Extended User Centered Design (UCD) Process in the Aspect of Human Computer Interaction

摘要

Design methodology of the Human-computer interaction (HCI) ensures stability, efficiency, and usability of the future artifacts. HCI concerned for the development of interaction methods as well as user interfaces. Several methods are used since the term HCI was coined. HCI methodologies are formed into various certain features and the features are based on the user acceptance, usability, and technical issues, indeed each method based on a specific affair. A method or process `User-Centered design' (UCD) is exercising in a broad area of HCI. In spite of existing UCD process significance, in a while, several boundaries and limitations arise during the development of the artifacts. UCD process is not static, and the variations in UCD incorporated into various approaches depending on needs, and task. The principle of UCD process is to involve the user participation in the development to ensure users demand and interests. For the variations of UCD process researchers are developing the model by extending diverse technical and conceptual terms depending on respective activities, therefore occasionally the process draws inappropriate images of the future artifacts, although ISO 9241-210 defined an ideal UCD process guidelines to HCI development. This research analyzed the significance, usability, and the absence of existing UCD process and extended a conceptual term as Elicitation. Respective section illustrated the extended term significance, practice and approaches to HCI design. The key concern is to develop the UCD method in this research, alongside discuss the existing methods limitations and absences for future HCI development.
