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.

Design, implementation and evaluation of an adaptive user interface

Software systems developed in recent years are becoming increasingly powerful, but in most cases they tend to abandon the user to deal with the complexity of the system alone. There is an immense need for systems with individual, context-sensitive support. The paper discusses the development of such a support system with special focus on the user interface. The extension of an existing and complex program. Excel, to an adaptive and customizable system is described. This extension is called Flexcel, and it has been implemented and evaluated.

The primary aim of this extension is to provide a convenient environment for adapting Excel's user interface to particular users and their current tasks. For example, it allows the user to define new menu for actions that are frequently needed and normally require a tedious dialog step. Flexcel also analyzes the user's interaction style and presents adaptation suggestions. A critique component supports the user in his/her problem solving and learning activities related to the adaptability of Flexcel's user interface.

Using consensus methods to construct adaptive interfaces in multimodal web-based systems

This paper presents a concept of adaptive development of user interfaces in multimodal web-based systems. Today, it is crucial for general access web-based systems that the user interface is properly designed and adjusted to user needs and capabilities. It is believed that adaptive interfaces could offer a possible solution to this problem. Here, we introduce the notion of the user profile for classification, the interface profile for describing the system interface, and the compound usability measure for evaluation of the interface. Consensus-based methods are applied for constructing the interface profiles appropriate to classes of users.

A context-aware reminder system for elders based on fuzzy linguistic approach

To date, several reminder systems for elders have been developed, but when and how to prompt the reminding message has not been fully explored yet. This paper presents a context-aware system that provides reminding messages for elders based on fuzzy linguistic model in order to properly deliver a reminder in an appropriate time and way. By separating the user activity contexts and contexts utilized to trigger a reminder, it is much easier for the elderly or their care givers to schedule and maintain reminders. We first adopt a fuzzy linguistic model to determine the prompting level based on the interrupt degree of user current activity and the urgent level of to-be-prompt reminder. An adaptive mapping strategy is then presented to transfer the prompting level into machine-readable parameters. Finally, the proposed approach is verified through our system prototype and experiments.     

Adaptive personalized interfaces—A question of viability

It is widely accepted that interfaces between computers and users should differ to accommodate individual, or group, needs. One method of 'personalizing' an interface is to have the system form a limited model of the user and employ it to fashion the dialogue to his needs. Unfortunately, little is known about the effect of adaptation on the man-machine interface. Although obvious advantages accrue from 'personalized' interfaces, there are also obvious disadvantages to presenting users with a changing, adapting and perhaps apparently inconsistent interface. The goal of this work is to determine the viability of an adaptive interface through a human-factor pilot study of a simple, specially designed, interactive computer system. The system uses menu-driven selection to retrieve entries from a large ordered telephone directory. This simple task has several advantages: it is a realistic application area for interactive computers; plausible adaptive modelling methods exist and have been studied theoretically; and previous work has determined the best way to display the menus to users. The results of this empirical study support the use of adaptive user modelling. In the (admittedly highly constrained) example system, a computer interface can indeed adapt successfully to every user. Although it does not necessarily generalize to other user interfaces, the result supplies evidence to refute published objections to adaptive user modelling in general.     

User interface—application communication in the Chimera user interface management system

Until quite recently, perhaps the least appreciated part of user interface management system (UIMS) architecture has been the interface to the application. A number of approaches to interface-application communication have been attempted, but these have suffered as a result of being non-programmable, unstructured and/or static. This paper presents the user-interface-application communication system developed for the Chimera UIMS, which attempts to address these problems. This system enables interprocess communication between user interface and application via an explicit, programmable UIMS component—an application linkage, which is structured, dynamic and reconfigurable at run-time. The internal structure of the linkage is described, along with the mechanism for communication with dialogue control and application. An extensive example is developed in order to illustrate the communication process to and from the user via dialogue control and linkage to the application.
