Panoramic video in video-mediated education

This paper discusses the use of panoramic video and its benefits in video mediated education. A panoramic view is generated by covering the blackboard by two or more cameras and then stitching the captured videos together. This paper describes the properties and advantages of multi-camera, panoramic video compared to single-camera approaches. One important difference between panoramic video and regular video is that the former has a wider field of view (FOV). As a result, the blackboard covers a larger part of the video screen and the information density is increased. Most importantly, the size of the letters written on the blackboard is enlarged, which improves the student’s ability to clearly read what is written on the blackboard. The panoramic view also allows students to focus their attention on different parts of the blackboard in the same way they would be able to in the classroom. This paper also discussed the results from a study among students where a panoramic view was tested against single-camera views. The study indicates that the students preferred the panoramic view. The students also suggested improvements to could make panoramic video even more beneficial.
