  1. Presented by Rolf Goedecke, Airbus Standardization of the Cabin Human Machine Interface 23/01/08 WAEA TC Meeting Burbank

  2. Goals • Standardization of the Cabin Human Machine Interface in order to • increase the user acceptance • increase the acceptance of the authorities • reduce the training effort for airlines • reduce the testing effort for the aircraft manufacturer • reduce the development effort • by • design of consistent screen layouts • definition of consistent work flows • definition of a consistent wording • design of a consistent Look & Feel across different systems ! Focus in a first step on touch screen devices

  3. HMI Examples Airbus Cabin Management System Airbus Digital Cabin Logbook Thales IFE System Panasonic IFE System

  4. Layout • Amongst other • Graphical elements shall be aligned to a grid whichshall be maintained throughout the HMI of the application/device • The screen shall be divided into areas provided for specific purposesE. g.: content area, navigation area, title area Example: title area optional navigation Navigation area

  5. Complexity • Amongst other • Navigation hierarchy (menu structure) shall be of minimal complexity • Number of different graphical elements shall be minimized • Same function shall have the same appearance E. g.: a Button shall always have the same size and appearance clearly discriminable from other graphical elements Example for graphical element diversity: Graphical Element Button Label List Scrollbar Toggle Button Push Button Image Tree view

  6. Design rules • Text and characters • Alignment of text (left/right/center) shall be used consistently all over the HMI • The number of different character sizes and styles shall be kept to a minimum • Upper/lower case shall be used consistently • Only one sans-serif font shall be used • Spacing • Spacing between and within graphical elements (E. g. the text or icon on a Button) shall be appropriately • Colors • The number of colors shall be kept to a minimum • Contrast and saturation shall be used appropriately • Specific colors (E. g. red/green) shall be used according to the policies of the aircraft manufacturer

  7. Wording • Wording shall be used consistently all over the HMI • Aircraft specific terms and abbreviations shall be used according to a standard catalog

  8. Definition of reusable assembled structures • The HMI is mostly composed of reusable assembled structures which shall have a constant layout and Look & Feel throughout the HMI of the application/device • Amongst others these structures are • Scrollable lists of text composed of Buttons, a List, and a Scrollbar (e. g.) • Virtual keyboards and other complex virtual input devices • Dialogs (e. g. the login dialog, message boxes with confirmation Buttons)

  9. AEEC HMI standardization proposal • Feedback is appreciated from users/operators • Send comments, opinions, questions, proposals ect. • to Rolf Goedecke, Airbus (rolf.goedecke@airbus.com) or • to Earl Nicks, AEEC (wen@arinc.com) or participate next CSS meeting
