Human – Computer Interaction
Human – Computer Interaction (HCI) is a part of interest aiming on the design of computer technology, particularly, the interaction between humans/users and computers. And it expanded to cover almost all systems of computer technology design. And from the past years we are using the same techniques on how to interact with the machines by using mechanical devices like mouse and keyboard. Some studies on technology focuses on how to communicate with the machines naturally. Since there are some difficulties in using the mouse and keyboard as input devices, researchers think of more convenient way to how to communicate to machines without any mechanical devices or wires connected to your body. Gesture recognition was developed.
