Perception

Overview

Perception grew out of an interest in how people experience relationships differently. Partners take a quiz independently, 32 questions across 8 psychological dimensions (emotional-security, communication, empathic-accuracy, conflict-resolution, intimacy, autonomy, shared-identity, appreciation), then the system scores responses and visualizes gaps between self-image and partner perception. The 3D body map uses React Three Fiber to render 400+ colored particles mapped to body regions, inspired by Nummenmaa et al. (2014) research on bodily maps of emotions. D3.js draws multi-layer radar charts overlaying self, partner, and meta-perception scores. The Fastify backend handles auth (email/password, magic links, Google OAuth), sessions, and partner invites, with Prisma/Postgres storing all quiz data. Built as a 6-package Turborepo (web, server, db, shared, monitor, scaler).
