Of the four users (including a faculty member, a graduate student, and two undergraduate student) who tested our second design iteration, three had difficulties understanding our geographic and temporal approach to representing people with similar trip details. There was confusion about whether adjusting the start and end date ranges would change the user’s end dates. In reality, such an adjustment should only act as a filter for people who would also be traveling during a specified range. There was generally no confusion about the geographic dimension. People seemed to comprehend that toggling the miles would display people traveling to destinations within that radius. One user noted that the list that appears after clicking on a circle should allow the user to directly click on the individuals in the list and contact them. This may have privacy issues but would be more useful than simply displaying a list of information.

In addition to our “Results Page”, users did not like the fact that in order to details of a trip, they must start at the beginning and step through the entire process. This makes sense and users should be able to change a date range or a location more easily. One user noted the that the “My Info” button was misleading; the user thought it would lead to a profile rather than a map view displaying all trips.
