The touchscreen device is now commonly found in the form of mobile phones, tablet PCs, and other devices. Varied physical and visual experiences can be experienced through touchscreens. This study intended to explore how the physical and visual experiences provided by the touchscreen would affect people through their existing associations of behavior-attitude. Previous studies have found that certain behaviors affect attitudes. In particular, the approach-avoidance behavior has been noted to influence both social and personal attitudes. It was thus deemed necessary to ascertain the approach-avoidance effect exerted by touchscreens on the attitudes of users as the technology is widely used today. Experiment 1 provided an approach-avoidance experience via a touchscreen and demonstrated that touchscreen-based approach-avoidance dragging behavior on the touchscreen can affect a user's preference and purchase intent. It was found that a product that had been approached showed both higher preference and higher purchase intent than a product that had been avoided. Experiment 2 investigated whether a similar effect would occur when only the visual experience of approach-avoidance was provided. The outcome proved that products that had been visually approached had higher scores than products that had been avoided, both in terms of preference and purchase intent. The movement of the arm on the touchscreen (Experiment 1) and the visual perception of the approach-avoidance experience (Experiment 2) were both shown to influence participants' attitudes toward products. The results of this study suggest that the behavior and perception of users may be an important factor in designing touchscreen interfaces for online shopping.

In X-ray projection, Unskilled radiologists become skilled through fail exam. This causes the patient to be exposed to unnecessary radiation. In this study, pre-position unskilled radiologic technologist presented ways to improve clinical proficiency. presented a skull lateral x-ray projection practice method using visual, spatial, and assistive devices. In addition, the accuracy and usefulness of the use of assistive devices were evaluated. When X-ray images were taken based on learning, the rotational spacing, which indicates image distortion, was 7.85 ± 1.45 mm and the tiliting spacing was 4.84 ± 0.5 mm. When practicing using visual aids, the rotational spacing is 4.4 ± 0.76 mm and the inclination spacing is 3.01 ± 0.87 mm. using a spatial compensation device, the rotational spacing is 5.2 ± 0.69 mm and the tiliting spacing is 3.33 ± 0.61 mm. Skull lateral X-ray Image distortion caused by empirical photography practice decreased by 5.4%, but image distortion caused by tilting increased by 1.2%. When practicing using a visual assistive devices, the degree of rotational spacing by 40.1% and the tiliting spacing decreased by 30.7% compared to the empirical x-ray exposure practice. When using spatial assistive devices, the rotation interval was reduced by 41.7% and the tilting interval by 23.7% compared to conventional empirical x-ray exposure practice. Therefore, if an unskilled radiologist practices using visual and spatial aids,the accuracy will be improved in skull lateral x-ray projection.

본 논문에서는 게임 사용자들이 요구하는 게임 경험치에 대하여 제안한다. 게임 경험치는 사용자들이 게임을 처음 접하는 단계에서 게임을 즐기는 동기 부여적인 측면과 게임을 진행함에 따라 게임 내 밸런스를 유지하기 위한 매우 중요한 요소이다. 게임을 즐기는 요소로서 게임의 재미요소에 대한 연구는 다양한 방면으로 진행되어 왔다. 그러나 게임 경험치 획득에 대한 구체적인 연구는 없었다. 게임 사용자들이 요구하는 게임 내 경험치 획득에 관하여 연구하기 위하여 사용자 그룹을 선정하여 사용자들이 각자 자기경험을 바탕으로 캐릭터의 레벨이 상승함에 따라 요구하는 경험치를 시각적으로 확인하면서 구체적인 값을 제시하도록 하였다. 이러한 결과는 향후 게임을 개발하는데 있어 사용자 요구를 반영하여 보다 일반적인 게임 경험치를 부여하는 기준으로 사용될 수 있다.

Information gathered through experience transforms into knowledge and such knowledge becomes a foundation for intuitive decisions. Based on such background, the following study investigates intuitive decision making on basic elements needed for design concepts and visual conceptualizations. The study consist two phases. first, 12 structural elements of a digital camera and relation between each elements were arranged intuitively on a board. Next, sketches were generated with relationship of structural elements in mind. As a result of the study, concept with intuitive decisions effect structural thinking, various developments, specific operation methods , and sketch expressions. However, study also revealed that the freedom of human emotions don't accord with the qualification map.

As the interactive AI speaker becomes popular, voice recognition is regarded as an important vehicle-driver interaction method in case of autonomous driving situation. The purpose of this study is to confirm whether multimodal interaction in which feedback is transmitted by auditory and visual mode of AI characters on screen is more effective in user experience optimization than auditory mode only. We performed the interaction tasks for the music selection and adjustment through the AI speaker while driving to the experiment participant and measured the information and system quality, presence, the perceived usefulness and ease of use, and the continuance intention. As a result of analysis, the multimodal effect of visual characters was not shown in most user experience factors, and the effect was not shown in the intention of continuous use. Rather, it was found that auditory single mode was more effective than multimodal in information quality factor. In the semi-autonomous driving stage, which requires driver 's cognitive effort, multimodal interaction is not effective in optimizing user experience as compared to single mode interaction.

The purpose of this study is to explore physical factor of digital text structure for designing e-Book interface and to develop prototype of e-Book interface by applied these factors. To address this goal, explore factor analysis and confirmatory factor analysis were employed, 237 university students were the participated in this study. According to a result, 29 items for physical feature of digital text structure were developed, 9 factors of digital text structure were also extracted; volume, depth, density, space, layout, format, signal, size, and length. Besides, to identify structure of pre-defined 9 factors, confirmatory factor analysis was conducted. As a result of CFA, the factor structure was supported by all of model fit indices.

Form design for information registration should consider and classify various possible cases and each user case and reflect it in the design. In this paper, I analyzed the visual and emotional factors of information design that elicit positive emotions from the user experience point of view, focusing on the birth certificate of among other public documents issued by the government. In order to derive problems and supplements from the user's overall writing experience point of view, Keller's Motivational Behavior Construction Model was used. The process of writing the birth registration form creates recognition, reasoning, relationship, establishment, achievement, expectation. In order to more actively draw an emotional point of view, it is essential to set of information and to materialize the information experience. It is hoped that this will be a good guideline in the process of presenting a new perspective on information design and improving the experience.

This study suggests multisensory interaction techniques to help visually impaired people appreciate and understand artworks through non-visual senses such as tactile, auditory, and olfactory senses. A user study was conducted on the basis of a qualitative interview about the experience of appreciating artwork through the multisensory interaction system to visually impaired people so as to verify the development of the interaction techniques. The user test shows that the multisensory interactions in artwork generally not only help them appreciate and understand it but also give them satisfaction through artwork appreciation. However, it also indicates that some multisensory interactions caused the visually impaired people confusion and could not be perceived during the appreciation. On the basis of these outcomes, implications in this study are as follows. This study has contributed to providing specific development guidelines and indicators of non-visual multisensory interactions as a technical alternative to improve accessibility to cultural and artistic activities for the visually impaired. Furthermore, this study is expected to contribute to building a technical background, which can provide comprehensive sensory experiences with not only blind people but also non-blind people such as children and the elderly through universal interaction techniques beyond existing visual-oriented fragmentary experience.
