The nature of the input device determines how much precision or sensitivity you want to set for object selection. For example, when they are using a mouse, users can select objects much more accurately than when they are using their fingers on a touch screen.

You can change the sensitivity for selection through the TLspSelectControllerModel.setSensitivity method. Consult the javadoc of this method for more information.

The touch controller, TLspTouchSelectEditController, is already configured with a sensitivity appropriate for touch screens.
