Contact Tracing
Mobile App

For this sales demo, the team was asked to approach the following challenge. Build a demo experience that assumes a future state where we would have access to all the data coming in from the apps that will be built on top of the Apple and Google APIs. In this immersive experience users will have access to an intelligent system that delivers key insights to aid human decision making. Consider how to best support the contexts of both Public Health Officials and Contacts/Cases personas.

How might we create a data model for this demo that reflects what might be realistic (but is not necessarily bound by them)?

How might we use the network modeling idea to not only show the contact connections to others with the virus but also potentially “forecast” where it might go next?

How might we classify multiple “risk” elements for infections similar to how we’ve classified risk for cyber attacks?

How might we seed the demo with multiple user’s experience (i.e. jumping from “clint” to “dylan” to “bob”) and how might the experience change?

How might we build some configuration for different user personas (public health official vs. a patient)?

How might we support personal privacy and notification settings in a forward and transparent way.

Design sprint

Define challenges and sprint questions

Sketch a solution concept

Vote on a user test flow

Sketch a story board for the prototype


Rapid Prototype

We used Figma and the Material design system to build a realistic prototype of the solutions in our storyboard. This first version was built within a day.

Prototype enhancements

After a round of testing, we incorporated the feedback from our representative users. We also incorporated visual enhancements and expanded the set of user tasks.


Developer handoff and building a functional demo

The team is still finalizing the functional demo which is a Flutter app we can run on mobile devices.
