요 약 안구 운동은 뇌 활동을 관찰할 수 있는 비침습적이면서 활용도가 높은 지표이다. 이러한 배경으로 최근 안경류 웨어러블 장비가 연구 기관을 중심으로 빠르게 보급되고 있으며 안구 운동에 대한 연구 활동과 관련 산업의 성장을 고도화하고 있다. 우리는 아동용 비디오 시청 환경에서 안구 운동을 연구하였다. 응시 기간에 따른 장기 기억 상관 여부를 확인해 보았지만 유 의성을발견할수없었다. 하지만시청자극을주의상황과중립상황으로나눈후응시기간에따른차이를확인하였을때긴 응시에서는 장기 기억 인출에서 통계적으로 유의미한 차이를 발견할 수 있었지만 짧은 응시에서는 그렇지 못하였다. 이러한 안구 운동의 특징에서 발견되는 장기 기억과 관련된 인지 처리 과정은 평생 학습 기제에서 선택적 주의를 통한 효율성 추구가 제한된인지처리...

We have conducted the first study of sleep in the platypus Ornithorhynchus anatinus. Periods of quiet sleep, characterized by raised arousal thresholds, elevated electroencephalogram amplitude and motor and autonomic quiescence, occupied 6–8 h/day. The platypus also had rapid eye movement sleep as defined by atonia with rapid eye movements, twitching and the electrocardiogram pattern of rapid e...

This work presents a study on the extraction and analysis of a set of 101 categories of eye movement features from three types of eye movement events: fixations, saccades, and post-saccadic oscillations. The eye movements were recorded during a reading task. For the categories of features with multiple instances in a recording we extract corresponding feature subtypes by calculating descriptive...

The use of eye movement recording can be helpful in the design and evaluation of workplaces, products and many other research topics. As long as only parameters related to the movements of the eyes within the head of the subject (e.g. saccades and fixations) are to be used, an automatic evaluation seems to be the standard procedure. However, often these data should be related to the objects the...

The recording and analysis of eye movements are fundamental to a diverse set of research applications, including studies in which reading, visual search, and both overt and covert visuospatial attention are examined. Software tools supplied with commonly available eye-tracking equipment have generally been limited in functionality and nonextensible. Because of this dearth of available software,...

In order to study the vestibular system in different organs of movement as well as their collaboration between working mechanism, this paper designs a model of the common object request broker architecture (CORBA) for the head and eye movement system based on the vestibular function. By analyzing physiological characteristics of the head and eye movement model, and further introducing the struc...

The sleep of 30 children with disorders of growth and development was studied because of the known association between sleep and the secretion of hormones. Thirty three normal children were studied for comparison. The sleep of two consecutive nights was monitored at home using a small portable electroencephalogram and electro-oculogram recorder. Within the normal group there were no significant...

In studies of smooth eye movements, saccades are often detected and removed from eye movement records during analysis. A simple and effective method for saccade detection is described; the method uses jerk (the third derivative of eye position with respect to time).
