Designing a healthcare service for people with food allergies

‘Spoonful’ service consists of two parts: Smart flatware and an application. Smart flatware enables people to detect allergens right before eating food. The app helps people track their eating history, communicate with doctors, and search for allergen-free products.

Problem Context 

1. Food allergy is prevalent
in America

As food allergy affects 1 in 10 adults, 1 in 13 children in the US, food allergy becomes major health concerns among people.

2. Over half of people who have food allergy have experienced severe symptoms

A food allergy is like a silent killer. Sometimes allergy reactions to food can be severe, and life-threatening.

3. The allergy diagnostic and therapeutic market size is growing every year

Rapid urbanization, pollution, and poor dietary habits increases the incidences of allergy conditions across the globe. While 50 million Americans are affected by allergies every year, there is no effective cure in sight for food allergies.

Problem Statement

How might we help people who have food allergies discover allergens prior to eating
so that they feel safe?


Competitor Analysis

I chose three major allergy detector companies to evaluate their services and discover opportunity areas. Based on my insights, I created seven parameters: Ease-of-use, The number of allergens that can be detected, portability, price, allergy information support, accuracy, and time. The competitor analysis produced the following insights.
Opportunity area: Ease-of-use, allergy information support
To use most detectors, people must insert a piece of food into the device and wait for a while. In terms of requiring extra work, it is not an intuitive way to detect allergens.

Service requirement: Portability

The size of competitive products is small and handy because people should bring a device everywhere.

➌ Technical issues: The number of allergens, time, accuracy, price
There are four technical factors that I cannot determine. Though these issues are beyond UX design, time and the number of allergens are relevant to usability. I decided to focus on the two factors: opportunity areas and service requirements.

User Journey Map

To map the user journey. I set up three major situations where people could use the service.
  1. Eating a home-cooked meal
  2. Grocery shopping
  3. Finding and eating at restaurants

Depending on the situation they face, people will have different goals, actions, and touchpoints. On the other hand, the flow is affected by their symptoms.
