Image Description for the Co-design Session #3 Prototype Discussion Whiteboard

Whiteboard of notes on the discussion of the 5 prototypes. Each group described their prototype, presented their initial process, and discussed the critiques they received.

A Team group

  • Smarties box & plasticine → changes in level through multimodal cues
  • Domes → rough plating on current streets
  • Heating, lighting, colour
  • Holes in domes, depression on ground (hollow)
  • Indicates central groove
  • Tactile plate → ice cream sandwich


  • Warning plate → warn people that a ramp/drop is approaching
  • Constructed like an ice cream sandwich
    • Cane users can hear that they’re on it
  • Haptic features → circuitry inside and underneath
  • Heating plate
  • How many lights? → solicit user feedback
  • Will heating interfere with other circuitry
  • Navigate to plate → meant to indicate upcoming slope → plate at top of slope → find feel with tactility of bumps
    • Metal because of durability and conductivity


  • Too much happening at once
  • Might cause issues for people with cognitive problems/mental health…etc
  • Tactile bumps for people who have difficulty lifting legs may be a problem
  • Constant illumination may be over stimulating → change to gentle illumination
  • No vibration → tactile cues enough
  • Groove maintained to guide canes
  • Keep bumps only at edges for smoother movement for all
  • Holes for heating/drainage/light → hole are very small
  • Hollow space changes sound regardless how you navigate
  • Bumps are like current tactile bumps but smoothed out a little for smoother movement for all

Cats and Dogs group

  • Wayfinding to get to building
  • Little bot to navigate inside building
  • Input your needs (wheelchair, visual…etc)
  • Can pre-program on phone and tap robot
  • Can sign (ASL) to it and use voice control
  • Folds down at the end of day
  • Vending machine for bot
  • Bot can wait for you or it has a recall button to come back when you’re ready
  • Like R2D2, stays within 3 ft of body


  • Could carry parsels? → no because small
  • Can be costly → will be cheaper when scaled up/mass produced
  • People can trip or fall on it if it’s so small
  • Has auditory output
  • Doesn’t require personal info → just preferences
  • Stored on site → connected to larger system (about 3 ft tall to prevent tripping and easier use)
  • Battery powered
  • Has emergency mode and leads to nearest exit
  • How not to freak out pets → if it becomes common you can train it to become used to it
  • Automation eventually leads to savings
  • It’s like google maps but inside buildings
  • Feedback and monitoring system for maintenance
  • 3 laws of robots

Challenging Hedgehog group

  • App to help switch between modes of transportation
  • Real time data
  • Add preferences for things to avoid
  • Open source real time data
  • Personal profile that you can access at bus stop if your phone dies/you don’t have a phone
  • 1st screen → location and destination → mode of transport
  • Give other info → interests, hobbies, good snow removal, construction (detailed information), fallen trees, links to things (311911)
  • “In-Struct”


  • People who don’t have access to tech ($$/learning disability…) include links for 311
  • If phone dies → charging stations which has all the ports
  • Multimodal notifications → multilingual
  • Problems with wifi and data costs money
  • Keep simple and easy to use
    • Focus on GPS aspect
    • Curb cuts and construction
  • Kiosk → find info and charge device

Group#2 group

  • Cross street from streetcar to get to elevator
  • App that works with navigation
  • Safe passage
  • Button activate light system
  • Braille floor and beacons to get to elevator
  • Can use app to interact
  • Announcement to be mindful
  • Seated areas on platform
  • Raised platform (ramps all around)


  • No physical barriers → was intentional, trying not to exclude people, system meant to draw attention to be wary of people crossing, should be pedestrians only
  • What happens when elevator is broken
    • Info will be in embedded app
  • How to scale? → network of paths?
  • What about snow? → robots or heated

Assorted Barrier Busters group

  • Interview next day
  • Access app for accessibility in and out of buildings
  • Voice activation
  • Set up for automation at thresholds
  • External → satellite vehicle comes out to greet and welcome you
  • Helps bring person in
  • Elevator is accessible
    • Spacious
    • Control panels on the side (not on door side)
    • Height accessible buttons
    • Buttons raised and have braille
  • Display outside elevator to tell which one is coming and how long
    • Beeps a few seconds before it arrives


  • Deaf people → visual display screens
  • Smartphone/app → fob with 3 buttons and the ability to pre-set custom preferences
  • New system → learning curve? Building costs?
  • Employer gives people phones
  • Like the idea of buttons on side instead of on door
