All Hearts

Case study of a hurricane relief app designed during Immersion Studio in the University of Washington’s MHCI+D program

The team

The prompt: Explore the ways of using technology to help people cooperate in acts of community collaboration.

We started by researching examples of computer-supported cooperative work in the wild, from Google Docs to Wikipedia. From there, we began to propose the problem spaces we found interesting and that we believed could be enhanced through community collaboration.

Collective ideation


Formative research

We conducted secondary research by browsing research reports, news articles, and interviews online. In particular, we looked at case studies of Hurricane Sandy and Hurricane Katrina, and the aftermath of those disasters. Social media was also a useful source in that we could see which topics people were discussing and what concerns people had during the after effects of a hurricane. We also did some competitive analysis to see what other tools and resources existed for hurricane relief.

Research insights

  1. External organizations and government relief efforts tend to focus on immediate survival needs, so people often have difficulty finding general daily resources and services.
  2. People naturally share information on social media during natural disasters and are eager to help, but their help is often limited to their network of friends and may not be effective or accessible to those who need it.
  3. Outdated and inaccurate information leads to dangerous, unnecessary, and overall ineffective relief responses.
We narrowed our focus to hurricanes in order to stay within our scope



With our design challenge defined, we jumped right into ideation. Over the course of an hour, we sketched over 30 concepts. Some ideas were not feasible, but it was helpful to discuss why they were good or how they could potentially be adjusted.

1. Supply Share

We want to help people who are in need of supplies during a hurricane — this could be anything from batteries, to plumbing tools, or even housing. Members of the community report on the stock of these supplies at local stores, and offer to donate or lend their personal supplies and resources. In connecting these groups of people and providing the real-time status of what’s offered in their area, we can facilitate the sharing of resources.

2. Trip Planner

This idea is centered around people with limited mobility during hurricanes that need to plan how they can run errands, commute to work, or travel anywhere during this time. Community members share reports on which areas are currently unsafe to travel through and if local services and businesses are experiencing any interruptions. This data will be crowd-verified and then cross-listed with forecasted weather conditions in order to provide people with a recommended route so they can get to their destination safely.

3. Rebuilding Community

People struggling to rebuild their life following a hurricane are connected with their neighbors who are going through the same process. Through an online forum, users can ask for advice and share tips for recovery. In sharing personal experiences and exchanging information, they can foster a collaborative environment to help strengthen their community in the weeks, months, and possibly even years following the disaster.


Following a helpful group critique session, we regrouped as a team and rated each concept (scored 1–5) on three criteria:

  • Exciting: Is the idea novel, challenging, and compelling?
  • Relevant: Are we appropriately addressing the challenge statement we defined for ourselves? Would our target audience find this useful?
  • Achievable: How viable is this approach given our time constraints?


Moving forward with the supply sharing concept, we mapped out the features we wanted to include and how we envisioned the various touch points would interact. We sketched our ideas on paper and demonstrated them to one another, discussing ways we could merge our concepts and improve them.

Paper prototype screens

Paper prototype testing

We tested our paper prototype with four participants by presenting them with a scenario: “Imagine your town has been hit by a hurricane, and you are in need of a flashlight.” We observed how they worked through the flow of our app and noted their reactions.

Some key takeaways from usability testing:

  • Visual cues need more clarity. Some of the iconography we used was confusing and not successfully representative of our ideas.
  • Varying interpretations of “low stock” vs. “high stock”. Not everyone has the same understanding of different levels of stock and this created some uncertainty when reporting live stock conditions at stores.
  • Need for trust between borrowers and lenders. Although disasters are the time to put one’s faith into the hands of others, some participants were skeptical of who they were borrowing from.
We received valuable feedback from Cohort 6 on our prototype and the presentation of our work so far. (There’s our team receiving feedback in the back on the right!)

Our revised concept: All Hearts

A mobile app that allows members of the community to borrow and lend personal supplies and report on the real-time stock of supplies at local stores during hurricane recovery.

Searching for supplies
1. Borrowing an item 2. Requesting supplies 3. Posting offers 4. Tracking lent items
Store stock and verification


- Covering daily needs overlooked by organizations

- Direct, real-time links between needs and supplies

- Feeling connected to your neighbors

- Crowdsourcing the rebuilding of a community


  • Know when to move on. Especially given such time constraints, we learned that we needed to make decisions quickly and discard ideas if they simply weren’t working.
  • Don’t jump to solutions too quickly. This was especially tempting for me, as I tend to fixate on solutions far before we even get to the ideation stage. However, this tends to result in poorly thought-out solutions, and I learned the importance of staying open-minded throughout the ideation process.

Next steps

  • Conduct further user testing. Specifically, we want to test with individuals who were recently affected by a moderate to severe hurricane.
  • Continue building trust between borrowers and lenders. Although we built in some features to build trust, we want to measure how comfortable people feel borrowing and lending items from their neighbors.
  • Consider connectivity issues. Given the timeframe and scope we defined, we moved forward with the assumption that users would have access to the app. In the next iteration of our design, we want to think about how to account for poor connection.
