Here are some tricks in using the Oudie 3.
Using Oudie with your fingers and gloves
Oudie designed to be used with fingers and gloves rather than the stylus. Touchscreen is resistive, buttons are large which makes it easy to operate without a stylus.
This is similar to mouse left-click in desktop Windows. Press with your finger or nail anywhere on the screen to create a "Tap". This way you can navigate through the menus or tap on the map to get the Goto and Airspace menu for example.
Tap and Hold
Tap and hold is something similar to the mouse right-click in desktop Windows. There are few uses for a pop-up menu in Oudie 3, so Tap and Hold is normally used to perform special tasks on the map. An example is moving the Nav-boxes or accessing the Flight parameters by tapping and holding the Glideslope indicator. Similar use is assigned to tapping and holding the Wind and North indicators.
