Capacitive sensing knob or slider apparatus and touch sensitive apparatus thereof and touch system

Abstract

A detecting method of an input apparatus, wherein the input apparatus including an input electrode, a driving electrode, and multiple sensing electrodes which are not in contact with others, a part of the input electrode simultaneously covering the driving electrode and one or two sensing electrodes, wherein the detecting method comprising: transmitting driving signals from the driving electrode; simultaneously sensing the induced driving signals via the sensing electrodes to get multiple signal strength values, respectively; and determining a position of the part with respect to the multiple sensing electrodes according to the signal strength values.
