This is Renault Twizy's AR (Augmented Reality) software.
If you select a vehicle color on the setup screen, you can place a twizy of the selected color on the screen and take a picture.
When operating Twizy, the grid will be displayed when the device recognizes the horizontal plane, so tap anywhere on the grid to place Twizy. You can also move and zoom in.
You can also drive a virtual Twizy by manipulating the on-screen handles.
