Multimedia augmented reality information system for museum guidance

This paper introduces the design and implementation of an augmented reality-based guidance system used for museum guidance. The objective of this study is to deliver the new museum guidance with intuitive and user-friendly interactions between man and machine based on computer vision technique in ubiquitous computing environment. In our design, a camera is used to capture hand motions and images of a printed guide, which are analyzed instantaneously to parse the designated actions the guidance system promptly responds with. The system can display and illustrate contextual information about 3D models of museum artifacts and multimedia materials to users in real time to compliment the museum experience. Moreover, the performance of the approach we proposed herein has been compared with that of the other alternatives with which the guidance system has also been installed for similar exhibitions. As a result, our proposed approach outperforms the other applications. The advantage of the proposed approach includes the exclusion of common tactile peripheral devices, for example, keyboard and mouse, which accordingly reduces hardware-related costs and reduces the risk of contamination in a public environment.

Glove Based User Interaction Techniques for Augmented Reality in an Outdoor Environment

This paper presents a set of pinch glove-based user interface tools for an outdoor wearable augmented reality computer system. The main form of user interaction is the use of hand and head gestures. We have developed a set of augmented reality information presentation techniques. To support direct manipulation, the following three selection techniques have been implemented: two-handed framing, line of sight and laser beam. A new glove-based text entry mechanism has been developed to support symbolic manipulation. A scenario for a military logistics task is described to illustrate the functionality of this form of interaction.
