Mari is a companion for Parkinson's patients that provides them with emotional support and the opportunity to develop their speech and motor skills.


We were tasked with creating a voice ai assistant with a unique personality that responds to a particular problem space of our choice. The solution could be physical, digital or both.

More than 10 million people worldwide are living with Parkinson's Disease

provide emotional support by regularly interacting with a digital companion

encouraging the patient to develop and work on their speech and motor skills

bridge communication gap between patient and caregiver/family member(s)

How Might We make living with Parkinson's Disease more manageable?

Opportunity Areas


Voice AI

We began exploring how our device would speak to the Parkinson's patient and writing unique prompts for various situations. We then coded those prompts into the system using python.

When you ask a particular question mari responds according to the coded voice prompts. Here is the original device before modification.

We began exploring possible forms for our 2 physical prototypes: mari hub and mari fit.

Mari fit

We began 3-d form exploration of mari fit, creating more refined sketches as well as a pink foam model to test for ergonomics.

Mari hub 3d model

We 3d printed our final mari hub form with our logo design on top. The electronics for the voice AI would be housed inside. The device was then sanded and painted for the final piece!

Mari app

These are the key screens from the final hi-fi version of the app. Our app is primarily for the caregiver to see the status of the patient and communicate with them.

Voice Messaging

The caregiver or family member can view the patient's status with bar graphs as well as notifications about the patient's well being.

If the patient uses the app they can view different types of exercises with written instructions to accompany their training with mari fit.

The patient's contact information is provided as well as primary and emergency contacts for extreme situations.

The patient can send the caregiver a message through the hub. The caregiver can then reply to the patient through the app.
