【摘要】:在人機(jī)交互領(lǐng)域,以用戶為中心的設(shè)計(jì)理念開始深入人心,人機(jī)交互的高效性和自然性也越來越受到重視。傳統(tǒng)的基于鍵盤/鼠標(biāo)的窄寬帶輸入方式越來越無法滿足人們的需求。基于視線追蹤技術(shù)的眼控交互方式由于其自然性和直觀性,越來越受到研究人員的青睞。本研究在前人研究的基礎(chǔ)上進(jìn)一步探討注視時(shí)間因素對(duì)眼控交互方式的影響,即尋求“米達(dá)斯接觸”問題的解決方案。本研究還提出眼控-手控這一新的雙通道交互方式,并對(duì)比分析手控、眼控和移動(dòng)、點(diǎn)擊兩兩組合條件下四種交互方式的操作績效,比較各種交互方式的操作特點(diǎn)和適用范圍,以便為推廣到實(shí)際應(yīng)用中去提供參考依據(jù)。本研究包括兩個(gè)部分:研究一為不同注視時(shí)間對(duì)眼控點(diǎn)擊績效的影響研究,包括兩個(gè)實(shí)驗(yàn):實(shí)驗(yàn)一研究不同注視時(shí)間對(duì)眼控移動(dòng)-眼控點(diǎn)擊交互方式的影響,實(shí)驗(yàn)二研究不同注視時(shí)間對(duì)手控移動(dòng)-眼控點(diǎn)擊交互方式的影響,分別獲取在眼控移動(dòng)-眼控點(diǎn)擊與手控移動(dòng)-眼控點(diǎn)擊兩種交互方式下最適宜的注視時(shí)間參數(shù)推薦值;研究二為眼控、手控以及眼手結(jié)合控制方式對(duì)輸入績效的影響研究,在研究一獲取最佳注視時(shí)間參數(shù)值的基礎(chǔ)上,驗(yàn)證手控移動(dòng)-眼控點(diǎn)擊和眼控移動(dòng)-眼控點(diǎn)擊交互方式的有效性,探索分析手控、眼控和移動(dòng)、點(diǎn)擊兩兩組合條件下四種交互方式的操作特點(diǎn)和適用范圍,為今后該類交互方式的實(shí)際應(yīng)用提供參考依據(jù)。本研究得出以下主要結(jié)論:(1)在眼控移動(dòng)-眼控點(diǎn)擊交互方式下,推薦采用700ms作為注視觸發(fā)時(shí)間。(2)在手控移動(dòng)-眼控點(diǎn)擊交互方式下,推薦采用200ms作為注視觸發(fā)時(shí)間。(3)基于研究一的注視時(shí)間參數(shù)推薦值,手控移動(dòng)-眼控點(diǎn)擊和眼控移動(dòng)-手控點(diǎn)擊的雙通道交互方式以及眼控移動(dòng)-眼控點(diǎn)擊的單通道交互方式均能有效完成虛擬鍵盤字母輸入任務(wù)。(4)不同的交互方式有不同的操作特點(diǎn)和適用范圍,眼控移動(dòng)-眼控點(diǎn)擊交互方式完全脫離雙手,應(yīng)用范圍最廣,但任務(wù)完成率相對(duì)最低(93.69%),易學(xué)性較差;手控移動(dòng)-眼控點(diǎn)擊交互方式任務(wù)完成率相對(duì)較高,能有效控制誤擊,但需要用手控制鼠標(biāo)移動(dòng),可以考慮設(shè)計(jì)特殊的鼠標(biāo)來配合眼控操作,如ThinkPad中的TrackPoint一樣;眼控移動(dòng)-手控點(diǎn)擊交互方式任務(wù)完成率處于中等水平,眼控移動(dòng)可以配合手指或腳趾等部位進(jìn)行點(diǎn)擊操作,但手控點(diǎn)擊瞬間出現(xiàn)視線跳出的問題還需進(jìn)一步研究解決。本研究進(jìn)一步研究了“米達(dá)斯接觸”問題的解決方案,提出了眼控點(diǎn)擊的最佳注視時(shí)間推薦值;本研究還提出了眼控與手控相結(jié)合的雙通道交互方式,并對(duì)比分析了各種交互方式的操作特點(diǎn)和適用范圍,為推廣到實(shí)際應(yīng)用中去提供了參考依據(jù)。
[Abstract]:In the field of human-computer interaction, the user-centered design concept is becoming more and more popular, and more and more attention is paid to the efficiency and naturalness of human-computer interaction.The traditional narrow broadband input based on keyboard / mouse can not meet the needs of people more and more.Eye control interaction based on line of sight tracking technology is more and more popular because of its naturalness and intuitiveness.On the basis of previous studies, this study further explored the effect of fixation time on eye control interaction, that is, to find a solution to the problem of "Midas contact".This study also proposed a new two-channel interaction mode, eye control and manual control, and compared the operation performance of four kinds of interaction modes under the condition of manual control, eye control and movement, click on the combination of two and two, and compared the operation characteristics and applicable scope of various interaction modes.In order to extend to the actual application to provide a reference basis.This study includes two parts: one is the effect of different fixation time on eye control click performance, including two experiments: one is to study the effect of different fixation time on eye control movement-eye control click interaction.In experiment 2, we studied the effect of different fixation time on the interactive mode of hand-controlled moving-eye click, and obtained the most suitable fixation time parameters under two kinds of interaction modes: eye-controlled moving-eye click and hand-controlled moving-eye click.The second is the effect of eye control, hand control and eye-hand control on input performance.To verify the effectiveness of manual movement-eye control click and eye control moving-eye click interaction, explore and analyze the operating characteristics and applicable range of the four interactive modes under the condition of manual control, eye control and movement, and click on the two combinations.It provides a reference for the practical application of this kind of interaction mode in the future.The main conclusions of this study are as follows: (1) under the eye control movement-eye control click interaction mode, 700ms is recommended as the fixation trigger time.200ms is recommended as the fixation trigger time.The two-channel interaction mode of manual movement-eye control click and eye control moving-hand-click and the single channel interaction mode of eye control mobile eye control click can effectively complete the virtual keyboard letter input task.Have different operating characteristics and scope of application,Eye control movement-eye control click interaction is completely separated from both hands and has the widest range of application, but the task completion rate is relatively low and the ease of learning is poor, and the task completion rate of the hand-controlled mobile eye click interaction mode is relatively high, which can effectively control the mishit.But when you need to control mouse movement by hand, you can consider designing a special mouse to cooperate with eye control, such as TrackPoint in ThinkPad.Eye control movement can be combined with fingers or toes to click, but the problem of sight jump out of sight at the moment of manual click still needs to be further studied and solved.In this study, the solution to the problem of "Midas contact" is further studied, and the best fixation time recommended by eye control click is proposed, and a two-channel interaction mode combining eye control with manual control is also proposed in this study.The operational characteristics and application scope of various interactive modes are compared and analyzed, which provides a reference for the practical application.
