Aterica Digital Health - iOS app design
An IoT application that connected people living with anaphylaxis to a support network of care givers and family members.

This was achieved by monitoring real time location and temperature data of a medical Epipen device and sending updates to the network in the event of an emergency, the user could also get reminders if they left the house without their device or if it was stored in a location where the ambient temperature could impact the quality of the epinephrine. 

Epinephrine is the life saving medicine within the device and can lose it's potency within hours when stored in a hot car or exposed to prolonged heat. Epinephrine has a recommended storage temperatures of 68–77° F with a ~tolerance with 59–86°F, anything beyond the tolerance would tigger a notifications that the device was getting to warm.
Senior UX/UI Designer 

I was the Senior UX/UI designer throughout the projects MVP cycle, from planning and requirements gathering to journey mapping, wire framing, usability testing and interaction design. Continuously collaborated with the hardware and software development engineers to brainstorm ideas and problem solve in an agile work environment.

Main areas of responsibility:​​​​​​​

Experience design strategy and analysis, journey mapping, personas, wire-flow diagraming.

Lo-fi to Hi-fi user interface design, sketching, mockups, rapid prototyping, detailed and accurate compositions of layout using retina optimized 2X images and scalable vector assets.

Interaction design, working in tight communication loops with a frontend developer to iterate and dial in how the application feels when a user experiences the application. 
Project summary

Aterica digital health was an IoT startup that allowed parents with children who are anaphylactic to know if their child was in safe proximity to their medical device. 

The high octane that comes from problem solving and executing in short sprints against an increasingly shortened run way is why I loved this environment. Designing an application experience for a network of personas connected to a physical object was incredibly challenging to say the least. I learned how users interact with an iOS vs Android, which at that time I was an Android user myself so I was heavily biased towards google's Material Design patterns and not accustomed to how iOS shaped their native GUI functionally. User research and testing allowed me to remove my personal biases and select design patterns that iOS users were accustomed to.  


The challenge

User needs:

With this application redesign, Aterica Digital Health wanted to bring more focus and attention to the network of users who surround someone with Anaphylaxis and understand how the physical object would translate information to a mobile device.

The medicine was sensitive to long periods of heat exposure so the sensor would activate a state change state in the user interface showing the device is getting warm, allowing the user to take proactive action before it's to late.

Business requirements:

Aterica had a basic UI architecture strung together but not a design that was user friendly. They wanted a functional and user friendly interaction design.


The solution

Pain points the new experience solved:

The application gave care givers reassurance that a child was within proximity of their life saving medicine at all times. Real time location data was available at all times and most importantly in the event of an anaphylactic shock, in this scenario the device would send a notification to the entire network if the lid was ever opened and the EpiPen slid out of the smart case. 

The experience was designed to mitigate notification fatigue, caregivers in the network were never notified unless it was to signal that a high risk event has occurred.

A child leaving the house and forgetting their medicine would trigger a local notification only, the child has an opportunity to go back and pickup the forgotten device or use the "find my device" feature from the mobile app and if needed trigger a sound that would help aid in the recovery of a lost or misplaced Epipen. 

In the use case scenario where a child is experiencing an anaphylactic shock and needs to use their EpiPen, they remove it from the Veta smart case and a sensor would trigger the highest risk notification and display that message out to the network of caregivers, showing the child's exact GPS coordinates. We designed false positive mitigation strategies into the UI so that the user had a 10 second buffer to cancel a notification in the event of a false alarm.

Execution

Used design discovery methods, persona development, user journey mapping to identify all the actors in a system and design interactions to meet their needs. 

• Persona development for multiple user types and the caregiving network allowed for consistent team communication when framing challenges and keeping the team user focused.

• Risk mitigation strategy, design thinking, team collaboration and clear communication.

Designed and shipped the first end to end iOS experience for the Veta smart case product giving caregivers the ability to visually see if a child is within proximity of their EpiPen instilling a sense of real time reassurance.

Results 

Implemented design interactions that were grounded from discovery research and user testing insights which led to the successful iOS MVP product launch in 2017.

Lessons learned:

Systems thinking.

• Design patterns for iOS.

• Learned to design against new environmental constrains. We used the interface to display network and bluetooth disconnection errors when dealing with bluetooth signals dropping out due to wireless spectrum signal interference when device is within brick enclosures or near active microwave frequencies. 

Reflections:

CES 2016 Innovation Award – Honouree for its Fitness, Sports and Biotech category and recognized for:

Aesthetic and design qualities
Engineering qualities
User value
Product uniqueness
Feature attractiveness

A team of CES multidisciplinary designers describe the new Veta design as: 
“a design that fits into its user’s daily life and simplifies anaphylaxis vigilance through automatic monitoring and connectivity. Veta’s sophistication is concealed in its simplicity.”
