Problem Define

Major audience and pain points are identified in this sprint. User research, Objective and Design principles are defined.

Design Process


Design System

Testing wireframes and build a library including typography, page structure, color palette, icon set, and other components.



In the final sprint, Apps are refined based on critiques and finalized for presentation.


Apps Design

Creating core apps based on the design principles defined in the earlier sprints including iteration and testing.

User Research & Personas

Our team decided to focus on creating a mobile operating system for those who live in the global south. We went over 6 existing research on our targeted areas and users. Some main user pain points are low affordability, lack of access to power and data, and travel difficulties. Based on the research findings, we created two user personas.

Research key takeaways

Most electronic devices are not affordable
for our targeted users

Users have extreme low access to
power and cellular data

It often takes users a long time to travel
to banks and health facilities

Competitive Analysis
Why doesn’t Android or iOS work?

Usability issues

Context heavy UI design

Unfriendly gesture interactions

High power consumption

Cloud services reliability

Device unaffordability

Design Principles




High Contrast




Flat Structure





Early Stages

Wireframes & Templates

Dark OS

The whole system is primarily designed for a dark mode, which would save a considerate amount of power for this user group together with the OLED screen. Based on research, the price of the OLED screen has become inexpensive. We can find OLED solution with a better cost performance for users considering the power saving potential. This decision solves two of the pain points at once.

Music App

The music player uses a waveform scrubbing interaction so that users can precisely find a point in a song. The radio tab is for local FM/AM stations. It uses the same scrubbing metaphor as the music player screen which allows users to switch between different radio stations.

Home Screen

The home screen is on track with the design principles. Communicating a design that is minimalist but also has icons that are identifiable to someone who may not be as technologically literate. Additionally, the use of bigger block buttons is to add more ease of use when launching Apps.


Simple but highly functional following universal and flat structure principles. The analog screen is very familiar design. Function keys are in different colors and contrasting so that important functions are easily identifiable.


A world map is integrated into the clock app, which makes it more functional. Users can understand the time differences just at a glance. Additionally, users can zoom in/out on the map to refine their time zone selection.


The dialer screen has shortcuts such as “Mom” to minimize the steps users need to take to make a phone call. The contacts tab has a slider on top to find targeted contacts in a short amount of time. Added the message and call shortcuts to increase efficiency.


It focuses on educating and making health resources more accessible to users. In addition to graphs and health data, the discover feature provides training videos, healthy recipes, and articles. When needed, It also has a chat function where users are directly connected with volunteering international medical professionals to ask general questions and get support.


The process of designing a system rather than one single app gave me better insights into how high level design thinking works. Completing this project made me realize the world moves at a different pace. Today, the mobile operating systems we are accustomed to only involve around certain groups of people. I learned that it is extremely challenging to design for all due to differences in culture, language, and lifestyle. However, I also learned that there is a space for a new operating system that focuses on simplicity and functionality. That is what we tried to achieve with this project. An OS that connects people living in rural areas around the world. Further research is still required to better understand people's lifestyles from different parts of the world which would greatly help improve ConnectOS.
