When the user clicks on the Games and Entertainment icon on the viewing screen, users would be able to choose to play a game or browse the internet. The games will be group games such as trivia, iSpy, Scrabble, etc. Within the Scenario John get really bored as the girls were talking to each other and asks Joe if he wants to play some trivia since John loves movies. The girls realized that the guys are having too much fun and join them. 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. |

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. |
