Hi,
The situation that I have, its a multi object model with a details panel (3D Cube with Text as child) above it. I would like to have a details panel appear whenever its object is clicked on. If another object is selected the current active details panel will disappear and the new objects detail panel will appear in its place.
Any suggestion about the best way to approach this or code required that I could reference?
Thanks!!

How to initialize object in room with specified positions?
Hello HoloMasters,
How can I achieve something like in this video:
https://youtube.com/watch?v=QrEIIqs2o2E
My Questions:
How to generate a big plane wall like in the video? Does the wall actually hold the objects (couch, refrigerator, etc)?
Which features of SpatialUnderstanding.cs should I use to find big wall and generate the plane base on it?
Is there any easier way to specify object placement. For example, I want to place table right in space between wall and floor (90 degrees). I still confused which approach should I use because right now all 3 major features in SpatialUnderstanding.cs is really confusing. I have tried to use Object Placement features but can't find the place that I wanted.
Thanks in advance for those for can help me.

Holograms are not stationary even in the absence of tagalong script
Reposting this because I checked and tagalong & billboarding scripts are not attached , but still facing this issue.
When I create a single game object in unity, it stays stationary and allows me to walk around and inspect it from all around. But, when I am adding more than such game object and a plane to sort of 'rest them on', as I walk, the entire scene seems to be keeping equal distance from my view. How can I stick them to one position? Thanks for your help!

Hololens Bluetooth not working
Just purchased the Hololens a few weeks ago. During setup I could not pair the clicker. Once everything was setup I went to the setting area and could not find the "devices bluetooth" icon to pair or use any bluetooth devices on the hololens.
I did a hololens reset as well a full factory reset using with window device recovery tool. Updated all the latest updates.
Still nothing.
Anyone else have this problem?
Thanks!

Building a basic image recognition project with Vuforia
I'm not sure if anyone has had success using Vuforia with the new Unity 2017.2.0 (and the corresponding updated HoloToolkit). I created a basic app with just the image target, AR camera, and HoloLens camera. There doesn't seem to be a setting in the Vuforia options to use the HoloLens camera as an anchor anymore, so I'm not sure if that changes anything. But when I build, I get errors despite the different settings I changed. Has anyone figured out how to have HoloLens/or any other AR devices working with Vuforia and the new Unity version? Or any recent Unity version? Super frustrated with this simple task. Thanks!

PhotoCapture.CreateAsync() never executed
Hi,
I'm using the HoloLens and Unity and I try to take a photo.
I have the same problem as in this discussion
https://forums.hololens.com/discussion/897/locatable-camera-known-issue-photocapture-createasync-doesnt-start
This code in a MonoBehaviour in Unity :

Print this output :

Hand Draggable script doesnt work anymore
I used to code with hand draggable on unity 5.5, but when I changed to 2017, it doesn't respond anymore.
When I simulate with the mouse i do get the desired response, but with the holographic emulator, or the hololens, it wont move.
Looking into the code I noticed it has something to do with the:
if (!eventData.InputSource.SupportsInputInfo(eventData.SourceId, SupportedInputInfo.Position))
{
// The input source must provide positional data for this script to be usable
return;
}
on the script, where the eventData.SourceId, forces the OnInputDown to return and not implement the dragging, does anyone know how to implement hand dragging on 2017?

MediaFrameReference Properties
Hi everyone,
I am currently experimenting with the Windows.Media.Capture API and I was browsing through the meta data of my MediaFrames, because I was searching for the Camera's Projection Matrix.
Therefore I printed all the GUIDs of the properties provided by the MediaFrameReference Object (https://docs.microsoft.com/en-us/uwp/api/windows.media.capture.frames.mediaframereference ; MediaFrameReference::Properties) and I found what is was searching.
However there were a lot more properties then I expected and I was wondering where do I find the according GUIDs?
Best regards
Dennis B.

Regarding Microsoft HoloLens: Course 101E-Ch.2-Gaze Input
Hi
The goal of this course https://developer.microsoft.com/en-us/windows/mixed-reality/holograms_101e was to put a cursor on the screen and make the cursor hugging on the surface of a virtual object.
The steps I have done were:
About animation
1. put an animation on the scene of Unity
2. build a project of VS
3. make sure the animation can be deployed to Emulator and work.
About cursor
1. put an object(.obj) which look like a ring, and it was regarded as a cursor
2. also make sure it can be deployed to Emulator, even it was static in the beginning.
3. write the WorldCursor.cs for the cursor in the C# Project that was previously build for the animation.
4. build settings again in the Unity
5. go to VS and run the Emulator
There were two situations that cannot overcome:
1. in the unity, as far as I press PLAY button, the cursor disappear.
2. in the Emulator, the cursor also disappeared while the animation still dynamically shown.
anyone can comprehend my question and do me a favor?
thanks for your reading.

Mixed Reality Immersive headset MR Video player like 360 degrees YouTube video
For all UK Windows Mixed Reality Headset, tested on HP Windows Mixed Reality Immersive Headset. Power Media Player MR UK Store, there is a free to use date time version which is really good for YouTube Star Wars Last Jedi trailer in Immersive view.
The FOV is 95% unlike the HoloLens so you can see everything, look over your shoulder 
You DO NOT need a high power graphics card, see below, for this to run, this should run on 2015 machine which is my Custom PC.
The trailer for Star Wars Battle Zone is intense, as really good pilots you are just sitting in the co-pilots seat 
.
The YouTube trailers to look for are labelled 360 degree.
The Power Media Player MR US Store by Cyber link has free version to upgrade
Graphics Card Minimum
Integrated Intel® HD Graphics 620 (or greater); Windows Display Driver Model (WDDM) 2.2
NVidia GTX 750TB (or greater) DX12-capable discrete
GPU AMD RX 460 (or greater) DX12-capable discrete GPU GPU must be hosted in a PCIe 3.0 x4+ Link slot; Windows Display Driver Model (WDDM) 2.2
Does not need or use Steam VR, just one of the Mixed Reality headset and wearing the MR headset select the free version.
If you save this post to the favourite Toolbar on Edge you can start the Desktop app and the open Edge to select the linked page above to install on you MR PC from the Store then Launch directly

Is it possible to store positions in a database?
Hi,
I am new to Hololens and Unity development. Is it possible to store positions for unity objects (e.g. a cube) in a database (e.g. mysql)? I want to manage these positions in a database and assign additional information to objects. Positions in the real world for unity objects are saved with WorldAnchors if I understood correctly. But a WorldAnchor does not have a position like x, y, z coordinates.
All in all I am very confused how to archive this, or if it's even possible in general.
Kind regards!
