Imagine having a searchable video recording of everything that happens in every room of your house.


MIT cognitive scientist Deb Roy started the recording when his first child arrived home, and has kept recording for 5.5 years now.


He now has a 200TB archive, with a 70-million-word transcript, and can do a virtual 3D fly through any moment across all rooms. He can view all developmental milestones, from baby’s first steps to the mastery of any spoken word. He can roll back and see what verbal and physical interactions preceded the acquisition of language. He can draw movement traces through the house of all caregivers and their proximity to his son. From these traces, he can see the social hotspots of interaction. See examples below.


“You are looking at a piece of what is by far the largest home video collection ever made.”


His TED Talk went online today. It is one of my favorites.
