This paper analyses changes in some items of the User Experience Questionnaire (UEQ) for use in the context of Costa Rican culture. Although a Spanish version of the UEQ was created in 2012, we use a double-translation and reconciliation model for detecting the more appropriate words for Costa Rican culture. These resulted in 7 new items that were...

In order to be able to meaningfully classify the user experience and thus the popularity of products, UX questionnaires such as the UEQ, SUS or UMUX are frequently used in practice to measure the UX. This makes it possible to specifically evaluate the ratings of pragmatic and hedonic UX factors. However, it is conceivable that, in addition to users...

Questionnaires are a popular method to measure User Experience (UX). These UX questionnaires cover different UX aspects with their scales. However, UX includes a huge number of semantically different aspects of a user's interaction with a product. It is therefore practically impossible to cover all these aspects in a single evaluation study. A rese...
