HealR - UX Research for Tele-Healthcare Software

Introduction:

With the use of telehealth, also known as telemedicine, your doctor may treat you without having to see you in person. The majority of telehealth activities take place online using a computer, tablet, or smartphone with internet connectivity. The app must be simple to use because it will be used by both technologically knowledgeable and non-technical users. After assessing other telehealth applications, like MDLive, Proactive for Her, I had a vision for how our app should look and what functions to include.

Problem Statement:

"How can we make our telemedicine application stand out from the competition by employing a user-centered interface design and adding both standard and special features?"

Project Methodology

Discovering the functions that needed utmost attention:

Background Research

• Reviewed case studies of telehealth applications

• Downloaded and tested telehealth applications on the Apple App Store/Google Play Store

• Researched common functions for telehealth websites and applications

Narrowing Down the Functions

• Individually created “possible functions” list

• Team collaboration to determine final list

• Ideation session for tasks and subtasks under each main function on Miro

• Created multiple drafts of HTA diagrams

Hierarchical Task Analysis (HTA)

Application Design Brainstorming & Prototyping

Preliminary Design Work and Brainstorming

• Each team member reviewed UI/UX of telehealth applications

• Interviewed 4 users about the UI/UX of MDLive telehealth application

• Researched telehealth application desires from users

• Ideation session on features to include and the overall look and feel of the app

Prototyping Methods

• Each team member selected a function to create low fidelity hand sketches

• Reviewed sketches as a team and determined final design

• High fidelity wireframes were created in Figma and prototyped in order to produce a clickable prototype of the app

Medium-fidelity Prototypes

Usability Evaluations

Evaluation Approach

• Quantitative Analysis (8 participants)

• Retrospective Think Aloud (8 participants)

• SUS Analysis of Survey Response (8 participants)

Methods and Metrics

• Test existing MDLive app and prototype in random sequence (avoid bias)

• Measure task completion time (sec), task success (pass/fail), and number of errors

• SUS usability scale

Participants

• Participants ranging in different age groups and genders

• Age range of 25-62 years of age

• 4:4 male to female ratio

• Recruited through friends, family, and classmates

• Performed usability test with 8 participants
