The Challenge of Education Today • Access to quality education • Pakistan: • 46.7million illiterate adults • Potential vs. Opportunity • Distance learning – empower capable students to realize their potential
Distance Learning • Different approaches to DL • Classroom environment ? • The Power of Video • Recording Videos of Lectures • Fixed Cameras • Hiring Direction Crew • Virtual University (Studio Recording) • Solution?
Automated Video Recording • Manual Crew can • See the lecturer • Pan, Tilt, Zoom the cameras • Discern who is talking • Aesthetic sense • Have to automate all of this!
Eyes • Why lecturers can be tracked? • Computer Vision • Problems in Tracking • Our Innovation
Vision Algorithms Motion Histograms Color Tracking – MeanShift (Comanicui ’99)
Ears • Sound Source Localization • Microphone Arrays • Hack to detect sound direction (hardware interface) • Our Innovation
Making a good video • Direction Sense • Camera Switching • Camera PTZ • Object of Focus • Our Innovation • Programmable Stuff • Movement • Object of focus = tracking + SSL

Design • Modularity – Plug ability - API’s • Customizability (direction scripts) • Extensibility - Build on top of the system (web service) • Mobile devices, communities, collaborative learning, indexing
How it will work • Buy AVRiL System • Around $4000 per auditorium • For 50 auditoriums, less than 10% of the annual cost of a DL program • Auditorium Setup • Direction Script customization (if any) • Select Options, record lecture • Uploads automatically
