EVA is an AI device focusing on treating mental health through its whole journey with monitoring and therapy techniques. EVA is designed to replicate life, using the senses of touch, feel, sight, sound and movement to best connect with the user. Using the AI and embedded sensors the device can monitor you through your health journey and employ treatment to help combat health.

The Mental Health Journey

It was about 6 years ago when coming home from AFL my father was caught driving under the influence of alcohol, after going home while we were playing to go and drink. This was the start of the slow cycle downwards for where, over the years countless more incidents have occurred with the worst experienced with the combination of alcohol. This has not only affected my father but also our family, with many fractured relationships that has affected our health as well, while experiencing this mental change. Over the years I have continued to wonder how and why? I have been questioning the current methods of treatment and how we can better our health and, most importantly, limit the worst side of depression.

Less than 50% of people living with depression globally are receiving treatment as this big problem we are facing has inspired me into the topic of mental health, where we have seen the prevalence of this disease rapidly rise due to stressful living and tough times as it can impact a user’s education, work, relationships and cause disability. This illness is literally killing people with about 3,000 people dying each year in Australia from suicide, and the number have been rapidly rising since the early 2000s.

The research report rendered


The research phase of the project was conducted using action research, employing the technique of interviews and secondary research to best gather my data. I conducted this in two cycle phases, the first being with a former professor in facility of health at QUT and the next phase with a social worker at Currumbin Clinic and a patient who is also my user. From this I explore the disconnections between the current system where I extrapolated out important themes which included Rehabilitation, User Behaviour, Routines and Life Stages, Brain and Sound, Nature and body.

The user was the most important aspect of the project, luckily/unluckily I had a user for a primary source of information. This information was critical in empathizing with more users and mapping out characteristics and establishing touch points of which the product intervention could impact. Through all of the user data gathered my priority target market is those aged from 16 – 45 years old with still consideration for those outside this age.

The health Cycle

The most important aspect of health is how things shift, and the time where people experience different things, which can make mental health so unpredictable. To effectively make a difference to mental health we need to look at the whole journey from a current state to the downfall cycle, then to our worst state. Each aspect needs to be targeted so we can assess behaviours, signs, mood and what is our best self to develop relationships.

The user’s environment plays a huge role, where research found that rehabilitation can be used like a high and putting a user back into the world creates so many challenges, as finding that even the most safest of places, like your bedroom, can be the worse for a user with bad thoughts, stemming from this place.

Images of each phase of mental health

I envisage the best mental health system would offer treatment without stigmatising attitudes, one that genuinely acknowledges distress and validates a persons’ feelings and can offer assistance rather than judgement and advising a patient of what they can do to alleviate their distress and not to focus solely on what will NOT work.”

Problem and Goal

Lack in proactively recognizing life stages, risk factors and creating participation where there is a disconnection of Mental Health services/products and the whole cycle of health when experiencing daily life

To provide active therapy to a user and also allow monitoring of them through the whole cycle of health

Introducing EVA


Designed to stimulate life in a new form, EVA is here for us! Driven from research and development, EVA can help connect us back with life and how we treat our own health. The AI system will grow with the user and learn their strength and weaknesses using monitoring, tracking and voice/tone recognition with the combination of designed activities focusing on stress relieving, relaxation and understanding. This helps the device work together with the user to improve their overall health and combining both monitoring and therapeutic tools inside a small adaptable device can greatly improve the way we experience environments and the dynamic shift of health.

Usability and Ergonomics

Through research, I found stress comes from our upper chest region and this is where we feel it most. It was vital to target this region for the device to help a user through many different circumstances where stress maybe taking over. Through having the neckless we add a more personal attraction, as the user can choose for their preferred method of using the device. EVA will however promote the use of the neckless during activity sessions, where the device can better monitor and help regulate breathing with haptics on the chest region.

The retractable neckless has been designed for comfort targeting all types of user where they can adjust the length or use the device without it. EVA has been designed to be small and compact, making it portable which is very important to have the device with the user in different environments.
Back view of EVA


EVA monitors users in a variety of ways with the first being the embedded sensors in the device. The heart rate sensor on the back is used to track users emotional and physical state and also be used to connect their heart to others. The device will also track location to help provide users with knowledgeable information on where their worse health is located. EVA also has embedded pressure sensors which will be incorporated into daily activities and in the background used like a stress ball as EVA can gather data like the user being aggressive for example.

The AI of EVA will also be monitoring the user, tracking how users responds to it and the way they talk at certain times. EVA can do this through detecting how we speak and after time can identify how we are feeling from this. EVA will also use the sessions and general usage to help assist in accessing a users health state and how they can improve.

The interaction of EVA will evolve with the users journey, pin pointing the areas to best target each interaction and from this we hope to establish a connection with the user creating participation within the product.

Touch: Can be used to create a physical connection between the body and mind as we can stimulate several sensations that can be communicated with the brain. Here the device encompasses a soft feeling using silicone sides and the user can engage with some pressure and vibration activities.
Feel: Feeling can be categorized in two forms, being physical and emotional as the touch feeling is the devices hero with the shapeshifting top that creates an organic feeling and can stimulate life. The moving top can also be used for relaxation activities where it can better connect the device with the user.
Hear: The integrated AI system will be very specific with its communication where it will grow with the user and be personally tailored to their motivations and believes. The use of a virtual life form also can appeal to users more in opening up and expressing their issues and concerns. The device will also be applying Neuro wave sounds when appropriate which was shown in research to be the best brainwave to target calmness.
Sight: This relates directly with our environment and how we view living things and often seeing things provokes health in all sorts of way. Here the device will use light combined with its physical forms to help provoke mood and stimulate different emotions with the user.

App Integration

Perspective of Phone app and EVA device

The EVA app is designed to provide the user with more tools in their journey

Features in the app will consist of activity tracking, health monitoring, reflective and daily sessions, activities, guides, experience and exercise modes as well as destress/ breathing exercise options with also an option to connect with others. These features will add a more personalised feel to the user where they can better in-sync their experience and key goals.

If the user is diagnosed with a mental health problem then their will be an option for their doctor or close contact to have another app experience tailored for them to better connect with how the user is going. A key interaction here is when a user is in a critical state where the device can detect this and notify their close contact or doctors so they can get help where the device will enter a safety first approach.

The biggest feature that is incorporated into the app and device is the ability to send and receive heart beats where the user can physically feel it with EVA. This can provide a poetic nature of sorts in promoting life and letting the user know their not alone.

Inside EVA

The Assembly

The device is made up of 31 components all fitting within a 12.5 mm thickness body. The small size was vital in order for users to feel comfortable to wear and be portable. Joining the components will consist of mechanical fasting and adhesive where we can take apart the product and recycle for end of use.

The main body elements consisting of the frame which will be made up of strong Aluminium so that the device is durable and can hold the components. The side grips will be made of soft silicone for a comfortable fit in the hand and to allow a squishy feel. The top will also be made from silicone with a very slight Voronoi texture and the back will be made from a Sega fabric for its aesthetic appeal as well as making the device feel more soft and approachable. The fabric is used so that the mic and speakers can work properly as these elements combined help convey a sensory experience for the individual that is only amplified with all of its interactions.

The shapeshifting top will be achieved with the use of magnetic 3D printed shapeshifting polymer where we can program it to do different movements in response to a magnetic force. Their is currently huge potential for this to grow to being remotely controlled and to have huge impact within soft robotics and health. EVA controls the shapeshifting polymer using an electro magnet under the polymer which will have a series of different magnets with different forces that when applied the polymer will shapeshift into the flexible top.

The Process

Development record render

To design is much more than simply to assemble, to order, or even to edit: it is to add value and meaning, to illuminate, to simplify, to clarify, to modify, to dignify, to dramatize, to persuade, and perhaps even to amuse. To design is to transform prose into poetry.”

Paul Rand: A Designer’s ART, 2000

I believe that the process is the most important part to any design, without backing or informative information then the design cannot succeed. I strive myself on the process establishing a strong development record packed with research, concepts, development and continued iteration, following the double diamond process of design. The development of EVA encompasses 15 weeks of hard work where the first half was focused on research and initial concept moving to the second half focusing on prototyping and development of the design. From this I made my own plan to succeed with regular action and reflective plans to ensure I was meeting the requirements of each stage.

The Prototyping Phase

The prototyping phase started with basic forms and understanding the best shape for design. The initial prototyping was key for finding the off diamond shape that was inspired from a leaf designed prototype I made. The prototyping was most effective for establishing the size of my device starting from a thick part to slowly refining to a slim design. Refining each protype lead to the resolved design having a well thought out approach.

Final Models and Use

The final model was built as a look and feel model due to the scale of the design being very small. The model was split into two with one having the neckless attached and the other without.

EVA Implementation

EVA implemented into health cycle

Implemented into the four main health phases discovered through research, EVA will adapt to the user and their health. Through the general wellbeing phase the device will be less active and more used for entertainment like feeling music and movies. During mild symptoms the device will have more communication and mood/stress altering activities. Entering the depression stage the device will encourage more sessions with a focus on reflections and ways to improve, with additional stress/mood activities. When severely depressed, EVA will take a safety approach and let their close contact know and connect them. Here their close contact person can send them their heart beat to promote life or/and get help as EVA will employ slight interactions to boost back health.

Applying EVA to the whole cycle of health not only provides a better chance of establishing an ongoing connection but ensures we can navigate each phase a user may experience where we can prevent the worse from happening and promote the use of motivation and participation within individuals.

The EVA Health Journey

Everything that matters in living systems – what makes the difference between something living or not living – is motion, and motion is ultimately the result of shape transformation
