In this paper I explore Fauconnier and Turner's (1998) conceptual blending as an evaluative technique for user interface design. Conceptual blending theory offers a rich model that may account for meaning construction and meaning elaboration in design. Blending has been used previously to analyze jokes (Coulson, 1995), metaphor (Fauconnier & Turner, 1998), and Hebrew verb morphology (Mandelblit...

Securing automated teller machines (ATMs), as critical and complex infrastructure, requires a precise understanding of the associated threats. This paper reports on the application of attack-defense trees to model and analyze the security of ATMs. We capture the most dangerous multi-stage attack scenarios applicable to ATM structures, and establish a practical experience report, where we reflec...

This paper presents a method and results of an ethnographic study aimed at building an understanding of Automatic Teller Machine (ATM) adoption in Mumbai, India. The study combined field observations and semi-structured interviews ðN 1⁄4 43Þ of early ATM adopters, bank customers who do not use ATMs, and people who used the ATM for the first time as part of our research. Data were analysed to id...

Testing often accounts for more than 50% of the required effort during system development. However, testing is often not well integrated with other development phases. One reason for this is that designers, developers and testers all use different languages and tools, making it difficult to communicate with each other and to exchange documents. The UML 2.0 Testing Profile bridges the gap betwee...

Fatigued bills have harmful influence on the daily operation of Automated Teller Machine(ATM). To make the classification of fatigued bills more efficient, the development of an automatic fatigued bill classification method is desirable. We propose a new method to estimate the fatigue level of bill from the feature-selected frequency band acoustic energy pattern of banking machines. By using a ...

Developing robust and refined measures to quantify strategic impacts is a major challenge facing researchers who seek to improve methods for information technology (IT) investment evaluation. This paper presents a means to test for parameter heterogeneity in a model which quantifies the strategic contribution of IT. An iterative "jackknife" procedure is used to diagnose if different local compe...

An experiment was conducted to test the relationships between users' perceptions of a computerized system's beauty and usability. The experiment used a computerized application as a surrogate for an Automated Teller Machine (ATM). Perceptions were elicited before and after the participants used the system. Pre-experimental measures indicate strong correlations between system's perceived aesthet...

An approach for guiding the construction of use case specifications is presented. A use case specification comprises contextual information of the use case, its change history, the complete graph of possible pathways, attached requirements and open issues. The proposed approach delivers a use case specification as an unambiguous natural language text. This is done by a stepwise and guided proce...
