1 Design

The most important design principals that guided TravelTech's final design are: user control/freedom, consistency, learnability, and feedback.

Calendar

Many users were confused about selecting a start date and an end date on the same calendar. To adapt to user demand, we decided to use two calendars, one labeled "start date" and one labeled "end date" in order to reduce user confusion. Other important design decisions in the calendar include linking selection events on the calendar to direct feedback on the map and the chart.

The calendar also grays out older dates in the "end date" calendar after a start date is selected.
