Problem Discovery

Problem infographics v7-01.png
 

Expert interviews

Experts at local mental health charities were approached for interviews for insight into the problem domain

‘‘Its better to prevent the problem than to firefight it’’

Key insight from mental health experts, changing the focus from a reactive to preventative.

 

What’s influencing mental health in the UK?

Market Segmenting

Millennial workers are uniquely effected by modern trends leaving them vulnerable to an inability to recover from work stress.

Targeting the worst effected user group means the product will have the largest impact.

Key Expert Insight

People don’t realise the damage we do though out the day that stops us from switching off after work. Stress is caused by life style, so we treat it holistically.

Market Review

POSITIONING MAP-01.png

Positioning Map

A review of the wellbeing market revealed an unfulfilled need and a strategy to differentiate the product: Passive therapy.

This, paired with user and expert insights, forms a design specification to evaluate ideas against.

 

Themes

3 Key Pillars of Mental Wellbeing

Design Brief

How can we improve the mental wellbeing of millennials to reduce stress levels holistically throughout the day, allowing them to switch off after work, as a preventative measure against mental illness?

Concept Generation & Evaluation

Final-sticky-mock-up_em-edit.jpg

CoDesign Brainstorm

Concepts were generated around sensory therapies for mood regulation, modern sleep rituals and incentivised exercise.

Sensory therapies was the most fitting to the design spec, as it can be made passive through automation.

 

Sensory Therapies

After creating concepts around sensory therapies; it was clear music has the potential to support and enhance all three pillars of mental well being therefore the clear direction to develop further.

ISO-Principle Music Therapy: The Neuroscience

Emotional or Physical changes using musical frequencies

The discovery of ISO principle gave the methodology for how music will be used to alter emotional states, for mood regulation, and physiological states, for sleep and exercise.

 

Experience Development

ISO-principle music therapy for mood, exercise or sleep product scenarios visualised.

 

Primary Need Discovery: Co-Design Workshop

final codesign pics-01.jpg

Primary User Need: Mood Regulation

The workshop revealed the users top value through an exercise of marking what was most important to them, then these were related to features of the product which they were asked to put into order of importance as a group.

Mood regulation proved to be the users primary need, so will be the main feature of the solution with biofeedback and automation.

 

How can we automate mood regulation for passive therapy?

Human emotion and music emotion can be read and plotted on the same 2D valence-arousal graph of emotion.

Interaction Development

Metaphor UIv2-01.png

Metaphor of Colour

The metaphor of colours will be used to break down a complicated system into an easily understandable user interface.

Colours semantic value allows for a colour wheel to represent the 2D graph of emotion. This may differ between cultures so an initial set up process will be needed in the app.

 

System Design

Creating a system which continues to learn and become more effective and personalised, the more the user wears the earphones and interacts with the interface.

Emotion Sensing Using Biometrics

Emotion sensing using low-cost sensors with ‘synchronisation’

A scientific paper states teaching the system which physiological signs relate to which emotions for that specific user, a ‘synchronisation process’, will result in 85-95% accuracy of predicting the users emotional state.

 

System Simulation

A mini system was developed to create a simple stress circuit, using a neo pixel ring to simulate the interface.

Form Development

Electronic component consideration:

Focus Group Feedback

Sketch models representing different methods of receiving the music therapy were presented to a focus group of users who gave feedback on their preferences.

Earphones were the most preferred and suitable, therefore will be taken forwards to develop further.

Travel Case & Speaker Base Ideation

A travel case for portability and optional conductive charging base for sleep activities created the product family.

CMF

The chosen CMF has the same visual language as the mobile app, to create a coherent brand.

The design language incorporates curves organic to reflect waves, a theme throughout the branding, to represent both sound waves and the biometric waves registered by the sensors.

Accessibility and the mental health crisis among teens

Without the wearable element, the mobile app enables interactions with music for mental wellbeing. This is a highly accessible way to support vulnerable people, for example, teenagers who are currently facing a mental health crisis. The apps low price point and the widespread appeal of music, makes it an ideal element to continue to develop after the hand in to create a positive impact.

Thanks for looking, hope you found it as interesting as I did :)
