Webcam-Based Interaction

An interaction paradigm where users communicate with a computer system through a webcam or camera, using gestures, sign language, facial expressions, or body movements as input. In accessibility contexts, webcam-based interaction enables alternative input methods for people who cannot use traditional keyboard and mouse interfaces, and powers sign language recognition tools that allow deaf users to interact with technology in their preferred language. Key design considerations include video recording quality guidance, real-time feedback, latency management, and privacy concerns about camera usage and video data storage.
