Hi, I am studying public outdoor spaces in built enviornments which are easy to use, I am focusing on Public toilets. I would love to understand more about this.

1. What is a public outdoor space in the built environment? - Definition
2. Define the key Concepts of Norman (Constraints, affordance, Signifiers/feedback) - referencing required
3. Explain whether public toilets have a good design in relation to the above concepts
4. What are some of the well designed aspects or objects of the space which makes it easy to use it in public outdoor space

I will need references from = The design of everyday things, revised and expanded edition
