“…Horizontally moving vertical stripes to elicit o.k.n. were generated on the cathode ray tube by means of a computer graphical technique (Yasui, Tole & Young, 1977). The stimulus pattern covered + 450 of the subject's visual field in the horizontal plane, and 340 up and 150 down in the vertical plane.…”

SUMMARY1. Smooth pursuit and saccadic components of foveal visual tracking as well as more involuntary ocular movements of optokinetic (o.k.n.) and vestibular nystagmus slow phase components were investigated in man, with particular attention given to their possible input-adaptive or predictive behaviour.2. Each component in question was isolated from the eye movement records through a computer-aided procedure. The frequency response method was used with sinusoidal (predictable) and pseudo-random (unpredictable) stimuli.3. When the target motion was pseudo-random, the frequency response of pursuit eye movements revealed a large phase lead (up to about 900) at low stimulus frequencies. It is possible to interpret this result as a predictive effect, even though the stimulation was pseudo-random and thus 'unpredictable'.4. The pseudo-random-input frequency response intrinsic to the saccadic system was estimated in an indirect way from the pursuit and composite (pursuit + saccade) frequency response data. The result was fitted well by a servo-mechanism model, which has a simple anticipatory mechanism to compensate for the inherent neuromuscular saccadic delay by utilizing the retinal slip velocity signal.5. The o.k.n. slow phase also exhibited a predictive effect with sinusoidal inputs; however, pseudo-random stimuli did not produce such phase lead as found in the pursuit case.6. The vestibular nystagmus slow phase showed no noticeable sign of prediction in the frequency range examined (0 -0 7 Hz), in contrast to the results of the visually driven eye movements (i.e. saccade, pursuit and o.k.n. slow phase) at comparable stimulus frequencies.

The purpose of the References and Reviews Department is to collect and to disseminate rapidly as many publication citations of interest as come to the attention of the editor. Areas of interest cover all aspects of Computer Graphics and Interactive Techniques, particularly the following: man-machine interaction, graphical representation of data, data structures, data base searching and retrieval, computer aided design, graphic control systems, network design, computer art, computer animation, graphic software, graphic hardware, and the areas listed in the taxonomy by the GSPC Subcommittee (see Computer Graphics, 12(December 1978), 40--45).Technical reports, Master's and Ph.D. theses will be included in the list of current literature, provided that copies of these will be generally available, either on request, through interlibrary loan, on microfilm, microfiche or other means. Such references should be submitted to the departmental editor (address see front inside cover).
