The human-computer interaction plays a critical role between the communication of the machine and the human beings. The ability of 3D visualization system to realistically and quickly render the appearance of products or architectures makes it an attractive and affordable solution for product demonstration. Furthermore, the tangible interface of augmented technology, allowing users to interact with products of interest via hand gestures, offers immersive, joyful, and lifelike product interaction experience to users. By integrating the technologies of 3D visualization and augmented reality, this paper proposes a smart, tangible, and gesture-based visualization system for feminine dress-fitting. To evaluate the usability of the proposed system, a field study experimental method is adopted where every participant is asked to experiment with the proposed system first, and fill out a usability questionnaire afterwards. The questionnaire consists of six constructs: effectiveness, ease of use, interactivity, joyfulness, lifelikeness, and satisfaction. The subjects consist of 34 females, with age ranging from 20 to 29 years old. The results of the questionnaire indicate that the subjects show positive attitude toward the proposed system.
