As a designer for BlueDot Inc. in the summer of 2016, I designed for their upcoming suite of consumer applications focused on international travel, infectious diseases, and diagnostic tools. Currently, BlueDot has their first consumer app, George, which provides the user information on environmental and health risks, based on their location or chosen locations, aggragated by city.

Wyatt is George's successor, which includes more personalizations, travel preparation, and a medical diagnostic feature.

Problem space

Easier air travel means easier spread of diseases. The North American traveller market needs a mobile and accessible solution for assisting them with their awareness, preparation, and treatment with regards to travel-related diseases. They need a tool that takes them an extra step further than preparation—which should ultimately get them to treatment in case of acquiring an infectious disease, especially while travelling.

"For assisting travellers with their awareness, preparation, and treatment with regards to travel-related diseases."
Prototype tested with 7 users (the symptom checking feature in conversational UI).

To begin with, factors such as climate, migration of animals and insect vectors are already changing and creating suitable environments for diseases to thrive in—alarmingly, even in environments they were not suitable in before. But most importantly, the unprecedented rate of international travel (surpassing 3.5 billion in 2015) parallels the rapid spread and increase of disease-acquisition risk of both old and novel diseases worldwide.

"The ease at which air travel occurs allows for diseases to spread within just a few weeks or days makes this a public health concern."

Wyatt is a travel health mobile app focused on preventing and resolving travel-related infectious diseases through travel preparation and differential diagnosis. Empowering travelers with information about travel-related health risks will help them avoid getting sick and spreading illnesses.

Design sprint

Google Ventures' Jake Knapp, Zeratsky, and Kowitz wrote a book in early 2016 about their design sprint process which claims to let you solve and test ideas in five days. This was the perfect process to incorporate in the new design of a consumer mobile app, given the timeline.

Long-term goals, sprint questions, and targets were established on the first day. After conducting a concept map and How Might We exercise with BlueDot's founder, I ended up with this final concept map. In this map arose the obvious targets to work with—the traveller and their research of travel preparations and medical-related conditions.

Next, various solutions were ideated and sketched, with competitors in mind for competitive benchmarking and remixing and improving upon existing ideas. These competitors were analyzed beforehand in a comprehensive competitive analysis done for 13 apps and services.

BD sketches
After using a computational decision matrix, the left solution sketch was chosen, and would later be known as Wyatt.
The final result included a feature of an environmental dashboard (much like a weather app) but showed summaries of concrete actions the user can do or be aware of based on the environmental conditions.

Moreover, a travel preparation section was created in order to give the user a more personalized pre-trip experience, while staying aware of any travel health implications their trip may have on them. Lastly, a symptom checker was tested to see how users would react to the chat format of a diagnostic tool, with incorporated keywords for a pseudo-chat feel.
User research

As a rule of thumb (or of Nielsen), 5 users are would optimally find 85% of all usability issues. Within BlueDot, 7 people were recruited through an interview screener. These participants were asked to answer 15 minutes worth of contextual and behavioural questions to validate or invaliate the persona hypotheses, and to gain insights from potential users' behaviours and attitudes towards health and travel.

The prototype test was done by asking the user to do two tasks: to get a travel checklist, and to get a potential diagnosis from Wyatt. The results of this study will be held confidential. However, Wyatt did lead to the iteration of George in a different platform—a chat bot, called GeorgeBOT in the next project.
