The user interface (UI) is the part of the systems that users can see, hear and feel. That means, a user can interact with the systems through the user interface. Effective user interfaces create positive feelings of success and competence. In addition, they enable users to concentrate on their work, exploration, or pleasure. The German word "Gestalt" means "whole" as well as a figure or a shape. A comprehensive information systems (IS) literature review found that there has been little empirical evidence on the Gestalt principles in UIs that affect online users' perceived usability in a Web context. Therefore, the goals of this study are to 1) examine the relationships between Gestalt principles in UIs and online users' perceived usability in a Web context and 2) come up with design guidelines to enhance user success. Using a survey, this study explored the relationships between Gestalt principles used in six Web sites and 17 aspects of usability. The results showed that in terms of 16 aspects of usability, there are significant differences among the UIs that have different levels of Gestalt principles. In practice, online stores may use these findings to improve their Web pages. Specifically, the sixteen usability attributes can be used to check whether online stores' Web pages meet customers' user interface quality expectations.

Multimedia systems present information by various media, for example, video, sound, music, animation, movie, etc., in addition to the text which has long been used for conveying the information. Among many multimedia applications, the multimedia information retrieval systems commercialized in the forms of multimedia encyclopedia CD-ROMs, benefited from various media for their ability to present information in an efficient and complete way. But using several media, on the other hand, may cause end users' confusion and furthermore, poorly designed user interface often exacerbates the situation. In this study, the multimedia systems were studied from the standpoint of usability. The conceptual framework of the user interface of the multimedia system was newly defined. And 100 initial variables for user interface design of general multimedia systems were suggested through literature survey and expert opinions based upon the framework developed. Among various application areas, the multimedia information retrieval systems were chosen for investigation, and 36 variables particularly relevant to user interface of the multimedia information retrieval systems were selected. According to the sequential research strategy, the variables that were considered to be most important were finally selected through a screening stage. A part of selected variables were verified through a human factors experiment as the first step of sequential research. Based upon the result of the experiment, guidelines for user interface design were provided. For future study, the variables remained will be Investigated and the study will expand to another application areas.

This paper describes a design of graphical user interface for a simulated breeding tool with multifield. The term field is used here as a population of visualized individuals that are candidates of selection. Multi-field interface enables the user to breed his/her favorite phenotypes by selection independently in each field, and he/she can copy arbitrary individual into another field. As known on genetic algorithms, a small population likely leads to premature convergence trapped by a local optimum, and migration among plural populations is useful to escape from local optimum. The multi-field user interface provides easy implementation of migration and wider diversity. We show the usefulness of multi-field user interface through an example of a breeding system of 2D CG images.

Diverse operating systems and developed platforms of mobile devices are implemented by vendors exist. The software has to be developed by respective environment in designing the user interface of software. For the solution of the inconvenience, this paper proposes an integrated platform 4A DUOS for developing user interface independently. The proposed platform can use web language not dependent on various operating systems, and offer online access to API and component templates to provide the convenience of the user interface design. Also, the server with on board designed user interface implements the service to the user. Therefore, the users can design the independent user interface on various mobile devices by using only one source.

This paper presents a user interface for vision based indirect teaching of a robotic manipulator with Kinect and IMU (Inertial Measurement Unit) sensors. The user interface system is designed to control the manipulator more easily in joint space, Cartesian space and tool frame. We use the skeleton data of the user from Kinect and Wrist-mounted IMU sensors to calculate the user's joint angles and wrist movement for robot control. The interface system proposed in this paper allows the user to teach the manipulator without a pre-programming process. This will improve the teaching time of the robot and eventually enable increased productivity. Simulation and experimental results are presented to verify the performance of the robot control and interface system.

The User Interface (UI) in the company is more important than ever. But the application of UI for the industry use is restricted by various constraints such as delivery, technical limitation, etc. User Interface designers in the company have thought how to set up the UI organization, how to define identity and goal, how to communicate with other teams, what is the best UI process, and many other issues. In this paper, the author discuss the practical issues arisen when User Interface organization is formed and managed based on the mobile phone manufacture's perspective. The pros and cons of location of UI organization, advanced UI organization, UI member formation, UI role, UI output, UI evaluation, and understanding of UI in the society and company are discussed. This discussion will help UI designers in industry to set up and manage UI organization.

This paper deals with the design and the development of user interface for a high speed linear programming solving system. The general users' educational and practical requirements are analyzed and the functionalities that should be implemented for the requirements are designed. The user interface of the system consists of various carefully designed built-in commands that perform the functionalities. The names of the build-in commands are chosen to enhance the users' convenience. We also address the various factors that should be considered in the design of the linear programming solvers when integrated with the user interface. As one of user-friendly environments, data input system that can understand user-written arithmetic form is added to our user interface system. Finally, we compare our system with other user interface systems.

Designing a user interface is important because the user interface determines the level of physical and mental engagement of the user resulting in their level of learning. This paper investigated how physical engagement through a different user interfaces is associated with fun and learning and presented a theoretical physical engagement model called, PEM, developed based on an empirical user study. The PEM model describes how a game user interface is associated with the level of fun and learning, particularly in playing a full body engaged game. There are many different types of games but the Wii Tennis, an embodied interactive game, was chosen as an instance of full body engaged game. A user study with 32 participant's age ranged from 21 to 40 years old revealed that there is a positive correlation between both fun and learning and the level of physical engagement through two different user interfaces. The results of the study showed that the extent of fun and learning are associated with the physical engagement of the player through an interface. As an implication from the study, the result recommend that the level of user engagement is realized by an effective user interface, and the level of physical engagement is determined by the level of authenticity bridged by the user interface.
