This is a design developed for the course Health & Psychology and we have worked with the Heartisans wearable as an example.

How to use a device as a tool to have a better diet and prevent future heart conditions?

The goal of this work was to answer this question by designing a service that could be partnered with the Heartisans Watch, a  cuff-less blood pressure watch currently available in the market. 

The goal of the  service designed is helping users to improve their diet, or make informed choices, and, therefore, being able to prevent heart conditions in the long term, by using the device as a tool for health awareness. 

Blood pressure: Why does it matter?

Blood pressure is known as a “silent killer”. It does not present clear symptoms and puts the heart and the blood vessels under extra strain, increasing the chances of a heart attack or a stoke in the long term. Moreover, it can cause heart and kidney disease.

Eating healthy and avoiding blood pressure spikes contributes to keeping healthy blood pressure values in the long term. Diet programs like the DASH diet approach this issue and have been taken as an inspiration.

Conversely, different foods have different effects depending on the individual. Therefore the value that the device provides is acknowledging through measurements what actually has an impact on your health.

The target group

Young people from 25-35 years old  who want and are curious to know more about their own health.

Key attitude towards the problem:

They like the idea of keeping health, lack the knowledge in terms of blood pressure, feel unnatural to measure blood pressure regularly at that age.

We have chosen International Master  students to represent young people with no worries about their heart due to the following reasons and assumptions:

International students have to adapt to different eating habits according to the ingredients available in the country that they have moved to.

The students in the University where the study was carried out are mostly aged between 25 and 30 years. Therefore they have more awareness regarding their health, despite rarely presenting any health issue related to eating habits.

They face periods (ex. Exam-weeks) when they are under a lot of stress and therefore may opt for non-healthy food.

 

To be able to understand better our group’s attitudes towards diet and measuring Blood pressure, we have organized a workshop with 7 participants about wearables, blood pressure and diet.

We have used context mapping methods in this workshop.

Constructs from the Theory

We have connected our insights with the Integrative behavioral Model. This has allowed us to understand how to design a service that could help the user to change a behavior.

Designing the service

We broke down the Service into four main phases:

1. Instructional

This phase is dedicated to raising awareness regarding diet and Blood Pressure and why it is important to keep healthy values of blood pressure.

2. Preparation

In this phase, the user calibrates the device and sets a baseline of values for his Blood Pressure

3. Measurement

In this phase, the user gets to know what kind of food, mood, and activities has an impact on his blood pressure. Furthermore, the user receives suggestions on how to improve his values when the measurement accuses a value of pre-hypertension. E.g. how to decrease the sodium in a meal.

4. Diet advices

The user receives a personalized healthy meal plan that takes into account: Budget Food preferences Location Personal goals

Zooming in

We have focused our attention in the two first layers: Physical evidence and the Customer Actions.

Adaptation loop

We believe the service and the device could evolve through time. We thought about how the device would adapt into the user’s life. To do that we developed an adaptive loop from a “Thing” perspective.

Validating it

To validate our service we have tested a mock-up with 4 participants and we have iterated on the results. Based on the feedback we could fix some usability issues and think about how this service could evolve through time.

Reflecting about the evolution of the service

1st Horizon

An Interactive meal plan.
The user receives a list of ingredients and a selection of recipes that matches. When deleting or adding a new ingredient, the recipes are updated.

2nd Horizon

Discounts and partnerships with Supermarkets. The user gets a list based on ingredients that are sold with a discount. Special bonus and promotions could be designed to stimulate buying healthy ingredients.

3rd Horizon

A menu advice Partnerships with delivery companies. When accessing online delivery websites or apps, the user would be able to see an overlay with a stamp identifying dishes that are healthy options. When clicking over them, the user can know why they are a good or a "bad" option in terms of spiking the blood pressure.
