In this paper, we analyze the interaction features using eye-tracker and the characteristics of attention concentration of children with intellectual disabilities, and present gamification elements that can be used when designing digital contents for them. For children with quadriplegic cerebral palsy, eye-trackers will increase the accessibility of digital contents. Foreground gamification can be used for selective attention concentration, background gamification and intrinsic motivation to sustain attention concentration, and foreground gamification and extrinsic motivation for mobility.

난독증은 정상적인 지능에도 불구하고 문장을 읽기가 어려운 독서 장애다. 난독증 진단 방법은 ADHD처럼 증상 체크리스트가 없다. 지적장애를 판정할 때 사용하는 웩슬러 지능검사 같은 전 세계인이 사용하는 아주 보편화된 심리검사도 없다. 미국 진단기준의 최신판인 DSM-5에도 어떤 검사를 해서 기준점수 아래여야 진단할 수 있다고 명확히 써놓지 않았다. 본 논문에서는 이를 해결하기 위해 글자, 단어, 문장, 문단의 단위를 설정하여 화면에 출력하고 아이트래커를 활용하여 읽는 사람의 시선 데이터를 수집하여 히트맵으로 분석한다.

Objective : The purpose was the effect of sensory integration therapy combined with an eye tracker on the sensory processing and visual perception of children with developmental disabilities. Methods : It was a single-subject study with a multiple baseline design between subjects, and the intervention applied sensory integration therapy combined with an eye tracker. Visual-motor speed and saccadic eye movements were assessed at each session of baseline and intervention periods. As pre- and post-evaluation, sensory profile, Korean-Developmental Test of Visual Perception and Trail Making Test were conducted. The results of each session evaluation and pre- and post-evaluation researched the effectiveness of the intervention through visual analysis and trend line analysis. Results : As a result of the evaluation for each session, the slope of the trend line for all children in visual-motor speed and saccadic eye movement increased sharply during the intervention compared to the baseline. As a result of the pre- and post-evaluation, the sensory processing of movement, body position, and visual changed from more than that of peers to a level similar to that of peers. In visual perception, all children's ability of Visual Closure increased. As a result of Trail Making Test conducted to confirm the improvement of children's visual tracking and visual-motor abilities, all children showed a decrease in performance time after the test compared to before. Conclusion : It was confirmed that sensory integration therapy combined with an eye tracker for developmental disabilities has effect on sensory processing and visual perception. It is expected to play an important role clinically as it can stimulate children's interest and motivation in line with recent technological improvements and the spread of smart devices.

The cognitive ability of humans depends much on the vision. 'Vision' refers to the sense that receives stimulus of light through eyes. 'Gaze' refers to a function of a straight line that connects the central point of the pupil and a viewpoint in the external world, and, in general, it means a straight line that connects an object that is viewed and the eyes. There are active studies on the gaze in various academic circles including 'psychology' and 'cognitive linguistics.' As a method to objectively analyze the gaze, studies on 'eye tracking' are revitalized. A device for studies on eye tracking is an 'eye tracker.' As the fields of the study expand from development and analysis of Web pages to analysis of stores, methods of traffic signal processing, transport equipment, analysis of user experiences on image contents, and marketing analysis, there occurs a greater demand for a glasses eye-tracking than that for a fixed eye tracker. This study identifies the overview and characteristics of eye tracking and presents a way for spreading studies on eye tracking.

프로그래머들이 코딩을 할 때 발생하는 빈번한 실수는 많은 시간적 비용을 낭비할 수 있고 작은 실수가 전체 코드에 치명적인 에러를 유발하기도 한다. 이러한 문제점은 프로그래머들이 코드를 작성할 때 전체적인 알고리즘을 얼마나 잘 이해하는지와 이전 코드에 대한 이해력과 연관이 있다. 만약 코드에 대한 이해가 어렵다면 정교하고 간결한 코드를 작성하는데 무리가 있을 것이다. 기존 코드에 대한 난이도를 평가하는 방법은 자가평가 등을 통해 이루어져 왔다. 사람 내부 변화를 직접 측정하면 더 객관적인 평가가 가능할 것이다. 본 논문은 이런 문제들을 해결하고자 동공 추적이 가능한 아이트래커와 뇌파 측정이 가능한 EEG장비를 이용하여 습득한 생체 데이터를 통해 프로그래머들의 프로그램 난이도 예측 모델을 개발하였다.

Consumers tend to feel concern about disclosure of personal information and, at the same time, to avoid inconvenience of procedural complexity caused by the privacy protections. The purpose of current paper is to investigate relationships between opt-in procedural complexity and shopping behavior using smart phones, moderating by the amount of visual attentions using eyetrackers. Therefore, we created a virtual mobile Web-site in which the complexity of opt-in procedures in our experiment is manipulated and measured. Also, we measured the dwell-time of area of interest using SMI-RED 250 instrument for tracking the real eye movement. Results indicated that the levels of procedural complexity are related to repurchase, indicating a moderating effect of the amount of visual attentions. Finally, we discussed several theoretical and practical implications of management for mobile commerce.

As measuring visual behavior by utilize eye-tracker, this study examines whether consumer concentrates on visual attention with certain object and measures visual behavior with fixation number, fixation duration, the first fixation, which are visual attention pattern of consumer about Mannequin, hanger, shelve as props of display advertising effect on clothing store. It has experimental purpose to recognize relationships in terms of regardless, appropriateness, purchase intention. During display of clothing store, first experimental consequence to measure visual behavior on consumer did appear to allocate more cautions than other props. Second, in terms of relationships with regardless, appropriateness, purchase intention from consumer, each fixation pattern about consumer's fixation number, fixation duration, the first fixation was confirmed that there is meaningful correlation with each other. Accordingly, as advertising effect of mannequin makes consumer to concentrate more visually cautious, it is translated that high favor about display product with mannequin has positive role on purchase intention. Also, there is a purpose that higher feasibility on study result provides practical point on clothing store's display marketing strategy of corporation.

Consumers possess their own psychological distance towards products. Based on the construal-level theory, this study aims to analyze which type of advertising appeal is more effective according to psychological distance. Also this study conducts neurophysiology experiment through eye-tracker. By using eye-tracking methods, participants' responses to products was measured and analyzed accordingly. Results revealed that consumers prefer rational appeals when the psychological distance is perceived near, while emotional appeals are preferred when the psychological distance is perceived far. In addition, eye movements measured in Visit Count(VC), Fixation Count(FC), and Total Fixation Duration(TFD) showed significant difference when participants are viewing preferred and non-preferred appeals.
