COGA would like to add the following statement at the end of the Note (after User Need 1) on spatialized augmented reality environment: “In addition it may increase understanding of the environment for a user with a cognitive disability.”

Here is the original request URI https://lists.w3.org/Archives/Public/public-apa-admin/2021Apr/0024.html

Can we have some more info on the benefits in terms of what frames the user need? I can clearly understand why the use of symbols are important, however, I'd need more detail on why timing parameters for navigation cues are needed? Also what is the need around filtering notification by relevance - how do you see that working or do you have examples of good practice that may be applicable in XR that you can share? @CityMouse @lseeman

Adding @rainbreaw so she can track relevant issues

@joshueoconnor I wasn't part of the original conversation and want to be clear that I'm not speaking to what David F and John K had in mind with their original response. Instead, what follows is an elaboration from my understand in the hopes that this helps you move forward. The COGA TF will also be able to help further clarify this on the TF call tomorrow.

REQ 1e: Allow users to select symbols that they are most familiar with.

• For some individuals with cognitive disabilities or differences, long term memory is much stronger than short term memory or the ability to generalize or abstract. Icons and other symbols that have a longer history for an individual (such as the old "floppy disk" image for "save" or a PCS symbol instead of an abstracted icon) can be more helpful for some individuals.
• Generalized symbols that have no real recognizable meaning on their own can be really unhelpful for individuals who might need additional support generalizing or deriving meaning from abstract concepts.

REQ 1f: Allow users to set timing parameters around notification cues for navigation.

• I think the stories linked in [New Requirement] Immersive personalisation #13 will help clarify the needs here further

REQ 1g: Allow users to filter notifications by relevance.

• It can be really overwhelming to look through a long list of content in order to find what one needs, especially for individuals with cognitive disabilities.

Thanks @rainbreaw also v helpful
