Jargon
phantom touch 鬼手
mist-covered screen 屏幕起雾
Look-for-Touch,查找触摸模式
Look-for-touch is a low-power and fast-wakeup mode, in which the touchscreen sensor is measured for an increase in self capacitance. An increase in self capacitance indicates that a touch is present. Because it is only necessary to detect a finger’s presence, and not location, the sensing can be done at a much lower SNR, requiring less time and power. Look-for-touch sensing is used to implement multiple functions, including wake-on-touch and fast first-touch response.
