The six axes of the Feel Map A hexagonal radar with six axes — motion, agency, breakaway, sharpness, sound, context — and one example profile plotted as a filled shape. The centre of each axis is the quiet end: linear, release and watch, soft, muted, quiet, desk. The outer edge is rotary, you drive it, firm, crisp, loud, pocket. Motion · 22 — mostly linearAgency · 78 — you drive itBreakaway · 68 — firmSharpness · 84 — crispSound · 40 — on the quiet sideContext · 30 — desk more than pocket Motionlinear → rotary Agencywatch → drive Breakawaysoft → firm Sharpnessmuted → crisp Soundquiet → loud Contextdesk → pocket
Solid: yours — move the sliders. Dashed: how community preferences drift over time, illustrative until the community opens.Centre is the quiet end of each axis; the edge is the loud end.
