The ever-increasing availability of new types of devices raises a number of issues for user interface designers and interactive software developers. We have designed and developed a model-based authoring environment (TERESA), which provides support when designing and developing interfaces accessible through various device types in Web-based environment.
1. ABSTRACT Natural development aims to ease the development process of interactive software systems. This can be obtained through the use of familiar representations and intelligent environments able to map them onto corresponding implementations of interactive systems. The main motivation for model-based approaches to user interface design has been to(More)
This paper presents our solution to supporting runtime migration of Web application interfaces among devices offering different interaction modalities, in particular graphic to vocal platform migration and vice versa. Migrating between platforms implies keeping track of the user interactions in order to retrieve the runtime state of the interface and(More)
A goal of natural development is to ease the building of interactive software systems. Some work has been dedicated to obtaining natural programming [3], which aims to support programming through languages understandable by people without any specific programming skills. On one hand, natural development implies that people should be able to work through(More)
While new solutions for supporting migratory interfaces are emerging , there is still a lack of analysis of their impact on users. In this paper we discuss the design of a solution for trans-modal migratory interfaces in multi-device and results obtained testing it with users. We conducted a study aimed at evaluating the user impact of a migration service(More)
