State of Mind has one gesture on a continuous axis. A headset has no bezel to slide along — so the axis becomes the one the medium already has. Unpleasant is near. Pleasant is far.
APPLE VISION PRO · 2023 · OUTLINE TRACED FROM THE INDUSTRIAL DESIGN
On a wrist there is a slider because there is a bezel to slide along. In a headset there is no bezel, and floating the slider in front of you turns a one-second gesture into aiming at a menu. So the axis becomes the one axis the medium already has.
Unpleasant is near. Pleasant is far. Where the form ends up is the entry.
The form holds eight degrees of visual angle wherever it sits, so scale carries nothing. Depth is read from shadow weight, contrast, saturation, focus, and occlusion against the panel — which is pinned at one meter and never moves.
It leans on vergence, on occlusion, and on a display that can hold a convincing near plane. A passthrough headset has all three. A pair of glasses may have none — narrow field of view, a display that can only add light, and in some form factors one eye rather than two.
| CUE | HEADSET | GLASSES |
|---|---|---|
| Vergence / true depth | Primary | Unavailable or weak |
| Occlusion against the panel | Primary | Unavailable — additive display cannot subtract |
| Shadow weight | Supporting | Becomes primary |
| Contrast and saturation falloff | Supporting | Becomes primary |
| Size in view | Held constant | Released — size carries the axis |
The axis is invariant. The encoding is negotiable per display.
