But if you were working with a robot, that glance would be lost on it鈥攜ou鈥檇 have to verbally spell it out.

Szafir videotapes human co-workers while documenting their facial expressions, gestures and changes in tone of voice. He鈥檒l use the data to develop computer models to program more intuitive robots. He鈥檚 also exploring ways to design robots whose movements are less erratic and who are cognizant of personal space.

鈥淭hey can be loud, robotic-looking and hard to predict,鈥� he says. 鈥淧eople find that unsettling.鈥�
