The Mobile Eye is a truly tetherless eyetracking system for use when total freedom of movement is required and video with overlayed cursor is the desired output. This system is designed to be easily worn by an active subject. The eye tracking optics are extremely lightweight and unobtrusive and the recording device is small enough to be worn on a belt.

The eye image and scene image are interleaved and saved on a DVCR tape. This method insures no loss of resolution, Tape duration is 75 minutes, battery operation, at full charge, is 130 minutes. This tape is then transferred to an included PC that separates the images, does the analysis and creates a scene video with cursor overlay. Sample rate is 25/30Hz..
The Mobile Eye comes as a complete system with all necessary hardware and software. The portable DVCR can be connected directly to the PC for real time tracking in a laboratory setting.

	SYSTEM COMPONENTS - Head mounted optics (76g) - Color scene camera - Modified DVCR recorder - Eye Vision Software - PC Pentium 4, 2.8GHz processor
SYSTEM OUTPUTS - Recordable video with moving cursor - Data log file (ASCII data file) - x and y coordinates - pupil radius, in eye image pixels - eye direction with respect to the scene image - mouse cursor position with respect to the scene image
