Interaction Experience (IX) encompasses all aspects of User Experience (UX), Usability and Accessibility. As IX researchers, designers, or enthusiasts, we are interested in measuring those as accurately and validly as possible. IX lives as much in the product as in the user’s cognitive space (= the interaction) and thus a good way to measure it is through subjective questionnaires. This page serves as an index to the multiple standardised IX questionnaires that have been proposed in the literature, it is by no means exhaustive but includes the most prominent and interesting instruments that cover a wide range of IX aspects.
