Data for: EpiRate – Development and usability evaluation of a web-based verified feedback system for assistive technologies in epilepsy

This is the online supplement for an evaluation study of EpiRate - a web-based verified feedback system for assistive technologies in epilepsy. At present, patients, caregivers, and doctors lack information to choose the most effective assistive technologies (ATs) for people with chronic conditions. This is also true for epilepsy where studies have shown that lack of information about these tools is a major barrier to wider adoption. To address this need EpiRate, a feedback system for ATs for people with epilepsy was developed and evaluated. In the development phase, qualitative methods were used to determine user requirements and iteratively improve prototypes of the feedback system. In the evaluation phase, a quantitative usability study with 146 participants was conducted. Usability was assessed using established questionnaires measuring first impression, perceived usability (PWU-G), and visual aesthetics (VisAWI-S), and results were compared across devices (smartphone, laptop/desktop, tablet). The summative evaluation showed good usability across all measures (PWU-G: M=5.40; VisAWI-S: M=5.37; First impression: M=5.32, all on a 7-point scale), with an average task completion time of approximately two minutes. Usability ratings were consistently positive across devices, with only minor differences between smartphone, laptop and tablet users. The four-category rating structure (usability, functionality, reliability and overall impression) was rated as ideal by 86% of participants. EpiRate is an easy-to-use, cross-device web platform for collecting verified AT feedback from people with epilepsy. This online supplement includes - Raw data: The raw data contains only the responses of persons who were included in the analysis. - Analysis script: An R-script to replicate the analysis reported in the manuscript.
