Visual object tracking with a $300 drone

Haskins may be good at tracking eyes, but we're following balls (green ones, to be precise). Dramatic reduction in the cost of drone aircraft and digital video cameras, combined with the availability of powerful software platforms like OpenCV (the same technology that won the DARPA Grand Challenge race in 2005), are making this kind of research available to anyone with a few hundred dollars, a decent laptop, and the ability to program in a general-purpose language like Python.

Tobii eye tracker laptop prototype

Salon Science features an article called "New tracking technology knows when, where your eyes look" by Peter Svensson of the Associated Press that describes a laptop prototype by Tobii Technology Inc. Tobii eyetrackers are commonly used in academic research in areas such as psychology, vision, and marketing. For example, at Haskins Laboratories in New Haven, Connecticut, eyetracking is a frequently used methodology in cognitive science research related to reading, attention, and perception. The laptop prototype uses a combination of cameras and infrared light sources to help track gaze and determine where you are looking on the screen.
