From user interface design to the support of intelligent and adaptive interfaces: an overhaul of user interface software infrastracture

Research on adaptive interfaces in the past has lacked support from user interface tools which allow interfaces to be easily created and modified. Also, current user interface tools provide no support for user models which can collect task-oriented information about users. Developing an adaptive interface requires a user model and an adaptation strategy. It also, however, requires a user interface which can be adapted. The latter task is often time-consuming, especially in relation to more sophisticated user interfaces.

The paper presents a user interface design environment, UIDE, which has a different software infrastracture. Designers use high-level specifications to create a model of an application and links from the application to various interface components. The model is the heart of all the design and run-time support in UIDE, including automatic dialog sequencing and help generation. UIDE provides automatic support for collecting task-oriented information about users, by the use of its high-level specifications in its application model as a basic construct for a user model. Some examples of adaptive interfaces and adaptive help are presented that use the information that is collectable in UIDE.

The um toolkit for cooperative user modelling

This paper gives an overview of the um toolkit: the philosophy underlying its design, examples of its use and discussion of the way it deals with some major issues in creating user modelling shells. The um toolkit has been developed to provide support for a variety of cooperative agents. An important element of its cooperativeness is due to its capacity to give users an understanding of their own user models. This paper describes two substantial but very different uses of the toolkit. The first involves a collection of coaching systems that help users learn more about their text editor. Experimental results suggest that the user model is associated with users learning more. The second is a movie advisor that uses a range of tools to construct and refine the user model and to filter a database of movies. Both these systems are built from combining tools in um. The paper describes several of the tools for constructing and refining user models. In addition it describes the user-model viewing tools and the way that these help users ensure their user models are correct. The paper also discusses the two central themes of the um work, the application of a tools approach to the design of a user modelling toolkit and the implications of making the user model accessible to its owner, the person modelled.

Rapid Prototyping of Adaptable User Interfaces

User interface adaptation has been proposed in recent years as a means to achieve personalized accessibility and usability of user interfaces. Related user interface architectures, as well as a variety of related development method and tools, have also been elaborated. Admittedly, however, despite the recognized validity of the approach, which has been proved in practice in a series of prototype systems, the wider adoption and uptake of user interface adaptation approaches are still limited. One of the identified obstacles is the complexity intrinsic in designing such interfaces and the need of radically revising the current user interface design practice to account for (a) the alternative designs required for adaptation, (b) the parameters involved in driving adaptations (i.e., selecting among alternatives at a given point during interaction), and (c) the logic of adaptation at runtime. This article proposes a twofold tool-based support strategy for user interface adaptation development, based on (a) an adaptation development toolkit and related widget library, which directly embeds lexical level adaptations into common interactive widgets, and (b) embedding such a library in a common integrated development environment, thus allowing designers to define and view alternative adaptations at design time and create adaptable user interfaces through traditional prototyping. The aforementioned approach has been implemented in the domain of adaptable applications for older users, producing tools that are currently in use in the development of a large suite of interactive applications in various domains. The approach presented in this article is claimed to be the first and so far unique supporting rapid prototyping of adaptable user interfaces, thus minimizing the divergence between typical development practices and user interface adaptation development.
