YouTest

is an at-home diagnostic device to test for various common illnesses including COVID-19.

Working on a team consisting of another industrial designer, a mechanical engineer, and a technical writer, we designed a diagnotic device, the UX for a mobile app, and instructions for use. The goal was to achieve the best industrial design and usability for end-users with little to no experience.

UX/UI development

I was brought into the UX/UI project to improve the digital workflow, and help to reduce possible use error. Working with a technical writer, we were able to improve usability while reducing risk of error by designing not only the app, but also the connection between the digital UX in the app and the design of the instruction manual, quick reference guide, and instrument.

User Stories

A

At Home

As a person who has a personal YouTest instrument and mobile phone at home, I want the ability to create a personal profile/account and/or dependent profiles to test myself and dependents.

B

School / Caretakers

As a nurse or caretaker who tests 5-10 children / dependent adults a day, I want to be able to set up an admin account so that I can manage my patients test's and export test result reports.

C

Company

As a company owner/manager that has many employees, I want one or several instruments that can connect to many phones so that my employees can test themselves when they arrive at work.

D

Neighboor / Roomate

As a neighbour or roomate of a person with a YouTest instrument, I want to be able to create a profile on my phone so that I can connect to someone elses instrument and run tests, but the results stay on my phone.

Problems & Risks

Admin flow vs. personal flow: does each user need a login?

How do patients receive results?  

How can we control privacy?

How does the app connect seamlessly from the quick start guide and user manual to the instrument?

User Journey

Early in the project, I participated in many brainstorming and ideation sessions with the client and with the internal team to discover usability solutions for this product. I worked with the team to create a detailed workflow map to identify areas where errors could occur.

FTUX Options

Based on the user stories, we created two FTUX login options. One option seperates by location and the other seperates by type of person performing the test. For users at home testing themselves, an admin account is not required.

Link between app & IFU

An important discovery we made after completing the user journey exercise was that the transition from the paper insructions to the app was confusing, and there were unessesary repeated steps and instructions. In the quick start guide, the user is guided to the point where the app takes over, and includes illustrations that match the steps within the mobile app to help users pair the two together more seamlessly.

Wireframes

Finally, a technical writer and I worked in Miro to develop a simple wireframe, from FTUX through to results. We focussed on the at-home user story.

Industrial design

One of my roles as industrial designer on this project was to create design intent CAD in Solidworks, and render CMF (color, materials, and finishes) concepts in Keyshot.

Instrument Design, Prototyping, & CMF Exploration

I sketched ideas for the design of the instrument. We explored mechanics to open the instrument and options for how the test cup would mate with the instrument, a critical requirement for the test to produce an accurate result. Finally, colour and finish options were proposed for the instrument including logo treatment, button labels, and LEDs.

Single-Use Disposable Test Cup

CMF Documents

Explored color coding options for the single use disposable test cups, each colour representing a different test type. Another challenge was creating a sealed lid for the test cup, so I explored options for a peel away lid as well as a full lid that clamshelled to the translucent base of the cup.

We also explored the shape of the cup itself and the usability of inserting the test cup into the instrument. We created a pokeyoke design so the cup can only be inserted in one direction, in order to reduce the possibiliy for error.

Graphic Design

I created final print ready files for an instructions for use manual and quick reference guide, and created packaging and labelling for the hardware and disposable components.

Instructions (IFU) Design

I worked with a technical writer to develop an operator manual and content for two trifold quick reference instruction booklets. One for the test (teal) and one for the instrument (grey). Created illustrations that were used in the final IFU and app.

Test Cup Labelling

We decided to use color coding to distinguish between test types. The label, the test cup sealing lid, the test cup QSG, and the packaging would all match the color of the test.
