CCC blind accessibility

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
 
  • 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)
  • 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?
  • 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")
  • 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?
