They need to run with a transparent keyboard (adjustable transparency with a wheel button) that sends keypresses through when it is being pressed (with said wheel button). Click on text field etc. and keyboard inhabits full screen of tablet at say 75% or a transparency based on display image intensity (e.g. if the keyboard is created with white icons, then it is less transparent with a light display image in the background). You can scroll the wheel button to adjust right away or even turn it off immediately if you don't need to type, and then depress this same wheel button as you type onscreen to have the keystrokes register as opposed to other touchscreen gestures.
