Reconsider AR and VR buttons

[dmarcos]

We're entering the mixed reality era and we might have to revisit again the buttons. VR and AR might not make sense anymore. I was thinking about replacing them with an XR button but not sure yet. It seems giving a choice to the user to enter VR or AR modes is making less and less sense.

We ultimately still have to decide whether to launch an immersive-vr or immersive-ar session. Perhaps adding another field to the webxr system like sessionType, with a default to immersive-vr? Since if you're doing MR stuff you're already going to be in there requesting additional features, so explicitly specifying immersive-ar as well doesn't feel like too much extra hassle.

Having said all that, there are likely still going to be cases where developers would like to offer varying VR/AR experiences, in which case they would still want the option of two separate buttons.

Happy to help with any new assets we may need for the button/s, @dmarcos.

I saw a recent discussion suggesting a pattern where apps should use AR or VR mode depending on whether the user was in passthrough or VR immediately prior.

This info is available to a webXR app (though I'd need to check back to discover exactly how).

This feels like a good default option.

On the other hand, some apps may only make sense in AR or VR, so for those cases it's still desirable to be able to force into that mode, regardless of the mode the user was in previously.

@thedart76 awesome to here from you. If you have still the original files of the buttons around. it looks we will need one [XR] button with same style as the current ones. Thanks so much!

@diarmidmackenzie I was planning to leave current AR and VR buttons around but default to an XR one. Devs can opt-in to VR, AR or both as of now. Does it sound sensible?

[diarmidmackenzie]

So does pressing the XR button take the user into either AR or VR, depending on whether the user was in passthrough mode prior to pressing the button?

Not sure a page has a way to know what was the previous state. The XR button would just enter immersive mode and developer decides if it's going to be immersive-vr or immersive-ar. The user no longer has a choice by default

@dmarcos, sure, I'm sharing two versions of the new XR button, using either style (opaque or transparent).

In the screenshots below, I edited the SVG path details directly in the Inspector to preview how they would render.

Downloadable SVG assets here:

• aframe-xr-button-opaque
• aframe-xr-button-transparent

You can count on me for any tweaking or iteration we may need/want to do.

I vote for this approach as it would ensure good UX for either type of immersive app.

My understanding is that it does have access to this info. I read a discussion about this somewhere - will try and dig out a reference.

For experiences that support both modes, this would be a nice function to have.

@thedart76 thanks so much. you rock!

I made an attempt at this. Let me know what you think

@dmarcos, solid UX flow!

I'd like to do a final readability test of both buttons in the headset (Quest 3) to validate or tweak the letter spacing, due to the different backgrounds (solid/transparent), color contrast, and font weight.

LMK when and where I can give it a try (feel free to DM on other platforms too).

PS: I might get back to you with some delay these days as I'm in Vienna for the AWE2023 :)

@thedart76 you can already try with master builds. See links in commits https://github.com/aframevr/aframe/commits/master

One piece of good criticism. Is that when we show one button we should still display [VR] or [AR] vs [XR] that is a less common known of a term.
