Scenario based design (SBD) approach has been widely used to improve the user interface (UI) design of interactive systems. In this paper, the effectiveness of using the SBD approach is shown to improve the UI design of the Thunderbird email system. Firstly, an empirical evaluation of the system was performed based on the user comments. Then, a low fidelity prototype of the modified interfaces ...

In this paper, we discuss a neuroimaging experiment that employed a mission-based scenario (MBS) design, a new approach for designing experiments in simulated environments for human subjects [1]. This approach aims to enhance the realism of the Soldier-task-environment interaction by eliminating many of the tightly-scripted elements of a typical laboratory experiment; however, the absence of th...

In the domain of Ambient Intelligence, research goals are many times driven by scenarios that help envisage a world enriched by ambient, pervasive, intelligent services. So far, scenarios have most times presented the perception that one person has upon the system, with few details on how the system should work in the background in order to deal with realistic requirements. In this paper, start...

TV can be regarded as the most far-reaching media in Brazil. Its presence is noticed in 90% of Brazilian homes and it is the main source of information for a major part of the population. The moment of definition and consolidation of the digital TV technology provides us with a unique opportunity for analyzing and discussing this media accessibility. Making sure that TV contents and devices are...

Article history: Received 30 October 2010 Received in revised form 22 February 2011 Accepted 3 March 2011 Available online 31 March 2011 For meaningful scenarios, creative input concerning possible future trends is crucial. Herman Kahn, the father of modern scenario planning, underlined the importance of “thinking the unthinkable” in a significant scenario study. “Blessed with high intelligence...

The ‘scenario approach’ is an innovative technology that has been introduced to solve convex optimization problems with an infinite number of constraints, a class of problems which often occurs when dealingwith uncertainty. This technology relies on random sampling of constraints, and provides a powerful means for solving a variety of design problems in systems and control. The objective of thi...

Adequate data acquired through the Wizard of Oz experimental prototyping method are still crucial to the cost-effective development of advanced spoken language dialogue systems. One important source of data corruption is the unintended priming of subjects through the task scenario representations used in the experiments. The paper presents the three sets of development and test scenario represe...

A product with a long-life, such as a plant or ship, must be adaptable to future technology changes, regulations, and environmental changes. This paper proposes a design method for a future scenario embedded product to enhance a product’s adaptability to various changes during its lifetime. The design method derives a modular structure between platform modules as constant sub-system and option ...

This paper presents an application scenario in which knowledge-based and object oriented modeling techniques are applied and used in the analysis and design of complex, computer-based systems. The methodology is presented in the context of an operations automation and information management system in the electric utility operations problem domain. This system is referred to as OAS, for Operatio...

Through out the design process, designers have to consider the needs of potential users. This is particularly important, but rather harder, when the designers interact with the artefact to-be-designed using different senses or devices than the users, for example, when sighted designers are designing an artefact for use by blind users. In such cases, designers have to ensure that the methods use...
