The Project

In this project, I developed a comprehensive design system for point-of-sale (POS) user interfaces across a diverse range of touch-only devices. The aim was to create a unified and intuitive user experience that enhances usability, efficiency, and accessibility for both cashiers and customers in retail environments. 

Project Goals:

• Unified Experience: Establish a cohesive design language that ensures consistency across different touch-only POS devices, regardless of screen size.

   

• Intuitive Interaction: Design intuitive touch interactions that streamline the checkout process, reducing transaction times and minimising user errors.

   

• Accessibility: Prioritise accessibility features such as contrast, font sizes, and interactive elements to ensure usability for all users.

   

• Scalability: Create a scalable design system that can accommodate future updates, new features, and additional device integrations without compromising usability or visual coherence.

Foundations

Stablished a visual language including color schemes, typography, iconography, and feedback animations that enhance usability and brand identity.

Atomic design 

Tools

I utilised Figma for designing and prototyping the UI. Zeplin to translate designs into developer-ready specifications, enhancing collaboration between design and development teams and Jira, that facilitated efficient project management, enabling seamless task tracking product development.
 

Components

Defined a set of reusable UI components (e.g., buttons, forms, menus) that ensure consistency across the design system.
