Usability is considered a relevant quality factor in video games. However, usability evaluations are usually performed too late in the game development lifecycle. We present a usability evaluation strategy that can be used in early stages of model-driven video game development approaches. The usability evaluation is based on a Video Game Usability Model, which extends the usability characterist...

This paper describes an experiment to investigate user perceptions of the usability and security of single-factor and two-factor authentication methods in automated telephone banking. In a controlled experiment with 62 banking customers a knowledge-based, single-factor authentication procedure, based on those commonly used in the financial services industry, was compared with a two-factor appro...

fifty years ago warren and root have introduced the shape factor. this fundamental parameter for modeling of naturally fractured reservoirs has been discussed stormily ever since. different definitions for shape factor have been suggested which all of them are heuristically based. recently, heinemann and mittermeir mathematically derived - based on the dual-continuum theorem assuming pseudo-ste...

Smart-card-based password authentication, known as twofactor authentication, is one of the most widely used security mechanisms to validate the legitimacy of a remote client, who must hold a valid smart card and the correct password in order to successfully login the server. So far the research on this domain has mainly focused on developing more secure, privacy-preserving and efficient protoco...

Usability is a significant factor in the creation of quality software products which is an important focus of the software engineering syllabus. Usability is also a significant factor in the study of Human-Computer Interaction (HCI). Despite the connection, software quality and the rigours of the software engineering discipline are not used in the teaching of HCI and visa versa. Consequently, s...

The growth in demand for interactive software system has increased greatly in recent years. But, most of the developed systems are failing due to not providing suitable interface. User interface is the only way by which user can interact with software system. The problem lying in the interface is related to the usability. Usability is regarded as important quality factor for developing the succ...
