An electronic apparatus and a method for switching touch modes thereof are provided. A touch screen of the electronic apparatus has a plurality of touch modes. A current touch mode of the touch screen is one of the plurality of touch modes. The method includes the following steps. Firstly, the number of times a key module of the electronic apparatus is pressed is determined according to a pulse count of a trigger signal provided by the key module. Next, a first touch mode of the plurality of touch modes is looked up in a lookup table according to the number of times. Afterwards, the current touch mode of the touch screen is switched to the first touch mode.

Electronic apparatus and method for switching touch mode thereof

An object detection method using ultrasonic waves includes: emitting a plurality of ultrasonic signals sequentially according to a time interval; sensing a sound wave formed by each of the ultrasonic signals to generate a reflected signal; and analyzing the reflected signal to detect at least one reflection object. It can be clearly known whether a reflection object is appearing, moving and the moving direction by the method.
