This was part of a one-day workshop, HexHacks’19, hosted by Hexagon UX and General Assembly. Ninety-one UX designers formed 19 teams to advance the day’s mission: Promoting Underrepresented Communities In Tech.


Research: User interviews
Design: low-fidelity paper prototyping + high-fidelity Sketch prototype
Testing: user testing + stakeholder feedback

Brainstorming about children safety


User interviews were the obvious next step but we could not begin interviews without creating a research guide with clear goals and questions.

“Awesome idea…would be very useful on playground…”

“…can’t use iPhone during class, good alternative…would pay $50”

“I have to send kids home in person, but that is time-consuming.”

Finding solutions to solve problems


We used the whiteboard walls to speed things along and the user insights we uncovered were written on post-its and stuck to the wall. We used classicaffinity mapping to look for any groupings and patterns

How can we make remote tracking device both reliable and affordable?

Final Thoughts

Reflecting on this project, the most valuable aspect for me was our team’s collaboration. Working under the constraints of just a few hours on a complex topic shed light on our own accessibility issue, which enabled us to communicate deeper and better. We pivoted a few times as questions led to more questions, but did so in sync.
