What is Interaction Experience?
Interaction Experience (IX) encompasses all aspects of User Experience (UX), Usability, and Accessibility. IX lives as much in the product as in the user's cognitive space — in the interaction itself.
Measuring IX accurately requires validated, standardised instruments. IX Calculator implements the most prominent questionnaires from the literature, applying their scoring algorithms precisely so you don't have to.
