Researchers reveal a mini facial recognition balloon blimp

Researchers have developed a mini autonomous blimp that can detect hands and faces. It consists of a 3-D printed gondola frame and a mini camera attached to a balloon. The researchers say that blimp could be useful when shopping at large stores, as it would be able to interact with humans and guide them to the correct aisle. All the while, the machine gathers information about the operator, such as hesitant glares and eager smiles - with the researchers' goal to better understand how people interact with flying robots. 'Roboticists and psychologists have learned many things about how humans relate to robots on the ground, but we haven't created techniques to study how we react to flying machines,' says Dr Fumin Zhang, the Georgia Tech associate professor leading the blimp project.
