**Alphanumeric Keyboard**
**A very common,** general purpose**, input device that allows** text **(abc…),**numbers **(123…) and** symbols **(%$@...) to be entered into a computer.**

 **A keyboard is simply a set of buttons. Each button has a symbol assigned.**

 



**Numeric Keypad**
**A small keyboard that only has** numbers**.**

 **Used to enter** numeric data **into computers such as those in ATMs.**

 **Most computer keyboards have a numeric keypad on the right side, and most mobile phones (there are also computers) have a one for entering phone numbers, etc.**

Trackball / Tracker Ball
<span style="display: block; margin-bottom: 0px; margin-left: auto; margin-right: auto; margin-top: 0px; overflow-x: hidden; overflow-y: hidden; padding: 0px; position: relative; width: 760px;"><span style="border: 0px initial initial; display: block; margin-bottom: 10px; margin-left: 0px; margin-right: 0px; margin-top: 0px; overflow-x: visible; overflow-y: visible; padding: 0px; position: relative;"><span style="display: block; float: left; margin-bottom: 10px; margin-left: 0px; margin-right: 0px; margin-top: 0px; overflow-x: visible; overflow-y: visible; padding: 0px; position: relative; width: 488px;">This **pointing** device is not moved about like a mouse, instead it has a**large ball** that the user spins. Data about which direction the ball is spun is passed to the computer.

<span style="display: block; float: left; margin-bottom: 10px; margin-left: 0px; margin-right: 0px; margin-top: 0px; overflow-x: visible; overflow-y: visible; padding: 0px; position: relative; width: 488px;"> It can be used to control a **GUI** pointer.

Touch Screen
<span style="display: block; margin-bottom: 0px; margin-left: auto; margin-right: auto; margin-top: 0px; overflow-x: hidden; overflow-y: hidden; padding: 0px; position: relative; width: 760px;"><span style="border: 0px initial initial; display: block; margin-bottom: 10px; margin-left: 0px; margin-right: 0px; margin-top: 0px; overflow-x: visible; overflow-y: visible; padding: 0px; position: relative;"><span style="display: block; float: left; margin-bottom: 10px; margin-left: 0px; margin-right: 0px; margin-top: 0px; overflow-x: visible; overflow-y: visible; padding: 0px; position: relative; width: 488px;">A touch screen is an alternative to a separate pointing device. With a touch screen the user selects items on the screen by **touching** the surface. This makes touch screen systems very **intuitive** and **simple to use**.

<span style="display: block; float: left; margin-bottom: 10px; margin-left: 0px; margin-right: 0px; margin-top: 0px; overflow-x: visible; overflow-y: visible; padding: 0px; position: relative; width: 488px;"> Often used for **information terminals** in public places e.g. libraries or museums where mice or keyboards may be stolen or damaged.

<span style="display: block; float: left; margin-bottom: 10px; margin-left: 0px; margin-right: 0px; margin-top: 0px; overflow-x: visible; overflow-y: visible; padding: 0px; position: relative; width: 239px;">

<span style="border: 0px initial initial; display: block; margin-bottom: 10px; margin-left: 0px; margin-right: 0px; margin-top: 0px; overflow-x: visible; overflow-y: visible; padding: 0px; position: relative;">

Graphics Tablet
<span style="display: block; margin-bottom: 0px; margin-left: auto; margin-right: auto; margin-top: 0px; overflow-x: hidden; overflow-y: hidden; padding: 0px; position: relative; width: 760px;"><span style="border: 0px initial initial; display: block; margin-bottom: 10px; margin-left: 0px; margin-right: 0px; margin-top: 0px; overflow-x: visible; overflow-y: visible; padding: 0px; position: relative;"><span style="display: block; float: left; margin-bottom: 0px; margin-left: auto; margin-right: auto; margin-top: 0px; overflow-x: hidden; overflow-y: hidden; padding: 0px; position: relative; width: 488px;"><span style="border: 0px initial initial; display: block; margin-bottom: 10px; margin-left: 0px; margin-right: 0px; margin-top: 0px; overflow-x: visible; overflow-y: visible; padding: 0px; position: relative;">A **pointing** device often used by **designers** and **artists** to allow **natural hand movements** to be input to **graphics** applications. <span style="display: block; float: left; margin-bottom: 10px; margin-left: 0px; margin-right: 0px; margin-top: 0px; overflow-x: visible; overflow-y: visible; padding: 0px; position: relative; width: 239px;">A stylus is held like a pen and moved over the surface of the tablet. Data about the stylus movements are sent to the computer.

<span style="display: block; float: left; margin-bottom: 10px; margin-left: 0px; margin-right: 0px; margin-top: 0px; overflow-x: visible; overflow-y: visible; padding: 0px; position: relative; width: 239px;"> Since it is so like using a pen, it is very easy to create ‘**hand-drawn**’ sketches.

<span style="display: block; float: right; margin-bottom: 10px; margin-left: 0px; margin-right: 0px; margin-top: 0px; overflow-x: visible; overflow-y: visible; padding: 0px; position: relative; width: 239px;">
