Overview
This case study examines the potential of CMYK 2D matrix encoding to enhance QR code customization and efficiency, surpassing limitations of traditional black-and-white encoding.
Problem Statement
Traditional QR codes are limited in their customisability and efficiency due to their reliance on black-and-white encoding schemes. This restricts their applicability in scenarios requiring high customisation or efficient data representation. Therefore, there is a need for an alternative encoding method that can address these limitations while maintaining QR code compatibility and readability.
Objectives
Assessing the feasibility of embedding binary pairs within CMYK colour channels.
Investigating the impact of variable error correction mechanisms on QR code robustness and reliability.
Exploring the potential utilisation of Huffman encoding for data compression and optimisation.
Analysing the performance of CMYK-encoded QR codes across various use cases and scenarios.
User Research
Insight: Users generally preferred the CMYK QR code format over black and white, finding it more interesting and satisfying to create. However, they perceived it as an unnecessary distraction in certain contexts and found it difficult to implement into design.
Impact on Users' Lives: Users indicated that QR codes didn't usually have a significant impact on their daily lives. They expressed uncertainty about QR codes and felt inadequately informed on the matter.
Implications for Design: Designers should consider the balance between user preference for CMYK codes and the potential distraction they may pose in certain contexts.

Learnings
Balancing Customization and Accessibility: Striking a balance between offering customizable features, such as CMYK encoding, and ensuring accessibility for all users can be challenging. Designers need to consider how customization options may impact usability and accessibility, especially for users with visual impairments or limitations in colour perception.
Educational Needs: Users expressed uncertainty about QR code usage and felt uninformed about its potential applications. This highlights the importance of providing educational resources and clear guidance to users, helping them understand the benefits and practical uses of QR codes in various contexts.
Contextual Considerations: Users identified certain contexts where CMYK QR codes could be perceived as unnecessary distractions. Designers should consider the context of use and the specific needs of users when implementing customization features, ensuring they enhance rather than detract from the user experience.
Usability Testing and Feedback: Conducting usability testing and gathering feedback from users throughout the design process is essential. It helps identify usability issues, gather insights into user preferences, and iteratively refine the design to better meet user needs and expectations.
Engagement and Satisfaction: Users reported finding CMYK QR codes more interesting and satisfying to create. Designers can leverage this positive sentiment to enhance user engagement and satisfaction by providing opportunities for creative expression and personalization within QR code experiences.
