NeoRoo is selected as finalist in Global Health Innovation conference


My Contributions

  • Collaborated with a UX researcher to understand the needs & goals.
  • Conceptualized interactions, user flow and other marketing visuals.
  • Prototyped end to end workflow and Handed off designs.

Project Background

Every year 15 million pre-term babies are born. 1 million of them die due to pre-term birth complication and many survivors face lifetime disabilities - World Health Organization (WHO)
Common complications include

How is Hypothermia currently handled?

Radiant Warmers
Kangaroo Mother Care

However, the above 3 methods have several disadvantages

Identified Painpoints

Dr. Sherri Bucher researched with health facilities in Kenya to understand the difficulties faced by care providers in saving pre-term babies. Her research uncovered shocking results on extreme shortage of expensive medical resources. Below are some of the pictures proving the need for affordable medical devices.

Introducing Patented Bio-Medical device

NeoInnovate team have developed the patented self-warming Device that utilizes wireless sensors to track pre-term babies and continuously monitor infant's vital signs (Temperature, Blood Pressure, Heart Rate, Respiration Rate). The NeoWarm device has 3 modes.

What does NeoWarm do?

The sensors attached inside the device detects the baby's temperature and alerts through change in diode color. The device was tested with the users for comfort and proved to be technically, economically and legally feasible for an affordable price. Below are some of the pictures when the device was deployed for testing.

Need for an handy app: Feature Highlights

From the research insights, parents and nurses needed an easy tool that could keep them informed throughout the intensive care period. I envisioned 3 modes of cards that is shown upfront to show the babies temperature with color status (Matching the color in LED diodes of NeoWarm).

Throughout the design, I followed minimalism to reduce cognitive load and provide an elegant design to the users of this app. Below are some of the highlights


Icons accompanied by labels unleashes the power of iconography. Using Icons that are universal and intuitive contributes to reducing cognitive load.

Tool Tip

Seeing an 'i' icon on the chart, users tend to click for more information. Following the metal model of the users, I added two information tooltips to provide a summary of change in vitals.

Temperature Bar

When the user sees a graph with readings on 'Temperature', they always think back to process what the number means. Eg. 37.5 degree is normal.
Using the stacked color bar (Resembling a thermometer) on the 'Y' axis of the chart provides easy way to infer the temperature readings shown in the chart.


Parents provide 'Kangaroo Mother Care' but they have no idea on how well they are doing as parents for their babies needing warmth. This chart is visualized to equip them with number of hours they provided Skin-Skin care which contributes to healthier babies.


Although, the medical facilities provide instructions for parents, when there is scarcity of resources, The training module with videos are super helpful for providing essential care.

Wiring the thoughts: Ideation Process

I received knowledge transfer and documentations from the researcher. I jotted down the painpoints and created two user profiles: Parents and Care Providers.

Final information architecture

Transforming Ideas to Prototype

Iteration 1 (Please click the image to view a clearer version)

Feedback on Functional & Visual Cues
I sought feedback from 2 Researchers involved in the user research and 2 Interaction Designers Expert from Industry to refine the prototype. Below are some of the feedback, I received.
  • Using gradients might make the users hard to read the contents
  • Iconography can be improved
  • Needed a clear indication of baby's temperature that calls to action
  • Bottom Nav bar feels heavy, can bring focus only on the active icon
  • Introducing search bar could be helpful to search from list of babies
  • Graph readings on X and Y axis can be straightened - Easier to read

Final Prototype

After 3 Iterations, I came up with the refine version. You can play with the prototype by scanning the QR code through your mobile


Working towards a cause that could provide voice to voiceless babies feels great. This project specifically expanded my visuals skills and I am thankful to all my teammates & industry experts who provided valuable feedback to iterate, brainstorm and finalize the product design to help the needy.

What I could have done better?

The project had plans for Participatory design sessions. Since the traveling was restricted during COVID, I had limited resources to interact with users. However, researchers who visited health facilities were able to provide feedback to improve the product.

Biggest Learnings

Designing with Constraints

Since the app is specifically designed for people in Kenya, understanding the user environment was essential to make ethical decision on every interaction. Some of the major decisions was made for
1. Choosing to design for android
2. Handling low / no internet connectivity
3. Different levels of user literacy

Incorporating Minimalism

The device is expected to work seamlessly in the health workflows. So, the design is required to minimize the cognitive load in every possible way by keeping the minimal design principles at the core.

Quick Iterations

In short span of time, I laid out different visual cues to gain feedback from different perspective. I learned that iterations makes a meaningful way for the product to stay robust in users hands for long time.
