Human-computer interaction (HCI) is the study and design of how people engage with digital technologies, aiming to create systems that are intuitive, efficient, and responsive to users' needs.
In recent years, HCI has played a critical role in advancing accessibility, developing adaptive interfaces, voice controls, and assistive devices that empower individuals with disabilities to access information, communicate, and navigate digital environments more easily. In healthcare, HCI supports the design of patient-centered technologies such as telemedicine platforms, electronic health records, and wearable health monitors, enhancing both clinical outcomes and patient experiences.
Emerging work also explores how interactive systems, including virtual agents and AI-driven applications, can support mental health, chronic disease management, and rehabilitation. As digital systems become more embedded in everyday life, HCI continues to prioritize inclusivity, usability, and ethical design.
