Abstract: 桌面是我們於日常生活中熟悉的空間。以桌面為載體,探討適用於桌面空間之互動技術與人機介面,在人機互動研究中具有令人期待的可能性,並存在許多有趣的挑戰。此篇論文的目的為,以未來日常生活中的互動桌系統為對象,瞭解使用者與之互動時潛在的使用性問題,研發人機互動技術協助改善其使用性,並提升使用者滿意度。
互動桌系統在近年呈現出多樣化的發展。不僅是觸控、手勢、聲控、或實體物件輸入等各式互動介面,研究觸角更延伸至桌面系統之多人協同合作。互動顯示以各種形式進入桌面,如智慧型手機、膝上型電腦、隨身型投影機等。可說是以桌面為中心,儼然已形成一個互動顯示生態系統。此論文將著重於其中兩個課題:多重解析度顯示,以及直接指觸操作。閱讀是在書桌上重要的活動之一。多重解析度顯示能夠呈現一個大範圍的顯示區域,同時在局部區域呈現出精緻的細節。當我們需要一個大尺寸的互動工作桌時,此顯示方式提供了一個相當具成本效益的方法。我們提出的多重解析度顯示技術,在檢視高解析度影像時,能夠在達到更流暢的互動瀏覽經驗。在多重解析度互動顯示系統上,我們進行了一系列的使用性評估研究。該研究成果顯示可動式的高解析度顯示在特定的工作形態下比固定式的高解析度顯示能夠帶來明顯的效益。另一方面,我們著手研究存在虛擬顯示幕上的使用性問題。為了深入了解這個問題,我們發展了在該顯示幕上實現直接指觸操作的互動技術。於前期研究中,我們發現缺乏觸覺回饋造成使用者無法有效地在虛擬顯示幕上執行直接指觸操作。在嘗試加入多種視覺與聽覺之回饋輔助後,研究結果顯示為操作手加上光影效果能夠有效的改善直接指觸操作的表現。
Desktop is common furniture in our daily life. Designing interface between displays and desktops induces great possibilities and challenges in the field of human-computer interaction. The goal of this dissertation is to show how interaction techniques can improve the satisfaction/quality of human-computer interface on interactive desktops of everyday life. Recent progress on interactive desktop systems has shown considerable diversity ranging from touch, gesture, voice, and tangible inputs. Around the desktop, a display ecosystem is beginning to take shape such as incorporating with mobile phones, laptops, and pico-projectors. This dissertation will focus on the topics of multi-resolution display and direct-touch interactions. Reading is one of the most important activities around desktop. Multi-resolution presentation provides a cost-effective and energy-effective way to deliver acute information on a large working surface. The techniques offer a more fluid graphical interaction in examining high-quality images. Empirical data gathered during the course of a multi-faceted user study demonstrates that the steerable focus region system significantly outperforms the fixed focus region system. Direct-touch is intuitive in interactions with interactive surfaces. To understand the challenges in operations of intangible displays, we developed the direct-touch interaction on intangible displays. The experimental results suggest pseudo-shadow and audio feedbacks are effective in improving user performance while reducing their uncertainty.
