“In a properly automated and educated world, machines may prove to be the true humanizing influence. It may be that machines will do the work that makes life possible and that human beings will do all the other things that make life pleasant and worthwhile.” 

American writer and professor Isaac Asimov’s quote from his book Robot Visions’, first published three decades ago, could very well have been an apt prediction for the technologically advanced world we live in today.

There’s no escaping the fact that machines and automation have become an indispensable part of human lives today.  All forms of technology usually require an interface to establish a sync between humans and machines and input-output devices help achieve precisely this, bridging that gap. 

Input devices – the common link that transforms an instruction from an end-user to an output processed by a machine sent back to the user – are omnipresent and integral to our daily lives. Input devices are used in many industries – from consumer electronics to industrial equipment, from medical and healthcare to defence and aviation. 

Here’s a rundown of the applications of the most commonly used input devices.
