A touch screen allows user commands to be issued by pressing matching buttons on the screen. Chances are, if you have used an automated teller machine, owned a personal digital assistant, or played with the newer cell phones, you have already used touch screen technology. There are several commonly used systems that allow for touch screens to work. Each method allows for commands to be translated by the computer as a result of touching a certain point on the screen. Many convert the coordinates of the touch locations to specific actions to be taken by the system.
Graphics Tablet
A graphics tablet is an input device used by artists which allows one to draw a picture onto a computer screen without having to utilize a mouse or keyboard. A graphics tablet consists of a flat tablet and some sort of drawing device, usually either a pen or stylus. A graphics tablet may also be referred to as a drawing tablet or drawing pad. While the graphics tablet is most suited for artists and those who want the natural feel of a pen-like object to manipulate the cursor on their screen, non-artists may find them useful as well. The smooth flow of a graphics tablet can be refreshing for those who find the mouse to be a jerky input device, and repetitive stress injuries such as carpal tunnel syndrome are less likely when using a graphics tablet.
Games controller
Wireless and wire game controllers are handheld controllers for gaming consoles that can have cord or no cord. Wireless game controllers use wireless technology to enable game play to be less restrictive, allowing players to sit virtually anywhere in the room. They are available for all major gaming consoles and computers. If you’ve ever sat down to play a video game on a home console, and then you understand the meaning of restricted movement. Traditional game controllers plug into ports on the console, and the player or players can position themselves only as far from the console as the wires on the controller will reach. This problem can greatly reduce the comfort level of a player settling down for the long haul, especially if the couch is too far away from the TV.
Microphone
A USB microphone is a microphone that is designed for use in a personal computer or laptop and utilizes the “plug and play” technology that is associated with USB ports. Devices that use USB technology are popular since all someone needs to do to use it is plug it into the USB port, after which the device is quickly powered up and running.
Mouse
A mouse is a pointing device that functions by detecting two-dimensional motion relative to its supporting surface. Physically, a mouse consists of an object held under one of the user's hands, with one or more buttons. It sometimes features other elements, such as "wheels", which allow the user to perform various system-dependent operations, or extra buttons or features that can add more control or dimensional input. The mouse's motion typically translates into the motion of a cursor on a display, which allows for fine control of a graphical user interface.
Keyboard
A keyboard is a type writer-style which uses an arrangement of buttons or keys, to act as mechanical levers or electronic switches. Following the decline of punch cards and paper tape, interaction via teleprompter-style keyboards became the main input device for computers.
