Background
Older adults often face cognitive, visual, and motor challenges when using mainstream grocery apps.
Existing platforms prioritize density and speed over clarity and confidence.
This project addressed how a digital grocery experience could be redesigned to support independence while reducing cognitive load.
Solution Overview: Shop Helper is a mobile grocery concept designed to help seniors shop with confidence—through clarity, accessibility, and human support
Large touch targets
44×44px minimum for buttons and controls, reducing mis-taps and making the app comfortable for users with limited dexterity.
Clear visual hierarchy and simplified navigation
A calm layout with clear categories and step-by-step screens helps users find essentials fast and complete checkout without confusion.
Voice-supported search
Users can search by voice or text to quickly find products, reducing typing effort and making discovery easier for first-time users.
The project followed a structured product design approach:
research → prioritization → system definition → usability validation.
Research & Insights
Identified common pain points including:
Small tap targets and dense layouts
Multi-step checkout flows
Lack of reassurance and confirmation feedback
No physical delivery assistance
Primary insight:
Confidence, not just usability, is the core barrier for senior users.
Product Strategy
Defined three design principles:
Reduce cognitive load
Increase interaction clarity
Integrate real-world support into the digital flow
System Design
Scalable touch targets and high-contrast typography
Clear action labeling and structured navigation
Built-in confirmation and feedback patterns
Testing & Iteration
Validated core flows with senior users and refined navigation, labeling, and confirmation states to reduce friction and increase task clarity.
The final concept demonstrates how inclusive UX decisions can reduce friction, improve clarity, and increase user confidence in essential e-commerce flows.
Improved Task Clarity
Simplified navigation and larger touch targets reduced confusion during search and checkout flows, especially for first-time users.
Validated Need for Assisted Delivery
User interviews confirmed that unpacking support and clear delivery communication significantly increased perceived comfort and independence.
Increased User Confidence
Clear confirmation states and step-by-step checkout reduced uncertainty and helped users feel more secure when placing orders.
