Recently emotional relationships between industrial products and user experience are getting more attention than ever. However, current user interface design has focused just on the mechanical and logical aspects. This research proposed a new approach to improve user's emotional experience to interface design and introduced storytelling as a new possibility. Four types of user interface - logical interface, picture added interface, storytelling-applied interface, and storytelling-applied interface with a story script - were used for this research. Eighty college students participated in this research. Each participant was randomly assigned to one of four types of user interfaces. Additionally, their individual differences in affect intensity were measured. he results show that users reported more emotional experience in the storytelling-applied interface and storytelling-applied interface with a story script than the logical interface and just picture added interface. The results also suggest that the higher satisfaction was experienced for the storytelling-applied interface. And all those results are differentiated by the users' affect intensity. The users who have higher affect intensity expressed heavier emotional experience and deeper satisfaction for the storytelling-applied interface.

This study proposes a text interface for support of language-based educational contents in a mobile platform environment. The proposed interface utilizes deep learning as an input structure to write words through handwriting. Based on GUI (Graphical User Interface) using buttons and menus of mobile platform contents and input methods such as screen touch, click, and drag, we design a text interface that can directly input and process handwriting from the user. It uses the EMNIST (Extended Modified National Institute of Standards and Technology database) dataset and a trained CNN (Convolutional Neural Network) to classify and combine alphabetic texts to complete words. Finally, we conduct experiments to analyze the learning support effect of the interface proposed by directly producing English word education contents and to compare satisfaction. We compared the ability to learn English words presented by users who have experienced the existing keypad-type interface and the proposed handwriting-based text interface in the same educational environment, and we analyzed the overall satisfaction in the process of writing words by manipulating the interface.

Efficient representation is crucial in the analysis of complex geospatial information. In case of aerial triangulation, most of currently available software are designed as black boxes where only an experienced user would be able to prepares the preformatted input file and interprete the result of the adjustment. This paper introduces a solution to this problem through the UML design of a Graphical User Interface (GUI) for the aerial triangulation task. The design was then implemented with ArcGIS. The error of the exterior orientation of each aerial Imagery was represented with a 3-D error ellipse, enabling the visualization of the adjustment result. The attributes of images and points (control points, tie points and image points) were maintained as a database which enables the searching and querying of adjustment information.

A virtual reality is a virtual space constructed by a computer that provides users the opportunity to indirectly experience a situation they have not experienced in real life through the realization of information for virtual environments. Various studies have been conducted to realize virtual reality, in which the user interface is a major factor in maximizing the sense of immersion and usability. However, most existing methods have disadvantages, such as costliness or being limited to the physical activity of the user due to the use of special devices attached to the user's body. This paper proposes a new type of interface that enables the user to apply their intentions and actions to the virtual space directly without special devices, and test content is introduced using the new system. Users can interact with the virtual space by throwing an object in the space; to do this, moving object detectors are produced using infrared sensors. In addition, the users can control the virtual space with their own postures. The method can heighten interest and concentration, increasing the sense of reality and immersion and maximizing user's physical experiences.

Network convergence is considered as one of the key solutions to the problem of achieving future high-capacity and reliable communications. This approach overcomes the limitations of separate wireless technologies. Efficient interface selection is one of the most important issues in convergence networks. This paper solves the problem faced by users of selecting the most appropriate interface in the heterogeneous radio-access network (RAN) environment. Our proposed scheme combines a hierarchical evaluation of networks and game theory to solve the network-selection problem. Instead, of considering a fixed weight system while ranking the networks, the proposed scheme considers the service requirements, as well as static and dynamic network attributes. The best network is selected for a particular service request. To establish a hierarchy among the network-evaluation criteria for service requests, an analytical hierarchy process (AHP) is used. To determine the optimum network selection, the network hierarchy is combined with game theory. AHP attains the network hierarchy. The weights of different access networks for a service are calculated. It is performed by combining AHP scores considering user's experienced static network attributes and dynamic radio parameters. This paper provides a strategic game. In this game, the network scores of service requests for various RANs and the user's willingness to pay for these services are used to model a network-versus-user game. The Nash equilibria signify those access networks that are chosen by individual user and result maximum payoff. The examples for the interface selection illustrate the effectiveness of the proposed scheme.

Kiosk is an unmanned information system arranged in public places or commercial spaces so that a user may utilize information conveniently. Unlike a personal computer, it targets varied users' brackets, so we have to consider a user's characteristic in designing Kiosk Interface. However, in reality, the Kiosks of public places like subway stations are of Interface Design without considering users and become almost useless with serviceability falling. In this study, we attempt to point out such problems and suggest the concept as to the Interface Design in the public places for a more positive promotion method. For this purpose, we are about to look into the concept of Tangible Interaction and Interspace and the recreation experienced in the process of interaction between a human and a computer and study the sportive Kiosk Interface Design in the Interspace using the principle of the Tangible Interaction. For the conceptual Model in this study, we referred to ARTCOM(ART+COM) Project.

In this study, the hardcore game user verified the manipulation delay that occurred during VR game play because of the experienced game. Based on the HCI - based research approach, we created a 2D, 3D, and VR prototype game with user manipulation cycle hypothesis. Based on this, 121 users were experimented with 2D, 3D, VR format user interface. The average user manipulation period extracted by the experiment was compared with the independent sample T test. Based on the test results give the average time difference between the user's operation of the 2D VR format has been verified. User operation period of the average time difference in 3D VR format proved the null hypothesis of no significant difference has been adopted.

Screen Golf provides a more realistic interface to users by implementing sophisticated sensors and 3D graphics so that they can play golf in an environment almost identical to the actual golf course, to provide a sense of reality that goes beyond simply enjoying golf indoors. In addition, users who experienced this interface environment showed a tendency to feel the fun of golf more and become more immersed in golf. Therefore, it is most important to provide an effective realistic interface in screen golf. In this study, the meaning of screen golf as a tangible sport and various interface elements embodied in screen golf were summarized. Also the factors that enable users to feel reality and fun of actual golf to make users more immersed in screen golf were identified. For this, interface elements based on sensory elements were arranged in terms of visual, auditory, and tactile sense, and improvement plans and directions for providing effective sensory interfaces for screen golf were suggested through user FGI, targeting regular customers of Golfzone and KakaoVX screen golf, and in-depth interviews with experts. As a result of the analysis, it was confirmed that the course information including the yardage and the play situation-directed graphic are elements that make immersion in the visual aspect. In terms of tactile aspect, the fact that users actually use golf equipment, as well as the sense of existence of a physical interface that embodies various course environments and course setting appeared to be an important factor. In particular, in the auditory aspect, it was confirmed that providing customized services for each user through AI caddy implemented to resemble a actual caddy is the most effective way to immerse users in screen golf with greater fun and realism.
