[=&;;;;;;quot]What is Augmented Reality?[/][=&;;;;;;quot] [/][=&;;quot]Augmented reality technology places virtual content in a live camera view of the real world, thus creating an augmented world where virtual and real world elements appear to coexist. A device, such as a mobile phone, acts as the looking glass through which this this augmented world may be viewed.[/][=&;;;;;;quot] What is a trackable? A trackable, also known as a target, is a key element of vision-based AR.

When we have this error, "Invalid file format.Only 8 bit gray scale or 24 bit RGB of file type JPG or PNG are allowed."

Is this the "Result Code" we should get from the API --> BadImage / Unprocessable Entity (422) / Image corrupted or format not supported (target POST/PUT response)

Thank you!

Hello, please provaid PHP samples where we can use cURL instead of HTTP_Request2. Most of us cant use HTTP_Request2. Thank you.

Is there any way to disable extended tracking so that a AR objects disappear when physical image target is removed from camera's view?

I am testing Vuforia on Hololens and would like the holograms that are displayed based on image targets to be removed from the view if user looks away from the image target of the image target is covered / removed. The hologram should reappear when user looks at the image target again.

Hey All,

I a newbie developer who would like to enter in AR field.

As of now i am familiar with direct usage of Vuforia features as tutorials provide but i am seeking for more in-depth knowledge about vuforia engine i looked up into Vuforia api library and found sooo many classes with which you can play around ..but i don't know how to start. 

Is there any tutorial/source/documentation which would help me to get started with basics of how to use those functions and classes in scripts ? ...

Thank you

Hello.

I am asking for your inputs.

I want to make a dynamic AR app where a user makes one install but I will be able to add new contents and user gets it without downloading a new app version. Only SYNCH and the device gets data from our database.

A database must be of targets and the streaming assets to display.

Can you guide me like the steps to follow, SDKs to use and APIs. I am familiar with Unity.

I am running a script to update the gameobject of a trackable behaviour based on conditional statement by using

myGameObject.transform.parent = myTrackableBehaviour.transform;

But this clones many 'myGameObject' under myTrackableBehaviour but I want only one to be updated every time its being run in void Update(). How can I achieve it?

Hi, I am new to Vuforia and unity and really want to know what is wrong. I want to track the number of targets detected currently and their position, and found this code on the other forum:

Hello all,

I faced with some interesting issue, i hope someone could help me here.

I want to build an app that the users will add images for target tracking to cloud database.

e.g. - user see a specific shirt, he films it and add some 3d text / objects or something, and the cloud database will update.

so another user will film that shirt and the tracker object will appear...

hope i explained myself properly...

thank you!

Hi, I'm a newbie in Unity and Vuforia.

I'm trying to create a mobile AR app to create a virtual piano keyboard on a flat surface and be able to play the keys using my fingers.

I wonder if this is possible using Vuforia and how difficult this would be. Also, I wonder if the detection would be accurate enough.

If this is difficult to do with Vuforia, I would like to know if there's any better alternative solution to achieve this.

Lastly, I wonder if it is possible to show my fingers in front of the piano keyboards and not behind it.
