Abstract
Recent years, interaction design, the art of effectively creating interesting and compelling experiences for users, has become an important issue in the development of digital-multimedia applications. In our previous work, we had developed an interactive visual display system named Magic Crystal Ball (Mac Ball) which allows the users to see a 3D virtual artifact appearing inside a transparent glass ball and to manipulate it with bare hands. In this paper, for the purpose of creating a more intuitive and aesthetic interactive user experience with enjoyment, we redesign the interactive components to improve the accuracy and stability of Mac Ball. In hand motion detection, we construct the Mac Ball coordinate by system calibration to obtain precise 3D directions and distances of hand motions during the interaction process. In touch detection, we integrate strain gauge sensors with a cantilever beam structure into the touch detection module to achieve the better stability of detection. Then, we propose effective and suitable software implementation based on the new interactive components. The details of design and implementation for the interactive components will be discussed in this thesis.
