Skin Screen
Why can I only use my skin on touch screen phones?
Why doesn't, for example, a pencil eraser work on touch screens? just wondering. thanks.
Touch screen is sensitive to the moisture and electric charge from your skin. The moisture on your skin carries small electrical pulses from your body to the screen, these pulses are picked up by sensors allowing the processor to identify where your finger is. In short...if it can't transmit a small charge to the screen it won't work.
