Multimodal Alert System
Also known as: Multi-Sensory Alert, Multimodal Notification
A notification system that communicates alerts through multiple sensory channels simultaneously, such as combining audio, visual, and haptic signals. Multimodal alert systems are critical for accessibility because they ensure people with different sensory abilities can perceive important information. For example, a doorbell that flashes lights, plays a sound, and sends a mobile notification serves deaf, blind, and hearing users alike.
