Goal: The use of an online game for learning in higher education aims to make complex theoretical knowledge more approachable. Permanent repetition will lead to a more in-depth learning. Objective: To gain insight into whether and to what extent, online games have the potential to contribute to student learning in higher education. Experimental Setting: The online game was used for the first ti...

The performance of interactive systems is determined in relation to the context in which the system and users interact for task execution. It is obvious that the significance and complexity of contextual information require systemic approaches for managing it in the design process. As the system complexity and diversity of types and ranges of use context increase, context sensitivity becomes a ...

Recently, design researchers have been interested in observation-analysis approach to study design activities. This is how the annotation and annotation tools have been introduced into the design research. This paper describes the annotation process as an approach in design activity studies and proposes a sequential structure for the annotation process. The research objective is to characterize...

This paper argues for a model-driven framework for integrating human interface engineering with software engineering. The usage-centered design process, a robust and proven process grounded in software engineering, is briefly described and contrasted with traditional user-centered approaches. The connections between the core models of usage-centered design and their software engineering counter...

Credit card fraud detection (CCFD) is important for protecting the cardholder’s property and reputation of banks. Class imbalance in credit transaction data a primary factor affecting classification performance current models. However, prior approaches are aimed at improving prediction accuracy minority class samples (fraudulent transactions), but this usually leads to significant drop model’s ...

Agile methods have proven their worth in keeping a development team focused on producing high-quality code quickly. But these methods generally have little to say about how to incorporate user-centered design techniques. Also the question has been raised whether agile methods can scale up to larger systems design. In this paper we show how one user-centered design method, Contextual Design, for...
