-Questionnaires are a cheap and highly efficient tool for achieving a quantitative measure of a product's user experience (UX). However, it is not always easy to decide, if a questionnaire result can really show whether a product satisfies this quality aspect. So a benchmark is useful. It allows comparing the results of one product to a large set of other products. In this paper we describe a benchmark for the User Experience Questionnaire (UEQ), a widely used evaluation tool for interactive products. We also describe how the benchmark can be applied to the quality assurance process for concrete projects.

The user experience questionnaire (UEQ) is a widely used questionnaire to measure the subjective impression of users towards the user experience of products. The UEQ is a semantic differential with 26 items. Filling out the UEQ takes approximately 3-5 minutes, i.e. the UEQ is already reasonably efficient concerning the time required to answer all items. However, there exist several valid application scenarios, where filling out the entire UEQ appears impractical. This paper deals with the creation of an 8 item short version of the UEQ, which is optimized for these specific application scenarios. First validations of this short version are also described.

Abstract.A good user experience is central for the success of interactive products. To improve products concerning these quality aspects it is thus also important to be able to measure user experience in an efficient and reliable way. But measuring user experience is not an end in itself. Several different questions can be the reason behind the wish to measure the user experience of a product quantitatively. We discuss several typical questions associated with the measurement of user experience and we show how these questions can be answered with a questionnaire with relatively low effort. In this paper the user experience questionnaire UEQ is used, but the general approach may be transferred to other questionnaires as well.

-Developer, manager and user feedback is needed to optimize products. Besides the basic Software qualities -usability and user experience are important properties for improving your product.Usability is well known and can be tested with e.g. a usability test or an expert review. In contrast user experience describes the whole impact a product has on the end-user. The timeline goes from before, while and after the use of a product. We present a tool that allows you to evaluate the user experience of a product with little effort. Furthermore the tool is available in different languages and we are using the new Spanish Version. We show how this tool can be used for a continuous user experience assessment.
