Monitoring Physical Activity

Interaction Design | 5 week| Collaborator: MIA Health

I have worked on data visualisation of the Personal Activity Intelligence (PAI) score. PAI is a standard scoring system developed by NTNU's researchers that tells through numbers the amount of intensity-based exercise/activity routine an individual needs to perform weekly to achieve or maintain a healthy lifestyle.

​

Research says that if individuals maintain a consistent 100 PAI regularly (the score could go beyond), they are less likely to get chronic lifestyle diseases like cardiovascular diseases, diabetes, dementia, etc. A high heart rate results from a high-intensity workout that makes you reach 100 PAI (weekly metric) faster. 

​

It is a highly personal metric that measures intensity from heart rate data, and the result varies from person to person based on their BMI, age, body weight, height, Resting Heart Rate, etc.

MIA Health's vision is to build an intervention in proactive health care.

​

I designed for the user group at the beginner level of starting physical activity:


1. visual information of intensity during an activity.
2.
analyse the activities impacting intensity to help with their activity choices.
3. Activity
recommendations to earn PAI.

Image generated in DALL-E | Screen designed for final outcome by Arindita (me)

The intensity is measured through heart rate. The intensity increases with an increase in heart rate.

Design Brief

How might "Mia Health" best show personalised insight to users so that they feel empowered to take action about their current lifestyle choices related to activity?

Motivation: What would encourage users to do more things that are good for their health?

Key Insights

#1: The meaning of fitness differs for different people, and everyone has personal goals that vary from health goals for various reasons.

​

#2: People like references or recommendations to achieve their goals. To do the activity in the right way or just to know about different intensity-based activities that are also fun to do.

​

#3: When there is a standard fitness metric, not achieving it would be a demotivating factor.

​

#4: Many users do not clearly understand intensity-based exercise. They could only think of running or jumping-related exercises. And most people in these user groups do not prefer those exercises.

Quick Mapping of MIA health & PAI
Focus

#1: Empower user on how intensity-based activity impact heart

​

#2: Motivate people to explore intensity-based exercises (other than running and jumping)

​

#3: Defining how the MIA Health app is different from regular fitness apps

Challenge

During the research, it was challenging to make user empathise with the functionality of MIA Health because of the mindset around the existing fitness app in the market.

Final Design - Prototype
How is it different from other fitness app?
MPA_DesignPrototype
The design approach is individualistic and from a positive design stand point.
The new visualisation of PAI score in the app would not tell you the idealistic standard of fitness.
The user will have their fitness score goal set on their own at the beginning of their fitness journey
The colour of intensity dominant will motivate individuals to push boundaries to achieve the dominant colour in the dial. (Highest temperature of MIA's brand colour blue = Highest intensity)
The app would recommend activities to make physical fitness fun or to reach the score sooner in less time.
The colour dots around the PAI score dial are of MIA Health's brand colour in different temperatures (lower temperature = low intensity; higher temperature = high intensity). It represents intensities(low, moderate, and high intensity, respectively)
The dominant colour dots would reflect the intensity level of an activity a user has put into.
Design Outcome
1. Designed a dial that represent the intensity based on heart-rate data after doing a physical activity based on personal goal.
2. Re-designed interface of the digital app of MIA Health that would be based on the idea of humanising the data. Recommendations for a wider range of activities to help individuals achieve goals.
The dial is the heart rate of an individual using MIA Health. It is placed in the top section of the homepage. And, it would be the first data visualisation an individual would see after opening the app.
It is represented by the accumulation of dots with MIA’s brand colour with different temperatures to represent different intensities. 
Every individual will have a personalised coloured dial of heart-rate dots based on their intensity during physical activity.
Intensity 
Low
Moderate
High
I have chosen MIA’s brand colour to represent the high intensity and the temperature decreases with the intensity.
It is ideal to get 100 PAI to live risk-free from a chronic lifestyle disease. But an individual(beginner) can set their own goal during their busy schedule.
This animation is a representation of the intensity of physical activity, where each time an individual gets a score you could see your efforts in your physical activity through the dots.
The animation is generated in P5js to give a visualisation of the functionality. The colours are not in accurate form.
 “it works better for me if it is customised..it builds trust..if it is generalised then it becomes boring”. - User 4 
“Often, in the testing, there has been a talk about the suggestion of activities helps us to explore different activities to get into intensity activity without running or jumping” - User 1

Design Process

I used my service design skills to do an extensive research, to make sense about the theme, to align MIA Health's identity and their future mission and vision towards proactive healthcare aspect that starts with physical fitness.

Desktop Research
MIA hea;th's PAI sets a limit in physical activity by giving each individual a fitness score based on their heart rate and health information. It is different from other fitness application and devices available in the market.

INSIGHTS
Motivation Indicators
INSIGHTS
Mindset: The user often juggles between an adequate activity mindset and an inadequate activity mindset (the user cannot quantify the required amount of activity) leads to abandonment
Lack of personalised human data: difficulty in building long-term relationship, lack of engagement with user
Quantified-self
Day 1: Dance Routine
earned: 2 PAI
total score: 2 PAI
Day 2: Boxing
earned: 13 PAI
total score: 14 PAI
INSIGHTS
Boxing doesn’t include running or jumping and yet potential to reach high intensity
Running and jumping gives PAI score faster than other activities.

INSIGHTS
The meaning of fitness is different for different people and everyone has their personal goals which is different from health goals, for different reasons.
People like references or recommendations to achieve their goals. Just to do the activity in the right way or just to know about different intensity-based activities that are also fun to do.
Metaphor
Health Jar
“Some individuals do not limit their self-tracking efforts to passively collecting and observing gathered data about themselves, but rather develop it into forms of self-research and self-experimentation, also called “personal science”...personal science can be understood as an example of a more participatory and inclusive scientific culture driven by self-reflection, critical thinking and openness.”

User testing and iterations
First draft - Homepage
INSIGHTS
  • "With my busy schedule due to work, I may not achieve 100 PAI a week but I would like to have an option to decide my own goal." - User 1
  • "I don’t prefer running or jumping-based exercises but, I would like to have that as my option if it would help me score quickly." - User 1
  • "Hard to understand what my goal is and the connection with activities." - User 2
  • "Interesting to see the heart rate performance and the breaks within activities." - User 3
First iteration - Homepage
INSIGHTS
  • Confusion with the proportion of the concentric circle and the amount of activity done on each intensity and the differences in the representation of intensity in the main dial vs the overview
  • would like to know the activities intensity so help me choose activities next time - User 4
  • prefer the heartrate graphical format
  • the visualisation of PAI seems very interesting to me. I could understand the intensities translated into colors - User 3
Second iteration - Homepage
the lines on the chart gets removed on tap to have a clear picture of intensity by color
notification to update the acivity manually
recommendation of activities to score PAI
reflection of heartrate and intensity
user setting own goals
heartrate and intensity with activities visualisation
Future work
Sketching and testing more on the intensity and activities
question during onboarding about the activities the user cannot do to make the app more inclusive
need to work on colors for the overview analysis
