Help: Interactivity with Single Marker and a small button

[DejaVu]

1. Does the toolkit supports interactivity using a two markers, One a  normal marker and other is smaller marker which acts like a button.

   When the user closes small marker the rendering 3d object should change.

Similar to this video , but not such complex. I just want to render a new 3D object when the marker is covered. Video is here:
