GRACEFULLY

Project

GraceFully

An online food delivery service that is designed to cater to the unique needs of the senior demographic.

This is a semester project where I had to conduct user research and develop a elderly digital product with my team. Our primary goal was to resolve the challenges many elderly individuals face in meal preparation and ensure they have enjoyable food options with our service. My role was to conduct user research while taking the initiative to lead the team.

User Research

During our interview process, we chose to target seniors within the age range of 52 to 76 to be our participants.

To engage with potential senior users for this service, we conducted in-personal interviews in a semi-structured manner.

expressed frustration with apps that required excessive steps

Discovery #1 - Accessibility:

User-friendliness were highly valued, with a specific desire for options like larger text for improved readability.

Discovery #2 - Data security:

Users wanted to feel confident that their personal information, especially payment data, was not vulnerable to breaches.

Intuitive User Interface

Simplistic design with straightforward instructions on a navigational interface enables our customer base to easily access our service to browse and purchase

Concise Payment Instructions

Clarity in payment instructions for the elderly customer base to feel safe and confident with online transactions.

Accessibility Accommodations

Options to adjust tiny font sizes and descriptive images to cater to those with visual impairments

Detailed Nutritional Information

Allows the users to understand the information they need for their well-being, especially those with specific dietary restrictions or health conditions

Task descriptions

Based on the data obtained from interviews, we created user personas and established task description, thus created a tentative list of requirements for the app.

Categories of the list:

Must include (shown on the left side)
Should include
Could include
Exclude

The list helped us to consider features to focus on during the design process.

App Flowchart

Paper Prototype

Cognitive Walkthroughs of Paper Propotypes

After building paper models of the online platforms for both desktop and mobile views, we chose to adopt cognitive walkthrough as an evaluation method, which was efficient for the investigation to identify the concrete research area and goals in the design stages.

Key findings

the platform demonstrated intuitive and centralized navigation with a consistent structure, underscoring the aim of easing user flow
the primary area for improvement was the accessibility of dietary customization to be more visible
supplementary incorporation of a user feedback component would also be beneficial

Task #1: Meal customization for dietary needs

Insight:

difficult for users to access the customization option
clarity of terminology used for the dietary preferences

Improvement:

introducing more prominent prompts as visual cues on the main menu
suggesting a user-friendly and streamlined process for the users once they can access the customization feature

Task #2: Ordering and tracking the delivery

Insight:

showcased a straightforward process for users to order and track the delivery
flexible payment methods catered to the capabilities of the elderly demographic

Improvement:

suggesting a user-friendly and streamlined process for the users once they can access the customization feature

Heuristic Evaluations

We conducted two summative evaluations studies, aiming to assess the readiness of the high-fidelity prototype for the platform. By recruiting participants with relevant knowledge of UX design, the study simulated real-world usage scenarios to validate the platform’s usability and effectiveness.

Framework

Evaluation criteria: Nielsen’s 10 usability heuristics
Issue evaluation: 5-point scale

Issues to address

Pre-existing allergies or dietary limitations

Dietary customization when onboarding
Products include detailed information, displaying nutritional values
Uses algorithms to provide personalized meal recommendations based on user preferences

Lack of Visual representation

Interactive Shopping Cart
Enhanced Navigation (“Back”, “Edit” buttons)
Favourite Features

Potential visual impairments

Voice-over support
Color blindness mode
Adjustable text size for improved readability

Difficulties in navigating technology

Support and FAQ Features
Convenient Payment Methods: Incorporation of cash-paying methods
Implement onboarding video tutorials within the app

GraceFully Design system

Establishing a design system and formulating design specifications creates visual efficiency in the user interface.

An online food delivery service designed to cater to the unique needs of the senior demographic.

Retrospective

First UX UI Project!

This was my first UX UI project. From designing and conducting the evaluations, the team was able to create the high fidelity prototypes with evaluations within 2 months. Due to the time constraint, we were not able to further enhance the overall usability. Nevertheless, I believe that this project serves as a foundation for me to develop my career path into the field of user experience.

01: Leadership is important

During the project, I found leading the team is more challenging than I expected. By breaking down workload into a structured team framework, I learnt how to solve team conflict through internal communication.

02: Empathizing is difficult

Through taking into concern variations in the internet, user scenarios, and possible issues distinct to different ways of life, this bigger assessment approach seeks to show how the app works in a variety of settings. I learned that it is crucial to carry out tests in different circumstances to understand our app's real-world performance.
