal has already supported the command of speech input, it is very difficult for the intelligent terminal to distinguish the command of voice in the noisy environment, so the operation is inefficient and inaccurate. With the development of touch screen technology, intelligent terminals are equipped with complex gesture recognition sensors. More attention has been paid to intelligent terminal gestures. We also believe that blind people can operate intelligent terminals more efficiently. At present, on various platforms such as: iOS platform, Android platform and so on have realized the blind to use the intelligent terminal gesture operation. However, the gestures on each platform are different, some of them are too complicated to learn and remember, which is not conducive to the blind to operate intelligent terminals. More companies are increasingly caring for humanity, and they want their products to help blind people live and learn. Therefore, it is necessary to form certain gesture operation norms to help blind people operate intelligent terminals. Based on the above reasons, this paper puts forward the research of the touch screen gesture operation of the intelligent terminal for the blind. The main contents of the study are as follows: (1) to determine the basic system gesture requirements for blind people to use intelligent terminals, which should be easy to learn and not to increase the memory burden of blind people; (2) to design gesture operation specifications on the basis of requirements. An interface prototype is developed according to the designed specification, which is used to connect the Android system with other application software. (3) A validation experiment is carried out to verify the ease of learning of the gesture operation specification and the practicability of the interface prototype. Collect experimental data for specification revision and interface prototyping improvement. In the course of the research, we first learn from the iOS platform, Android platform and the blind application software represented by Yongde software. Learn their gestures and design system gesture codes for blind people using intelligent terminals according to these gestures. Mainly through simple click, slide screen, shake to operate the intelligent terminal, gesture operation is successful in the form of vibration to provide feedback. According to the design of gesture operation specification, the interface prototype of gesture operation is developed. The verification experiment was carried out to let the subjects operate the intelligent terminal using the gesture designed in the research through the interface prototype. The experimental results show that the gesture operation specification is easy to learn and the interface prototype is available. However, there are still many shortcomings. According to the feedback of the subjects, we need to revise the gesture operation specification, optimize the interface prototype, and provide help for the blind to use intelligent terminals better.
