However, this optimistic scenario is rarely the case.Busy and unavailable waiters, poorly organized menus, and lack of sufficient information on menu items are familiar and often frustrating situations that many diners have experienced. To ease the dissatisfaction associated with poor restaurant dining, our group has developed WIRM, which stands for Waiter and Interactive Restaurant Menu.WIRM essentially is an interactive menu browser that will supplement existing menus and streamline customer service by replacing most of the waiter’s functions. Alongside pictures and detailed descriptions of each menu item, WIRM also is designed to handle various practical features that will aid the diner directly at the table. Some of these include the ability to retrieve ratings and comments on dishes from previous diners, the convenience to place and cancel ordersat the diner’s own leisure, and the option to call a live waiter at any time.Our ultimate mission with WIRM is to create a comfortable atmosphere centered on dinersatisfaction. Our hope is that with more flexibility and functionality in menu selection and diner assistance, we hope to make the restaurant setting more accommodating to each individual diner’s particular tastes and eating habits, thereby resulting in a more enjoyable and pleasant dining experience.Prototype DescriptionThe WIRM prototype is structured much like an online shopping website. It is navigated exactly like a website, with the user pushing “links” that will lead him to another section or option of the menu. The prototype also changes dynamically – certain portions of the page will change while the other parts remain the same. There are three primary sections of the application: (1) the top, (2) the left column, and (3) the main body. The top (1) of our prototype consists of only two items. The title bar contains the title of the restaurant, and then the button in the upper right corner allows the user to call the waiter directly to their table (1a).The left column also contains two items, but these carry a greater amount of functionality. The upper element is the “Grub Grabber,” (2a) which is a search engine that will search the menu by keyword, with an option for an “Advanced Search.” Choosing either of these two search methods will bring up subsequent information in the main body. The lower element in the left column contains information surrounding the current order (2b). As items are added to the order, they appear dynamically in this element. Two buttons allow the user to eithersend the order to the kitchen, or view the current items in progress.The main body contains the bulk of the information, and occupies most of the screen. The top portion consists of six tabs (3a), which allow the user to navigate the WIRM. By pressing any of these tabs, the information suggested by the tab heading will appear in the main body. Each of the tabs contains a unique part of the menu, with the exception of the “Welcome” tab and the “Payment” tab. Each menu item description (3b) contains the name of the food item, price, description, an image of thedish, and two buttons – the first,“Read Customer Reviews” (3c) allowsthe user to read past diners’ ratings onthe item, and the second “Order” (3d)adds the order to the “Current Order”in the left column. All otherinformation also appears in the mainbody.Figure 1: User InterfaceFigure 2: Paper Prototype with all elementsMethodParticipantsWe chose 3 college students, one female and two males, to participate in our user testing. We decided to test the interface with college students since our target user group includes mainly college students and young professionals. We chose a mixture of males and females, as well as students of different ethnicities to diversify the testing group. The participants also felt comfortable with Internet technology, and thus were familiar with the type of interface WIRM provided. Their level of exposure to the Internet made them ideal candidates to observe since weexpected that technologically savvy people would have an easier time using the interface.EnvironmentWe tested the participants in two different environments. The first participant, was tested in the Student Learning Center on the UC Berkeley campus. This was a tutoring environment with an average – above average level of background noise, much like a diner atmosphere. The user was seated at a table with the paper prototype placed in front of him. The members of the team were also seated around the table so that the user could be observed clearly. The other two participants were tested in an quiet office environment, with no background noise and almost no distractions. Again the users were seated at a table with the prototype placed on the table in frontof them. The team members sat either at the table, or within viewing distance of the users to observe their behavior.TasksThe user was presented with these three following tasks:1) You’ve just arrived at the restaurant, and boy, are you thirsty. Your thirst must be quenched immediately, and with a nice glass of ice-cold lemonade. Using WIRM, order a glass of lemonade.2) It’s a burger kind of day. However, you have a rare combination of allergies to dairy products and cucumbers. At the same time, you have a strange inclination to order “cheeseburgers” even though you can’t consume cheese. Order a cheeseburger with no pickles, no mayonnaise, and no cheese. Also, you absolutely love bacon; so add bacon to your concoction.3) You have forgotten about your companion at the dinner
