Firefly MV Camera Mimics the Human Eye

The Center for Clinical Neurosciences at the Ludwig-Maximilians University in Munich developed a unique and award-winning camera system called EyeSeeCam that mimics the motion of human eyes in real-time.

The camera system, using a 0.3 MP Firefly MV camera by Point Grey, can point in any direction and is capable of imitating the fastest human eye movements, which can reach speeds of 500 degrees per second. Unrestricted user mobility and field of view as well as the utilization of biological image stabilization reflexes are main benefits of EyeSeeCam.

The EyeSeeCam combines two technologies – an ultra-mobile eye tracker that measures 3D eye position at unprecedented frame rates of up to 600 Hz as well as a 3DOF motion control unit with 3 ultrasound servo motors that steer a head-mounted Firefly MV camera running at 60 fps to the target of gaze. The motion control unit has been developed in collaboration with the Institute of Applied Mechanics at the Technische Universität München, read more on the IEEE Spectrum website. The system precisely reproduces the eye movements using a superfast actuator-driven mechanism with yaw, pitch, and roll rotation, like a human eyeball. When the real eye moves, the robot eye follows suit.


An off-the-shelf notebook records video files with resolutions of up to 752×480 pixels to hard disk. A novel picture-in-picture functionality combines the image of the gaze camera with another image from a wide-angle scene camera. Just as a magnifying lens, this "hybrid perspective" gives the impression of a sharp image at the target of gaze.

Eye tracking systems are used to capture eye movements and gaze behavior in order to diagnose dizziness, vertigo, or eye movement disorders, or - in combination with a wide-angle scene camera - to examine the perception and interaction in natural scenes, with new devices, or with advertisements.
