Abstract: A medical device controller is provided that avoids unintended user inputs and unwanted medical device operation(s). A controller sends display commands to a graphical user interface (GUI) display to generate a first screen having a swipe field with no moving icons that prompts a user to initiate a designated operation by the medical device. When a valid swipe gesture is inputted, the controller generates a second screen with confirm button that requires a valid user press before the controller undertakes the designated operation, the controller generating and sending a command for the designated operation to the medical device when the controller determines that a valid user press has been inputted to the confirm button. The controller also sends commands to generate a status screen that transitions a rotating progress ring symbol and level indicator in accordance with a selected event to clearly indicate the status of medical device operations.
