Introduction to Volume 13, Issue 1

For our November 2017 issue, we start with an invited essay from Bill Gribbons on “Is It Time to Drop the ‘U’ (From UX)?”  In this thoughtful and provocative contribution, he argues for and considers the potential consequences of changing the way we refer to our field—specifically, changing from “User Experience” to “Experience Design.” In […] [Read More]

And yes, I am aware of the upheaval that nearly fractured our community when the shift from usability to user experience was proposed nearly two decades ago.

Predicting Post-Task User Satisfaction With Weibull Analysis of Task Completion Times

Abstract Task completion times have been shown to follow Weibull distributions, with parameters reflecting different aspects of the task solution process (Rummel, 2017). The offset time matches UI operation time, including system response time, on the shortest path taken by users (“click time”). The characteristic time describes the solution rate in the stochastic process of […] [Read More]

SUPR-Qm: A Questionnaire to Measure the Mobile App User Experience

Abstract In this paper, we present the SUPR-Qm, a 16-item instrument that assesses a user’s experience of a mobile application. Rasch analysis was used to assess the psychometric properties of items collected from four independent surveys (N = 1,046) with ratings on 174 unique apps. For the final instrument, estimates of internal consistency reliability were […] [Read More]

For example, the first item is “I think I would like to use this system frequently.” If the system under study is one that would […] [Read More]
