Eye control for PTZ cameras in video surveillance

Bartosz Kunka, a PhD student at the Gdańsk University of Technology have employed a remote gaze-tracking system called Cyber-Eye to control PTZ cameras in video surveillance and video-conference systems. The movie prepared for system presentation on Research Challange at SIGGRAPH 2010 in Los Angeles.

Oculis labs Chameleon prevents over shoulder reading

"Two years ago computer security expert Bill Anderson read about scientific research on how the human eye moves as it reads and processes text and images. 'This obscure characteristic... suddenly struck me as (a solution to) a security problem,' says Anderson. With the help of a couple of software developers, Anderson developed a software program called Chameleon that tracks a viewer's gaze patterns and only allows an authorized user to read text on the screen, while everyone else sees gibberish. Chameleon uses gaze-tracking software and camera equipment to track an authorized reader's eyes to show only that one person the correct text. After a 15-second calibration period in which the software learns the viewer's gaze patterns, anyone looking over that user's shoulder sees dummy text that randomly and constantly changes. To tap the broader consumer market, Anderson built a more consumer-friendly version called PrivateEye, which can work with a simple Webcam to blur a user's monitor when he or she turns away. It also detects other faces in the background, and a small video screen pops up to alert the user that someone is looking at the screen. 'There have been inventions in the space of gaze-tracking. There have been inventions in the space of security,' says Anderson. 'But nobody has put the two ideas together, as far as we know.'" (source)
