Head-Up Display, an information-providing display, is a device that provides necessary information through a vehicle window for a driver when driving, with which the driver secures the visibility and acquires information necessary for driving. Head-up displays in early days were mostly installed in imported vehicles but increasingly, being installed in medium and large-sized domestic vehicles, they secures convenience of driving and information acquirement. The information display element of each of currently released brand cars not only has limits in consistency and in displaying interface but also reveals the limitation of a way to apply GUI, being applied to dot reflective form in terms of the technology type. Accordingly, this study draws real time information element described as necessary during driving through case survey and analysis, and aims to provide a user with new GUI guideline through transparent display technology recently developed based on results analyzed with priority of POI(Point of Interest) information.

This paper proposes a unified multi-modal input framework to interface the recognition engines such as IBM ViaVoice and Microsoft handwriting-recognition system with general window applications, particularly, for pen-input displays. As soon as user pushes a hardware button attached to the pin-input display with one hand, the current window of focus such as a internet search window and a word processor is overlaid with a transparent window covering the whole desktop; upon which user inputs handwriting with the other hand, without losing the focus of attention on working context. As well as freeform handwriting on this transparent input overlay as a sketch pad, the user can dictate some words and draw diagrams to communicate with the system.

Projection-based stereolithography is divided into constrained-surface and free-surface type according to controlling liquid layer. The constrained-surface type has a uniform layer thickness due to the use of a projection window, which covers the pattern generator such as liquid crystal display. However, the adhered resin on the projection window causes trouble and requires great separation force when the cured layer is separated from the window. To minimize the separation force, we developed a system to measure the separation force. The influence of material covering the pattern generator and the resin temperature is investigated in the system. Several structures according to the resin temperature and the velocity of z-axis elevation are compared. As a result, the fabrication condition to minimize the separation force reduces the process time.

This paper suggests a navigation information display system that is based on augmented reality technology. A navigator always has to confirm the information from marine electronic navigation devices and then compare it with the view of targets outside the windows. This "head down" posture causes discomfort and sometimes near accidents such as collisions or missing objects, because he or she cannot keep an eye on the front view of the windows. Augmented reality can display both virtual and real information in a single display. Therefore, we attempted to adapt AR technology to assist navigators. To analyze the outside view of the bridge window, various computer image processing techniques are required because the sea surface has many noises that disturb computer image processing for object detection, such as waves, wakes, light reflection, and so on. In this study, we investigated an analysis module to extract navigational information from images that are captured by a CCTV camera, and we validated our prototype.

Beam projector is popularly used for presentation. In order to pay attention to local area of the beam projector display, a laser pointer is used together with a pointing device(Mouse). Simple wireless presenter has limited functions of a pointing device such as "go to next slide" or "back to previous slide" in a specific application(Microsoft PowerPoint) through wireless channel; thus, there is inconvenience to do other tasks e.g., program execution, maximize/minimize window etc. provided by clicking mouse buttons. The main objective of this paper is to implement a multi-functional laser-pointer mouse that has the same functions of a computer mouse. In order to get position of laser spot in the projector display, an image processing to extract the laser spot in the camera image is required. In addition, we propose a transformation of the spot position into computer display coordinates to execute mouse functions on computer display.

This paper suggests the navigation information display system which is based on augmented reality technology and especially focuses on image analysis technology. Navigator has to always confirm the information from marine electronic navigation devices and then they compare with the view of outside targets of the windows. During this 'head down' posture, they feel uncomfortable and sometimes it cause near-accidents such as collision or missing objects, because he or she cannot keep an eye on the front view of windows. Augmented reality can display both of information of virtual and real in a single display. Therefore we tried to adapt the AR technology to help navigators and have been studied and developed image pre-processing module as a previous research already. To analysis the outside view of the bridge window, we have extracted navigational information from the camera image by using image processing. This paper mainly describes about recognizing ship feature by haar-like feature and filtering region of interest area by AIS data, which are to improve accuracy of the image analysis.

In retailing, it seems very important to examine how consumers perceive in store design factors such as instore space for walking, product arrangement styles, instore display types, window sizes, and possibly others. Furthermore, consumers perceptions of various designs would be differentiated by consumers shopping patterns such as actual shopping versus window shopping. This article empirically investigates how various desings create different consumer reactions measured by consumer mood and store image depending on the types of consumer shopping. It was found that design factors such as open, focused, and big would create better consumer mood and consumer perceptions of store image than closed, unfocused, and small. Another finding was that consumer perceptions would interact with consumer shopping patterns. Based on the research findings, some implications are discussed in the article.

Query-by-Example(QBE) is high-level display-oriented databased manipulation language that provides a convenient and unified style for querying, updating, defining, and controling a relational database. QBE is relationally complete. However, lack of aubquery constructs limits th usability of QBE significantly. In particular, certain queries cannot be represented in one window. In this paper, we define a subquery box and extend QBE for subquery construction. The Extended QBE makes it possible to represent the queries that the QBE cannot do in one window, reducing the overhead and complexity of composing those queries. We also define the grammar of the Extended QBE and present the parsing techniques. Finally, we present an algorithm to transform the queries in Exteded QBE to those in SQL. The result of the transformation can be executed using dynamic SQL features of any SQL system. The proposed language has been implemented on OS/2 using the OS/2 EE Database Manager.

The development of universal CCD camera control software for all BOAO CCD camera systems is proposed. The new software, running under Sun SPARCstation and motif based X window system with SunOS 4.1.3 operating system, replaces existing control software based on NeXTstation color and NeXTstep 2.1 operating system which is no more produced now. Several new features of the new software is introduced, some of which are 1) the image contrast is enhanced by color manipulation and display, 2) image zooming and trimming, 3) any size of image can be displayed in the scrolled window, and 4) the offset between telescope pointing position and CCD center is easily calculated by alt-azi map. Along with the above new features, the new software has advantages including ease of maintenance and upgrading and elimination of risk caused by hardware damage. Since September 1, the software beta version is being used by observers and there is not seen severe problem regarding the software itself, but several requests to equip more features to the software will be mirrored to future release.
