Problem Statement

The main problem NYU students face is having to navigate the city alone late at night due to late classes and meetings, and being exposed to risks of theft, assault, and violence. Their current options, such as FaceTiming friends or using NYU shuttles, are not always reliable. Rising Asian hate crimes and NYC's increasing crime rate amplify these safety concerns.

User Interviews

Usability Testing

Five in-person interviews were conducted with participants with late-night classes and study sessions on campus.

Round 1 Findings
  1. Users find saving locations like home and library to be convenient since their routes don’t vary much
  2. Users feel that the process of setting the destination and current location is confusing
  3. Users find a pastel color for a ‘Report’ button to be misleading
Round 2 Findings
  1. An excess of warning signs may overwhelm users
  2. Users wish to see the remaining time and distance while navigating
  3. Many international users favor the metric system over the imperial system

Accessibility Considerations


1

I used clear and intuitive icons to ensure that users could easily understand them

2

Every selected color combination meets accessibility standards and passes WCAG test, ensuring sufficient contrast between foreground and background elements

3

To present information straightforwardly, the app prioritizes clear and concise content to benefit users with cognitive disabilities or reading difficulties



Takeaways


Impact

This app boosts users' confidence and sense of safety when walking alone in the city. Many expressed interest in using it if developed.

One peer shared,
"I’d definitely use this app, as I often feel uneasy walking back to my dorm after witnessing situations I’d rather avoid."

What I Learned

I learned that user-centered design is key. Understanding the needs and concerns of the target users guided every design decision which eventually led to a successful project. 

I also learned that gathering user insights is essential because they can offer new perspectives including both metric and imperial systems for distance, making the app more inclusive.
