In 2001, Cybernet created NaviGaze, which is capable of tracking a persons
head and detecting eye blinks. The head movements are used to control the
mouse cursor and the eye blinks are used to produce mouse clicks. The system
was designed for use by seriously disabled individuals (who had no motor
control of their hands).

The Eyes Have It
NASA program develops a system that tracks eye movements for cursor control

NASA is exploring new frontiers in accessibility with a program that could
give disabled users line-of-sight control over their computer screens.  

The space agency has provided funding to create a system that tracks head and
eye movements to register cursor movements and clicks. Developers plan to
provide the system free to the public.  

Officials at Goddard Space Flight Center in Greenbelt, Md., have developed
the system under a Small Business Innovation Research contract with Cybernet
Systems Corp. of Ann Arbor, Mich.  

NaviGaze allows people who lack arm or hand mobility to control cursor
movements with simple head movements. It can be customized to support a wide
range of head mobility, the systems developers said.

The Eyes Have It
From: Government Computer News - 08/09/2004 - Vol. 23, No. 22
By: Wilson P. Dizard III

NASA has committed funding to develop a low-cost system that would enable
severely disabled users to control their computers by tracking head and eye
movements. NaviGaze, developed by Goddard Space Flight Center officials in
conjunction with Cybernet Systems under a Small Business Innovation Research
contract, translates the user's eye movements into cursor movements using a
commercial USB camera. Cybernet research engineer Ryan J. O'Grady explains
that NaviGaze's gesture recognition programs "recognize" the image of an
individual user's eye during a two-minute setup session and searches for that
image through the USB-linked camera in later sessions; after the system locks
on to the image, the user can control the on-screen cursor with his head
movements. At the top of the screen is an indicator displaying the status of
the blink control: A single mouse click is colored green, a double click is
colored yellow, and a click and drag function--which the user can implement
by blinking for four seconds--is colored red. NaviGaze can also be used by
people with limited control of eye blinks via its ability to track and
monitor other movements, such as mouth gestures. In addition, the system
allows a different user to control the cursor using a mouse linked to the
Microsoft Windows system. Once the system has been polished, Cybernet
executives plan to make it freely available for download at cybernet.com in
October. Cybernet R&D director Joseph Tesar hopes that NaviGaze can be turned
into a program that permits users to control lights and doors in a house.
