HD Video Recording Glasses (Kickstarter) — as Bryce says, “wearable computing is on the rise. As the price for enabling components drops, always on connectivity in our pockets and purses increases, and access to low cost manufacturing resources and know-how rises we’ll see innovation continue to push into these most personal forms of computing.” (via Bryce Roberts)
Sketching in Food (Chris Heathcote) — a set of taste tests to demonstrate that we’ve been food hacking for a very long time. We started with two chemical coated strips – sodium benzoate, a preservative used in lots of food that a significant percentage of people can taste (interestingly in different ways, sweet, sour and bitter). Secondly was a chemical known as PTC that about 70% of people perceive as bitter, and a smaller number perceiving as really really horribly bitter. This was to show that taste is genetic, and different people perceive the same food differently. He includes pointers to sources for the materials in the taste test.
Investigating Millions of Documents by Visualizing Clusters — recording of talk about our recent work at the AP with the Iraq and Afghanistan war logs.
Managing Crowdsourced Human Computation (Slideshare) — half a six-hour tutorial at WWW2011 on crowdsourcing and human computation. See also the author’s comments. (via Matt Biddulph)
