During infancy, a baby's brain maps a mother's moving lips to the sound of her voice with the superior colliculus portion of the brain, which associates external direction with an internal visual reference guide. Researchers at the University of Illinois are using that idea for development of a new self-aiming camera that could help the military distinguish a flock of geese from a fleet of MiGs. "The superior colliculus serves as the visual reflex center of the brain," says Sylvian Ray, a UI professor of computer science. "It is the primary agent for deciding which direction to turn the head in response to sensory stimuli," he says. The system includes microphones and two cameras. As the camera detects motion by comparing successive frames, the system monitors audio signals from the omni-directional microphones. Sound location algorithms analyze the sound and send information to a neural network. A second camera equipped with a long-range lens determines the position of the target. Ray says the combination of sight and sound offers a stronger stimulus than each individually. For more information, go to www.uiuc.edu.
The 100% solar-powered airplane Solar Impulse 2 is prepping for its upcoming flight, becoming the first plane to fly around the world without using fuel. It's able to do so because of above-average performance by all of the technologies that go into it, especially materials.
With major product releases coming from big names like Sony, Microsoft, and Samsung, and big investments by companies like Facebook, 2015 could be the year that virtual reality (VR) and augmented reality (AR) finally pop. Here's take a look back at some of the technologies that got us here (for better and worse).
Good engineering designs are those that work in the real world; bad designs are those that don’t. If we agree to set our egos aside and let the real world be our guide, we can resolve nearly any disagreement.
