4.4 Immersive personalisation

[nicolocarpignoli]

REQ 3a, can be extended proposing some sort of 'categorisation' support for the user, in combination with Symbols. Symbols can be related to categories, so the user can create semantic sets of objects. To have categories helps users to remember Symbols semantics. They should also have the possibility to create custom categories in order to have their own categorisation system - other than default ones.

REQ 3b, users may benefit to have an option to enable/disable autoplay of content like video/audio/animations.
Also, they may benefit on having explicit controls on playing/pause of any animation/audio/video happening on screen (or if audio, even not visually presented but just playing).

Useful suggestions @nicolocarpignoli we will discuss both in RQTF, thanks.

I find the idea that some may choose to auto play video content within XR interesting - if you wish to outline the user needs in more detail for both of your ideas - that would be helpful.

About REQ 3a idea it is simply an extension of the 'symbols' proposal on the document. It is better to offer to the user a system where he/she can organise things in a semantic way according to his way of thinking, this will address different mindsets and different ways of organising things (this are all very personal stuff). Think about how people manage their files on PCs, their desktops, folders, and so on. Anyone should have the tools to organise content to find them better and not feel lost.

About REQ 3b idea, two things I can add:

• some users have problems with Web contents that are autoplaying animation/sound/audio. This is for people with cognitive impairments, that will be distracted from content and navigation of it, and also for people with Epilepsy. See: https://abilitynet.org.uk/news-blogs/why-autoplay-accessibility-issue (but you can find more resources about this, this is the first I found).
  So this is why it's important to stop autoplay or - better - make the user able to disable it

• autoplay may be also important, so why I was suggesting to add a settings to switch it on/off. This because, as VR is usually a complex and 3D environment, can make feel lost newcomers, and also sometimes it's hard to find where controls are, or can be frustrating to reach a videoplayer that is somewhere at the top of the 3D scene. For people with physical impairment can be hard and frustrating to just play a video or an audio file. So autoplay will be a relief for them.

Thanks for the comments @nicolocarpignoli firstly regarding personalisation and Symbol sets - we have discussed this in RQTF and the consensus is that support for Personalisation Semantics specs that are coming out the Personalisation Task force would be a great help here to meet these user needs.

We need to iterate/update the XAUR with references to these documents - also there will be a new personalisation spec coming shortly I believe. Thanks for the very useful input!

@nicolocarpignoli Regarding your input on autoplay, we discussed this in RQTF and the consensus was that this is dealt with by WCAG SC 1.4.2 Audio control https://www.w3.org/WAI/WCAG21/Understanding/audio-control.html and that this success criterion is equally applicable in XR.
