Abstract [en]

This paper introduces a novel vision-based approach for realistic interaction between user and display's content. An extremely accurate motion capture system is proposed to measure and track the user's head motion in 3D space. Video frames captured by the low-cost head-mounted camera are processed to retrieve the 3D motion parameters. The retrieved information facilitates the real-time 3D interaction. This technology turns any 2D screen to interactive 3D display, enabling users to control and manipulate the content as a digital window. The proposed system is tested and verified on a huge wall-sized 4K screen.

Abstract [en]

The rapid development of mobile devices during the recent decade has been greatly driven by interaction and visualization technologies. Although touchscreens have signicantly enhanced the interaction technology, it is predictable that with the future mobile devices, e.g., augmentedreality glasses and smart watches, users will demand more intuitive in-puts such as free-hand interaction in 3D space. Specically, for manipulation of the digital content in augmented environments, 3D hand/body gestures will be extremely required. Therefore, 3D gesture recognition and tracking are highly desired features for interaction design in future smart environments. Due to the complexity of the hand/body motions, and limitations of mobile devices in expensive computations, 3D gesture analysis is still an extremely diffcult problem to solve.

This thesis aims to introduce new concepts, theories and technologies for natural and intuitive interaction in future augmented environments. Contributions of this thesis support the concept of bare-hand 3D gestural interaction and interactive visualization on future smart devices. The introduced technical solutions enable an e ective interaction in the 3D space around the smart device. High accuracy and robust 3D motion analysis of the hand/body gestures is performed to facilitate the 3D interaction in various application scenarios. The proposed technologies enable users to control, manipulate, and organize the digital content in 3D space.
