title	SAUCI. Self-Adaptive User Computer Interfaces
source	Carnegie Mellon University,Pittsburgh
summary	Different approaches to the design of the human-computer interface have been taken in the past. These can be organized into four broad categories: tack-on; intuitive/empirical; formal; and conversational. There are several important interface design criteria that have never been adequately attained in any of these approaches. One is modularity, that is, maintaining a clear separation between the interface and its target system. A second criterion is self-adaptation, or the ability of the interface to modify its own behavior to suit a given individual user. Two further criteria relate to the interface's potential to guide users in performing typical high-level tasks on the target system and to provide intelligent advice on the use of that system. This research was focused on developing an integrated technique for achieving these four design criteria. To that end, an abstract architecture called SAUCI, or the Self-Adaptive User-Computer Interface, was proposed, embodying a knowledge-based, object-oriented approach to interface design. The foundation of this approach rests upon information encoded within sets of objects. This information includes separate knowledge bases describing the individual users, the commands of the target system, and the high-level tasks appropriate for that system. The behavior of the interface is controlled by various methods which call upon the knowledge bases in a rule-governed manner to decide what interface features should be present at each phase of the user's dialogue with the target system. To test the feasibility of the proposed architecture, a working interface was implemented on a Xerox 1108 computer in the LOOPS language, with a UNIX operating system running on a separate minicomputer as the target system. An empirical evaluation of this prototype revealed clear advantages over the standard interface. Closer examination pointed to each of the factors of modularity, task guidance, and user-tailored assistance as playing a significant role in these effects. A discussion of additional applications of this architecture and of areas for future development is offered as further evidence of the value of this approach as a general framework for human-computer interface design.

title	PRIVATE/UN-PRIVATE SPACE: Scenario-based Digital Design for Enhancing User Awareness
source	CAADRIA 2006 [Proceedings of the 11th International Conference on Computer Aided Architectural Design Research in Asia] Kumamoto (Japan) March 30th - April 2nd 2006, 601-603

summary	Context awareness is important for human senses of places as well as human computer interaction. The aim of this research paper is focusing on controlling the user's privacy in a smart space which is adaptive to different users for enhancing the user's awareness in his diary life. In Environmental Psychology, the definition of privacy is that an individual has the control of deciding what information of himself is released to others, and under how he interact with others. (Westin 1970) And privacy is categorized as the linguistic privacy and visual privacy. (Sundstorm 1986). Solutions for privacy control: Plan Layout, Vision Boundary, Access Control and Architecture Metaphor - the transmission of information is not ascertainable for every single user. Although information are shown in public, but information is implied by cues and symbols. Only a certain user or a group of users have access to the full context of information. The methodology is to form an analytic framework to study the relationship between information, user and activities by using the computational supports derived from KitchenSense, ConceptNet, Python, 3d Studio Max and Flash; and to record patterns built up by users' behaviour and actions. Furthermore, the scenario-based simulation can envision the real world conditions by adding interfaces for enhancing user awareness.

title	ADI : An Adaptive Database Interface for Dynamic Databases
source	ASME Symposium Proceedings on Knowledge based Expert Systems for Manufacturing. Anaheim, CA: American Society of Mechanical Engineers, Production Engineering Division, December, 1986. pp. 119-130. CADLINE has abstract only
summary	The operation of a manufacturing organization often depends on its underlying design and manufacturing databases. In a manufacturing environment, many users, both individuals and application programs, must have access to one or more of the organization's databases to provide, use, or modify data, to control information flow, and to facilitate information management. Such databases routinely undergo dynamic changes in both their content and their structure. These changes commonly result from the design of new products, the introduction of new materials, and the introduction of new machines and processes on the shop floor. Such continuing changes must be reflected in the database schemas and subsequently require that application programs be updated and that online users be educated on a continuous basis. The problem addressed in this paper is that it is difficult for users and application programs to get the information that they need, when they need it, from the multiple heterogeneous database management system (DBMS) environments that have evolved in design and manufacturing organizations. The solution proposed here is to build a general, extendable interface between database users and the many sources of data available to them. This in itself is not a new suggestion; a number of researchers have addressed portions of this problem. In general, the interfaces that they have developed to date are best suited to environments where the structure of the database is static and does not change over time. One of the things that this paper proposes that is different from existing work is an interface which handles the dynamic restructuring nature of manufacturing databases, enabling a user to obtain the most accurate and up to date information as the structure and content of the underlying databases change. Another unique aspect of the DBMS interface proposed herein is that the interface attempts to capture the knowledge that an experienced human user incorporates in his search for data in a database, i.e., it seeks to identify and use the generic knowledge needed to operate a DBMS. This knowledge is used by the interface to enable both the online users and the application programs to request data without knowing the data's location or precisely how to ask for it. Further, the interface makes use of mechanisms that allow the user to request data without knowing the exact identity of the required entities that are stored in the database

title	Layout Design Problems: Systematic Approaches
source	Computer-Aided Architectural Design Futures [CAAD Futures Conference Proceedings / ISBN 0-408-05300-3] Delft (The Netherlands), 18-19 September 1985, pp. 28-52
summary	The complexity of the layout design problems known as the 'spatial allocation problems' gave rise to several approaches, which can be generally classified into two main streams. The first attempts to use the computer to generate solutions of the building layout, while in the second, computers are used only to evaluate manually generated solutions. In both classes the generation or evaluation of the layout are performed systematically. Computer algorithms for 'spatial allocation problems' first appeared more than twenty-five years ago (Koopmans, 1957). From 1957 to 1970 over thirty different programs were developed for generating the floor plan layout automatically, as is summarized in CAP-Computer Architecture Program, Vol. 2 (Stewart et al., 1970). It seems that any architect who entered the area of CAAD felt that it was his responsibility to find a solution to this prime architectural problem. Most of the programs were developed for batch processing, and were run on a mainframe without any sophisticated input/output devices. It is interesting to mention that, because of the lack of these sophisticated input/output devices, early researchers used the approach of automatic generation of optimal or quasioptimal layout solution under given constraints. Gradually, we find a recession and slowdown in the development of computer programs for generation of layout solutions. With the improvement of interactive input/output devices and user interfaces, the inclination today is to develop integrated systems in which the architectural solution is obtained manually by the architect and is introduced to the computer for the appraisal of the designer's layout solution (Maver, 1977). The manmachine integrative systems could work well, but it seems that in most of the integrated systems today, and in the commercial ones in particular, there is no route to any appraisal technique of the layout problem. Without any evaluation techniques in commercial integrated systems it seems that the geometrical database exists Just to create working drawings and sometimes also perspectives.

summary	Since mid 1990s internet has been developing rapidly to become the most booming and emerging media in late history and play an important role in living. Therefore, how to design an interface of easy to use has become an important issue pertaining to Human Computer Interaction. Norman (1986) proposed in the human computer interaction, there is a design model in the mind of designer. In turn, the designer will follow design model and to design a set of system image that is functional, learnable, and usable. Therefore, we want to understand the critical factor of influencing toward website construction, we should find out the mental model that web design team at first. In this paper, we using the Interactive Qualitative Analysis (IQA) approach. The data collection method of the participant of the focus group’s silent brainstorming is adopted. Further analyze web design team’s the conceptual model on website construction through inductive coding and axial coding. The result shows the affinities of 9 web design team is thus produced. And, Business Decision, Team Performance, Self-Fulfillment and Entrepreneur Communication are main influence factor. These factors can lead trend and goal of a website.

title	A Format for a Graphical Communications Protocol
source	IEEE Computer Graphics and Applications vol. 6.no. 3 (March, 1986): pp. 52-62
summary	This article describes the requirements for a graphical format on which a graphical on-line communications protocol can be based. It is argued that on-line graphical communications is similar to graphical session capture, and thus the author proposes an interactive graphical communications format using the GKSM session metafile. The discussion includes items that complement the GKSM metafile such as a format for on-line interactive exchange. One key application area of such a format is multimedia on-line conferencing. Therefore, a conferencing software architecture for processing the proposed format is presented. This format specification is made available to those planning multimedia conferencing systems

title	Three-dimensional Input and Visualization
source	Computer-Aided Architectural Design Futures [CAAD Futures Conference Proceedings / ISBN 0-408-05300-3] Delft (The Netherlands), 18-19 September 1985, pp. 68-84
summary	The aim of this chapter is to investigate techniques by which man-computer interaction could be improved, specifically in the context of architectural applications of CAD. In this application the object being designed is often an assembly of defined components. Even if the building is not actually fabricated from such components, it is usually conceptualized in these terms. In a conventional graphics- based CAD system these components are usually represented by graphical icons which are displayed on the graphics screen and arranged by the user. The system described here consists of three- dimensional modelling elements which the user physically assembles to form his design. Unlike conventional architectural models which are static (i.e. cannot be changed by the users) and passive (i.e. cannot be read by a CAD system), this model is both 'user generated' and 'machine readable'. The user can create, edit and view the model by simple, natural modelling activities and without the need to learn complex operating commands often associated with CAD systems. In particular, the user can view the model, altering his viewpoint and focus of attention in a completely natural way. Conventional computer graphics within an associated CAD system are used to represent the detailed geometry which the different three-dimensional icons may represent. In addition, computer graphics are also used to present the output of the performance attributes of the objects being modelled. In the architectural application described in this chapter an energy- balance evaluation is displayed for a building designed using the modelling device. While this system is not intended to offer a completely free-form input facility it can be considered to be a specialist man-machine interface of particular relevance to architects or engineers.

title	ADAM - Architectural Design Applications Model
source	ACADIA Workshop ‘86 Proceedings - Houston (Texas - USA) 24-26 October 1986, pp. 37-54
doi	https://doi.org/10.52842/conf.acadia.1986.037
summary	This paper will describe ADAM, a project to explore the potential for interfacing independent graphics software for the purpose of developing a microcomputer based design system. This system will be implemented in three undergraduate design studios at the University of Illinois (Urbana-Champaign) School of Architecture. The three design studios are part of an experimental project to determine the usefulness of computers in the architectural design curriculum. The concept used throughout the design of this system is: "make use of what already exists, but use it smoothly together in such a way that the management system is totally invisible to the user." Many low- end quality graphics software packages are commercially available. Each has the capacity to address some aspect of the architectural design process, none will do it all . The problem is a lack of compatibility between software. ADAM is a management system designed to invisibly control and interface the use of an assembly of graphics programs and data base management systems to achieve compatibility. Because of these compatible interfaces, new and varied design tools can be created from existing software..

title	Walkthrough - A Dynamic Graphics System for Simulating Virtual Buildings
source	Proceedings 1986 Workshop on Interactive 3D Graphics. ACM: 9-22
summary	As part of our graphics research into virtual worlds, we are building a tool for an architect and his client to use for rapid prototyping of buildings by visually "walking through" them in order to refine specifications. Our first prototype simulated the new UNC Computer Science building with some 8000 polygons. BSP-tree software on the Adage Ikonas gave a colored, shaded perspective view every 3-5 seconds while the user moved a cursor in real-time over floorplans shown on the Vector-General 3300. The current (third) version uses Pixel-Planes to generate 9 updates/second, view images shown 4' x 6' by projector. Active short- and long-term research questions include speed-up, stereo, a 6-DoF interface with eye-level defaults, and an interactive model-building, model-changing system.

title	GCI : A Tool for Developing Interactive CAD User Interfaces
source	26 p. : ill. Israel: 1986? includes bibliography
summary	GCI is a Unix based tool for developing interactive CAD programs. By separating command/menu definitions from the program, GCI makes it easier to change and extend the user interface. The language provided by GCI is used to define syntax of commands, menus, messages, and help text. Generally, GCI supports a static hierarchical structure of commands and menus. However, through a program interface, an application program has the freedom to change environments, commands and menus. This flexibility of run-time control of the user interface is essential for developing highly responsive interfaces in a CAD environment. This paper presents the main concepts and definition language of GCI. It then discusses architectural and implementation issues, and finally presents a typical application's view of using the tool

title	Windowing and Clipping -- - Chapter 6
source	Computer Graphics. Englewood Cliffs, NJ.: Prentice Hall, 1986. pp. 123-141 : ill. includes a short bibliography
summary	Applications programs define pictures in a world coordinate system. This can be any Cartesian coordinate system that a user finds convenient. Pictures defined in world coordinates are then mapped by the graphics system into device coordinates. Typically, a graphics package allows a user to specify which area of the picture definition is to be displayed and where it is to be placed on the display device. A single area could be chosen for display, or several areas could be selected. These areas can be placed in separate display locations, or one area can serve as a small insert into a larger area. This transformation process involves operations for translating and scaling selected areas and for deleting picture parts outside the areas. These operations are referred to as windowing and clipping

source	Computer Aided Design May, 1986. vol. 18: pp. 188-192 : ill. includes bibliography.
summary	A user-friendly 'divide-and-conquer' algorithm, which finishes quickly, is presented for finding all the intersection curves between two parametric surfaces in the Bernstein-Bezier representation. The underlying idea of the algorithm is to deal with the Bezier net instead of the surface description itself. By alternately subdividing the Bezier nets, and estimating the intersection area, a finite element mesh is created in the intersection region of the surfaces. The intersection is approximated by polygons computed by plane-plane-intersections using planes defined by Bezier points of the refined Bezier nets. Contour lines can also be produced by the algorithm

summary	User Interface Management System (UIMS) called MIKE that does not use the syntactic specifications found in most UIMSs is described. Instead, MIKE provides a default syntax that is automatically generated from the definition of the semantic commands that the interaction is to support. The default syntax is refined using an interface editor that allows modification of the representation of the interface. It is shown how active pictures can be created by adding action expressions to the viewports of MIKE's windowing system. The implications of MIKE's command based dialogue description are discussed in terms of extensible interfaces, device and dialogue-style independence, and system support functions

summary	Computer technology and CAD are about to change radically the thousands of years of tradition of the architect's work. We are leaving behind the old method of drawing by hand, replacing the pencil with a stylus for pointing elements of mathematical models of projects. We are changing over from two dimensional to three dimensional design. Decisive for the architect to achieve a successful outcome has always been and will always be the visualisation of the project right from its early stages. There is a trend in our time and a risk in the new technology of fragmenting our work and making it more abstract. The new technology is based on the old one and in the beginning its user still has the habits of the old. Therefore the visualisation in present CAD systems and three dimensional design is based on the old plan projections; axonometrics and perspectives. However, there is an essentially better way which happens also to be natural to the new technology and simple to realize using it. This is the spherical projection.
