This is a full description of my final project for the UX Design Immersive Course I took at General Assembly in Boston in 2018. See the full portfolio here.

Right off the bat, my goal was to develop a tool to prevent deaths from opioid overdoses. After defining a problem statement, my audience and my “how might we” statement, I developed surveys and interviewed “recruits”.

I suspect drug users need a way to discreetly and quickly contact someone for help because they feel shame and fear about being discovered and called out.

Problem Statement

How might we make the reaching out for help easier, faster and discreet for the addict?

“How might we…” Statement

From this research, competitive review and affinity mapping, I was able to define a persona (“Tiffany”).


The idea for the tool became clear once I fleshed out a user goal from this research.

Tiffany wants to be able to walk away alive the next time she uses or feels like using drugs.

User goal

The end concept is a phone app that pairs with a wearable device (similar to a FitBit). When the wearable detects a sudden drop of blood pressure on the user (as in a drug overdose), it would activate the app to engage the user. If after a certain time there is no reaction from the user, the app would send an emergency signal to EMT.

As part of the project, I developed user flows for the different scenarios, which led to final prototypes.
