HTC Patents Stylus for Capacitive Screens

HTC has patented a new type of stylus that can interact with capacitive touch screens. Styli have long been used by mobile phones with resistive touch screens (which respond to physical pressure), and are highly accurate. Normal styli don't work with capacitive touch screens because capacitive screens interact with the electrical disturbance created by the human finger. HTC's patent adds a magnetic head to the tip of a stylus, which allows it to activate and interact with a capacitive touch screen. Such a device will give users a much greater degree of control and accuracy. This is particularly important for phones used in Asian markets.
