1. An EUD Approach to the Design of Educational Games

Author

Ardito, Carmelo and Lanzilotti, Rosa

Abstract

Distance education has experienced profound changes due to the introduction of new technologies, especially mobile devices of different types. It is necessary to define new learning techniques which are able to capture students' attention and to engage them in their learning activities, reducing problems like distraction generated by the use of the device itself and/or by the surrounding environment. Game-based learning is a valuable possibility. The excursion-game has been recently proposed to support pupils learning history during visits to historical sites; its goal is to make the visit and the overall experience of cultural heritage more engaging. This paper describes the approach followed in the design of the system implementing the excursion-game; it takes into account an end-user development perspective in order to allow domain experts, i.e., experts in history and cultural heritage, contributing to design excursion-games for a wide set of historical sites. (Contains 11 figures.)

Abstract

International audience; Human-Computer Interaction (HCI) research has been focusing on properties such as usability, accessibility, inclusive design, user experience. As new security risks are emerging with the continuous increase of Internet interconnections and the development of the Internet of Things, more recently security, trust and resilience have also become important for the development of interactive systems. Since users have been identified as one of the major security weaknesses in today’s technologies, HCI becomes a fundamental pillar for designing more secure (but still usable) systems. However, interactive system properties might overlap and sometimes create conflicts in user-centered development processes. For example, security could reduce system usability by placing a burden on users when they have to deal with passwords. The HCI research has provided several tools and techniques that can support designers in making decisions, but there are no “cookbooks”. This workshop promotes sharing of experiences in managing and resolving conflicts of multiple interactive system properties within the context of a user-centered design process. We are concerned by theories, methods and approaches for dealing with interactive system properties, managing potential conflicts and trade-offs. This workshop is organized by the IFIP WG 13.2 on Methodology for User-Centered System Design and the IFIP WG 13.5 on Human Error, Resilience, Reliability and Safety in System Development.

Abstract

Alphanumeric passwords are still the most common form of user authentication despite well-known usability issues. These issues, including weak composition and poor memorability, have been well-established across different user groups, yet users with dyslexia have not been studied despite making up approximately 10% of the population. In this paper, we focus on understanding the user authentication experiences of people with dyslexia (PwD) in order to better understanding their attitudes towards a graphical password system that may provide a more inclusive experience. Through interactive interviews, participants were encouraged to try three different knowledge-based authentication systems (PIN, password, and graphical password) and then discuss their strategies behind code composition. We found that PwD employed potentially dangerous workarounds when composing passwords, in particular an over-reliance on pattern-based composition. We report on how PwD do not immediately see the benefits of graphical passwords, but upon experiencing the mechanism we see opportunities for more inclusive authentication.

Abstract

International audience; Authentication is a security function, added on top of an interactive system, whose role is to reduce organizations and users’ risks to grant access to sensitive data or critical resources to unauthorized users. Such a security function interfere with users’ goals and tasks by adding articulatory activities, which affect each dimension of usability. In order to mitigate their negative effect on usability, security functions must be designed following a User Centered Approach. In order to ensure their efficiency in terms of security, security processes have to be followed. With this respect, this paper focuses on the representation of user tasks (using task modelling techniques) to be performed during authentication. For security aspects, we propose the use of an approach called “attack trees” which represents threats and their effect. To integrate both aspects in a single framework, we propose an extended task modelling technique that is able to represent explicitly security threats and their potential effect together with users’ tasks performed during authentication. We show how such models can be used to compare the usability and the security of different authentication mechanisms and to make explicit conflicts between these properties. We exemplify the use of the approach on two sophisticated authentication mechanisms demonstrating its applicability and its usefulness for representing and assessing in a single framework, usability and security of these security mechanism.
