SKETCH · 20 single-device ideas · progressive disclosure · v0.1.0
anysurface.com/sti — your phone, your data, your light
A wall of 20 small ideas for the STI onboarding, in the order Stephen named:
start with your own device, entirely local — photos, then your body as a controller, then more
senses — each turned on only when you choose (progressive disclosure). Only then, opt in to
sensing together. And at the very end, the room maps itself with projector scans. Tiles marked
▶ are live single-device prototypes (real camera / sensors, running
in your browser); the rest are idea tiles the fan is asking about.
🔒 everything on these pages runs on your device — no frame, landmark, or sensor value is uploaded
The ballot — help shape the /sti onboarding
sti-arc · Which beats belong in the teacher onboarding, and in what order? (check any — recombine/reorder in notes)
A local photos first ("your data is local") — tiles 1–2.
B progressive-disclosure consent dial as the spine — tile 3.
C hand / finger control (track · pinch · point) — tiles 4–6.
D face control (smile · blink · mesh) — tiles 7–9.
E body / pose (whole-body · raise-hand) — tiles 10–11.
F other senses (location · sensor tape) — tiles 12–13.
G collective, opt-in, at the end — tiles 18–19.
H the projector-scan reveal as the finale — tile 20.
sti-gesture · Which "turn on the light" gesture(s) should we teach first?
A pinch (thumb + index).
B point (place light at your fingertip).
C smile.
D blink.
E raise a hand (whole-body, room-scale).
sti-x · Anything to add, cut, or reframe for the STI room this week? (notes are vectors — a beat we're missing, a privacy worry, a hardware constraint)
A this arc is right — build the composed /sti onboarding from it.
B too many tiles — pick the 4–5 that carry the hour.
C add a "many phones capture this session" beat (STI hour 2).
D tie each beat back to "your phone is a server you own" (STI hour 1).
