Abstract-Older adults are the fastest growing segment of the population worldwide. This paper presents a evaluation of the user experience of two online web-banking sites from an older user's point of view. We therefore conducted a usability testing employing 12 older participants, in order to analyze the needs and issues faced by this user group when performing real-world tasks. The study involved six tasks which users were required to complete within a specific time. Most of the participants were interested in learning to use online banking. Our results show that older persons do not find web-banking sites easy or user-friendly. Our qualitative findings revealed that both of the web-banking sites we examined presented problems. Implications for the future include the need to redesign bank websites so as to include guidelines and other suggestions made in this study.

Abstract. This paper explores the effectiveness, efficiency and ease of use of two alternative interface interactions in a mobile tablet application. More specifically, the study employs a navigation task which novice users were required to complete by means of two types of main menu button, one utilizing text and the other utilizing a visual metaphor. Furthermore, little evidence exists on the effect of the use of metaphor on users of various ages and levels of computer experience. Our results show that young users prefer buttons that display a visual metaphor in the form of an icon, in contrast to older participants, who preferred the button that employed text. They also show that the users' performance is dependent upon age.

Abstract-New e-book readers and multifunctional mobile tablet devices are currently emerging, so bringing about a transition from printed to the electronic books. It is important to learn how usable these mobile devices are, by testing them on real users from various backgrounds. The paper presents a study which explores the perceived usability of two electronic reading devices, one dedicated reader and one multifunctional device. More specifically, the study employs eight tasks which users were required to complete within a specific time with two devices. Our results show that users functioned better on the multifunctional device in terms of performance measures, such as navigation, task difficulty and satisfaction.

Graphical user interfaces are an evolution of the command line user interfaces of the past. Graphical user interfaces allow users to interact with devices while using the metaphor of a desktop surface. As technology evolved, user interfaces became more elaborate, going through various design phases such as skeuomorphism and modern, flat design. User interfaces have become more simplified and use fewer non-essential design elements. This also allows for easier cross-platform development.  Due to the widespread adoption of technology, clear user interfaces that put usability first, have and will become very important in the years to come. We present the very beginnings of the GUI, its evolution through the years and finally focus on modern graphical user interfaces while also going over various problems
