    I will be more interested when it has fast, reliable 6DOF head tracking. Without that, it is impossible to make virtual objects appear stable in the world.

    Also, it looks like it needs an Android phone? iOS support (too) is a must.

    Thanks for your response! Our approach to 6DOF is to make the DreamGlass compatible with external tracking devices. We've had success with the NOLO motion tracking system to achieve 6DOF with the DreamGlass.

    The DreamGlass will work on PC or some Android phones, including the Samsung S8 & S9 series. See specifications on our homepage for a full list of compatible Android phones. We are working on supporting iOS in the future.

    Hello, I just received my Dreamglass headset and I'm currently testing it. It was quite easy to setup and plug in my PC. It seems to be working fine (picture, sound, hand gesture recognition), however I couldn't manage to have head tracking working. I tested the demo "VirtualBiologyDemo" and noticed that nothing was happening when I moved my head, I can only interact with the app on my keyboard. Then I wrote a very simple test program in unity to check the head tracking functionnality but I couldn't get any orientation value or reaction. Is it a known problem ? Is there a solution for it ? Is it related to the fact that the device named "DREAM GLASS HID" that appears in my devices list when I plug the USB wire seems not to have a proper Win10 driver ? Do you have a driver for it ?

    Hi there, it could be an issue with the USB connection, let's figure it out. First make sure the DreamGlass is connected by plugging in the USB cables and open your camera app. Flipping though the cameras do you see a camera feed coming from the DreamGlass?

    Hey tclark! I have the exact same problem as Phi7. The headset works fine on a Lenovo Carbon X1, including headtracking. But I cannot get headtracking working on my other PC. (Win 10 Pro N, 1803). When I plug in the usb I do get picture in the Camera app from both the ir camera (displayed as the 'Pen cam') and the rgb camera. I also wonder if it is about missing drivers?

    Hi there, we solved Phi7's issue and it was due to a bug in converting the position measurements to a European system. This has been fixed in the latest DreamWorld Unity SDK version 3.4. Sometimes a loss of head tracking can also be due to the DreamGlass not getting enough power, make sure both USB ports are plugged in and if you have any other external devices unplug them so you only have the DreamGlass and your computer monitor. If you have multiple USB ports try them also. If you continue to have this issue please write us at contact@dreamworldvision.com.

    Hi - Can I use a Samsung Galaxy S7 phone if I just use your powered USB Type C adapter and then a USB-Type-C-female_To_USB-micro-male adapter to go from your powered adapter to my Galaxy S7? - Thanks

    Hi there,

    Unfortunately the Samsung S7 Galaxy does not have a video output which is why it will not work with the DreamGlass. You will need to use the Samsung Galaxy S8 and above.

    Hi,
    I have a cube and DWCameraRig in unity, How I can get an image of cube in "Game" in which when I see through the goggles it looks correctly (not half of that on the left and the other half on the right)?

    Hi there,

    Are you running a build of your application or trying to display the Unity Editor on the DreamGlass? It will only display properly on the DreamGlass after you compile and run a build.

    Hi,
    I am wondering if anyone has a way to display a Samsung s8 screen on the DreamGlass. I am trying to watch Youtube videos on the DreamGlass from a Samsung s8 and was hoping there was an easier way than to build a whole Unity application with the Youtube API.
    Maybe there is an .apk similar to the ARDesktop application that lets you see your phone screen projected onto the Dream Glass? Let me know, thanks!

    Hi,

    You are in luck, we recently added a Unity application that allows viewing YouTube videos on the DreamGlass for Android. You should have access to a folder with the Unity SDK. Take a look in the Sample Apps > Android > YouTubeAR folder. Install the .apk file and follow the documentation to view YouTube videos on your Samsung S8 phone.

    Hi,
    I wanna show the video captured by the DreamGlass camera and see it inside the glass. But I want to see the maximum possible area around and see in the Dream Glass with the maximum size. I am not sure how to set the ScaleFactor in RGB_CameraTexture.cs, or change the size of plane in order to get the best result. I really appreciate if you can help me.

    Hi,

    The RGB_CameraTexture.cs will automatically scale a plane to the correct aspect ratio, so to fill the full field of view you can play with the distance the plane is to the DWCameraRig. In the attached image I found the best position for the plane to fill the FOV is to parent the plane to the HeadRotation child of the DWCameraRig, and place its local coordinates to position: (0, -0.1, 1.3) rotation: (-90,0,0) scale:(1,1,1).

    You can also make the plane a child of an empty GameObject and scale the parent to whatever you like.

    Hope this helps,

    Ty

    Hi! I have received my Dreamglasses. Resolution is great! I love them!
    The question is I saw a demo of marker-based project (animals with pool and tree), how can I build such app?

    And is it possible to integrate Dreamglasses with Vuforia?

    So do you actually plan to release the source code for accessing the internal dreamglass systems? The SDK appears a bit limited, especially with only allowing a single camera for PC. I have also not been able to get it to work on Linux which I thought would work out of the box. Is there anything I forgot? Will the camera issue be solved in a future update? I guess in order to detect different hand gestures we will have to manually train a tensor flow model and replace the DWCameraRig internals as seen in the DWPluginScript_PC.cs file?

    Also I do get errors that the Android TensorFlow libraries are broken by unity on all versions from 2017.3 to 2019.1.

    Could you state what motion to photon latency have you achieved?

    Hi,
    We ran into problem with Dreamglass on Samsung S9 after android 9.0(pie) update. Before the update all worked fine, but now it seems that app crashes every time after it tries to initialize cameras. If I set active camera from Unity to None, it wont crash. Is this known problem?
    Here are some lines from adb logcat from the time of the crash which indicates problem with the camera setup.

    Hi all, We have decided not to continue our DreamGlass development and will stick with VR so we have a head set and mobile battery pack for the phones available for sale. We are UK located so all import fees will not need to be paid if any one in the UK is interested please PM me or email reenconcad@hotmail.com
