TVI, or Television Interference, refers to disruptions in the quality of television signals. This can occur due to various factors, including physical obstructions, electronic devices, or atmospheric conditions. When TVI happens, viewers may experience poor picture quality, sound issues, or complete signal loss. Another context for TVI is Total Visual Impairment, a condition where individuals cannot see or have very limited vision. This can significantly impact daily activities and requires adaptations for communication and mobility. Support services and assistive technologies are often utilized to help those with TVI navigate their environments effectively.
