01
Problem faced by people with CVD
In brainstorming for our project, three of our teammates discovered a shared connection: all our families are affected by cardiovascular diseases (CVD). This realization led us to explore how design could alleviate some of the challenges these patients face, especially considering the significant life changes post-surgery
Crowned as the leading cause of death in the U.S., coronary heart disease affects millions. Each year sees about 500,000 open heart surgeries, often involving complex procedures. Post-surgery, patients typically undergo major life changes and need extra care.
Our user`s persona
During the course we have had many interviews with 5 patients and a doctor (Cardiologist) and a medical startup owner. We also reached out to Health+Design Organization in RISD and got connected to some professions. We tried to understand the users as well as get an understanding of the industry.
USER SIDE
High Blood Sugar as a Side Effect of Heart Medication
Regular Hospital Visits for Blood Pressure Monitoring
Age-Related Increase in Medication Dosage
Risk of Diabetes from Medication
Dietary Adjustments for Heart Health
Early Signs of Diabetes
Medications Affecting Dopamine Levels and Mental Health
PROFESSIONAL SIDE
KEY TAKEAWAY
Post-cardiovascular surgery, many individuals experience drastic lifestyle changes and often need a family member for daily support. For those without a caregiver or whose family members are uninformed about their health, a smart assistant can be crucial to manage recovery activities and maintain communication with loved ones.
02
Ideation and prototyping
The majority of significant cardiovascular incidents predominantly affect individuals who are 65 years old or older. Recognizing that our users have a preference for physical presence within their homes, we aim to develop a solution that fosters an emotional connection with patients during their most vulnerable moments.
Form Iterations
We've designed a welcoming home assistant that interacts with our users through both its physical presence and an integrated digital interface.
System Mapping
We brought our prototypes to a senior house. We observed the life of a post - CVD patient for a day. We drew this timeline to conclude her daily life.
We recognized that surgery dramatically alters a person's life, and observed the numerous limitations they face post-surgery. From this understanding, we conceived LIVIA as not just a companion, but also as a facilitator for their daily life.
A key feature of LIVIA is its capability to integrate with other intelligent devices. Our initial model, a MVP (minimum viable product), is a smart ECG monitor designed to work in conjunction with LIVIA for everyday monitoring.
Refined User Journey
The depicted user experience demonstrates how LIVIA acts as a bridge linking patients with their loved ones who, though physically distant, deeply care about them. Additionally, LIVIA is designed to seamlessly integrate with the smart devices of others.

Final Product
Human Factors in Form
Interface on Device
We could map that daily routine on a timeline to facilitate a patient's everyday life. And we adapt the timeline to a wheel to fit our device's round screen. We also mapped out some key screens for the device.

How is LIVIA working with other smart devices
2nd Iteration based on feedbacks
Based on several rounds of critics and further talking to potential users. We get a lot of feedbacks, especially on the digital interface side. We made several changes and updates on a few aspects.
The LIVIA Interface
Our users, primarily aged 45 to 75, have difficulty recognizing small content on screen. In response, we've updated our interface with larger fonts and more distinct colors to ensure it's easier and more accessible for those managing this condition.
04
The Function-like Prototype
The LIVIA Device
The last step is to prototype the function-like prototype. A Raspberry Pie connects a 2.8-inch screen, led strip light, and a motor.
The ECG Patch
To test the device pairing function, we also build an ECG patch to pair it with our device.
Testing on Users
The project also won the Brown RISD Capstone Project Prize and is featured on Brown engineering school`s official account.
