“…Therefore, the usability practitioner often faces the situation that user data need to be collected even before a working system is available for testing. Prototype testing then becomes the method of choice, and surveys among usability practitioners prove that the method of iterative user testing with early prototypes is very common (Vredenburg et al, 2002). The main requirements for prototypes are low cost of production and sufficient similarity to the final product to reach valid test outcomes.…”

The aim of the study was to investigate the influence of perceived prototype fidelity in usability tests by comparing two prototypes that differed with respect to their perceived proximity to the final system. The impact of the perceived developmental stage of the product was examined for participants' performance, perceived usability, emotions and psychophysiology. Eighty participants were tested, operating an electronic city guide on a mobile phone. In a 2×2×2 mixed design, the system was either presented as an early prototype or as the final system. In addition, observer presence (no observers vs. three observers) and task difficulty (high vs. low) were experimentally manipulated. Overall, the findings did not indicate major differences for perceived prototype fidelity. However, an interaction between the observer presence and prototype fidelity indicated that the observer presence had a more negative impact on the performance when testing a final system than an early prototype. Furthermore, the observer presence resulted in a psychophysiological stress response. The findings suggest that test outcomes are quite robust against different prototype perceptions but that the observer presence needs careful consideration. RESEARCH HIGHLIGHTS• Performance, emotions and psychophysiology are not affected by stage of system development.• Observer presence in usability testing cause higher stress levels among participants.• Observers impair participants' performance more in final than in early system testing.• A single-item usability measure is more strongly affected by test instructions than a multiple-item scale.

Abstract-The seemingly 'magical' developments of the World Wide Web have challenged the computer science researchers, analysts, designers and developers to think outside the box and apply their creativity. One of the main sectors that have paid great attention to the World Wide Web is the advertisement sector. Online advertisement is known to be one of the major incomes for many companies, social networks and search engines online. This paper proposes a framework that provides adaptive advertisements to be displayed to online users based on their social network profiles via creating an individual user model for each user. The framework was built based on literature research and an exploratory study conducted with actual web users. The framework is a layered model, where each layer provides a different functionality, but works towards a homogenous outcome of adaptive ads.

“…The point of user-centered design is not just to create something that works but rather to create something that works for the intended user, something that is usable. Usable designs should "make it easy to determine what actions are possible at any moment; make things visible, including the conceptual model of the system, the alternative actions, and the results of actions; make it easy to evaluate the current state of the system; follow natural mappings between intentions and the required actions; between actions and the resulting effect; and between the information that is visible and the interpretation of the system state" (Norman, 1988, p. 188; see also Abras, Maloney-Krichmar, & Preece, 2004;Vredenbrurg et al, 2002). Usable designs created for the purpose of facilitating information practices have a specific purpose: they should make it easy for people (users) to find, choose, use, and share information.…”

The purpose of this article is to survey the landscape of user-centered design in LIS. We begin the article by exploring the history of the "user-centered paradigm," looking first at the historical schism between behavioral science and computer science, and then surveying some of the methods of user-centered design. In the next section we present examples of technological artifacts that reflect the basic functions of information systems-artifacts designed to collect, organize, and retrieve information-as a way to present some of the difficulties and opportunities that surround the creations of user-centered design. Specifically, we look at how user-centered design relates to personal collections, social bookmarking, finding aids, Web interface design, information architecture, visualization systems, and personalization and adaptive search. The article then steps back and looks at design through the wider lens of values, asking the question, how are users represented (or misrepresented) through cultural, ethical, and political forces that influence information system design? The article concludes with a summary of the major issues to emerge from our survey of the current state of user-centered design and from this we extract some key lessons vis à vis research and teaching in LIS.
