Abstract
The invention discloses a touch sensing method and a portable electronic apparatus. The portable electronic apparatus includes a capacitive touch sensor unit, an acoustic touch sensor unit and a processing unit. The capacitive touch sensor unit and the acoustic touch sensor unit are used for monitoring a touch input interface. When both of the capacitive touch sensor unit and the acoustic touch sensor unit sense a touch input on the touch input interface at the same time and in response generate a first sensed coordinate and a second sensed coordinate respectively, the processing unit selects or executes an application function on the touch input interface according to the first sensed coordinate.
