A common feature of human-computer interaction (HCI) is the focus on designing interfaces that prioritize user experience and usability. HCI studies the interactions between humans and computers, aiming to improve the ease with which users can operate digital systems. Principles such as usability, accessibility, and user-centered design are foundational. Effective HCI design leads to more efficient, satisfying interactions, ultimately resulting in better adoption rates and overall user satisfaction in software applications and systems.
