  For the recent years, the Taiwan government has been investing in National e-Learning and Digital Archives Program constructively, it makes Digital Content become rising and flourishing and inject a new tidal current of medium into Taiwan’s culture, especially in Human-Computer Interaction (HCI) is one of the key projects. The purpose of the study is to investigate and explore the Taiwan research work of academic HCI fields from 1983-2010. This study used the "Taiwan Digital Library of Theses and Dissertations" as inspection tool, content analyses the papers that titled with "Human-Computer Interaction" 219 papers were adapted from 1983 and 2010. Four findings were concluded, the result of this research will offer the trend of HCI as the result for the reference of the further study.

  This study presents a real time effective human emulation vision tracking system, which is built up by two webcams and can detect objects in a 3-D space. Because of our programming in this software program, it becomes suitable for teaching and research. In this paper, we set up two webcams by an optical parallel method and deliver images to PC by a USB (universal serial bus) interface. The computer carrying out the image processing using an effective tracking rule to monitor and fast lock the object. Besides, this close-loop system contains two servo motors that control the webcams platform to pitch and yaw target centered in the monitoring image. It can measure the depth of the objects from two webcams by trigonometric function relationship. Finally, we make a virtual environment to verify the capability of this tracking system.
