Solving problems with prototypes #1 - Calendar

Often we need to create simple mid-fidelity prototypes to solve problems and test usability.
I think I will share more shots like this, that focus on functionality.

THE PROBLEM
Users must be able to:
• Select multiple date ranges as well as single dates.
• Date ranges must be able to overlap with each other
• View all dates previously selected

CONCERNS
• Too many dates could create a messy calendar
• Once a date has been selected it there must be a way to select it again.

THE SOLUTION
• Greyed out next button ensures at least one date/date-range has been entered before moving on.
• Dates/date-ranges selected must be confirmed with the “Enter” button, once at least one date/date-range has been entered the user can choose to add another or move on to the next screen.
• Each dates/date-range entered is cleared from the calendar and will appear as a tag at the bottom of the screen.
• Tapping a date/ date range at the bottom of the screen will delete it.
