What is meant by good user interface? Explain its importance.
Answer
A good user interface is one that is intuitive, efficient, and reliable, allowing users to achieve their goals with minimal cognitive load and error. It bridges the gap between human intent and machine execution through clear communication and predictable behavior. Its importance lies in increasing user productivity, reducing training costs, minimizing errors, and improving overall user satisfaction and system adoption rates.
Explain about the important human characteristics in design.
Answer
Important human characteristics in design include perception, which involves how users interpret visual and auditory stimuli; memory, specifically the limitations of short-term and working memory; attention, which is selective and finite; and motor skills, which dictate the speed and accuracy of physical interaction. Understanding these cognitive and physical constraints ensures that interfaces are designed to match human capabilities rather than forcing users to adapt to rigid system requirements.
