Resource summary

Input Devices
1 Concept keyboard
1.1 Each button on a concept keyboard relates to a particular item or function. Buttons can be labelled with text or a picture. Fast food restaurants often use concept keyboards because very little training is needed to operate them and they're efficient - a single button can order an entire meal
2 Trackball
2.1 Used as an alternative to a mouse. To operate it the user rotates the ball which moves the pointer on screen. They are particularly easy to use for those with limited movement in their hands
3 Joystick
3.1 Joysticks used to be popular with gamers but have slowly been replaced by other types of game controller. In construction, joysticks are used to control machinery such as cranes.
4 Digital camera
4.1 A digital camera takes pictures and can usually record video too. The pictures it takes and the videos it records are stored in files.
5 Microphone
5.1 Microphones are used to input sound. In computing they can be used with voice recognition software and a word processing application to enter text. Webcams commonly have microphones built-in too.
6 Scanner
6.1 A scanner can be used to digitise images. They're similar to a photocopier but they make a digital copy instead of a physical copy.
