Abstract
This special issue on usability and the user experience focuses on the application of psychometrics to the development and evaluation of standardized usability and user experience questionnaires. The six articles cover advances in the measurement of perceived usability (assessment of the instruments themselves and their application to measuring the perceived usability of mobile applications), attitude toward the Internet, need fulfillment, and the emotional consequences of interaction. Given the benefits of measurement standardization and the new research presented in this issue, the articles should be of interest to human–computer interaction researchers and practitioners.
