This paper proposes a middleware structure for the module-based personal robot, which can run on heterogeneous network interfaces and provides users easy interface-method regardless of underlying heterogeneous interfaces and convenient exchange of modules. The proposed middleware is divided into three layers of a streaming layer (SL), a network adaptation layer (NAL) and a network interface layer (NIL). The streaming layer manages application transactions using middleware services and provides user a uniform interfaces to the proposed middleware. The network adaptation layer manages a message-routing and provides naming service and it is a core of the proposed middleware. And the network interfaces layer manages dependent parts of heterogeneous network interfaces such as IEEE1394, USB, Ethernet, and CAN (Control Area Network). This paper implements the proposed middleware structure, where 3 types of interfaces of IEEE 1394, USB and Ethernet are used, and measures response times among those interfaces.

본 연구는 현대인의 필수품이라고 할 수 있는 스마트 폰 사용 환경 속에서, 카메라 애플리케이션과 촬영한 사진을 SNS에 공유하는 조작 환경에 대해 사용자 경험을 연구하였다. 이를 위하여, 조작, 편집, 공유 등 3가지 측면을 중심으로 총 10가지의 태스크를 선정하여 20대 남녀 각각 4명, 총 8명을 대상으로 태스크 수행을 한 후 수행시간을 측정하였다. 안드로이드 모바일 운영체제의 대표적인 사용자 인터페이스인 Samsung Experience 8과 LG UX 6.0을 중심으로 진행된 실험 결과, 3가지 측면에 대해서 인터페이스별로 사용성의 차이가 있다는 것을 확인할 수 있었다. 실험 과정에서 피실험자 모두 조작의 편이성과 다양한 기능을 장점으로 꼽았다. 하지만 다양한 기능을 설정할 수 있는 만큼, 텍스트 기반의 복잡한 인터페이스는 사용하는 데 어려움이 있었다. 향후, 사용자 인터페이스별로 카메라 애플리케이션의 사용성 향상을 위하여 지속적인 연구가 필요할 것이다.

Evaluation of user interfaces has to be performed in an intuitive and subjective manner by experts especially when the problem comes to the complexity and consistency of sophisticated interface procedures. The manual analysis and evaluation of logical interfaces also tends to be slow and laborious. To make the evaluation more formal and objective, the criteria and the procedure with which the evaluation can proceed must be explicitly prescribed. Furthermore, to make the formal procedure as practical as subjective expert evaluation, the criteria must reflect the user knowledge of the target tasks since the task knowledge plays the role of a basis for users to understand the interface organizations and procedures. This paper describes ESTIM, a support system for task-based evaluation of user interface, that includes the interface evaluation criteria and implies an evaluation procedure. The support system can be used either in an interactive manner by the analyst during the evaluation or in an automatic evaluation mode. It was verified that the result of automatic evaluation by ESTIM matched the results of expert evaluation fairly well.

컴퓨터 사용의 역사를 보면 인터페이스 메타포는 사람들이 컴퓨터를 더 사용하기 쉽게 만드는데 쓰여왔다. 심지어 초기의 command line 인터페이스에서도 메타포를 사용해 왔었다. 사용자 인터페이스에 있어서 메타포는 사용자들을 시스템에 접근하기 쉽게 만드는 것을 도울 뿐 아니라 사용자들과 시스템과의 연결 통로라고 할 수 있다. 따라서 본 논문은 사용자 인터페이스에 있어서 성공적인 메타포 구축을 위해 conceptual model을 고려하여 Gestalt 원리를 활용한 지침을 제시함으로써 도움을 주고자 한다.

Menu-driven interfaces are frequently employed for user -system interfaces on many electronic products. Due to the space and budget constraint, a single or multi-line display is used to show menu items. Single or Multi-line display present 8 .approx. 21 characters on an LCD screen and users select items using a series of button pushes. Multi-line displays are different from the single-line ones in the following aspects. First, they can present multiple menu items at the same time. Second, they can present menu items in a various way, for example, same-depth presentation, sub-depth presentation, previous selection, etc. In this study, a human factors experiment is being conducted to examine the effects of three independent variables on the design of a multi-line display. Factors investigated include menu structure, number of lines on the display, item presentation methodl. Usability of the multi-line display is being measured quantitatively in terms of four different aspects: task completion time, accuracy, inefficiency, user preference. A set of design guidelines will be drawn from this study which can be applied to usef-system interfaces of a various types of consumer products.

In this paper, we introduce the multimodal user interface technology, especially based on speech. We classify multimodal interface technologies into four classes: sequential, alternate, supplementary, and semantic multimodal interfaces. After introducing four types of multimodal interfaces, we explain standard activities currently being activated.

Purpose: This study aimed to design user interfaces of a mobile application for managing pressure injury patients in a long-term care hospital based on the user's needs. Methods: To reflect users' needs in the mobile application, the user interfaces in this study were designed in five steps: brainstorming and mind mapping, persona and scenario, needs list and priority, a draft version of flow chart and user interfaces and expert review. These steps were conducted with a step nurse at a long-term care hospital, a professor who majored in nursing informatics, a professor who had lots of research experiences about pressure injury and a wound ostomy continence nurse. Results: Two personas, scenarios and needs' lists were derived. Listed Needs included the followings; Accurate staging of pressure injury; Appropriate management by staging; Acquisition of professional knowledge about pressure injury; Acquisition of easy pressure injury information through text, picture and video; and Sharing pressure injury information in unit. The structure, menus and features of the pressure injury mobile application were visualized with user flow based on two personas' scenarios and needs' lists. Conclusion: Our study suggests and visualizes the key features of the 'Pressure Injury Guide', a pressure injury management mobile application for nurses in a long-term care hospital, which can be utilized by nurses, application developers, and related researchers.

Visual occlusion method is a visual demand measuring technique which uses periodic vision/occlusion cycle to simulate driving environment. It became one of the most popular techniques for the evaluation of in-vehicle interfaces due to its robustness and cost-effectiveness. However, it has a limitation in that the vision/occlusion cycle forces the user to use the IVIS at a predetermined pace, while a driver decides when to use the device on his/her own in actual driving. This paper proposes a user-driven visual occlusion method for measuring the visual demand of in-vehicle interfaces. An experiment was conducted to examine the visual demand of an in-vehicle interface prototype using both the existing (system-driven) occlusion method and the proposed (user-driven) one. Two in-vehicle tasks were evaluated: address input and radio tuning. The results showed that, for the radio tuning task, there were significant differences in total shutter open time and resumability ratio between the methods. The user-driven visual occlusion method not only allows a better representation of drivers' behavior, but it also seems to provide more information on the chunkability of a task.
