Embodiment Construction
[0043] As described in the Background Art, when the periodic light intensity of the electronic device in the prior art is weak, it is difficult for the operator to accurately identify the exact direct operation position, and the probability of misoperation is high, which affects the user experience.
[0044] In view of this, an embodiment of the present invention provides an information processing method, which is applied to an electronic device, where the electronic device includes: an ultrasonic transmitter, a speaker, and at least one microphone; the method includes:
[0045] controlling the ultrasonic transmitter of the electronic device to transmit ultrasonic waves into the first space on the side of the first surface of the electronic device by using the speaker of the electronic device, so that a collection area is formed in the first space;
[0046] Obtain a feedback signal of the ultrasonic wave through at least one microphone of the electronic device, where the feedba...

Embodiments of the present invention disclose an information processing method and an electronic device. The electronic device comprises: an ultrasonic transmitter, a speaker, and at least a microphone. The method comprises: transmitting, by the ultrasonic transmitter that controls the electronic device, an ultrasonic wave to a first space at one side of a first surface of the electronic device by using the speaker, so as to form a collection area in the first space; obtaining a feedback signal of the ultrasonic wave by using the at least one microphone of the electronic device; processing a feedback signal obtained in each of the at least one microphone, so as to determine an input operation of an operating body in the collection area; and generating a control instruction corresponding to the input operation based on the input operation. According to the method, the control instruction is responded, so that the input operation of the operating body can be recognized while a user does not need to directly contact the electronic device. A requirement on surrounding light intensity is relatively lower, so that a probability of erroneous operation when the surrounding light intensity of the electronic device is relatively low is reduced, and user experience is improved.
Description
technical field [0001] The present invention relates to the technical field of information processing, and in particular, to an information processing method and an electronic device. Background technique [0002] At present, the operation methods of electronic equipment are mainly buttons and touch. No matter which operation method is adopted, both the operating body and the electronic equipment are required to be in direct contact, and only the direct contact at the designated position can be operated accurately, so that the electronic equipment can be operated accurately. It has high requirements on the surrounding light intensity. When the periodic light intensity is weak, it is difficult for the operator to accurately identify the exact direct operation position, and the probability of misoperation is high, which affects the user experience. SUMMARY OF THE INVENTION [0003] In order to solve the above technical problems, embodiments of the present invention provide ...
