Intro:
The Health Services Virtual Organisation (HSVO) project is a research platform for the experimental development of shared Information and Communication Technologies (ICT) for health services. In the context of the Network-Enabled Platforms, the project offers support to distributed communities of learners and health-care practitioners. One edge device includes an array of overhead cameras intended to give remote viewers the opportunity to see classroom demonstrations from a variety of angles and without being obstructed by physical objects such as tools and the instructor.
Challenge:
Develop a client application to control the view of multiple simultaneous streaming video feeds from a remote array of cameras.
Work:
I developed several Flash-based prototypes that allowed the user to change which camera stream appeared in the main view from a selection of up to 20 different camera feeds including an overhead feed. The system also allowed the instructor to set a recommended feed, enabling the user’s view to follow the recommendations of the instructor. A final prototype was built that allowed the user to select any angle of view, send the view information to a 3D digital image stitching and rendering server developed by other researchers, and display the resulting, reconstructed feed which enabled the user to see the demonstration from any of 360 degrees.
