WAITer: Waiting Assistant Information Technology

The WAITer system operates on pocket pc devices, such as the HP Jornada. It is designed for restaurant servers to increase the efficiency of the processes in the life cycle of an order, which begins when the customer is seated and ends when the bill is processed.

  1. The WAITer system operates on pocket pc devices, such as the HP Jornada. It is designed for restaurant servers to increase the efficiency of the processes in the life cycle of an order, which begins when the customer is seated and ends when the bill is processed. WAITer: Waiting Assistant Information Technology Group 1: Andrei Boutyland, Neetin Gulati, Ha Nguyen, Randy Shoopman

  2. Quick Presentation Overview • Current Problems & Proposed Solutions • Representative Tasks & the GUI • Transition From Lo-Fi to Hi-Fi • Development Technology • 5. Design Process & Lessons Learned

  3. Problems: Solutions: • paper & pen order- taking process is inefficient • bills processed from stationary register • face to face communication w/staff can be challenging • servicing multiple tables can become confusing • wireless order submission & order status updates • bills processed at table or anywhere else • wireless messaging • electronic organization of current customer load, with built-in work-flow * * Representative Tasks Current Problems & Proposed Solutions

  4. quick, color-coded table links table status, menu, order summary, billing user log-out employee homepage (tips, schedule, etc.) wireless messaging help utility Representative Tasks & the GUI

  5. 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 eVB’s treeview ctrl

  6. Negatives Positives • easy to learn & use • quick development time • simple code transfer to HP Jornadas • forms nicely support individual development of features • has enough functionality to implement our GUI • eVB IDE crashes on occasion • graphics limitation • (8-bit bitmaps) • can’t define object classes • can’t dynamically instantiate objects • (I.e. Collection) eVB: Development Technology

  7. 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
