title: Fixing object when camera open Unity AR
body: <p>Im trying to create a AR Game in Unity for educational project.<br>
  I want to create something like pokemon go: when the camera open the object will be fixed somewhere on the real world and you will have to search for it with the camera.<br>
  My problem is that ARCore and vuforia groundDetection (I dont want to use targets) are only limited for few types of phone and i tried to use kudan sdk but it didnt work.<br>
  Any one can give me a tool or a tutorial on how to do this? I just need ideas or someone to tell me where to start?
  Thanks in advance.</p>
