Mario Musa

Male, 41
Musician
From Sierra Leone

I recently obtained an older smartphone from a local NGO. Learning to operate the phone took some time as the icons were unfamiliar, huge learning curve on navigating the OS, and the phone didn’t support my native dialect. Additionally, because of local infrastructure constraints I only have access to WI-FI for 3 hours a day.

Current OS Problems

Usability issues

Context heavy UI design

Unfriendly gesture interactions

High power consumption

Cloud services reliability

Device unaffordability

Research

Early Stages

Wireframes & Template

Dark OS

The whole system is primarity designed for a dark mode, which would save a considerate amount of power for our users together with the OLED screen. Based on our research, the price of the OLED screen is not as pricy as before. We can find OLED solution with a better cost performance for our users considering the power saving potential. This choise solves two of the pain points at once.

Music App

The music player uses a wave form scrubbing interaction so that users can precisely find a point in a song with accuracy. Radio tab is for local FM/AM stations. Consistently users can save, favorite stations or scroll between them using the same scrubbing metaphor as the music player screen.

Home Screen

This 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 block buttons is meant to add more ease of use when launching Apps.

Clock

A world map is integrated into the clock app, which makes the world clock clearer than ever. 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.

Calculator

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

Phone

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

Health

Focuces on educating and making health resources more accessible for users. In addition to graphs and health data, the discover feature provides training videos, health 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.
