smart board activities for pre k.?Projected capacitive touch screens, which are widely used in portable devices today, are susceptible to electromagnetic interference, and interference voltages from internal or external sources are capacitively coupled to the touch screen device. These interfering voltages can cause charge movement within the touch screen, which can be confusing for the measurement of charge motion when the finger touches the screen. Therefore, the effective design and optimization of the touch screen system depends on the knowledge of the interference coupling path and the reduction or compensation as much as possible. Interference coupling paths involve parasitic effects such as transformer winding capacitance and finger-to-device capacitance. Proper modeling of these effects can fully understand the source and size of the interference.
