There are two ways to interact with your geometry in Arkio. You can edit or move shapes from a distance using the laser, or grab shapes or their features directly with the black interaction point in front of the controller. The default tools selected on your controllers when you start are the create (right) and edit (left) tools.
You can grab shapes no matter the current tool activated on your hand. This greatly simplifies the modeling and makes it very accessible to move, rotate and adjust anything within reach.
To edit shapes you can select the edit tool from the main menu, or simply reach into shapes with the controller and pull the trigger to move, or stretch shapes, faces, edges and vertices using your hands.
