Android Mobile Application

Role: UX/UI Design Intern

Duration: August 2020 - October 2020

Team: SHIELD Engineering & NGC Design

Obtained average usability score of 84% for video streaming and data handling tool

Context

CAN WE BRIDGE THE GAP BETWEEN METROPOLIS PLATFORMS AND A METROPOLIS PRODUCT?

This project focused on designing an Android mobile experience for a turnkey out-of-box product utilizing NVIDIA's Deep Learning and IVA technologies.

Background

DISTINCT CUSTOMER GROUPS: SMALL BUSINESS USERS AND HOME USERS WERE IN NEED OF A MORE INTUITIVE SURVEILLANCE

I led the research and design of an Android mobile experience that would give users the ability to collect, observe and control video and data of important daily events digitally.

BUT WHY ROSIE?

ROSIE is a turnkey product, not a platform, meant to showcase superior inference and tracking software on real-world devices such as this Android mobile based experience. A complex product capable of supporting the needs of those who will use it.

Understanding the user

ARTICULATING THE USER JOURNEY OF 2 USER TYPES WITH 2 LEVELS OF USER ACCESS ON A MOBILE DEVICE

I started the formal design process with two user flow diagrams of touch points that users would encounter throughout their interaction with the product. This helped to visualize the experience of both the administrative side and user side of the app before moving into the wire framing stage.

Set up Experience (high - level)

In-app Experience (high - level)

Concepts of the core design

Developed concepts for onboarding, video player controls, data mapping, and parameter interfaces. Conducted regular review sessions with engineering teams to identify technical constraints and propose viable solutions.

Overall , most participants were able to

easily navigate/ understand the data

portion but the separate graph types were

unclear in the beginning.

Daily , weekly , monthly options

should be more apparent and

the other report buttons looks disabled

and un-clickable.

Getting to the video player was

deemed a little challenging for some

participants, but once there, navigation

was overall intuitive.

Recommendations for improvement

Based on user testing findings and stakeholder feedback, the following recommendations emerged for future development iterations:

1

Onboarding Optimization:

Ensure all copy is clear and void

of technical terms unless properly defined. This creates a smoother onboarding process for non-technical users.

2

Parameter Interface Design:

Clarify the relationship between parameter types, empty states, and named parameters to create intuitive card layouts and reduce user confusion.

3

Video Player Enhancement: Add relevant video controls in both Live and Pre-recorded views to reduce confusion about which mode the user is currently viewing

4

Data Visualization Support:

Provide tooltips or contextual copy when users first enter the data page to clarify differences between graph types and their applications.

5

User Management Workflow:

Implement automatic input of unique verification codes to enable quicker verification processes when adding new users to the platform.

Reflection

THE ROSIE APP IS STILL A WORK-IN-PROGRESS BUT A LOT WAS ACHIEVED

This internship overall was by far the most challenging but rewarding experience because of the fast paced, ambiguous environment. I enjoyed and appreciated the challenge of designing my first end-to-end product and it taught me a lot about being confident in the design decisions I make and speaking up about those decisions in larger meetings. This internship showed how beneficial it is to be a team player and having the opportunity to collaborate with other designers and engineers.

If I  had more time, next steps would be to implement the suggestions and recommendations received from user testing into version 2 of the mobile application.
