Objective: The purpose of this study is to define the space type for the seat of autonomous vehicle and to find the type of space preferred by the driver. Background: The autonomous driving car is a secondary living space that is not simply a means of transportation because the driver and passengers are not responsible for driving because everyone can use the car, and as the spatial meaning extends to the working space, it is important for the driver and the passenger to be provided with the service at the time of making the request. Method: In order to carry out the research, a total of 10 spaces were derived from each company"s self - driving car case study, and it was defined as 5 steps according to autonomous driving stage 3 and 5 stages based on autonomous driving stage The survey results were classified according to gender, marriage, driver"s gender, age, marriage status, family members, and purpose of car use, and conducted a recursive 5-point scale (one point very dissatisfactory/two points dissatisfaction/3 points average/4 points satisfaction/5 points) In the final conclusion, based on the preference of each type of space derived from the questionnaire, the representative subjects of the questionnaire were selected and interviewed, and the research was completed with qualitative survey. Results: "Back seat (forward / backward)" was the most favorable choice for drivers. Conclusion: In the Level 3 of autonomous driving, we preferred the space configuration that is conveniently used in lines that do not deteriorate safety. In addition, users" expectations for autonomous vehicles have not been favored, and the composition of monotonous spaces such as internal combustion engine cars is not preferred. In the Level 5 of autonomous driving, it was free from the responsibility of driving, so it needed a space to meet various purposes. For various purposes, I preferred seat arrangements that can be used as a variable type, such as the separation and rotation of seats. Among them, the preference for seat design that can be used independently is higher than the non-independent form such as the front seat integral type. Application: This study can be most meaningful in analyzing the requirements for the direction of the space design of autonomous vehicles in the future.

환경오염 문제를 해결하기 위한 노력과 기술의 발전에 힘입어 전기 자동차의 보급이 확산되고 있다. 그 중, 운전자에게 자동차의 현재 상태를 전달하고, 주행과 차량 관리에 필요한 정보를 제공하는 대시보드의 역할은 가장 중요한 요소 중 하나라고 볼 수 있다. 전기자동차는 배터리 잔량에 대한 민감함 등으로 인해 기존의 내연기관 자동차와는 운전 방식이 크게 달라졌지만 대시보드는 유사한 방식으로 설계되었다. 현재까지의 자동차 대시보드는 주행의 편의를 목적으로 하여 정작 운전자에게 필요한 적정의 정보량과 전달되는 디스플레이 별 정보 배치 가이드라인은 명확하게 이루어지지 않고 있다. 특히 계기판은 자동차와 관련된 중요한 정보 및 안전관련 정보를 운전자에게 제공하는 부분이기 때문에 이를 중점으로 한 연구는 더욱 필요하다고 보여진다. 따라서 본 연구에서는 대시보드에 초점을 맞추어 전기자동차 운전자에 적합한 정보 제공을 위한 대시보드 디자인에 대해 제안하고자 한다. Increasing efforts to solve the problems of environmental pollution and technological advances, the propagation of electric cars is spreading through out the world. A dashboard being one of the most important factors of electric cars, it communicates the current state of the vehicle with the driver and provides necessary information for driving and managing the vehicle. Although the sensitivity of the remaining battery has significantly changed the way electric cars operate compared to conventional internal combustion vehicles, the dashboard is still designed in a similar way. Up to now, dashboard design is mainly focused on facilitating driving and has not been clearly provided with guidelines for display layout of each specific information that needs to be delivered to drivers with appropriate amount. Further studies on this are considered necessary since the dashboard delivers safety-related information to the driver. Therefore, this study focuses on dashboard and proposes design of the dashboard that is suitable for electric car drivers.

The arrival of COVID-19 has brought about a certain change in the lifestyles of the public and traditional consumer habits and behaviour. Due to the rapid development of the "Quarantine Economy" during the epidemic, takeaway orders have become a way of eating be closely linked to people's lives. At the same time, problems such as contamination of traditional takeaway food packaging have been accentuated by the arrival of the epidemic. As a result, takeaway food packaging needs to change quickly to adapt to market conditions and new consumer demands in the epidemic environment. This study analyzes the existing takeaway food packaging recycling from previous research. And then, it optimizes and integrates the forms of takeaway food packaging recycling. Thus, the process of takeaway food packaging recycling and its feasibility is investigated at various stages. Ultimately, this study compiles four critical factors that influence takeaway food packaging recycling, which are the cost factor, raw material factor, promotive factor, and social factor. This study uses orthogonal experiments to compare the extent to which these four factors lead to consumer influence on takeaway food packaging recycling. This study was carried out to analyze the importance of each factor through the De-duplication Optimization method and Orthogonal Experiments, using visual analysis and variance analysis for comparative observations. The influence on takeaway food packaging recycling is in descending order of cost factor, raw material factor, promotive factor and social factor. In particular, the cost factor has the most significant impact, while the social factor does not have a significant effect. The ranking of the four factors in terms of the degree of influence can improve the efficiency of existing takeaway food packaging recycling, increase resource utilization and protect the ecological environment. This study provides more optimized options for industries utilizing takeaway food packaging.

Interactive art is completed with the participation of the audience. Therefore, the artist should consider various design elements to induce audience participation, and these should be designed with an intuitive interface for easy use with simple manipulation. Soundscape is a combination of sound and scape, and it is one of the areas that has been continuously studied in the field of acoustic engineering. The soundscape, which utilizes white noise that can provide comfort, stability and immersion by generating alpha waves among human brain waves, has recently been used in the design of various products and services. This paper focuses on "Sound Cube," an interactive art work that allows customizing of soundscape, which has been actively researched recently in the field of auditory experience design. When planning and designing "Sound Cube," we would like to introduce the interface design to attract the participation of audience and present the knowledge of soundscape, features and affordance of the work. 인터랙티브 아트는 관람자의 참여를 통해 작품을 완성한다. 따라서 작가는 관람자의 참여를 유도하기 위해 다양한 디자인 요소들을 고려해야 하며, 이러한 디자인 요소들은 간단한 조작으로 쉽게 사용할 수 있도록 직관적인 인터페이스로 설계되어야 한다. 사운드스케이프는 사운드와 스케이프의 합성어로 음향 공학 분야에서 꾸준히 연구해오던 분야 중 하나이다. 인간의 뇌파 중 알파파를 발생시킴으로써 편안함, 안정감, 몰입감 등을 제공할 수 있는 백색 소음을 활용한 사운드스케이프는 최근 다양한 제품 및 서비스 디자인에 활용되고 있다. 본 논문은 관람자의 간단한 조작을 통해 최근 청각 경험 디자인 분야에서 활발하게 연구되고 있는 사운드스케이프를 직접 제작할 수 있는 인터렉티브 아트 작품인 “사운드 큐브”를 중심으로 연구되었다. “사운드 큐브”를 기획, 제작하면서 관람자의 참여를 유도하기 위한 인터페이스 디자인을 소개하고, 사운드스케이프에 대한 지식, 그리고 작품의 특징 및 어포던스 분석 등을 제시하고자 한다.

Among the phases of self-driving, the transition of control over driving from vehicles to drivers occurs in the conditional self-driving phase. Therefore, designing appropriate user interfaces to perform safe control transitions is crucial. However, most previous studies have focused on evaluating the performance and safety of self-driving systems. In the conditional self-driving phase, no regulations that can force drivers to control their eyes currently exist, meaning the control transition, which relies solely on the visual-centric user interfaces used in traditional driving environments, is not safe. Therefore, in this study, we developed guidelines for an auditory user interface design to ensure safe control transition. We derived these guidelines by applying a user experience design methodology and defining important principles in the appropriate combination of voice and sound feedback. 자율주행 자동차의 단계 중 제한적 자율주행 단계에서는 자동차와 운전자 사이의 운전에 대한 제어권 전환이 상호적으로 발생하게 되므로, 안전한 제어권 전환을 수행할 수 있는 사용자 인터페이스의 동작 시나리오 설계가 필요하다. 하지만 기존 연구의 대부분은 자율주행 시스템의 성능과 안전성을 평가하는 데 초점이 맞추어져 있다. 제한적 자율주행 단계에서는 운전자의 시선을 강제로 제어할 수 없으므로 기존의 주행 환경에서 사용되던 시각 중심의 사용자 인터페이스에만 의존한 제어권 전환 시나리오를 설계할 수 없다. 따라서 본 연구는 기존 연구와 달리 사용자 경험 디자인 방법론을 적용하여 제어권 전환 시에 운전자의 경험을 고려한 청각 사용자 인터페이스의 동작 시나리오를 제안하고자 한다. 음성 피드백과 사운드 피드백의 적절한 조합으로 구성된 청각 사용자 인터페이스는 안전한 제어권 전환을 도울 수 있다.

Objective: The purpose of this research is to investigate the space types and user needs in the co-living space, to find out the design direction of co-living in the postpandemic era. Background: As a kind of service-type residence, 'Co-living' housing has become a new living trend in recent years. In the post-pandemic era, user residential needs have changed, and it is necessary to rediscuss the design direction of co-living space. Method: Firstly, According to literature research, the space type of co-living is obtained, and based on it, user needs are investigated through focus group interviews. Then, according to the user's usefulness survey, SPSS is used to classify the user needs and find the design direction. Finally, according to the design direction, suggestions are put forward for the combination of co-living spaces in the post-pandemic era. Results: The research found that co-living user needs are mainly composed of three parts: 'service', 'facility' and 'construction', which have different directions according to the usefulness of the needs: In the service direction, focus on the use of services to maintain the healthy operation of the community; In the facility direction, the functionality of public space needs to meet the user's pursuit of health and the life pattern of integrating work and housing; In the construction direction, the reasonability of the structure and the safety of living are pursued. According to the obtained results, the combination of space types is discussed from vertical and horizontal. In terms of vertical space connection, co-living houses in the post-pandemic era are more suitable for single-family apartment buildings. In terms of horizontal space combination, it is necessary to select the complex space combination form according to the space type and analyze it separately. Conclusion: In the post-pandemic era, in order to cope with the new needs of coliving houses derived from users, choosing an appropriate spatial configuration form can guide users to use the space rationally and better improve user experience. At the same time, it is necessary to provide comprehensive services, facilities, and reliable construction. In the context of social development, we should actively pay attention to the changes in the residential environment, and conduct continuous research on the user needs in co-living space. Application: This study provides the design direction of co-living space residences in the post-epidemic era, which can be used for the future development and progress of co-living spaces.
