BACKGROUND
During the Pandemic period, I went back to my homeland. Attending college remotely in a different time zone and having a full time internship at the same time caused me a hard time to balance my life and work. After living in this situation for 3 months, I went to hospital due to irregular heart rate. This symptom is called heart arrhythmia, which appears frequently in adults group who work in a heavy workload. Nowadays, health products such as iWatch are designed to track irregular heart rate and warn user about their body’s situations. Having an APP to record users’ personal healthiness data become a tendency for these health related products.
DESIGN BRIEF
In order to create a non-traditional technological healthcare product and minimize user effort in user interlace design,I designed a technological ring called FLOW. FLOW can trace users' heart rate by using heart rate sensors. To reflect the heart rate directly to users, electromagnets and ferrofluids are placed inside FLOW-the rate of electromagnets producing electricity are the same as users' heart rate so that the ferrofluids motion is controlled by electromagnets and move based on the users' heart rate. This process aims on mimicking the heart rate whenever users are wearing it, allowing users to observe their own heart rate based on the movement of the ferrofluids. Whenever the heart rate exceeds the normal heart rate range, which is 60 to 100 beats per minutes for adults, the ring FLOW would vibrate to notify users.
OBJECTIVE
I was one of the users who wore artificial intelligence watches to trace my healthiness. However.I wasn't constantly using the watch to track the data of mv health since it is recorded on an APP. After using It for several weeks, I forgot that it had the functionality to trace my healthiness.Therefore, based on my personal situation, the goal or this project is to design a health related product that allows users to check their health issues directly without going through APPs.
TARGET AUDIENCE
My target audiences are people who work or study 8+ hours per day and have a concern about their personal health issues. These groups of people are from different age ranges but share the same worry—how to track their health situations effectively without forgetting it due to busy schedules.
User Research
In the user research process, I interviewed people from different social backgrounds and age range. This interview is considered as an unstructured interview, which encourages interviewees to describe their personal experience with health related AI products and their expectation to these products. Then, a four quadrant diagram is generated based on the keywords in the interview.

Design Objective
Provide users opportunities to check on their heart rate whenever they want to
How
The product would be designed as a ring so that it is portable for users
Create a user friendly design that could increase user effectiveness.
The ring could mention users when their heart rate are exceeding or lower than 60-100 per minutes for adults.
Raise users' awareness to personal health
The ring could detect users' heart rate through utilizing optical heart rate sensors, which could measure the pulse waves which are changes in the volume of a blood vessel that occur when the heart pumps blood.
Product Functionalities
The product includes heart rate sensor that could record the heart rate through blood bump.
There are ferrofluids locate inside the ring that move in the same rate as users' heart rate.
The ring would vibrate to mention users when their heart rates are not in the proper rage.
Information Architecture
While users are constantly wearing FLOW in their daily lives, potential users might be interested in it due to its appearances and functionalities
Users would constantly wear FLOW
​
Users would be reliable to the warning system created by FLOW
Users would pay more attention to personal healthcare and visit doctors
FLOW would vibrate to mention users that their heart rates are not in a proper range
Attract New Users
Users who have heart arrhythmia
Heart rate not in the proper range
Users who want to track their health issues
Heart sensor detect the users' heart rate
Attract New Users
Wear FLOW daily to check their heart rate.
​
Users could observe the ferrofluids​
The movement of the ferrofluids inside FLOW could create a better understanding about users personal heart rate.
While users are constantly wearing FLOW in their daily lives, potential users might be interested in it due to its appearances and functionalities
Users would constantly wear FLOW
Users enjoyed the process of tracking their personal health due to the simpleness
Users who don't have heart arrhythmia
Heart rate normal
Prototyping
​To better understand how the movement of ferrofluid could be displayed by electromagnet, I built Arduino programs by using electromagnets and a heart sensor. In this process, the heart sensor constantly tests people's heart rate and produces the electricity on the electromagnet based on heart rate. Ferrofluid moves automatically based on the changing rate of the electricity.
I ​finished 3D modeling on Rhino. To embrace the product's concept, curves are utilized on the ring to emphasize the flowing of ferrofluids.
