Touch screen technologies used in cell phones embrace resistive, capacitive and floor-wave based systems. A draw back is that after the initial touch, the system can not detect a immobile finger.

The digitized signal is compared to a list corresponding to every place on the floor, determining the touch location.
When a user touches the monitor with his finger, some of the charge is transferred to the consumer, so the cost on the capacitive layer decreases. That is what helped breed the touchscreen monitor market, which has many viable choices for people searching for the perfect of both worlds.
