Multimodal refers to the integration and use of multiple modes or forms of communication, such as text, images, sounds, gestures, and touch, in order to convey information or facilitate interaction. It involves combining different sensory channels simultaneously or sequentially to enhance the overall user experience.

Multimodal interfaces or systems enable users to communicate or access information through various modalities, accommodating different preferences, abilities, and contexts. By leveraging multiple modes of communication and interaction, multimodal interfaces can improve accessibility, efficiency, and usability in various domains, including human-computer interaction, user interfaces, and assistive technologies.
