Project Proud Moments


My Contributions

  • Collaborated with a UX researcher to understand the needs & goals.
  • Led end-to-end design for the NeoRoo app.
  • 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 complications 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 conducted research in health facilities in Kenya to understand the challenges faced by care providers in saving pre-term babies. Her research uncovered shocking results on the severe shortage of expensive medical resources. Below are some of the pictures showing the need for affordable medical devices.


Due to travel restrictions during COVID-19 times, I did not have the opportunity to visit Kenya Health Facility in person. To help myself empathize with the user, I built personas' from the insights I gathered from the researcher.

Neowarm: A Patented Bio-Medical device

NeoInnovate team has developed a patented self-warming Device that utilizes wireless sensors to continuously monitor infants' vital signs (Temperature, Blood Pressure, Heart Rate, and Respiration Rate). The NeoWarm device has 3 modes.

What does NeoWarm do?

The sensors attached to the device detect the baby's temperature and alert through a 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 from when the device was deployed for testing.

Wiring the thoughts: Ideation Process

I received knowledge transfer and documentation from the researcher. I jotted down the pain points and created two user profiles: Family Members and Care Providers. Sketched an initial flow of the app covering the essential experiences for both the identified user profiles. From the research insights, parents and nurses needed an easy tool that could keep them informed throughout the intensive care period.

Information Architecture

Visual Guide


The face of the app: Logo Design

Ideated different versions of the logo to depict the app’s purpose with basic shapes. Narrowed down the options and flashed the final 3 versions to 10 diverse audiences. We chose the first one because the ring with ‘Helping Babies Survive’ had restrictions for open-source apps until approved by the HBS health council.

This app and Neowarm device can not only be used by the Mother, but also by anyone in the family. So, to be gender-neutral, I did not add any extra cues and kept it simple with geometrical shapes.

Transforming Ideas to Prototype

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

Feedback on Functional & Visual Cues
I sought feedback on very crude version of the screens from 2 researchers, 2 Interaction designers. Below are some of the feedback, I received.
  • Need work on color contrast
  • Needed a clear indication of baby's temperature that calls to action
  • Bottom Nav bar feels heavy
  • Search bar could be helpful to search from list of babies
  • Graph readings on X and Y axis can be straightened for easy read

Iteration 2

Feedback from Interaction Designers

High-fidelity: App Feature Highlights

After 3 Iterations, I came up with the refined version. Envisioned 3 modes of rings that are shown upfront to show the baby's temperature with color status (Matching the color in LED diodes of the NeoWarm device).

The design is based on minimalism and solid color to reduce cognitive load and provide an elegant design to the users of this app in restricted environments such as when offline or with low internet connectivity. Below are some of the feature highlights from the high-fidelity prototype.


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. I added two information tooltips to provide a summary of changes in vitals.

Temperature Bar

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


Parents provide 'Kangaroo Mother Care' but they have no idea how well they are doing as parents for their babies that need their warmth. This chart is visualized to equip them with the number of hours they provided Skin-Skin care. Added a goal line to reward their contribution to their baby's health.


Training modules with videos are super helpful for providing essential care when there are not enough care providers guiding the new parents.

User Testing

With the help of a researcher, I conducted a cognitive walkthrough with 9 participants in 2 sets. The group included a diverse set of participants from pediatrics, and biomedical departments. As there were ethical regulations needed to test the app overseas with real users, I chose a cognitive walkthrough approach to quickly get feedback on the complexity and learnability of the user interface until we have the deployable prototype. Overall, 90% of the tasks were completed effortlessly. The app is now developed and usability sessions with real users are being planned to be conducted on the deployed app.

In the deployed app, we plan to measure the below metrics


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

What I could have done better?

The project had plans for Participatory design sessions. Since 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 users in Kenya, understanding the user environment was essential to making ethical decisions on every interaction. Some of the major decisions were 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 a short span of time, I laid out different visual cues to gain feedback from different perspectives. I learned that iterations make a meaningful way for the product to stay robust in diverse users' hands.
