What kind of suggestion are you making?
General comments on the overall standard or a section such as things that are missing
What should we change?
Add recommendations for what designers should do to prevent glare and shadows. Include reduce reflections (i.e., on high-gloss surfaces)
What should we change it to?
i. install window treatments to prevent glare from sunlight and reflections, as necessary
j. avoid installation of highly reflective surfaces on floors and walls that will increase glare from light sources.
Why should we change it?
Not only is glare uncomfortable, limiting to vision and disorienting, due to challenges with visual perception, people living with dementia may misinterpret glare, reflections and shadows for objects in the environment.

What should we change?
Add additional recommendations and background for choosing colour patterns
What should we change it to?
- Patterns can cause difficulty with the processing and interpretation of visual information.
- Bold/busy patterns and too many bold colours can also add too much visual stimulation to the environment and be overwhelming to someone who has challenges processing visual information. -Choosing calming colour palettes and low low volume patterns can help to create a calming atmosphere.
-Using contrasting colours can make important functional features in the environment stand out (e.g., a white light switch on a contrasting wall, a dark toilet seat on a white toilet fixture, which contrasts with the wall and floor)
-strong contrast in flooring (e.g., when there is a change from one flooring type to another) can be perceived as a step or a hole by someone with visual perception challenges. Choose one colour/tone for all flooring types and use throughout the same level of your space.
-Avoid flooring with strong contrast and visual patterns, as it may be perceived as objects on the floor, an uneven/moving surface or a change in level.
Why should we change it?
High/competing colour contrast and bold patterns can make an environment more confusing and disoriented to people living with dementia.

5. Remember their purpose, and provide them cues as to where to go, or what action is required next - guiding them one step at a time.
Why should we change it?
People living with dementia often experience changes in short‑term memory, spatial orientation, visual perception, and wayfinding. Because of this, they may lose track of:
Where they are going
Why they are going there
What they are supposed to do next
Clear, well-designed environmental cues can reduce this cognitive load. They serve as external memory supports, anchoring the person, reminding them of their purpose, and guiding them one step at a time.

What should we change?
re: TWSIs - it would be helpful to have more information in Tactile direction indicators, including a warning that they may propose a tripping/falling hazard for people with mobility challenges or people using mobility devices (e.g., canes, walkers, wheelchairs).
What should we change it to?
Include guidelines on size of raised edges, appropriate contrast levels, flush installation, slope of bevelled edges and spacing to reduce falling/tripping hazard.
Why should we change it?
I don't think this information in universally available re: use and selection of TWSIs, but it should be.

General comments on the overall standard or a section such as things that are missing
What should we change?
The opening paragraph of section 11.2 re: decorative objects.
What should we change it to?
It should be recognized that trees, planters and other objects (e.g., public art installations) are not simply decorative - they have an important function in helping to create a distinctive and familiar environment for people who have challenges with orientation and wayfinding, and they can act as a steet-level buffer to sound and visual stimulation for people with sensory processing difficulties.
Why should we change it?
Designers and planners should ensure that any street-level assets such as landscaping or public art are not placed along paths of travel - but they should not remove them altogether, as they do play an important part of wayfinding for some people.

Add a point to "walking surfaces of interior and exterior paths of travel in the built environment shall:"
What should we change it to?
Add:
e. walking surfaces should contrast with walls of buildings, and any objects on the ground to improve depth perception within the environment and increase visibility of obstacles (e.g. furniture, planters, etc.).
Why should we change it?
Colour contrast between the floor and any vertical elements (e.g., walls, furniture, bassicades, etc.) can help people with perceptual difficulties to gauge the distance and make these objects more noticable.

What should we change?
Regarding 11.4.2.3, recommendation c: should make the case more clearly that 90 degree angle to the travel direction clearly indicates one direction of travel across an intersection or along a pathway.
What should we change it to?
Attention indicator surfaces should not cover the entire curb surface, so that the direction of travel is clear to the person needing it.
Why should we change it?
It's not currently clear that attention indicator surfaces not only indicate a hazard/obstacle, but they also indicate to the user which direction they need to travel in as they leave the indicator surface.

Add to this sentence: "Configuration of attention indicators is important to ensure their effectiveness when in use."

Add to the end of the sentence
"...to ensure their effectiveness when in use and to reduce the potential for these indicators to become tripping/falling hazards for people with mobility challenges."
Why should we change it?
Many people with mobility challenges or using a mobility device (cane, walker. wheelchair) can find high-profile or improperly installed attention indicators a safety hazard.

Add more detail on what it means to provide "consise, direct and plain" language.
What should we change it to?
a. be concise and written using direct and plain language. It can be helpful to think of 2-3 key words that convey the message. (e.g., "Do not enter", etc.)
Why should we change it?
Being more explicit about what it means to use concise, direct and plain language for accessibility will help with uptake.
