Second Iteration

Changes to Prototype

• Some users wished that the date were displayed somewhere on the interface. We chose to add a date display after "Welcome,_______."
• Because some users mistakenly looked around in "My Carpools" before noticing the "Next Date" tab, we decided to highlight the tab to make it more obvious.
• It was noted that the calendar would be more useful if it weren't limited to a single month. We added the option for the user to browse between months.
• Some users were frustrated with the lack of undo options on both the calendar loading and date swapping interfaces. We added the option to toggle the calendar between expanded and contracted states. We changed the date swapping interface from a pop-up screen to its own tab, so that users would be able to navigate away and return at will.
• Some non-native English speaking testers were confused by the wording on the "My Carpools" tab. We had referred to the user as "You" when assigning pickup dates on the schedule, which could be misconstrued as a person's name in some languages. In this new prototype, we decided to simply refer to the user by their name instead.
• Users had trouble figuring out how to swap dates. We decided to add a separate tab specifically devoted to date swaps so that the function could be more easily accessed.
• Originally, we didn't want to include instructions because, as discussed in class, a good user interface does not require much explanation. However, swapping dates is not a regular function, and all of our testers had trouble with that task. We decided to include more descriptive instructions for the swapping interface, sacrificing efficiency for the sake of learnability.
• Users wanted to be able to view their schedules before agreeing to a swap, so we included an option to allow them to view their full carpooling schedules on the same page, improving efficiency through anticipation.
• Because all three users complained about the wording for the ride tracking interface on the mobile app, we changed "Track Ride" and "Untrack Ride" to "Enable Ride Tracking" and "Disable Ride Tracking," respectively, to make the button labels more intuitive and improve learnability.Blah blah blah
