Usability ist üblicherweise in Bezug zu anderen Faktoren beschrieben. Vier dieser fünf häufigen Faktoren hat Nielsen bereits 1993 definiert - die Determinante Einprägsamkeit (Memorability) wird von einigen Forschern außen vor gelassen. Die anderen vier werden von vielen anerkannten Wissenschaftlern auf dem Human-Computer-Interaction. Gemäss Nielsen (1993) beinhaltet der Begriff der Usability die Bestandteile acceptability, usefulness und utility (Leistungsumfang eines Systems). Iin diesem Zusammenhang sind die Erlernbarkeit, die Effizienz, der Wiedererkennungswert, die Fehlerrate und die Befriedigung der Nutzerbedürfnisse von besonderer Bedeutung For 11 studies, we find that the detection of usability problems as a function of number of users tested or heuristic evaluators employed is well modeled as a Poisson process. The model can be used to plan the amount of evaluation required to achieve desired levels of thoroughness or benefits. Results of early tests can provide estimates of the number of problems left to be found and the.

The usability expert Jakob Nielsen is a leader in the field of usability engineering. In his 1993 book Usability Engineering , Nielsen describes methods to use throughout a product development process—so designers can ensure they take into account the most important barriers to learnability, efficiency, memorability, error-free use, and subjective satisfaction before implementing the product Bei der heuristischen Evaluation untersucht eine geringe Zahl an Gutachtern (empfohlen werden 3-6, Nielsen, 1992, Finding usability problems through heuristic evaluation. Proceedings ACM CHI'92 Conference (Monterey, CA, May 3-7), 373-380.) die Software auf Übereinstimmung mit bestimmten Usability Prinzipien (Heuristiken) Nielsen defined a model of the attributes of system acceptability (Neilsen 1993), and this was tailored further in defining usability in mobile handsets (Ketola and Roykkee 2001). Generally. Usability is the measure of the quality of the user experience when interacting with something - whether a web site, a traditional software application, or any other device the user can operate in some way or another. Basically usability is concerned with making systems easy to learn and easy to use. (Nielsen 1993, S.23 Jakob Nielsen is a principal of Nielsen Norman Group.

Menurut Nielsen (1993), usability adalah ukuran kualitas pengalaman pengguna ketika berinteraksi dengan produk atau sistem apakah situs web, aplikasi perangkat lunak, teknologi bergerak, maupun peralatan-peralatan lain yang dioperasikan oleh pengguna. Menurut Han, dkk (2000), usability adalah derajat keefisienan dan keefektifan penggunaan di antara pengguna, tugas, peralatan dan lingkungan.

According to Jakob Nielsen (1993), thinking aloud may be the single most valuable usability engineering method (p. 195). In a think-aloud user study, a single participant is tested at any given time. The participant narrates what he or she is doing, feeling, and thinking while looking at a prototype (or fully functional system) or completing a task. This method can seem unnatural for. Nielsen, 1993; S. 58-59). Für die Darstellung werden meist Metaphern verwendet. Bei den Betriebssystemen Mac OS und Windows wurde auf die Schreib-tisch-Metapher zurückgegriffen. Ein virtueller Ordner stellt eine Sammlung von einzelnen Dateien dar, ähnlich einem Aktenordner in : einem realen Büro. Der Schreibtisch wird zum Desktop. Der Papierkorb dient zum Löschen einer Datei analog einem. In einem Experiment zeigt Nielsen (1993), daß Usability Experten mit Hilfe Heuristischer Evaluation mehr Probleme identifizieren als normale Anwender. Sog.

According to the authors, the formula is based on the Poisson model. Also, according to the results of the experiments, Laundaure and Nielsen say, that the average probability of detecting problems in one test will be around 30%.

The discount usability engineering method (Nielsen, 1993, p. 17) uses four techniques: user and task observation, scenarios, simplified thinking aloud and heuristic evaluation. Nielsen (1994b, p. 58) suggests that there are two major reasons for alternating between heuristic evaluation and user testing. First, heuristic evaluation does not require users, who can be hard to get, and can be used. For example, Nielsen (1993) argues that for usability engineering purposes, one often needs to draw important conclusions on the basis of fairly unreliable data, and one should certainly do so since some data is better than no data (p. 166). However, others (e.g., Woolrych & Cockton, 2001) may question the wisdom of this advice; they may argue that it is invalid to draw any conclusions.

Usability heuristics (Nielsen, 1993). • Usability principles (Constantine and Lockwood, 1999). • Evaluation check list for software inspection (Ravden and Johnson, 1989). • Guidelines on user interaction design (Hix and Hartson, 1993). • Seven principles that make difficult task easy (Norman, 1988). Usability studies are commonly used in industry and applied in research as a yardstick for other usability evaluation methods. Though usability studies have been studied extensively, one potential threat to their reliability has been left virtually untouched: the evaluator effect. In this study, four evaluators individually analyzed four videotaped usability test sessions. Only 20% of the 93. Nielsen, J. (1993). Usability Engineering, Cambridge, MA: Academic Press Noverant, M.

The identification of usability problems is the key output of this type of usability test (Nielsen, 1993; Rubin & Chisnell, 1994).
