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
- 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
- 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
- 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?
