【摘要】：隨著大屏幕智能設(shè)備的普及和不斷發(fā)展,它的應(yīng)用逐步滲入到我們生活的各個(gè)角落。然而,與之配套的文本輸入系統(tǒng)卻一直沒能得到很好的發(fā)展,一直采用傳統(tǒng)的以五向按鍵作為操作基礎(chǔ)的遙控器設(shè)備來完成文本字符的輸入。該輸入設(shè)備在進(jìn)行字符輸入時(shí)需要不斷地按動(dòng)按鍵來切換不同的字符選擇,輸入速度慢、操作復(fù)雜。如何減少字符輸入時(shí)按鍵按動(dòng)的次數(shù),提高該字符輸入的速度成為大屏幕智能設(shè)備上一個(gè)亟待解決的問題。本文正是在這樣的背景下,設(shè)計(jì)了一款以手勢動(dòng)作作為輸入源的基于加速度計(jì)和陀螺儀傳感器的英文文本輸入系統(tǒng)原型,具體研究內(nèi)容如下:第一、對(duì)現(xiàn)有手勢識(shí)別的方法進(jìn)行了充分調(diào)研,對(duì)系統(tǒng)原型所需手勢識(shí)別方法進(jìn)行了深入分析。第二、對(duì)字符輸入的過程進(jìn)行了全面的分析,根據(jù)完成一個(gè)字符輸入所必須經(jīng)過的步驟設(shè)計(jì)了兩種用于完成輸入任務(wù)的交互手勢。第三、在分析交互手勢運(yùn)動(dòng)特點(diǎn)的基礎(chǔ)上,遵循啟發(fā)用戶,降低用戶學(xué)習(xí)成本原則,設(shè)計(jì)了兩款虛擬鍵盤布局樣式。第四、通過實(shí)驗(yàn)驗(yàn)證了本文所設(shè)計(jì)的英文文本輸入方式在輸入速度上優(yōu)于傳統(tǒng)的遙控器輸入方式,同時(shí),扇形虛擬鍵盤布局方式優(yōu)于圓形虛擬鍵盤布局方式。采用靈活、自由的手勢操作代替?zhèn)鹘y(tǒng)遙控器設(shè)備字符輸入時(shí)的按鍵操作,從本質(zhì)上改變了字符輸入的方式,而且它更加直觀、自然,能有效地降低用戶的學(xué)習(xí)成本。本文的研究內(nèi)容對(duì)新的文本輸入方式的研究有著一定的參考意義。
[Abstract]:With the popularization and development of large-screen intelligent device, its application gradually seeps into every corner of our life. However, the corresponding text input system has not been well developed, and has been using the traditional five-direction key as the operating basis of the remote control device to complete the text character input. The input device needs to press the key constantly to switch different character selection, which makes the input speed slow and the operation complex. How to reduce the number of keystrokes in character input and improve the speed of character input has become an urgent problem in large screen intelligent equipment. In this paper, a prototype of English text input system based on accelerometer and gyroscope sensor is designed based on gesture action as input source. The main contents are as follows: first, The existing gesture recognition methods are fully investigated, and the gesture recognition methods required by the prototype of the system are deeply analyzed. Secondly, the process of character input is analyzed comprehensively, and two kinds of interactive gestures are designed to complete the input task according to the steps that a character input must go through. Thirdly, on the basis of analyzing the characteristics of interactive gesture movement and following the principle of inspiring users and reducing the learning cost of users, two virtual keyboard layout styles are designed. Fourthly, the experiment proves that the English text input mode designed in this paper is superior to the traditional remote controller in input speed, and the sector virtual keyboard layout is better than the circular virtual keyboard layout. The use of flexible and free gesture operation to replace the traditional remote control device character input keystroke operation essentially changes the character input way and it is more intuitive and natural which can effectively reduce the user's learning cost. The research content of this paper has certain reference significance to the research of new text input mode.
