A system for dynamic adaptation of web interfaces based on user interaction requirements

Abstract

This article makes the proposal for a software architecture that allows dynamic adaptation of Web interfaces depending on user interaction requirements, giving special attention to individuals who have any kind of disability. This task is achieved through several transformations on visual aspects of the Web pages such as changes on the sizes of objects, colors, relative position of the elements or navigation device used. The system separates the functionality of a Web site and its interface at runtime to customize later some of the elements of the interface according to the characteristics of the individual, taking advantage of the widespread use of Web standards such as CSS so that it is not necessary to use any additional platform for the specification of the interface. User information will be updated continuously through the use of interface autonomous agents that store data about navigation process, performing corrective actions to allow dynamic adaptation to the changing conditions of the user. © 2008 Springer-Verlag Berlin Heidelberg.
