Abstract
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.
