Definition: A HCI is the term for using an input device to enable a video game to work.
THe typical HCI that everyone in gaming knows is the controller.wiether you are a pc gamer, mobile gamer, or any other type you have used a HCI.
Mouse
the mouse is one of the most common HCI's as it is one of the simplists uses in gaming.the reason behind this is its multiple uses both in and out of gaming . the uses include pure useage for googleing and photo editing to hardcore gamings.
keyboard
the keyboard is also a very popular HCI.one that allows the user tyo do many things including binding keys to do specific functions to just typeing leters and number which use the base functions of searching,coding writing essays and much much more.
controller
the controller is the 3rd of three most common HCI's and is the most complex an the way that it is a mix of both the keyboard and mouse on a much smaller scale.in this way the joysticks and dpad's work as a simple mouse moving the cursor or reticle round the screen .while this is going on the controllers buttons simultaneously are pressed to use some of the same functions as a keyboard specifically in terms of gaming as you cant fit a full keyboard onto a small controller.
touch
touch screen devices including most modern handhelds have the simple but effective use of your finger as the control system this includes using a pop up keyboard for the purpose of typing numbers and letters.the touch screen also allows for some interesting ways of control such as swiping and pinching these do the effects of the scroll wheel and the resize tool in certain programs.
other controllers
these three types of other HCI's are a long list of odd and wonderful controllers as they decided to change the way a game is played either the way its viewed or the way the controller works the way that certain controllers allow the user to controller the character however all of them have buttons even if it is a HCI that is used in tangent with a controller of some kind
user centred design is where the design of a HCI is created for the use of functions and needs of consoles and other hardware.this means that they will choose where to place buttons very carefully so that nobody has a problem reaching them.after this they will send the speciphications of to be deigned
