- MIT researcher Deb Roy wanted to understand how his infant son learned language
- He wired up his house with video cameras to catch 8 to 10 hours of video a day of his son’s life
- He then parsed 90,000 hours of this home video to find out how the word “ga ga” slowly turn into the word “water”
- Additionally, he and his team developed new ways to use motion analysis (space-time worms) to view how and where his son moved throughout the house
