Proxemics Design
Spatial proximity changes everything. An element at 30cm doesn't carry the same emotional weight as one at 2 meters.
What is it?
Proxemics Design applies Edward Hall's anthropological framework (The Hidden Dimension, 1966) to spatial interface design. Hall defined four zones: intimate (0-45cm), personal (45cm-1.2m), social (1.2-3.6m), and public (3.6m+). Greenberg, Marquardt et al. (2011, 'Proxemic Interactions' — highly cited paper) formalized how digital interfaces should behave differently in each zone. In AR/VR, this is fundamental: an element at 30cm from the face has intimate emotional weight — it demands attention, creates urgency. An element at 2 meters feels social — informational, ambient, less pressing. The ETL framework and proxemics are directly compatible.
When to use it
When placing UI elements in 3D space. When designing AR interfaces where distance from user varies. When an interface feels 'too aggressive' or 'too distant' — it's likely a proxemics mismatch.
How to do it
Map your UI elements to Hall's zones: what needs to be intimate (close, urgent, personal)? What should be social (ambient, informational)?
Define behavior transitions: how does a UI element change when the user approaches or retreats? Does it grow, reveal detail, change opacity?
Test with real spatial distances. What feels comfortable at 30cm on a screen may feel invasive at 30cm in a headset.
Create a proxemic behavior spec: for each element, document its behavior at intimate, personal, social, and public distances.
Pro tips
The most common AR mistake: placing everything at 'reading distance' (personal zone). Vary your distances intentionally — ambient info belongs in the social zone.
Cultural context matters enormously. Hall's original research showed that intimate distance varies by culture. Your proxemic spec should be culturally adaptable.
Combine with ETL's Atmosphere First: the emotional atmosphere determines which proxemic zone feels appropriate. A clinical tool keeps things at personal distance. A playful experience can use intimate proximity.
