Using entropy weight method and quality function deployment to develop emotion-driven dashboard interfaces for NEV.
Article in Scientific reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
New energy vehicles (NEVs) demand dashboard interfaces that not only present critical driving information but also evoke positive user emotions to enhance satisfaction and safety. This study develops a structured framework that integrates the Entropy Weight Method (EWM) and Quality Function Deployment (QFD) to embed emotion-driven requirements into NEV dashboard design. 56 Kansei words were collected through an online survey (n = 300) and prioritized to 15 through experts interviews. An anonymous online questionnaire (n = 101, 98 valid responses) collected adult drivers' emotional perceptions across 15 descriptive adjectives. Exploratory factor analysis distilled these descriptors into four principal dimensions: Pleasant, Technological, Stylish, and Minimalist. Entropy weight calculation quantified the relative importance of each dimension, revealing Pleasantness as the highest-priority factor. The QFD process then translated these weighted emotional dimensions into specific design attributes, including optimal color contrast ratios, iconography style guidelines, typography choices, and interface layout coherence. Prototype dashboards developed according to this schema were evaluated in a pilot study, demonstrating strong congruence between user-prioritized emotions and perceived design quality. This framework offers a replicable, data-driven method for systematically aligning emotional user needs with interface design parameters in NEVs, thereby providing actionable guidance for designers aiming to improve user experience through emotion-driven dashboard development.
