The normal way that a computer functions manually is through a person that controls the computer. An individual generates computer actions with the use of either a computer mouse or keyboard. However the latest technology and computer innovation might allow a computer to not only detect body language but also respond to it. Modern devices are being experimented with, that may potentially allow that computer related device to respond to and understand an individual's hand gesture, specific movement or facial expression.

In relation to computers and body language, research is being done with the use of mathematics in order to teach computers to interpret human movements, hand gestures and even facial expressions. This is different from the normal way people generally communicate with computers for example with the click of the mouse, keyboard, or any physical contact in general between the user and the computer.
