CCC blind accessibility People * Sai (@saizai, https://s.ai/ccc/ws) [35c3 talk/workshop on blind navigation, is functionally blind] * Kai (@sistasonDE) [contact for @c3awareness] * Niklas (@nwng) [@c3blind] Projects * Safety (assemblies) * faceplanting * Hazard: not cane detectable (too high) * lowest, nearest edge higher than knee & lower than top of head * e.g. signs, spheres, phone booths, guy lines, branches, underside of stairs * Fix: make it detectable and/or blocked * put something solid under it at floor level to prevent walking into faceplant zone * e.g. backpacks, speakers, large cable cover * Please no backpacks etc. This is a fire safety hazard. * Maybe put special textured tape on floor? [Pixtxa] * yes! or bumps like cable covers - Sai * Exceptions: light, smooth-edged furniture (e.g. tables, chairs) that won't hurt to run into * tripping & shin bruises * Hazard: not cane detectable (too small or movable) * cane might pass over it * e.g. cables smaller than ultra-thick power cables, bollards lower than elbow height, small robots / toddlers, small bags in walking area * Fix: make it detectable, safe/padded, or gone * e.g. cable covers; padding around short bollards; child care services; sound generator on robots; clean up trash; stow bags on tables or along the wall; tactile paving indicator for upcoming hazard (eg stairs up) * falling * Hazard: walking surface drops (ledge or very steep slope) * e.g. stairs down, edge of platform/stage * Fix: hazard warning or barrier * e.g. tactile paving (bumps or horizontal lines); cable covers with prominent texture (like crosshatch); tape with very prominent texture (strands, bumps, etc) * for stairs, mark both start and end * Talks * audio description * 1st done w/ Sai's talk @ 35C3, with some issues: https://s.ai/ccc * Slides (speakers & independent tracks / workshops) * link your slides / docs / etc through Frab * please make slides with light text on dark background * why: the default dark on white means projectors put out more light, which is painful for Sai * Websites * improve accessibility to screenreaders * learn how to use your own screenreader with help from blind people ? * Tactile maps of CCL * What to make * Broad map (of CCL "naked") * Mark (raised lines) * rooms * hallways / paths * texture of floor (smooth vs carpet) * Label (symbol, or Braille name / #) * rooms * toilets * exits * escalators / elevators / stairs * "you are here" (prominent raised / textured feature, eg a meeple or bump dot) * Congress-specific: help desk, CERT, etc * Detailled Map per Hall (as built w/ assemblies) * Get maps for CCL and each hall with rough installations * improve installation-accuracy per day. * How to make * In contact with @c3nav for maps * They have a full 3D-Model, but it's non-optimal for printing (not two-manifold etc) * Simplest useful version (handmade shallow tactile map) * print a top-down outline map * draw over the walls with TactiMark (for raised edges) * textured fill (e.g. zigzag) for rooms, none for halls * Nice non-tech version (handmade physical model) * scale model using crafting supplies, model railroad / wargame minis, etc * Simplest tech version (3d print shallow tactile map) * https://www.dzb.de/en/production-on-demand.html * Nice tech version (3d print a model of Congress) * make 3d image (e.g. using laser rangefinders) * "Extrude" the structure per software * export and modify for 3d-printing * find a hackspace to print them * Where to print? * TODO: Which hack-/makerspace would be up to commissions on day 0/1? * only applies to detailed map; broad map can be made beforehand * Audible landmark indicators * Requirements * distinctive, easily identifiable sound * branded sounds (like Japanese subway stops) * chords - need not be full chord each time it sounds (e.g. wind chimes have different notes per chime; together they function like an arpeggio) * cuts through general crowd noise * Volume check on day 1 (hearable but not loud) * not drive people crazy when heard over and over and over * Rickroll * Cantina Band * It shouldn't sound like toys * At the GPN, there were squeaky chickens for pallet trucks that sounded like children's toys, which is why hardly anyone made room. * Implementations * Physical * wind chimes (e.g. wood, metal) * Electronic * ESP8266 + Power Amplifier + Speaker + Powerbank * poweramp for 3.3V? * https://www.dfrobot.com/product-1121.html * Simple mobile speakers with TF-Card, USB, … * Braillebombing * Things to add: * Braille to any print-only signs * bus stop names (e.g. "this is stop Foo") & available routes ("bus # 123 to Bar") * mini tactile maps to street crossings http://www.apsguide.org/chapter4_tactile.cfm * floor numbers to the inside wall of elevator entrances, chest height * exit name at top & bottom of stairs, on wall-side surface of handrails (where fingers would naturally graze it) * bathroom markers (with gender if applicable) * room numbers / names * raised tactile layer on existing maps, arrows, etc * Maybe also add some braille stickers at sticker table? * Methods * 3d-printed braille signs on-demand * braille labeler with stick-on labels * TactiMark (or similar) * Prep needed * where can signs be usefully added? * what can be distributed among a lot of people? * what's important to designate?
