Do I have to use my finger or can I use another pointing device with a touch screen?
This depends on the type of touch screen.
- Resistive touch screens are pressure sensitive and will work with any type of input- finger, gloved hand, stylus, pen, or any pointing device.
- Capacitive touch screens will only work with finger input.
- SAW (surface acoustic wave) touch screens will work with finger input or soft-tipped stylus input. A SAW touch screen will not work with a hard tipped pen, but a soft-tip stylus will work.
- Infrared touch screens will work with any type of input- finger, gloved hand, stylus, pen, or any pointing device. However, if a stylus or pen is used, in most cases it is recommended that the tip touching the screen should have a diameter of at least 4mm.
