käyttöliittymämenetelmä

Käyttöliittymämenetelmä, often abbreviated as ULM, is a design approach used in human-computer interaction to create intuitive and efficient interfaces. It focuses on the user's needs and tasks, aiming to minimize the cognitive load required to interact with a system. The method involves several key principles:

Firstly, ULM emphasizes the importance of understanding the user and their context. This includes analyzing user needs, tasks, and goals to inform the design process. Secondly, it advocates for iterative design, where prototypes are created and tested with users, with feedback incorporated into subsequent iterations.

A central aspect of ULM is the use of direct manipulation, allowing users to interact with objects on the screen in a way that mimics real-world actions. This can enhance usability and user satisfaction. Additionally, ULM promotes consistency in design, ensuring that similar tasks are performed in similar ways across the interface.

Another key principle is the use of affordances, which are visual cues that suggest how an object can be used. For example, a button that looks like it can be pressed is an affordance. ULM also encourages the use of feedback, providing users with clear and immediate information about the results of their actions.

Lastly, ULM considers the overall user experience, including factors like aesthetics, accessibility, and learnability. The goal is to create interfaces that are not only functional but also enjoyable and satisfying to use.

ULM was popularized by Ben Shneiderman and his colleagues at the University of Maryland, and it has been influential in the field of human-computer interaction. However, it is important to note that ULM is just one of many design approaches, and its principles may be adapted or combined with others to suit specific design challenges.
