Robot control involves advance programming, scientific and high technology. The systematic and methodological aspects of robot controls often results in having superficial control design problems that can negatively affect the robot application, usability and appeal. User friendly interface of robot control is extremely advantageous and more attractive. To illustrate, the application of medical robot is usually handled by clients who have little background in advance programming language. Thus, it would be difficult if the client needs to use programming language to control the robot. It would justify better if the robot control is presented in a meaningful interface to the client. This way the robot application would be more natural and user friendly. This paper describes the method of developing the user interface for web based communication to control an internet robot named Tarou. The web based communication tasks involves three levels. The first one accommodates on the client sending commands to robot through the internet. The next communication level relates to the robot receiving the commands sent by the client. The final communication level generates on sending feedback on status of commands by the robot to the client. The methodology used here can be elaborated in four hierarchical steps; identify user needs and robot tasks, identify the enhancing tag reference used by the server, induce the tag into HTML, present the HTML in attractive user interface as the client control panel.

In recent times, Natural User Interface/Natural User Experience (NUI/NUX) technology has found widespread application across a diverse range of fields and is also utilized for controlling unmanned aerial vehicles (UAVs). Even if the user controls the UAV by utilizing the NUI/NUX technology, it is difficult for the user to easily control the UAV. The user needs an autopilot to easily control the UAV. The user needs a flight path to use the autopilot. The user sets the flight path based on the waypoints. UAVs normally fly straight from one waypoint to another. However, if flight between two waypoints is in a straight line, UAVs may collide with obstacles. In order to solve collision problems, flight records can be utilized to adjust the generated path taking the locations of the obstacles into consideration. This paper proposes a natural path generation method between waypoints based on flight records collected through UAVs flown by users. Bayesian probability is utilized to select paths most similar to the flight records to connect two waypoints. These paths are generated by selection of the center path corresponding to the highest Bayesian probability. While the K-means algorithm-based straight-line method generated paths that led to UAV collisions, the proposed method generates paths that allow UAVs to avoid obstacles.

This study proposes the method seeking out the user needs for the home automation systems which are one of the compositions of digital home. The findings are as follows. (1) The designing of digital home should be based on the residents' daily life and the their needs for the future house prior to the digital technology, (2) The IT Apartments recently developed in Busan set up the safety and security system and the automatic ventilation system mostly. (3) The residents are more concerned of the safety and security and the comfortable interior environment than convenience and entertainments. (4) The residents have diverse needs for the home automation systems according to their age, residential experience and occupation.

This paper tries to a n.0, pply the concept and process of marketing which have been developed in profit sector to library management. Since the end of 60's certain marketing researchers, among them Kotler, Levy, and Shapiro have advanced the theseses that marketing is not just a business organization as well. Recently libraries have been interested in markeing also. Marketing is a concept of sensitively serving and satisfying human needs through voluntary exchanges of value. Library is a value exchange system in which library service is exchanged with community's patronage. In order for library user to involve in the value exchange system voluntarily, library should analyze user's needs and offer products satisfying the needs. For doing this, library should understand marketing. In this paper, author introduces the marketing concepts and process, tries to show how to a n.0, pply the key concepts and process to public library management. The needs of marketing in library sector, the effectiveness and barriers in a n.0, pplying marketing to library also discussed.

This research was conducted to investigate the voice related needs of occupational voice users. The data collected from teachers(379), tele-marketers(156), therapists(50) was classified according to its content, by colaizzi's inductive categorical analysis. The voice related needs are classified into 3 big categories, 1) how to use, 2) how to care, 3) how to be healthy. Again the category 'how to use' my voice was into 6 sub-categories: (1) efficiently, (2) as I desired, (3) without pain(discomfort), (4) expressively, (5) phonation (methods) and (6) clear articulation. The result showed that the needs from 3 groups of occupational voice users reflect their own environment which they have to use their voice as well as the voice characteristics wanted from their specific listeners.

User-led IS development contributes to the response of actual user needs, the alternative solution for backlog, and including the enhanced communication and the reduced role conflict between users and DP department. However, there are too little research and practical concern about the user-led IS development. This case study on the Korea Real Estate Investment Trust addresses to the development background, IS development process, and the qualitative and quantitative benefit of user-led IS development. We believe that the case study contributes to the understanding for the benefit of user-led IS development approach.

In this study, user survey and some experiments were carried out to identify older adults' characteristics and needs for shower chair design. Firstly, the category and design components of shower chair were analyzed through product analysis. Secondly, older adults' needs for shower chair were identified through user interview and observation. Thirdly, experiment to measure older adults' motion, EMG, and body pressure while using shower chair was carried out and then older adults' characteristics for the use of shower chair were identified. Finally, the direction of design for shower chair was proposed to improve older adults' satisfaction.

As the interest and use of computer have been increased among elderly users according to the entry to the aging society, the issue of universal design for computer usability was brought forward. Especially, it is widely recognized that universal UI(User Interlace) design on MS windows is important. The objective of this study is to conceptualize Universal GUI design on MS windows which can be used more easily and intuitively by novice users such as elderly and housewives. Especially, the solution for Universal GUI design on MS windows was developed by reflecting elderly users' needs because elderly users is the group with more difficulties than other user groups in learning and using MS windows. First, elderly user's needs was collected by participant observation as a teaching assistant in computer dass for elderly people for 4 weeks. Secondly, the experimental test and in-depth interview was implemented to find difficulties factors and needs in addition to participant observation. Based on the findings, the new GUI design solution was suggested. The design solution consists of ideas in several categories such as setting default, simplification of function for easy conceptual model making, customization of function and working environment, and intuitive GUI in interaction process. The new MS windows GUI design can be accessed by novice mode when user login in window XP. This study has the significance in finding elderly users detailed needs through in-depth and long term participant observation. However, the usability of the suggested prototype needs to be verified to various user groups besides elderly users in the future.
