Representative Tasks the GUI

Transition from Lo-Fi to Hi-Fi

• order tab changed to view order due to
  confusion with menu tab
• associating ordered items w/ individuals
  removed since it slowed down the order-taking
  process
• messaging utility now has option to use
  keyboard input in addition to handwriting
  recognition
• messaging utility increased from 1 to 2 frames
  due to space required by pop-up keyboard

• vertical toolbar merged w/ horizontal toolbar

• flat menu improved using eVBs treeview ctrl

Design Process Lessons Learned
Contextual Inquiry Task Analysis

• servers have an average of 5 12 customers at
  once, depending on type of restaurant
• while the entire meal is ordered at once, each
  course must be submitted to the kitchen at
  different times
• ability to take orders quickly is very important

Lo-Fi Prototyping Usability Testing

• difference b/w menu order tabs was
  confusing
• associating ordered items w/ individual
  customers slowed down the ordering process
• must include ability to customize all menu items

Hi-Fi Prototyping

• minor changes to GUI design based on features
  limitations of eVB technology
• eVB is a good thing
