hmd | Detailed Human Shape Estimation from a Single Image | Computer Vision library

How would one go about mirroring or cloning the WebXR 'immersive-xr' view from a HMD like the VIVE or Oculus in the browser using the same WebGL canvas?

There is much discussion about copying the pixels to a texture2D, then applying that as a render texture, or completely re-drawing the entire scene with an adjusted viewTransform. These work well if you are rendering a different view, such as a remote camera or 3rd person spectator view, however both are a waste of resources if one only wants to mirror the current HMD view on the desktop.

Self answered below as there was no solid answer when I ran into this and I'd like to save future devs the time. (Especially if they're not all to savvy with WebGl2 and WebXR)

Note, that I'm not using any existing frameworks for this project for 'reasons'. It shouldn't change much if you are, you'd just need to perform the steps at the appropriate place in your library's render pipeline.

So i followed googles tutorial for their barcode scanner (this one) and the qr scanning works like a charm. The only problem is that i don't need qr codes but rather bar codes. But they don't work. It doesn't detect anything. I tried multiple online bar codes and ones from around the house but none got recognised as a barcode.

this is the code in my activity that handles the image and scanner:

I cloned the openVR repo and went directly to compile the driver_sample and hellovr_dx12 and hellovr_opengl projects. The builds were successful. But both the helloVR applications failed to launch with an error:

In Firebase, I'm getting various crashes in my production app (uses Dexguard), while using Parcelable.

These crashes are now affecting almost 200 users and are grouped into 3 entries on Firebase.

In one entry, crashes are only on Samsung devices, in another, are only Xiaomi devices and in the other, are more brands but 81% are from HMD Global.

ALL these devices are running Android 10 so this might be a problem with this OS version. I can see that the crashes are contained to 5 or 6 custom objects. Other than that, some crashes are related to:

Would like to experiment with fading the display towards black as the pixels get further from the seat spot of the HMD; My natural instinct is for my eyes to track anything that appears to be viewable in the field of view meaning I inevitably look away from the seat spot and spoil the illusion - was thinking if the image faded away then it would be more natural to keep within the sweat spot...

Does WMR provide any way to modify rendered frames before they are output to the displays?

I am a new learner of python and i am trying to scrap the name and price of particular hotel form goibibo. But every time it shows the output "None". I am not able to figure it out.

Odd question, but I'm having trouble boiling it down to a coherent question.

I have sampled data (60Hz) from Brekel OpenVR recorder, which includes the following parameters for the HMD itself:

• X, Y, Z positional coordinates
• Euler angles rotX, rotY, rot.

I'm processing the data in python. Overall, what I'm trying to do is to calculate measures of mobility: did someone look around more or less during a segment, and did they move around more or less?

For the positional coordinates that wasn't too difficult, I was able to calculate displacement, velocity, etc., by using the distances between subsequent positions. Now for the Euler angles, I'm having more trouble.

I've searched for the answer to my question, but none of the answer seemed to 'click'. What I think I need, is to convert the Euler angles to a directional vector, and then calculate the angle between the directional vectors of subsequent samples to see how much the gaze direction shifted. Once I have those, I can calculate means and SDs per subject, to see which of them looked around more (that's the idea anyway). I am unclear on the mathematics though. It would have been easier if my coordinates were roll, pitch, yaw, but I'm struggling with the Euler angles.

Suppose the Euler angles for two subsequent samples are:

• (rotX, rotY, rot) = (20°, 25°, 50°)
• (rotX2, rotY2, rot2) = (30°, 35°, 60°)

How can I quantify with what angle the direction of the HMD changed between those two samples?

I try to find the name of a country through the name of a city. pycountry did the work for me!

I'm building a 360 panorama viewer with A-Frame 1.0.4 and I'm having some trouble with older devices that I don't know how to solve. I'm testing in a WebView inside an Android application.

On most recent devices, the gyroscope and accelerometer work great, but on older devices (for example ASUS X008D), it's all shaky, the view can't stay still when I put the phone on the table or when I hold it. I thought it could be due to polyfills but I can't figure how. I added some logs to check for DeviceMotionEvent and DeviceOrientationEvent and both are recognized but it seems like it's not enough.

How could I be sure that the events are handled correctly and eventually disable the hmd in look-controls manually when it's not stable enough? There would still be the dragging and I would be fine with that.

Thanks for your help :)
