How Multimodal User Interface will redefine customer experience

A Multimodal User Interface (MUI) is a revolutionary system that transforms our daily interactions with technology. Imagine managing your home gadgets with voice commands while adjusting settings on a display screen with touch controls.

This is the practical power of MUIs, making our lives easier and more intuitive.

From birth, we learn to interact with the world and others with our senses.

Almost all human beings know and are able to express their intent for various actions. But, with technology, one must learn how to use it.

So, it's only natural that we should be able to interact with technology in a way that feels natural. Humans are at their best while speaking, making gestures with their hands, and can smell and hear with their noses and ears.   

Now, everyone realizes that humans should be allowed to carry out various activities naturally.

For example, why type for an email? Why can't one converse with another person just by talking? MUIs bring this naturalness to technology, making interactions comfortable and intuitive.

Though a little far away, imagine the ability to smell the aroma of food while reading the menu in a restaurant or the ability to feel the crisp air while checking about a hill station on your laptop ( though I am not sure, by that time, whether laptops and food menus will be relevant or will be replaced by something else).

This is the future of user interaction, and it's here with MUIs.

The technology underpinning Multimodal User Interfaces combines state-of-the-art elements:

 1. Natural Language Processing (NLP) empowers devices to comprehend and interpret language, enabling voice commands and conversational interfaces

OTOH, when you say "type an email", they ask "Why can't one converse with another person just by talking?" 

OTOrH, when you say "converse by talking", they say "This call could have been an email".

I wonder if there's anything "natural" about human behavior.
