Multimodal

Relating to communication or interaction that uses multiple sensory channels or modes simultaneously, such as vision, hearing, touch, and speech. In accessibility, multimodal approaches are essential for making information available to people who cannot access one or more sensory channels. For example, graphical web content can be made accessible to blind users through a combination of text descriptions (for screen readers), spatialized audio (sonification), and haptic feedback (tactile output via force-feedback devices or refreshable braille displays). Multimodal representations often provide a richer understanding than any single modality alone.
