Testing And Evaluation

Usability testing is a process that employs a sample of future users to evaluate software according to specific usability criteria. With the unprecedented growth and reach of the Internet, it is hard to reach representative users of Websites across the world. The new branch of remote usability testing has emerged as an alternative. While it is prohibitively expensive to conduct usability testing on a global range of users, it is technically possible and is more feasible to remotely collect the necessary information about usability problems and to analyze them the same way we do local tests. In this chapter, we present systematic methods and tools to support remote usability testing and evaluation of Web interfaces.

The primary objective of this study is to determine the usability of the Newspaper-on- DVD project of the Rizal Library, Ateneo de Manila University and to make recommendations that will help improve the system and expand its usage. In 2000, Library started transforming the preserved newspaper from microfilm to digital images. The library then provided an easier mode of access by providing a search tool that will link the index to the images and to the printers. A descriptive evaluative research method through usability testing was used in this study. Ten representative students were asked to complete a series of tasks using NP-DVD. Based on the test, the researcher was able to identify usability problems and recommended futures actions to enhance the system. These problems characterize the difficulties users face while using library search tools available not only in the libraries but also in the internet.

Methodological Guidelines

User interfaces of computer applications encompass a number of objects such as navigation links, buttons, icons, and thumbnails. In this chapter, these are called interface signs. The content and functions of a computer application are generally directed by interface signs to provide the system’s logic to the end users. The interface signs of a usable application need to be intuitive to end users and therefore a necessary part of usability evaluation. Assessing sign intuitiveness can be achieved through a semiotic analysis. This study demonstrates how a semiotic assessment of interface signs’ intuitiveness yielded a number of benefits. For instance, (i) it provides an overall idea of interface signs’ intuitiveness to the end users to interpret the meaning of interface signs, (ii) it assists in finding usability problems and also in (iii) recommending possible solutions, (iv) provides background for introducing guidelines to design user-intuitive interface signs, (v) helps in constructing heuristic checklist from semiotics perspective to evaluate an application, (vi) no additional resource and extra budget are needed. This study also presents a list of methodological guidelines to obtain the perceived benefits of integrating semiotic perception in usability testing for practitioners.

This research aims to suggest key design characteristics that are necessary for developing usable e-commerce websites in the Arab world. A comprehensive usability evaluation of four leading Arab e-commerce websites was conducted using the heuristic evaluation method. The results identified major and minor usability problems and major and minor good design characteristics on the selected websites. Based on the results, 51 key design characteristics were suggested. The recommended key design characteristics comprised two levels according to their priority: level one which includes mandatory key design characteristics and level two which includes supplementary design characteristics. The key design characteristics in each level were categorized under specific pages and areas that can be found on any e-commerce website. Such categorizations could direct website evaluators and designers to important pages and areas that should be considered to improve the overall usability of e-commerce websites. The results of this research are particularly important to developing countries which are still facing challenges that may affect the design and accessibility of usable and useful websites. These relate to low speed of accessing the Internet and a lack of website designers who have experience in customers’ needs and websites’ usable design characteristics.

Remote Usability Testing

Fifteen usability professionals participated in a usability test under one of three simulated real time viewing conditions: (1) Screen data (S) where the evaluators saw only the image of the user's computer screen; (2) Screen plus Audio data (SA) where the user's verbalizations could be heard in addition to viewing the screen image; and (3) Screen plus Audio plus Video data (SAV) where the evaluator's additionally saw an image of the user's face in real time. Results indicated no significant differences in the total number of problems found under the three viewing conditions although there was some evidence that the problem space differed particularly from the subjective questionnaire data collected directly from the users. In rating the severity of the problems encountered, the agreement among the usability professionals was low and did not vary as a function of the number of years of the usability professional's experience. More importantly, however, ratings of severity varied as a function of viewing condition with those usability professionals in the face condition perceiving the same problems to be more severe. When considering only the most severe problems (on which there was agreement in severity ratings), the number of severe problems uncovered was less with the questionnaires than under the three real-time viewing conditions. The results are discussed in terms of real time usability evaluation and terms of the implications for remote usability testing.

<p>Student Centered e-Learning Environment (SCeLE) has substantial roles to support learning activities at Faculty of Computer Science, Universitas Indonesia (Fasilkom UI). Although it has been used for about 10 years, the usability aspect of SCeLE as an e-Learning system has not been evaluated. Therefore, the usability aspects of SCeLE Fasilkom UI as a learning support system and what makes SCeLE Fasilkom UI an ideal system are not known yet. Motivated by the mentioned conditions, the researchers found an urge to conduct a usability evaluation in order to propose a set of recommendation for SCeLE usability improvement, based on usability evaluation reflecting both students and lecturers experience as user.</p><p>In this present research, the usability testing was conducted for SCeLE, targeting learning activities underwent by undergraduate students at Fasilkom UI, in the form of blended mode online learning. The data collection stage in the usability testing was performed by distributing questionnaire to students and interviewing several lecturers and students. The collected data was then analyzed and interpreted to obtain usability problems and solution alternatives. The quantitative data was analyzed using central tendency as reference, while the qualitative data was analyzed using theme-based content analysis. Data interpretation was performed by determining how to handle each kind of data based on the theme, and classifying each of the identified usability problem based on its severity rating.</p><p>The recommendations constructed to solve the usability problems were based on solution alternatives from the analyzed data supported by literature study. The present research comes up with seven main recommendations and an extra recommendation. The main recommendations are solutions to tackle the identified usability problems, while the extra recommendation is not directly related to any of identified usability problems, but was considered potential to improve the SCeLE usability.<br /><br /></p>

The Information SuperHighway, Email, The Internet, FTP, BBS, Modems, : all buzz words which are becoming more and more routine in our daily life. Confusing terminology? Hopefully it won't be in a few minutes, all you need is to have a handle on a few basic concepts and terms and you will be on-line with the rest of the "telecommunication experts". These terms all refer to some type or aspect of tools associated with a range of computer-based communication software and hardware. They are in fact far less complex than the instruments we use on a day to day basis as microscopist's and microanalyst's. The key is for each of us to know what each is and how to make use of the wealth of information which they can make available to us for the asking. Basically all of these items relate to mechanisms and protocols by which we as scientists can easily exchange information rapidly and efficiently to colleagues in the office down the hall, or half-way around the world using computers and various communications media. The purpose of this tutorial/paper is to outline and demonstrate the basic ideas of some of the major information systems available to all of us today. For the sake of simplicity we will break this presentation down into two distinct (but as we shall see later connected) areas: telecommunications over conventional phone lines, and telecommunications by computer networks. Live tutorial/demonstrations of both procedures will be presented in the Computer Workshop/Software Exchange during the course of the meeting.
