This paper present a heuristic model to ease scenario construction and usage in interaction design processes. We argue that the role of scenarios varies: I) along the design process, thus scenario building and usage have to be attuned to the particular goal of the design phase; II) in respect to the people that will use them (e.g., design team, client, user), thereby scenarios have to suit in s...

User-involvement and consensus building are thought to be a key process to achieve high satisfaction in planning and implementing social infrastructures and related services and plans. In products and information system development, an iterative Human-centered Design process starting from observing users behavior are applied, but not implemented in the areas above is known to provide effective ...

The elicitation, modeling and analysis of requirements have consistently been one of the main challenges during the development of complex systems. Telecommunication systems belong to this category of systems due to the worldwide distribution and the heterogeneity of today’s telecommunication networks. Scenarios and use cases have become popular for capturing and analyzing requirements. However...

construction industry consists of several phases in which a variety of stakeholders are involved. as construction projects are becoming larger, more complex and more diverse, the design phase has been more important factor for the success of projects than ever before. however, it is considered that most of design work occurred in actual design process is intangible. such recognition makes the d...

The purpose of this study is to understand the reaction of real estate prices to changes in different factors. In order to achieve this, a previously developed system dynamics model of real estate prices in Istanbul has been used (Özbaş and Özgün, 2005). The model has been developed and scenario analysis is carried out to some extent. However, a structured experimental analysis of the model und...

We introduce our human-centered approach for designing a ubiquitous computing system which aims at providing a better experience for shoppers at a supermarket. We investigated grocery shopping processes by using ethnographic research techniques and understood the processes with details. Further, we constructed Three-Phase Model, or TPM, which describes a shopper’s behaviors and various states o...

Nowadays, embedded systems need to support multiple applications simultaneously. It is not enough anymore to simply use a mobile phone to call somebody, but users also want to be able to simultaneously do other things, like listen to mp3’s or watch videos. This calls for a change in embedded system design which already takes the interaction between the multiple applications into account in the ...

In 2005, the initial version of CyberCIEGE, a network security simulation packaged as a video game, was released. Since then, we have developed a suite of game scenarios and have enhanced and extended the underlying game engine to cover a broad set of cybersecurity concepts. CyberCIEGE includes a Scenario Development Kit to customize existing game scenarios and create new ones. A Scenario Devel...
