AHFE Open AccessTowards an Ergonomic Assessment Framework for Innovative Digital Interfaces: A Multimethod Approach with a Smart-Building Use Case
Abstract
This study proposes a multimethod ergonomic assessment framework for innovative digital interfaces, using a smart-building software ecosystem as a representative use case. Eight participants completed two interactions with each interface (End-User App and Management Software) under controlled conditions. The assessment combined subjective questionnaires, task-performance measures, electrodermal activity, pupil diameter, and face units’ analysis. The results were more favourable for the End-User App, which showed acceptable usability, a more positive user experience, and improvement with repeated use. In contrast, the Management Software presented lower usability, more errors, greater difficulty in complex tasks, and higher cognitive and emotional demands. Overall, the study shows that combining subjective, performance, physiological, and emotional indicators provides a more comprehensive assessment of interaction demands and helps identify usability issues beyond isolated measures. The proposed framework offers a practical basis for the human-centered assessment of innovative digital interfaces.
