From the View order screen, the user can select to finalize their meal and pay for it. It will display a dynamic receipt on the left hand side and a tip calculator on the right hand side. It can split the bill and each member can pay but credit card and/or cash. Within the Scenario After everybody has gotten stuffed, Joe clicks on the pay button and decides that he'll pay for everyone's meal since he just won the lottery and tips the waitress 31.415% using the calculator. Usability Analysis Learnability Paying after the meal is very easy to learn. It has two main components, the items on the left and the extra calculations on the right. The two options are also very common, making it simple. Efficiency The new electronic payment process is efficient. Since only cash payments require the waiter/waitress, the overall process is made faster. Safety The only issue with safety with this system is that payments are final and can only be changed if the waiter/waitress is called over. |

The payment tab is where the user will be able to pay for their meal. First, an itemized list of their items along with their prices will be displayed. Next, the split and tip can be calculated based on user input in the fields. Finally, the user can choose which type of payment they would like to use, either credit or cash. Paying by credit would allow the user to simply swipe their card while paying by cash will signal the waiter/waitress to come over. Within the Scenario On this screen, Joe and John want to split their check by couple and can easily do so with the split options. They will also be able to simply calculate the tip based on their input. Joe easily uses his credit card while John chooses to pay by cash. Usability Analysis Learnability The payment tab is great in terms of learnability. First, all options are clearly labeled. Then, there is a list of all items and their prices. Next, the tips and splitting of check can easily be done with the built in feature. Finally, the payment options can easily be selected, providing tutorials if necessary. Efficiency The whole point of this tab is to make the payment process efficient. Since the waiter/waitress interaction is cut down to a minimum, the process is faster. The only drawback is when users pay with cash because then the waiter/waitress will have to come over. Safety The only issue with safety with this order payment tab is that payments are final and can only be changed if the waiter/waitress is called over. |

The entertainment tab is where the user will be able to browse the web or play a social game amongst the people at the table. The main view will be two icons, web and games. The web option will open a browser while the game option will open a tiled view of games available. Within the Scenario The four friends decide to play a social word game called Scrabble while they wait for their food. Usability Analysis Learnability The entertainment tab is great in terms of learnability. It will simply be two icons, web and games. Learnability is not really an issue here. Efficiency Efficiency is not an issue for this tab because it is all outside our design after a user selects either game or web. Safety Safety is not an issue for this tab because they can easily go to the tab they meant to go to instantly. |
