Building upon her foundational work, Kevin Silver expanded this framework by adding a fifth dimension, creating a robust model that encapsulates the essential components required for successful user interface designs.
1D: Words
Words serve as a direct communication tool in interaction design. Effective text on user interfaces, such as labels on buttons or instructions, should be clear and concise. The aim is to communicate with users in a straightforward manner without overwhelming them with excessive information. Properly chosen words help ensure that users understand their options and the actions they are taking.
2D: Visual Representations
While words convey direct messages, visual representations enhance understanding and engagement. This dimension includes elements like typography, icons, images, and other graphical components. These visuals work in tandem with text to deliver rich, context-enhanced interactions that are memorable and easy to navigate, greatly enriching the user experience.
3D: Physical Objects or Space
Interaction design often extends into the physical space that users inhabit, involving elements like the devices they interact with (e.g., computers, mobile phones) and the physical context surrounding these interactions (e.g., an office setting or mobile use on-the-go). The design and arrangement of these physical objects can significantly affect the usability and comfort of user interactions.
4D: Time
Time plays a crucial role in how users perceive the behavior of an interface. It includes the dynamics of animations, the response time after a user takes an action, and the progression through a digital experience. Proper management of time ensures that users remain engaged and can track changes within the interface effectively, enhancing their overall experience and understanding of the system’s performance.
5D: Behavior
Behavior encompasses the interactions between the user and the system—how users act and how the system responds. This dimension is about creating an intuitive flow that users can follow effortlessly. It involves designing interactions that are predictable yet flexible, allowing users to feel in control. Behavior shapes not only how a user interacts with a system but also how those interactions influence future behavior and user expectations.
Conclusion
The five-dimensional model proposed by Gillian Crampton Smith and expanded by Kevin Silver provides a comprehensive framework for understanding and implementing effective interaction design. By considering these dimensions—words, visual representations, physical space, time, and behavior—designers can create more intuitive, engaging, and successful user interfaces that resonate well with the needs and expectations of users.
