3D Photo Browsing for Future Mobile Devices

Abstract [en]

By introducing the interactive 3D photo/video browsing and exploration system, we propose novel approaches for handling the limitations of the current 2D mobile technology from two aspects: interaction design and visualization. Our contributions feature an effective interaction that happens in the 3D space behind the mobile device's camera. 3D motion analysis of the user's gesture captured by the device's camera is performed to facilitate the interaction between users and multimedia collections in various applications. This approach will solve a wide range of problems with the current input facilities such as miniature keyboards, tiny joysticks and 2D touch screens. The suggested interactive technology enables users to control, manipulate, organize, and re-arrange their photo/video collections in 3D space using bare-hand, marker-less gesture. Moreover, with the proposed techniques we aim to visualize the 2D photo collection, in 3D, on normal 2D displays. This process is automatically done by retrieving the 3D structure from single images, finding the stereo/multiple views of a scene or using the geo-tagged meta-data from huge photo collections. By using the design and implementation of the contributions of this work, we aim to achieve the following goals: Solving the limitations of the current 2D interaction facilities by 3D gestural interaction; Increasing the usability of the multimedia applications on mobile devices; Enhancing the quality of user experience with the digital collections.

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.
