10. Touch sensitive interface

Touch sensitive interfaces can be found on many mobile devices such as a smart phone or a tablet computer.

They work by your finger touching the screen. The touching is detected and translated by the device into instructions. As well as tapping, the screen can sense swiping and pinching actions.

Many Cashpoint machines (ATMs) have touch sensitive screens where you can use your finger to select a service such as withdrawing cash, seeing your balance or ordering a statement.

Ticket ordering systems in train and bus stations also use touch sensitive interfaces. You select your journey from a menu of options, select the date and time and then indicate how you are going to pay for the ticket.

Museums and art galleries often have touch sensitive screens where you can find out more information about a particular display or piece of art by selecting a graphic icon.

Updated operating systems such as Windows 8 now have built-in touch capability.
