A smartwatch and, a method for controlling the smartwatch, where a plurality of capacitive touch sensors is disposed around a screen of the smartwatch. The method includes obtaining a calibrated capacitance value of each capacitive touch sensor, determining a quantity of touch points based on maximum values of calibrated capacitance values of the N capacitive touch sensors, where each touch point corresponds to one capacitive touch sensor, determining a location of each touch point based on a calibrated capacitance value of a capacitive touch sensor corresponding to the touch point and a calibrated capacitance value of a capacitive touch sensor neighboring to the capacitive touch sensor, and executing a control instruction matching the quantity of touch points and the location of each touch point.
