IBM's Watson Helped Design Karolina Kurkova's Light-Up Dress for the Met Gala

At last night's Met Gala, the lavish annual fashion event hosted by Vogue, model Karolina Kurkova wore a dress that was half man-, half machine-made. The "Cognitive Dress"--perhaps one of the least fashion-forward names found on the red carpet--is the product of a partnership between British design studio Marchesa and Watson, IBM's friendly cognitive computer. The gown, a white tulle design embroidered with 150 LED-connected flowers, is an interesting glimpse of how humans and machines can work together to create something that otherwise wouldn't be possible. To design the dress, Marchesa's designers first chose five sentiments they wanted the dress to express: joy, patience, excitement, encouragement, and curiosity. Then they fed two datasets into IBM's Cognitive Color Tool, a program that uses color psychology to match emotion to hues.
