6 Menu interface: keyboard accelerators The number of keystrokes are minimized, because we only use the unique first letter of the option name (implicit designator) Case equivalence (doesnt matter if you use lower or upper case) Easy rule for designators: –first letter of the option –ALT for alternating program; CTRL to control the properties of the washing program. Hence: Quick: ALT + Q Cotton: ALT + C Wool: ALT + W Delicate: ALT + D Rinsing: ALT + R Spinning: ALT + S Temperature : CTRL + T (use and ) Pre-wash : CTRL + P Spinrate : CTRL + S (use and ) Economic : CTRL + E Start : ALT + Enter

7 Menu interface: guidelines Logical categories and groups determined programmes and modes Consistency determined that the relative order of groups is maintained Order and frequency of use determined the sequencing of the options within a group Navigational clues are provided with titles and graphic techniques Rapid navigation is possible through hotkeys Separate actions for selection and execution Visual feedback is provided by the activation or highlighting of the selected options There are pull-down menus for options that we consider occasional usage Only the available options are presented once a command is chosen

8 Pros and cons Pros: Menu structure: conventional/logical structure. Navigation: distinctive and descriptive titles, simultaneous display, rapid returning to initial menu. Allows working by recognition instead of recall. Cons: Deep structure. Confusing selection. May be insufficient for expert and high frequent user.
