A touch screen Information kiosk enables interactivity via a specialized type of digital display that responds to pressure or placement of certain types of objects on the screen, such as a finger, or a stylus.

Touchscreens work using electricity. The screen is made of glass, an insulating material – it cannot carry an electric current. The surface of the screen is therefore coated with a thin layer of an electrically conducting material such as indium tin oxide. This is chosen because it is transparent.

There are 3 types of touchscreens:
1-Resistive Touchscreen.
2-Surface Acoustic Wave Touchscreen. &
3-Capacitive.

Use of Kiosk:

Kiosks are small, temporary booths placed in areas with high foot traffic that are used by businesses to reach their customers in a more simple and informal manner. Kiosks are primarily used for marketing purposes and can be staffed by individuals or self-service.

digital kiosks used in include:

Healthcare: Self-check-in kiosks at doctors’ offices; prescription pickup and payment kiosks at pharmacies

Restaurants: Self-ordering kiosks or interactive seating kiosks for front-of-house staff

Retail: Point-of-sale systems or self-checkout kiosks

Transportation: Check-in and ticketing kiosks at airports or train stations

Parking: Payment kiosks for parking structures

Directories: Large touch screen digital signage kiosks for store directories and advertising in shopping centers

Kiosks don’t have to be fixed to a permanent location, either. For example, admissions at a hospital may have a kiosk on wheels to roll around through the emergency room to get people checked in.
