Demo 1 — Hall’s Proxemic Zones
Edward Hall divided the space around a person into four concentric bands, each the setting for a different kind of relationship. Move the second figure in and out and read off which zone the spacing falls in. The same physical distance that is unremarkable for a friend is an intrusion for a stranger — the zones describe where each relationship is expected to sit.
Demo 2 — Distance Predictor
Preferred frontal distance is well approximated by a baseline adjusted for who the other is, where the two people are from, and how they approach: D = 130 + Δrelationship + Δculture + Δangle. Choose each factor and watch the prediction move between Hall’s zones. The two extreme settings reproduce the worked example in the text (160 cm and 20 cm).
Demo 3 — The Shape of Personal Space
Personal space is not a circle. Mapped in full, the comfort boundary is anisotropic — elongated toward the front, where a head-on approach carries the most threat, and compressed toward the sides and rear. Vary the approach bearing and watch the preferred distance grow toward the front and shrink behind, which is why people turn a shoulder rather than a chest to a stranger drawing near.
