The user interface may choose to present the user with any literal characters of the mask visible within the field , to communicate the desired input to the user , and to lower the user 's keying effort by relieving them of the need to key in the static literal portions of the mask . The server process can handle lengthy database transactions asychronously from the user interface , so that the user interface need not pause during these transactions . Note that the User Interface may present the decimal value with a localized decimal point and other picture clause embellishments . It is possible that a particular user interface may ignore this setting . For example , an X-windows based user interface may display the image , while a command line version may write it to a file for later display . New , more effective and user-friendly user interfaces shall be developed , along with efficient methods for the collection of address , time , and distance information where available electronic databases are not adequate . For this reason , any program that does network i / o , or even uses the serial port , should always , always , always use asynchronous i / o , so the user interface wo n't block when these network errors happen . The report stresses the need for research on how Internet voting would affect voter turnout , what interfaces would be best for such systems , and how to test and certify such systems . The application 's user interface may use these commands for operator-initiated intervention as well as for testing .
