We make innovative use of computer vision technologies to create effective classroom environment where student from remote locations can attend classes live and get an experience that matches that of student's physically present.
We present a new category of remote teaching environment representations which focus on preserving spatial and temporal correlation amongst the knowledge sources in a classroom. This is done by blending disparate knowledge sources into visually unified multi-layered representations.

Stage 3: Proof of Concept
We have implemented and tested prototypes effective multimedia classroom representations that provide a remote student in the eLearning system with a view that preserves spatio-temporal coherence of classroom elements as in a traditional classroom.

Live eLearning systems present multimedia elements constituting the teaching environment, i.e, 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 this gives a clear view, it breaks any spatial connection between teacher’s gestures and screen content and causes split attention. The teacher too is confined in his/her physical movement.
We introduce new multimedia based representations that circumvent shortcomings of current approaches and provide a spatially coherent view as in a real world classroom scenario. We extensively make use of computer vision techniques for perspective alignment and real-time blending of video elements. A user study with 50 participants showed that our representations enhanced the classroom experience significantly as compared to the representations provided by the state of the art eLearning tools.
We aim to provide an effective teaching environment representation to the remote students so that they do not fall short in their classroom experience as compared to the students physically present in the class. Moreover, the teacher is also not hassled with the requirements of being in a fixed location to operate the elearning tool. The teacher can freely move about the teaching aids and use natural gestures which are essential in creating an engaging teaching environment.
Mission and Vision
We aim to make the process of attending live lectures using eLearning an engaging experience for both the teacher and remote students. This will create an engaging environment similar to that in a traditional environment and enhance the adoption of the much required live eLearning by remote participants.
The innovation maintains the coherence between classroom elements. This gives the students an engaging view, where they can easily correlate the teacher's gestures and the content. They are also not affected by split attention due to different forms of content on different screens or windows in front of them. The teacher is also free to move about the teaching aids as in a traditional classroom. The present eLearning solutions have not provided such facilities, which makes the remote participants lose their interest in a short span of time.
Planned Goals and Milestones
The digital representations can be enhanced with Augmented Reality and Virtual Reality techniques to create an even better and immersive classroom environment. 3D teaching aids such as demo objects can be effectively recreated and presented at a remote location. In a live scenario, it provides scope for better collaboration of remote participants.
