3. 23 November 1999Sticky Technology for Augmented Reality Systems 3 Maintenance Subsystem Scenarios Initialize Perform Inspection Report Discrepancy

4. 23 November 1999Sticky Technology for Augmented Reality Systems 4 Scenario - Report Discrepancy Inspector Joe finds rust spots on the right wing of the airplane during a 14-day periodic rust inspection and reports it. –pushButton() Joe is presented with a screen on which he can enter the sticky information. He presses a ‘Done’ button when he is finished. –enterStickyInfo()

5. 23 November 1999Sticky Technology for Augmented Reality Systems 5 Report Discrepancy (cont) After the sticky information has been entered, a set of crosshairs will be displayed for Joe to identify the location of the sticky. –putSticky() –getStickyPosition() A new sticky will be instantiated and submitted to the database. –submitDocument()
