They are: Capacitive and Resistive.
Capacitive screens detect a single point of contact between two layers when they are pressed together.
Resistive screens detect electric fields (such as the one in a human body) coming into contact with the electircal current passing through the screen.
Why might you be interested?
- Resistive screens work best when used with a stylus.
- Capacitive screens work with a finger.
- Capacitive screens don't have to have contact made to detect input.
- Capacitive screens are commonly acknolwedged to be easier to use and more intuitive.
- Windows Mobile only officially supports resistive screens. While there have been examples of Windows Mobile running on a device with a capacitive screen, such devices are not available and are unlikely to be so in the foreseeable future.
Finger frustration, not finger fun!
