Improving the User Experience of Smart Locks : A Study on Implementing Inclusive Design on Keypads

Sammanfattning

As smart locks become increasingly more common, the need for inclusive and accessible keypad design grows. This thesis investigates how keypad interfaces can be designed to accommodate a diverse range of users, including individuals with varying physical, sensory, and cognitive abilities. The project was conducted on behalf of a company specializing in locks and access systems, the project follows the Double Diamond design process—Discover, Define, Develop, and Deliver. Through a combination of literature review, user testing, interviews, and evaluations, the study identifies common usability challenges such as unclear symbols, poor visibility, and insufficient tactile feedback. These insights informed a set of design recommendations, compiled into a handbook and applied to two conceptual product prototypes. The results emphasize the importance of intuitive layouts, clear visual and tactile cues, and responsive feedback. By addressing these aspects, the proposed solutions aim to enhance usability for a broader user base and support the development of more inclusive products.
