Since the two-way interactive broadcasting service began, remote controllers have been fitted with 4 color buttons, which enable interaction and convenience to grow between users and content. With Currently, diverse studies on IPTV are in progress. Particularly, as the mobile market rapidly grows, studies on mobile IPTV and on linkage with other media are constantly increasing. Yet, mobile IPTV has never been studied as of now. In that sense, the present study attempted to design a mobile-based IPTV UI that is fitted with more usability and functionality of 4 color buttons and multi-dimensional search based on consistent criteria for content search. The UI designed in this study was estimated using user interface design guideline. The guideline is comprised of consistency, user centered, ease of use, forgiveness, feedback, functionality, aesthetic integrity.

In this paper, we present a overview of content-based image retrieval (CBIR) systems: its results and its problems. We propose our CBIR system currently based on color and texture. From the CBIR systems. we discuss the way to add semantic values in image retrieval systems. There are 3 ways for adding them: concept definition, machine learning and man-machine interaction. Along with this we introduce our preliminary results and discuss them in the goal of reaching semantic retrieval. Different result representation schemes are presented. At last, we present our work to build a complete annotated image database and our image annotaion program.

Activity structures are a set of functional structures which may be used to provide a uniform framework for the description of information processing systems. The interaction of some aspects of activity structures is discussed. Intelligent systems, a subset of information handling systems, are the primary emphasis of this work. An extension to the functional structures of the activity structures is proposed. The proposed structure is a met a-structure which affects most elements of an intelligent system. The structure is concerned with describing the way uncertainty in an environment is handled by a system. An example is given which shows the importance of describing the uncertainty handling method(s) of an intelligent system.

The purpose of this study was to probe into the recognitions of mother's role and children behaviors to learn the relationships between mother and child with externalizing behaviors. The subjects were 4 mothers of 4- to 5-year-old externaling children on Korean edition of CBCL. As a way of obtaining more information of mother-child interaction, in-depth interviews were used. The data from interviews were presented in an edited descriptive form. The major findings of this study were as follows : 1) Mothers treated children's wrong behaviors in a coercive manner. 2) It seems that a mother's expectations to be a good mother result in coercive or poor behaviors on externalizing children. 3) Mother had difficulties in handling the children's behaviors and she attributed the reason of wrong behavior to the personality or intention. 4) Mothers seemed to have close relationships with the other than one with externalizing children.

In this paper show how to design a redundant robot which is suitable for the multiple task without any constraints on the workspace. The implementation is possible by the rigid connection of a mobile robot and a task robot. Use a five joint articulated robot as the task robot; designed the 3 joint mobile robot for this usage. For a task execution assigned to the redundant robot, not only the task robot but the mobile robot should work in the coordinated way. therefore, a kinematic connection of the two robots should be cleary represented in a frame. And, also the dynamic interaction between the two robots needs to be analyzed. Clarified these issues considering the control of the redundant robot. Finally, demonstrate away of utilization of the redundancy as the cooperation between the mobile robot and the task robot to execute a common task.

Understanding of human emotion has a high importance in interaction between human and machine communications systems. The most expressive and valuable way to extract and recognize the human's emotion is by facial expression analysis. This paper presents and implements an automatic extraction and recognition scheme of facial expression and emotion through still image. This method has three main steps to recognize the facial emotion: (1) Detection of facial areas with skin-color method and feature maps, (2) Creation of the Bezier curve on eyemap and mouthmap, and (3) Classification and distinguish the emotion of characteristic with Hausdorff distance. To estimate the performance of the implemented system, we evaluate a success-ratio with emotional face image database, which is commonly used in the field of facial analysis. The experimental result shows average 76.1% of success to classify and distinguish the facial expression and emotion.

The current research brings the spotlight onto customer Gapjil toward service employees. In an attempt to understand what brings Gapjil, the present article investigates the intertwined effects of perceived economic mobility (PEM), self-other referent priming (SORP), and temporal focus on Gapjil. Study 1 shows that PEM increases Gapjil among self-referent primed people, but not among other-referent primed people. Study 2 examining the role of temporal focus (present vs. future) reveals that the effect found in study 1 is replicated in the present focus, but the effect is reversed in the future focus. We explain this dynamic pattern of the 3-way interaction effect with a relative gratification and a motivation to attune the self to the perceived norm of the high class. We also discuss how to create a social atmosphere to lessen Gapjil in public and corporate communication strategies.

Tele-Gesture is a tangible user interface(TUI) device that allows a user to physically point to a 3D object in real life and have their gestures play back by a robotic finger that can point to the same object, either at the same time, or at another point in time. To understand the extent of the gestures as new way of digital collaborative communication, collaboration situation and types were experimented as TUI implementations. The design prototype reveals that there is a rich non-verbal component of communication in the form of gesture-clusters and body movements that happen in an digital communication. This result of analysis can contribute to compile relevant contributions to the fields of communication, human behavior, and interaction with high technology through an interpretive social experience.

The purpose of this study is to derive the characteristics of interaction design for each stage of content composition so that it can be referred to in the planning and production of virtual reality safety education contents. It was confirmed that each of the following interaction design features was found in the three configuration steps: acquisition of situation response procedure knowledge, accident situation experiential learning, and content confirmation and evaluation. First, it was revealed that the quality of experience was controlled by increasing the fidelity of behaviors and reducing general and repetitive behaviors in order to emphasize the educational content-related experiences in the learner experience stage. Second, in order for learners to easily recognize main interaction objects in order to acquire information on safe behavior procedures in unfamiliar environments, use of spatial UI or signifiers using arrows or symbols, posts that specifically instruct actions, and multisensory signals Therefore, it was found to be important to emphasize essential actions in a way that lowers the degree of freedom of user experience, and the proportion of non-realistic interactions for cognitive interactions was found to increase. Lastly, in the confirmation and evaluation stage of the experience, it is important to use the meta UI to alleviate negative experiences such as physical damage after experiencing a safety accident situation,

Objective : This study was designed to determine the effects of sensory integration group therapy with regard to the sensory processing, peer interactions, and task performance, and whether they continue. Methods : Twelve children aged 7 to 13 years enrolled in this study for 60 minutes per session, three times a week for 8 weeks. Sensory integration group therapy consisted of a total of 24 activities that included sensory processing, play skills, and interaction with peers. Short Sensory Profile was used to select subjects. In order to measure the outcome, we used the Short Sensory Profile, Penn Interactive Peer Play Scale and Canadian Occupational Performance Measure at pre, post, and follow-up evaluations. The results were analyzed by means of repeated measures analysis, and the pre-test, post-test, and follow-up tests were compared using the Wilcoxon matched-pair signed rank test. Results : After sensory integration group therapy, sensory processing, peer interaction, and task performance significantly improved(p<.05). In addition, we confirmed that the effects of treatment were maintained in the 4 weeks follow-up test. Conclusion : Sensory integration group therapy is an effective way of mediating effects not only by improving sensory processing skills, but also by providing imitation and training in groups for children in need of peer interaction and linking them to daily life.
