The Nonverbal Gap: Toward Affective Computer Vision for Safer and More Equitable Online Dating

TL;DR

This paper advocates for developing affective computer vision tools to improve safety and equity in online dating by addressing nonverbal communication gaps and emphasizing ethical, fairness, and privacy considerations.

Contribution

It proposes a research agenda for affective CV in online dating, emphasizing fairness, consent, and longitudinal analysis, and highlights the need for purpose-built datasets and ethical guidelines.

Findings

Identifies nonverbal cues as critical for safety in online dating.

Proposes a fairness-first research agenda with four capability areas.

Calls for ethical data collection and on-device processing to protect privacy.

Abstract

Online dating has become the dominant way romantic relationships begin, yet current platforms strip the nonverbal cues: gaze, facial expression, body posture, response timing, that humans rely on to signal comfort, disinterest, and consent, creating a communication gap with disproportionate safety consequences for women. We argue that this gap represents both a technical opportunity and a moral responsibility for the computer vision community, which has developed the affective tools, facial action unit detection, gaze estimation, engagement modeling, and multimodal affect recognition, needed to begin addressing it, yet has largely ignored the dating domain as a research context. We propose a fairness-first research agenda organized around four capability areas: real-time discomfort detection, engagement asymmetry modeling between partners, consent-aware interaction design, and longitudinal interaction summarization, each grounded in established CV methodology and motivated by the social psychology of romantic communication. We argue that responsible pursuit of this agenda requires purpose-built datasets collected under dyadic consent protocols, fairness evaluation disaggregated across race, gender identity, neurotype, and cultural background, and architectural commitments to on-device processing that prevent affective data from becoming platform surveillance infrastructure. This vision paper calls on the WICV community, whose members are uniquely positioned to understand both the technical opportunity and the human stakes, to establish online dating safety as a first-class research domain before commercial deployment outpaces ethical deliberation.
