In the recent years, with a purpose to provide visual and psychological stability to patients and hospital users, Affordance design theory based on perceptual psychological thought has been applied as hospital design. In the past, hospital service design was focused on but Affordance design theory focuses on the patients' experience and methodological research on . The characteristics of the application of Affordance design in the case of patients' experience and service point is as follows:- Firstly, Affordance design is applied when the objective of the patient's experience and the functionality of the object are combined. In other words, affordance design is a condition that arises when encounter between service contact point and patients' experience takes place. Secondly, In the field of Hospital service design, Affordance concepts in and its application can be divided on the functions of experience, cognition and sense following the application of Affordance concepts in Hospital service design. Thirdly, Affordance design method sets meaning of the action received through information provided by morphological features. The condition and surrounding has to be designed in a way that it can induce active behavior of the patient. This study has significance as it has been studied from the perspectives of Affordance theory of design psychology in addition to the physical environment of the hospital, the point of interaction between the hospital and patient, along with the elements of experience design. This study proposes the necessity of analytical study in the field of service design implementation considering various stakeholders in the service contact points of small and medium hospitals in Korea. Furthermore, study of the application of Affordance design can be complemented by reflecting the size of hospitals, the characteristics of specialties, and the specific service environment of each hospital can also be conducted.

지난 몇 년 동안 인간과 컴퓨터의 상호 작용(Human Computer Interaction: HCI)에서 사용성(Usability)은 중요한 연구 주제가 되어 왔다. 하지만, 최근 컴퓨터 게임과 같은 유희적인 시스템이 발전하면서, 사용자들의 경험은 유용성과 사용성이 아닌 재미(Fun)와 같은 유희적인 요소들에 초점을 맞추게 되었다. 하지만, 인간과 컴퓨터의 상호작용을 통해서 사용자가 얻는 재미와 재미있는 경험에 대한 연구는 매우 부족한 실정이다. 따라서 본 연구는 컴퓨터 와 같은 디지털 기기를 사용함으로서 사용자가 얻는 재미와 재미있는 경험에 대하여 개념적으로 고찰하고자 하였다. 기존 문헌 조사를 본 연구는 "재미란, 유희 충동에 의해서 놀이 활동을 함으로써 얻을 수 있는 긍정적인 심리 에너지이다" 라는 정의를 내릴 수 있었다. 또한, 본 연구는 "활동 자체를 질서 없이 자유롭게 즐기며, 흥겨움을 느끼는" 재미있는 경험의 내용을 기반으로, 재미있는 경험을 제공하기 위해서 유희적인 시스템이 갖추어야 할 세 가지 요소로서 "상징, 생생함, 새로움"을 제시하였다.

According to the increase of rural experience, that is important in satisfying needs of green tourism and vitalizing rural economy to use closed school in rural area as experience facility. For using closed school as experience facility, political and institutional assistants are needed in effective equipments and stable operation based on multi-perspective approach and analysis. In this study, we try to evaluate green-tourism accessibility of rural experience facility remodeled from closed school considering regional population and spatial characteristics. In evaluating process, gravity potential model are adapted with considering group size of customer and distance-friction coefficient. Distance-friction coefficient is a function of user restriction which depend on possible activity in each experience facility. Green tourism accessibility of experience facility is calculated with summation of accessibility to each region, and we analyzed it as a group by closed school type and location with application in Chungcheongnam-do. We found a correlation between green tourism accessibility of rural closed school and their income.

The strategy that using data collection from Netflix uses for its services is different from traditional human interaction and the communication, and it is represented by the systematic algorithm that rooted from intelligent information system based on the human interaction and communication. These characteristics allowed the study to reflect the influence of 'Asset specificity' which affects the continuous consumption of the media services of Netflix users through economic psychological analysis based on transactional cost economics. The result from the survey on actual Netflix users, three types of specificity (Space specificity, time specificity, relational specificity) reduced perceived searching cost whereas perceived instrumentality has increased, eventually reinforces the commitment to the service. This implies that the service characteristics of Netflix, trying to communicate with the individuals based on intelligent information system are distinct from the existing platform services and it gives the significance of work very effective for user's continuous consumption of the media services.

The distribution of popular videos incurs a large amount of traffic at the base stations (BS) of networks. Device-to-multi-device (D2MD) communication has emerged an efficient radio access technology for offloading BS traffic in recent years. However, traditional studies have focused on synchronous user requests whereas asynchronous user requests are more common. Hence, offloading BS traffic in case of asynchronous user requests while considering their time-varying characteristics and the quality of experience (QoE) of video request users (VRUs) is a pressing problem. This paper uses social stability (SS) and video loading duration (VLD)-tolerant property to group VRUs and seed users (SUs) to offload BS traffic. We define the average amount of data transmission (AADT) to measure the network's capacity for offloading BS traffic. Based on this, we formulate a time-varying bipartite graph matching optimization problem. We decouple the problem into two subproblems which can be solved separately in terms of time and space. Then, we propose the socially aware D2MD user selection (SA-D2MD-S) algorithm based on finite horizon optimal stopping theory, and propose the SA-D2MD user matching (SA-D2MD-M) algorithm to solve the two subproblems. The results of simulations show that our algorithms outperform prevalent algorithms.

최근 출시된 AI스피커들은 사용자와의 인터랙션에 있어 주로 음성으로 상호작용하면서 상태 표시LED를 통해 단순하고 정형화된 시각 피드백을 하는 패턴을 보이고 있다. 이는 스피커라는 제품 특성상 인터랙션의 제약이 많기 때문이기도 하지만 이러한 시각적 피드백마저 제품마다 통일되어 있지 않아 사용자에게 일관된 경험을 주지 못하고 있는 상황이다. LED 표시등으로 표현할 수 있는 시각 요소를 극대화하여 색과 추상적 움직임을 통해 음성 피드백을 보조한다면 사용자에게 기능성의 충족을 넘어 감성적 만족까지 포함하는 확장된 사용 경험을 제공할 수 있을 것이다. 본 연구에서는 기존 AI스피커들의 인터랙션 방식 분석 후, 시각 피드백 효과 확장을 위해 색채 커뮤니케이션 이론에 대해 고찰하고, 색채만으로 감성적 경험을 극대화한 미술 장르인 색면추상의 의미와 표현 기법을 조사하였다. 이를 통해 LED를 이용하여 커뮤니케이션 상태를 피드백하는 방식을 디자인함으로써 AI스피커의 시각 커뮤니케이션 기능성을 확장하고자 하였다.

The goal of this study was to develop a haptic communication system that can convey the tactile sensation of fashion materials in a virtual environment. In addition, the effectiveness and how realistically the virtual fabric image of this system delivers the tactile sensation of actual fabric was verified. First, a literature review was conducted through which the tactile attributes of fashion materials were defined that would be implemented in the haptic communication system. Then, a questionnaire for evaluating the tactile attributes of fashion materials was developed. Next, a haptic communication system was designed to convey fashion image experiences in a virtual environment, from which a haptic rendering model was suggested. The effectiveness of the haptic communication system was evaluated by verifying user experiences with questions developed through a user evaluation experiment. The validity of the evaluation questions pertaining to the tactile attributes and the effects of the haptic communication system were verified. Factor analysis was conducted to verify the evaluation of the tactile sense attributes of the fashion material, which identified density, thickness, and elasticity of the material as key factors. As a result of comparisons between the tactile sense through haptic characteristics and through touching, it was observed that regarding density and thickness, tactile sense experience led to greater perceived reality, while this was not the case for elasticity.
