My idea is to create a robot, standing on my keyboard, and I can play with it.

I took a photo of my keyboard as the ImageTarget. This the the scene in Unity:

I downloaded the Lean Touch library to make the interaction:

Below are the problems I’ve encountered and my solutions:

1. Image Target Textures not show up

This solution works for me:

In the project panel,

Go to Assets >Editor>QCAR>ImageTargetTextures>(Your DB)

Or : Assets >Editor>Vuforia>ImageTargetTextures>click (Your DB) (update 9/24/2017)

Then in unity inspector on the top right above the open button there will be a settings button. Click on that and then click “reset”.

2.When export to iOS, on this help page, it says:

On your device, go to Settings > General > Device Management > Developer App > [your app name]…

But I can’t find Device Management in my iPhone.

This is the solution: HOW TO INSTALL PROFILE AND DEVICE MANAGEMENT?

Then I finally got this menu show up:
