Abstract Multimedia communication issues are a common occurrence during e-Learning sessions. The issues are not only due to human errors but also due equipment, bandwidth, server and network problems. As our Smart classroom e-Learning system uses many audio/video and display equipment to achieve multi-perspective gaze aligned immersive experience [1, 2], there are many chances of communication errors due to equipment and setup failures. Since a problem might occur due to a failure at any of the ...

Live eLearning systems present multimedia elements constituting the teaching environment, such as - teacher, teaching aids, in various ways creating virtual representations. Often, teacher’s video and screencast of the teaching material are streamed and displayed as mutually exclusive disconnected entities. Though the existing eLearning systems give a clear view of the screen and the instructor delivering the lecture, they break the spatial connection between teacher’s gestures and content on th...

Current live eLearning systems enable remote students to view the teaching environment comprising of several information sources such as the teacher and the teaching aids. These information sources are presented as individual video and audio elements. As a result, spatial connections between these elements, such as the teacher using hand gestures to point to an area on the screen, become meaningless at the remote location. Moreover, the remote students are required to divide their attention betw...

Open image in new window Landslides are the third largest disasters worldwide. In order to save innocent lives and property damage, a system for understanding, assessment and early warning of the landslides is highly necessary. In this work, we have designed and developed an integrated wireless sensor network system for real-time monitoring and early warning of landslides. This paper will discuss the detailed requirements and design criteria considered in the design and development of the Intell...

Open image in new window Landslide prone areas are mostly in remote regions, with very limited network connectivity. Hence it is very challenging to develop a continuous monitoring system, which can deliver early warning of landslides. For developing most appropriate communication architecture we need to consider the following factors that could deliver long term monitoring and real-time early warning of landslides. The factors are: (1) frequency of data collection from spatially distributed het...

Using wireless networks to connect and communicate between geological sensors is a more scalable and suitable way for designing landslide monitoring and warning system for larger areas spanning many acres. Added to this, if the system has the capability to function in solar power, then it becomes autonomous system with self-organizing and self-healing networks. But high terrain, steep slopes, dense vegetation and lack of light during monsoon season to generate solar power pose serious challenges...

eLearning systems have become essential in enabling lectures from experts accessible to masses spread across distant geographic location. The digital representation of different components in the instructor’s environment, such as the presentation screen and the instructor’s video, in a remote location is often spatially disconnected. This results in missing out spatially related gestural cues such as pointing at the screen by the instructor. This paper discusses a method of creating a spatially ...

Building and deploying software for testing and bug fixing happens quite frequently in software development life cycle. Commonly the client-server software needs just one client machine and one server machine to be redeployed before every testing cycle begins. Our Smart classroom [1, 2] e-Learning system requires 3 computers for a given classroom to capture and stream HD video from 5 video cameras placed at different angles or perspectives. It is done to achieve gaze alignment across all the rem...
