Methods of Investigating Eye Movements

Abstract

A review of a family and the most recent case history in the only male has shown that the cerebellar tumdur was verified for sibling I at the age of 29 years by pathological section and an eye tumour was treated by radon seeds. Sibling II-the cerebellar tumour was verified at operation at the age of 23 years and by pathological section at two subsequent operations. The eye tumour presented a similar pathological appearance. Sibling III had a naevus of the limbus of the left eye, which became less apparent after nine years. Sibling IV: The new case was verified by pathological examination at the age of 28 years and after extensive radiation an-eye tumour, capillary in type, has slightly progressed in four years. Acknowledgment: To Dr. K. W. McKenzie my thanks and congratulations for the surgical care and remarkable results that have meant so much to the members of this family. Dr. Eric Linell was responsible for the excellent pathological reports and photographs. Miss Wishart made coloured drawings, which add much to the written description. Also thanks to the Departments of Surgery, Neuro-Pathology, Veterans' Affairs, Ophthalmology, Art and Photography.

Application of eye-tracking in drivers testing: A review of research

“…In 1931, Earl and Taylor developed 2 devices, called "Ophthalmograph" and "Metronoscope," that enable accurate recording of eye movements, and above all, of saccades and fixations [1]. The 1st "eye-tracker" (a device for recording eye movements) in a form of a helmet equipped with a mini-camera was the work of Hartridge and Thompson (1948) [3]. It was improved by Shackel in 1960 [4], and then in 1962 by Mackworth and Thomas [5].…”

Biometric Measures for Interactive Advertising Research

“…The first nonintrusive eye tracker, using beams of light reflected on the eye and then recorded on film, was used by Guy Thomas Buswell (1920) to study reading and picture viewing; Hartridge and Thompson (1948) then invented the first head-mounted eye tracker. A wide range of eye-trackers now exist, though they mainly represent three categories: invasive, such as a special contact lens with embedded sensors (used in medicine diagnosis and studies of the physiology of eye movements); EOG electrodes placed near the eyes to register variations in the electric field (sensitive to even miniature saccades and capable of working without a light and with eyes closed, as widely used in studies on sleep); and optical eye-trackers, which reflect light, typically infrared, in the eye and measure it with a video camera or some specially designed optical sensor.…”

“…These were related to how easy the information is interpreted [6]. The first head mounted eyetracker was developed by Hartridge and Thompson in 1948 [7].…”
