Surveillance Applications

In applications where the locations of human subjects are needed, for example, human-computer interface, video conferencing, and security surveillance applications, localizations are often performed using single sensing modalities. These mono localization modalities, such as beamforming microphone array and video-graphical localization techniques, are often prone to errors. In this chapter, a modular multimodal localization framework was constructed by combining multiple mono localization modalities using a Bayesian network. As a case study, a joint audio-video talker localization system for the video conferencing application was presented. Based on the results, the proposed multimodal localization method outperforms localization methods, in terms of accuracy and robustness, when compare with mono modal modalities that rely only on audio or video.

In this chapter, the authors provide evidence for the potential of various Web 2.0 applications in higher education through a review of relevant literature on both emerging educational technologies and social networking. Additionally, the authors report the results and implications of a study exploring faculty awareness of the potential of Web 2.0 technologies (blogs, wikis, social bookmarks, social networks, instant messaging, internet telephony, and audio/video conferencing) to support and supplement classroom instruction in higher education. Also, using the Decomposed Theory of Planned Behavior as the theoretical foundation, the authors discuss factors that influence faculty decisions to adopt specific Web 2.0 technologies. The chapter concludes with a discussion of the implications of the study and recommendations for future research.

ABSTRACT Integration in operation theater (OT) usually refers to systems integration, which means functionally connecting the OT environment. It includes integration of patient information system, audio, video, surgical lights and room lights, building automation (HVAC), medical equipment, telemedicine, videoconferencing, etc. When integrated, all technology can be manipulated from a central command console by single operator. Integration in OT holds the key for effective application of minimally invasive surgery, robotic surgery and functioning of hybrid OT. Apart from the conventional planning team for an OT, bringing on board an IT professional is a must for planning IT requirements. Integration in OT requires 15% more space than the conventional OT in order to accommodate the IT gadgets, i.e. walk-in technology room that would house teleconferencing and A/V equipment, blade-server computers, fiberoptic network electronics, teleconferencing and video conferencing equipment, audio-visual racks, etc. the level of integration can vary within an OT depending upon the user requirement. Space requirement for a general I-OT is about 60 m2, a cardiovascular I-OT or one that includes robotics may come up to 80 m2 or more, and I-OT with in-room imaging equipment requires at least 100 m2. Integration in OT not only increases the efficiency and patient safety in delivery of healthcare but can significantly increase efficiency and effectiveness both in teaching and research.
