Summary

A Gaussian-mixture model of proxemics improved reported social-navigation metrics without sacrificing task efficiency.

The reward gives a reinforcement-learning navigator a dense cost for entering modeled personal-space fields within its view. Across simulated crowds and densities, it improved social metrics while remaining competitive on navigation; real-world human studies remain future evidence.

Why it matters

A Gaussian-mixture model of proxemics improved reported social-navigation metrics without sacrificing task efficiency.

Limits and context

  • Across simulated crowds and densities, it improved social metrics while remaining competitive on navigation; real-world human studies remain future evidence.

Key claims

  1. A Gaussian-mixture model of proxemics improved reported social-navigation metrics without sacrificing task efficiency.
