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!

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
