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.
The purpose of this paper is to report on the use of XML languages to support the TERESA tool. This is a tool for model-based design of multi-device interfaces. It considers three levels of abstractions (task model, abstract user interface and concrete user interface). For each of them a specific language has been defined and used. In addition, since the… (More)
This paper describes an environment able to support migratory multimodal interfaces in multidevice environments. We introduce the software architecture and the device-independent languages used by our tool, which provides services enabling users to freely move about, change device and continue the current task from the point where they left off in the… (More)
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)
The increasing availability of various types of interactive platforms has raised the need for design environments able to support development of user interfaces that exploit interaction modalities other than the traditional graphical interfaces. In this paper we present a model-based solution to help designers in the development of voice applications. In… (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)
Migratory user interfaces are particularly promising for forthcoming ubiquitous environments enabled by the evolution of wireless technology and the proliferation of a wide variety of interactive devices. In this paper we present a logical framework and some fundamental concepts and dimensions that can be useful to help user interface designers 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 , 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)
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 tool (TERESA), which can be helpful when designing applications accessible through various device types.
The increasing availability of new types of interaction platforms raises the need for new methods and tools to support development of nomadic applications. This paper presents a solution based on the use of multiple levels of abstractions and a number of transformations able to obtain concrete interfaces, taking into account the different platforms and… (More)
