Making a circle with his hands and speaking the words "Crab Nebula," Microsoft researcher Hrvoje Benko summoned the image of the interstellar dust cloud in front of him.
Benko was demonstrating how to use an omni-directional projector, one of 13 up-and-coming technologies on display at the Microsoft Research TechFair at the Newseum Wednesday. Hundreds of representatives from businesses and government agencies attended, viewing technologies with applications ranging from detecting robot-generated spamming attacks to text messaging vocally while driving.
