  1. GUI Design for GEM Lite on a Pocket PCGeneral Dynamics C4 Systems Evan Desmarais Gregory Kern

  2. Introduction • General Encryption Manager (GEM) • GEM Lite • Stage Two • Last Year Simple Networking Protocol

  3. Background • Dell Axim X5 Pocket PC • 400MHz Intel XScale™ processor • 64MB RAM and 48MB ROM • 3.5 inches thin film transistor (TFT) screen • 240x320 pixels in 16-bit color • How does current GUI research apply to PDA?

  4. Project Scope • GEM Lite connects to encryptors • About 50% of the GUI depends on these connections • Lab tour

  5. GEM Lite Pocket Main Shell • System status indicator • Device count indicator • Button cluster • Startup • Shutdown • Discover • Devices • Events • Requests in Progress • Menu/Icon Navigation Bar • Scrollbar

  6. GEM Classes GEM_Date_Time GEM_Default_Settings GEM_Help

  7. GEM_ChecklistPanel Class Alternating soft colors make options more readable GEM_ChecklistPanel object used to display the Event Log Settings portion of GEM Lite

  8. GEM_DataGrid and GEM_Record Classes GEM_Record object uses alternating soft colors to make data more readable with minimal distraction GEM_DataGrid object shown here as a component of GEM_GridPanel class Each row is selectable GEM_Record example GEM_DataGrid example

  9. GEM_Alert Class Descriptive event messages Windows form covers all other panels, forcing user to acknowledge event before being allowed to continue

  10. GEM_BarGridPanel Class Reusable panel class displays static routing tables and network manager from GEM Lite. Icon Bar: Images aid the user in determining each button’s function Each cell selectable and can be edited separately using buttons from the icon bar

  11. “Unique” Panel Classes GEM_BGLPanel GEM_AuditDataPanel covers two different views

  12. Confirmation Panels

  13. Error Checking and Prevention • Regular Expressions • Disabling Options • Save Options • Deletion protection

  14. Aesthetics & Accessibility • Button placement & icon design consistent with well-known applications • Color scheme tested under colorblindness simulation • GUI designed to give useful feedback regarding user actions

  15. Aesthetics & Accessibility (colorblindness testing) Original Protanope Deuteranope Tritanope

  16. Testing • Development testing (finding/fixing bugs) • Exploratory testing • Task-based user test

  17. Conclusion • Proof of Concept • Functional • Aesthetic • Accessible

  18. Recommendations & Future Work • Build back-end functionality • Design & build encryptor-dependent portions of GUI • Database solution • Landscape mode • Screen magnifier
