Direct Combination

2004

Direct Combination is a user interaction framework that can be applied to desktop computing and to mobile and ubiquitous computing to lessen the user's need to search the user interface in certain circumstances. This paper investigates various ways of extending Direct Combination, including recursion, composition, abstract objects, and ambient combination afforded by hand gestures. This paper assumes that the reader is already familiar with the basics of Direct Combination.

Interface developers combine interaction elements in order to implement the User Interface of interactive software applications, using the development facilities available by a given development tool. The functional capabilities of the interface tool may significantly affect the quality of the resulting interactive software product, as well as the resources needed for further maintenance, upgrade, porting and expansion. Interaction objects play a key role in interface tools, irrespective of the nature of the interface construction technique (e.g. graphical construction, programming language, declarative specification, task notation). We have identified four fundamental categories of mechanisms for manipulating interaction objects in interface tools. Their merits in the context of interface development tools are identified, particularly in the context of developments for diverse user groups and openness for different interaction technologies. We will also show that these two function...

Abstract Direct manipulation has been lauded as a good form of interface design, and some interfaces that have this property have been well received by users. In this article we seek a cognitive account of both the advantages and disadvantages of direct manipulation interfaces. We identify two underlying phenomena that give rise to the feeling of directness. One deals with the information processing distance between the user's intentions and the facilities provided by the machine.

Our work focuses on the design of interaction techniques for large information spaces. Our goal is not to define yet another visualization technique but to provide insights for the design of such techniques. Our design approach is based on ergonomic criteria that arose from a study of how the user perceives and manipulates a large information space. We then provide design rules that should help the designer in devising an interaction technique that verifies the ergonomic criteria. After the design of the interaction technique, the next step is software design. We establish links between our design rules/ergonomic criteria and the software architecture model. By applying our PAC-Amodeus model, we show how the software architecture model helps to either verify or assess the ergonomic criteria. We therefore adopt a predictive evaluation approach to the design of interaction techniques for large information spaces. We illustrate our design approach and results through our VITESSE system.

The field of human-centered computing has known a major progress these past few years. It is admitted that this field is multidisciplinary and that the human is the core of the system. It shows two matters of concern: multidisciplinary and human. The first one reveals that each discipline plays an important role in the global research and that the collaboration between everyone is needed. The second one explains that a growing number of researches aims at making the human commitment degree increase by giving him/her a decisive role in the human-machine interaction. This paper focuses on these both concerns and presents MICE (Machines Interaction Control in their Environment) which is a system where the human is the one who makes the decisions to manage the interaction with the machines. In an ambient context, the human can decide of objects actions by creating interaction scenarios with a new visual programming language: scenL.

This paper presents the notion of (user interface development) platform administration and argues for its increasing importance in the context of modern interactive applications. Platform administration entails strategies for manipulating diverse interaction components. Four such strategies are elaborated-namely augmentation, expansion, integration and abstraction-which collectively constitute the ingredients of a platform administration process. The paper describes both the rationale for these strategies in the context of user interface development and their implementation details, as currently realized in an ongoing R&D project.

Although there has been important progress in models and packages for the output of graphics to computer screens, there has been little change in the way that input from the mouse, keyboard, and other input devices is handled. New graphics standards are still using a fifteen-year-old model even though it is widely accepted as inadequate, and most modern window managers simply return a stream of low-level, device-dependent input events. This paper presents a new model that handles input devices for highly interactive, direct manipulation, graphical user interfaces, which could be used in future toolkits, window managers, and graphics standards. This model encapsulates interactive behaviors into a few "Interactor" object types. Application programs can then create instances of these Interactor objects which hide the details of the underlying window manager events. In addition, Interactors allow a clean separation between the input handling, the graphics, and the application programs. This model has been extensively used as part of the Garnet system and has proven to be convenient, efficient, and easy to learn.

Abstract Software engineers are often called upon to design user interfaces, but strategies and guidelines are only beginning to emerge. Shneiderman (1983) introduced the term" Direct Manipulation" to describe user interfaces which have: 1) continuous representation of the objects of interest. 2) physical actions (movement and selection by mouse, joystick, touch screen, etc.) or labeled button presses instead of complex Syntax. 3) rapid, incremental, reversible operations whose impact on the object of interest is immediately visible.
