Touchscreens

Use
Resolution
Another important factor here is choosing the correct controller board, whether
8 Bit = 256x256,
10 Bit = 1024 x 1024, or
12Bit = 4096x4096
depending on the size of the touchscreen.
Transparency (transmission)
Life expectancy
Resistance to vandalism
Reaction time
Sensitivity to interference (EMC)
Soiling and insulation
Operability using a finger, glove or stylus
The cost

Low costs: changes to the software can be used to quickly alter the device type, image or language
User-friendly
No complicated use of keys or a mouse, thereby reducing the number of errors made
Extremely useful for applications in which weight plays an important role, e.g. in portable devices

Notebooks, hand-held computers
Corporate data entry systems
Machines and process control
Medical devices e.g. for monitoring patients or X-ray machines
Access control systems
Laboratory and analytical devices
Cash dispensers
Kiosk systems
Copying systems
