Bedford, MA, April 28, 2004--Applied Science Laboratories (ASL) has introduced a lightweight, tether-free, wearable eye-tracking system designed to be worn by an active subject when total freedom of movement is required and when video with cursor overlay is the desired output. The eye-tracking optics are extremely lightweight and unobtrusive, and the recording device is small enough to be worn on a belt.

The device features are intended to enable eye-tracking analysis across a wide range of active-subject applications, particularly in sports, such as golf, baseball, marksmanship, and operation of motor vehicles and aircraft. Eye-tracking systems provide an important design evaluation and research tool for computer displays used in aviation, aerospace, defense and industry. Specific applications include design of simulators, computer displays and control panels used in air traffic facilities, aircraft and cockpits, vehicles and complex manufacturing displays.

Eye-tracking systems also have a wide range of medical research applications and could have significant potential for early detection and treatment of various disorders. The systems are powerful enough to permit eye movement measurement with a subject's eyes closed, which is important in sleep research. Future medical applications could include AIDS and Alzheimer's
research; head injury evaluation; and evaluation and remediation of dyslexia and other reading dysfunctions. Possible educational applications include helping educators to test reading ability and comprehension performance.

The eye image and scene image are interleaved and saved on a DVD/VCR (DVCR) tape to ensure that no resolution is lost. Tape duration is 75 minutes, battery operation, at full charge, is 130 minutes. This tape is then transferred to a PC that separates the images, performs the analysis and creates a scene video with cursor overlay. The sample rate is 25-30Hz.
