Ευχρηστία και διαδίκτυο

Η αναγκαιότητα χρήσης του Internet στις μέρες μας είναι προφανής ακόμα και για ανθρώπους που δεν έχουν άμεση ή έμμεση σχέση με το αντικείμενο των Ηλεκτρονικών Υπολογιστών. Ο πλούτος της παρεχόμενης πληροφορίας, η αμεσότητα ενημέρωσης οι προσφερόμενες υπηρεσίες και τα εργαλεία που συγκροτούν την έννοια που αποκαλούμε συνολικά διαδίκτυο, προκαλεί δέος. Πολλοί μάλιστα μιλούν για "τεχνολογικό αποκλεισμό" σε περίπτωση που κάποιος δεν προσπαθήσει να προσαρμοστεί και να ενσωματώσει τη νέα αυτή πραγματικότητα στο τρόπο ζωής και εργασίας του. Προφανώς λοιπόν το έργο που έχει να επιτελέσει η επιστήμη της Ευχρηστίας Λογισμικού σε αυτό το τομέα είναι σημαντικό και θα πρέπει να γίνει κατανοητή από όλους μια πιο ανθρωποκεντρική θεώρηση της διαδικασίας σχεδιασμού και ανάπτυξης λογισμικού για το διαδίκτυο. Το Internet έχει αρχίσει να ενηλικιώνεται και πλέον πρέπει να βελτιωθεί με τέτοιο τρόπο ώστε να προάγει μια ευρύτερη ουμανιστική αντίληψη της χρήσης του υπολογιστή με κέντρο τον άνθρωπο και μέσο τον υπολογιστή που έχει σαν πάγιο στόχο να εξυπηρετήσει αρτιότερα, ταχύτερα, πιο ευχάριστα και πιο πλήρως τις ανάγκες του.

Altruistic vs. Narcissistic Web Sites

Users are repulsed by web sites that are narcissistic, egotistic, corporate-speak, hard to understand, and difficult to use. Users are attracted to and enjoy web sites that are altruistic, user-prioritized, user-focused, easy to understand, easy to use, and full of fresh, relevant content.

Analyzing Usability of a Beta-Version Web Site Through Server Logs, User Profile Data, and Online Questionnaire Responses  

This paper discusses the use of automated data collection to learn from hundreds of beta-test users of a web-based industrial product database how successfully the product met their needs. The collected data consisted of web server log data, opinion data from online questionnaires and follow-up interviews, and user profile data from telerecruiting and online registration was also collected. In the Proceedings of the 1998 Usability Professionals' Association Conference.

The Art of Being Human

Site visitors crave the sense that someone is there, within and behind your Web pages, your emails and newsletters. Dealing with the bare technology of online interactions is a cold experience for many, or even most of us. It makes us feel anxious. Technology isn't warm. It has no heart. It neither understands us, nor cares for us. For many Web sites, whether for businesses or organizations, we simply plug in and play the bare technology - the super-duper means of information delivery. All the site visitor sees and feels is the design, the interface, the links and the clicks. The experience is about as warm and human as banking with an ATM machine.

As Simple As Possible

The virtues of simplicity are well-known among experienced systems designers. And many of the things that are 'right' with simpler software systems are also applicable to Web pages and site designs.

Avoiding Bias from the Survivor Effect

Only a few of the survey sites we analyzed in 2000 are still around. We can safely assume that the surviving sites are not a random sample of the original group, but rather that significant differences exist between the sites that made it and those that died. Survival might be due partly to luck, but it is mainly a result of good management and an understanding of Internet fundamentals. Thus, the surviving sites are likely to be disproportionately clued-in about what it takes to run an online business.

Blah-Blah Text: Keep, Cut, or Kill?

Introductory text on Web pages is usually too long, so users skip it. But short intros can increase usability by explaining the remaining content's purpose.

Branding and Usability

Many web sites exist primarily to create or strengthen the brand for a product or service. We’re finding that a site’s usability can dramatically affect branding. And the graphical aspects of the site — such as logos or evocative pictures — have much less effect on branding than we expected.

Bridging the Designer–User Gap

Depending on how representative designers are of the target audience, a project might need more or less user testing. Still, usability concerns never go away completely.

Build a Cross-Platform Web Design Testing Station in Mac OS

Everybody talks about cross–platform testing, but nobody’s shown how to do it on a nuts–and–bolts level. Until now. Sciortino’s comprehensive tutorial for Mac–based web designers will set you up with the testing platform of your dreams. (’Nix and Windows users, we hope to do the same for you in a future issue.)

Building a Better Interface

If you build it, they may or may not come. But if they do come and you've built it badly, they almost certainly won't come back. While it's immensely difficult to figure out what makes a user bookmark a site, usability is a critical factor. Despite this, most Web builders spend far too little time thinking about this aspect of site design.

Case Study: Conducting Large-Scale Multi-User User Tests on the United Kingdom Air Defence Command and Control System    

IBM was contracted to provide a new Air Defence Command and Control (ADCC) system for the Royal Air Force. The IBM Human Factors (HF) team was responsible for the design of the operations room, workstations and the graphical user interfaces. Because the project was safety-related, IBM had to produce a safety case. One aspect of the safety case was a demonstration of the operational effectiveness of the new system. This paper is an in-depth case study of the user testing that was carried out to demonstrate the effectiveness of the system. Due to time constraints the HF team had to observe five participants working simultaneously. Further, to provide a realistic operational environment, up to twenty-eight operators were required for each test. The total effort for this activity was four person-years. The paper will detail the considerations, challenges and lessons learned in the creation and execution of these multi-user user tests.

Collecting Feedback From Users of an Archive (Reader Challenge)

The collective brainpower of the Internet is an awesome beast that used to manifest itself on Usenet newsgroups. Most of these groups have degenerated into spam, flames, and newbie ignorance. The Web has not yet evolved good ways of utilizing this power, since most so-called 'community' sites are equally degenerate.

Comparing the Usability of Three Dual-Language School Websites

This study evaluated the usability of three websites for Spanish-English Dual Language K-8 schools. Twelve participants (6 parents, 6 teachers) reviewed and performed tasks on the three public school websites. Site usability was determined through both objective and subjective measures, including task completion time, first-click, total number of pages visited, task success, perceived task difficulty, user satisfaction, and overall ranked preference. Results indicated that one site was preferred more than the others by both user groups and resulted in more efficient search behavior. Clear navigation, link terminology, and proper use of both languages were found to be critical factors contributing to the sites’ usability.
