Re: Vive Focus - Getting Started Guide

Hi,

please, do you have more technical guide? Something like, description of the sensor, boundary angles for tracking.....

I noticed that the ceiling was not tracking (when look up).

Thanks

Re: Vive Focus - Getting Started Guide

Hi Michal,

 

If there's insufficient level of detail like a blank wall (or low lighting) then you may come across some tracking issues but technically there isn't any limitation based on angles, so looking at ceiling or floor should work. If you're referring to the chaperone grid system to protect the user, it's currently 2m x 2m and you are centered inside it whenever placing the hmd on (using a proximity sensor).  The inside-out tracking is accomplished solely by the two cameras (and why lighting is important).

Re: Vive Focus - User Guide

So, simple question, and I can't believe I'm asking it. How do you uninstall an application that you've installed?  Also is there a way to force-quit an application that is running? Surprised this isn't more intuitive generally.

 

Follow up question might be when is v 2.0 coming out for developers and if it addresses some of these issues?

We have some big demos coming up with the prototype and these little things are really bugging us. Thanks for your help!

Another general question for the audience - anyone have a hard case recommendation for travel? https://amzn.to/2l8nOTl has a few examples of the same product - curious if anyone has picked one up, or has alternatives.

Hi,

I got one of these:-

https://rover.ebay.com/rover/0/0/0?mpre=https%3A%2F%2Fwww.ebay.co.uk%2Fulk%2Fitm%2F152971235903

Very good and fits the Focus very well. I think it is actually the same as the top item from your Amazon link.

Re: Vive Focus - User Guide

uninstall using
adb uninstall
in the command line interface. If you're not familiar with adb, it is really worth learning more about it if you are working with Android systems such as the Focus.

 

You can quit any app running on the Focus by pressing the Home button.

Re: Vive Focus - User Guide

right, I know there is an adb path to uninstall, but from within VR there doesn't seem to be a way to manage the content you've installed or purchased. Very odd since there isn't a companion app available yet for the phone, and all of the onboarding was done through VR, so It seems everything should be managed through the in-vr version of viveport. 

 

On the home button side of things I have exited the app we are developing with the UE4 WaveVR plugin, but it looks like it doesn't really exit, since launching it again sets us back to where we last were, rather than the beginning. perhaps I need an event listener from when the user goes home to force quite the application?

Re: Vive Focus - User Guide

As with most Android devices you can go to settings->apps to stop or uninstall apps
The Home button will cause the onPause - on Resume lifecycle of the Android app. It's up to the app developer to decide how to handle these lifecycle events, i.e whether to resume or restart the activity and manage resources accordingly

The user manual is here:

Re: Vive Focus - User Guide

Awesome, thanks for the detailed response Dario.

 

Specially on the specifics around the onPause onResume lifecycle, that makes sense and it is helpful. Though I didn't see it documented in the user manual, I do see it mentioned under the proximity sensor piece of the WaveSDK. I'll look further into how this process fits with the Unreal implementations. 

 

On the Uninstall - I was able to do what I needed to from within VR - by going to Settings then more settings then clicking through the 2D android interface the find the Apps menu, then scrolling around through several system apps to find the ones I had downloaded from the Viveport store and remove them. Seems to be a pretty clunky pattern in my view, I'd hope a future update allows us to manage an app from within the viveport interface. I know these things take time to polish, I'm trying to provide useful feedback.

Re: Vive Focus - User Guide

jf@htxlabs.com You can uninstall in VR in Viveport.

1) Go to Library, and switch Left Tab to Install (original is Purchased)

2)  On Install pages, you can find a trash can icon on your right-down corner.

3)  Select trash can icon, and you will see a "X" icon followed up all apps you installed.

4)  Select "X" then apps will be uninstalled.

Re: Vive Focus - User Guide

Hey yeah, there it is. Finally - thanks to Tony's help - I found the little trashcan icon, which you then select to see which apps you can uninstall, and then click through the apps themselves to uninstall. That's definitely the answer I was looking for, though I gotta imagine there should be a better more intuitive pattern to arrive at this basic feature. Now that I know where it is, its fine, but finding it was not very intuitive. 

Thanks Tony and team, glad its actually in there!

Re: Vive Focus - User Guide

Thank you JustinVive for the guide,

I have a question to ask that I have not found..

Is it possible to use the Trackers with Focus for a full body tracking like in Vive?

Re: Vive Focus - User Guide

Tracker requires both BaseStation and install SteamVR on PC side on current design for Out-side-In tracking data.

Focus adopt In-side-Out technology so for short term, you can't use Vive tracker on Focus since it's different protocol and technology behind tracking.
