Rudiments of rough sets

In this provocative book, Barwise and Perry tackle the slippery subject of \"meaning, \" a subject that has long vexed linguists, language philosophers, and logicians.

An end-user questionnaire to measure user experience quickly in a simple and immediate way while covering a preferably comprehensive impression of the product user experience was the goal of the reported construction process. An empirical approach for the item selection was used to ensure practical relevance of items. Usability experts collected terms and statements on user experience and usability, including `hard' as well as `soft' aspects. These statements were consolidated and transformed into a first questionnaire version containing 80 bipolar items. It was used to measure the user experience of software products in several empirical studies. Data were subjected to a factor analysis which resulted in the construction of a 26 item questionnaire including the six factors Attractiveness, Perspicuity, Efficiency, Dependability, Stimulation, and Novelty. Studies conducted for the original German questionnaire and an English version indicate a satisfactory level of reliability and construct validity.

Construction and Evaluation of a User Experience Questionnaire

In dem Workshop werden Einsatzmoglichkeiten von Methoden zur Analyse und Gestaltung ergonomischer Software im Rahmen des gesamten Entwicklungszyklus thematisiert. Im Schwerpunkt geht es darum, zu erortern, wann im Entwicklungszyklus ergonomische Gestaltung effektiv ansetzen sollte bzw. kann, welche Methoden diesbezuglich Verwendung finden konnen. Die Bearbeitung des Themas soll sich nicht auf die Softwaregestaltung im engeren Sinn („reine“ Produktgestaltung) beschranken, sondern auch den Entwicklungsprozes und (psychologische) Aspekte der Arbeitsgestaltung, die in Entwicklungsprojekten zu berucksichtigen sind, einbeziehen. Gegebenenfalls soll fur die angesprochenen Fragen Entwicklungsbedarf bestimmt werden.
