In this paper, we propose a digital human content creation system. The digital human content creation system works with 3D AI modeling through whole-body scanning, and is produced with 3D modeling post-processing, texturing, rigging. By combining this with virtual reality(VR) content information, natural motion of the virtual model can be achieved in virtual reality, and digital human content can be efficiently created in one system. Therefore, there is an effect of enabling the creation of virtual reality-based digital human content that minimizes resources. In addition, it is intended to provide an automated pre-processing process that does not require a pre-processing process for 3D modeling and texturing by humans, and to provide a technology for efficiently managing various digital human contents. In particular, since the pre-processing process such as 3D modeling and texturing to construct a virtual model are automatically performed by artificial intelligence, so it has the advantage that rapid and efficient virtual model configuration can be achieved. In addition, it has the advantage of being able to easily organize and manage digital human contents through signature motion.

Video digital door lock(VDDL) system detects people who access to the door and acquires the human image. Design considerations is that current consumption must be minimized by applying fast human detection algorithm because of battery-based operation. Since the digital door lock takes an image through a fixed camera, detection of a person based on background image leads to high degree of reliability. This paper deals with a single human detection algorithm suitable for VDDL with fulfilling these requirements such that it detects a moving object in an image, then identifies whether the object is a person or not using image processing. The proposed image processing algorithm consists of two steps: Firstly, it detects the human image region using both background image and skin color information. Secondly, it identifies the person using polar histogram based on proportional information of human body. Proposed algorithm is implemented in VDDL and is verified the performance through experiments.

Advancements in technology and the proliferation of digital services have highlighted the importance of luxury brands in service environments. Based on the social exchange theory, this study investigated the interaction between customers and luxury brands in a traditional offline service encounter and a digital online service encounter. The interaction area was classified into three parts: human-human, human-digital, and human-physical environments. We qualitatively investigated the practitioners' working experiences with luxury brands. The study determined that both online and offline service encounter interactions between luxury brands and customers have become diverse. First, forming a special relationship with customers and frontline employees in traditional service encounters is important. Second, luxury brands should focus on the interaction among customers. Third, various digital tools should be considered to provide information about the brand to customers. Fourth, the exclusive benefits of offline service encounters should be maximized to stimulate positive experiences. The findings provide valuable insight to scholars and marketers on the new interaction phase between customers and luxury brands in the digital age.

Ubiquitous space can be described as a combined space of physical space and digital space. Ubiquitous space possesses new possibilities by combining the two. The concept of ubiquitous home will bring new changes in residential space design. First of all, it makes possible for more convenient and secure home. It has to be developed along with city and town level changes as ubiquitous environment. Secondly, concept of extended space as an extension of living space becomes possible by linking with outside spaces. Thirdly, as consumer requirements for residential spaces will become more versatile by social changes, ubiquitous home can be a good means to meet these versatile consumer requirements by accommodating concept of multi-functional space and flexible space. It is quite important to predict user requirements in rapidly changing social environment and versatile personal inclinations. Instead of POE methodology which can analyze and evaluate in exiting types of designs, storytelling methodology can be used to predict and direct for future requirements of living. The methodology makes scenarios of space usage for future living and extracts design requirements for the living. The concept of intelligent space has to be introduced. It is different from digital home that only accomodate digital devices in space. In intelligent space, space itself has to be recognized as an identity that interacts human directly. Intelligent space recognize human requirements and control digital devices as a response. Multi-functional space is closely related with intelligent space that can changes for business, entertainments as well as for rests by user requirements instantly. Flexible space that also intends to meet requirements of mobility and versatility can be attained through the integration of digital technology into current physical mobile systems. Interaction design becomes integral part for ubiquitous space design along with physical design. For the residential space design, digital illiteracy has to be considered for interaction design. Instead of the concept of passive existence, space itself has to be recognized as active subsistence that reacts with human. Intuitive and natural interaction for human will be a key design element for space-human interface design.

Surface has been an important issue in contemporary architecture. That originates in structural freedom of surface since the end of modern architecture and the current stream of surface becoming an identity of building. Development of digital-media has brought a great change to our society in general. Digital-media is characterized by use of digital-information and interactive communication. Digital-media has been applied on surface in contemporary architecture lately. It is a purpose of the study to analyze the characteristics of digital-media application on surface based on the related characteristics of installation art. The categories and the contents for the frame of case analysis were arranged through document research. The foreign and domestic cases of digital-media application were analyzed based on the frame of analysis. Digital-media, which is installed on surface, is interacted with human and surroundings. It enhances emotional communication between human and architecture. Surface is not any more a simple fixture but an interactive creature. It makes surface more dynamically and fluidly that the course of light and human movement affect on digital-media. Surface itself is also turned into an object of art. It reflects the interweaving characteristics between contemporary architecture and installation art. It was analyzed through the study that emotional level of people is the important issue shared in digital-media application on surface and installation art. The complementary relationship between surface of contemporary architecture and installation art can be manipulated by the application of digital-media on surface.

CNS (Car Navigation System) is the most compatible candidate among various in-vehicle information systems as a provider of ITS (Intelligence Transport Systems) information. It generally consists of remote controller, display, CD-changer, GPS receiver and so on. Among them, display is the most important and critical element of the HMI (Human-Machine Interface) suggesting the digital map to the driver. Therefore, it is certain that the display gives cognitive, physical, mental and visual workloads to the driver which are directly related with the driver's and road safety with the success of ITS. Until now, various human factors techniques have been developed and applied to estimate the driver's workload and to collect the driver's requirements of the CNS digital map, for example, mental workload assessment, visual activity analysis, cognitive analysis and so on. In addition to these kinds of techniques, this research performed the human sensibility ergonomics approach to directly investigate and evaluate the driver's requirements and sensibilities of the real products.

This study explores the potential of automated speech recognition (ASR) in assessing English learners' pronunciation. We employed ASR technology, acknowledged for its impartiality and consistent results, to analyze speech audio files, including synthesized speech, both native-like English and Korean-accented English, and speech recordings from a native English speaker. Through this analysis, we establish baseline values for the word error rate (WER). These were then compared with those obtained for human raters in perception experiments that assessed the speech productions of 30 first-year college students before and after taking a pronunciation course. Our sub-group analyses revealed positive training effects for Whisper, an ASR tool, and human raters, and identified distinct human rater strategies in different assessment aspects, such as proficiency, intelligibility, accuracy, and comprehensibility, that were not observed in ASR. Despite such challenges as recognizing accented speech traits, our findings suggest that digital tools such as ASR can streamline the pronunciation assessment process. With ongoing advancements in ASR technology, its potential as not only an assessment aid but also a self-directed learning tool for pronunciation feedback merits further exploration.

The evolutions of human mental capability and technology opened a new era called "Digital Space." Moreover, Digital Space as technology is already accelerating the process of "self-expansion." The expansion, on the foundation of its conceptual and morphological variety, acquired the potential to furnish various types of spatiotemporal experience. This phenomenon, as a necessary consequence of focusing on the resulting value of the human-space relation which came next to its ontological value, requests the value of the space design as an attempt of various phenomenal experience in the relation of technology, human, and space to be educationally established. From a typological point of view, no true creation exists in any form of design. It is practically impossible to design in the void without any restrictions, and all design is based on preceding examples. This is because production of artificial is based on the universal principles or structure residing in history, namely, typology. Considering Digital Space from technological and cultural standpoints, it can obviously be called a new type of space, and beyond that, it becomes a new type of a methodological tool of design. Thus, the purpose of this study is to systematize the paradigm of the space design in the digital era by studying the concept of space in Digital Space from the standpoints of history and context, that is typology, and in accordance with it, classify the phases of the space design that is led digitally.at is led digitally.
