At present, a mobile terminal can detect heartbeat through infrared sensing arranged on the terminal. However, errors easily occur in detection through the infrared sensor, and the terminal cannot provide heartbeat detection for the user through other modes.
The embodiment of the application provides a heartbeat detection method, which can acquire periodic pressure waves representing heartbeats through a pressure sensor arranged on the side of a terminal, determine heartbeat information based on the periodic pressure waves, further detect the heartbeats of a user through pulse pressure and improve the accuracy of heartbeat detection. The specific scheme is as follows:
fig. 1 is a schematic flow diagram of a heartbeat detection method according to an embodiment of the present application, where the method is used in a situation where a terminal is held by a single hand to perform heartbeat detection, and the method may be executed by a mobile terminal, where the mobile terminal may be a smart phone, a tablet computer, a wearable device, a notebook computer, and the like, and the method specifically includes the following steps:
and step 110, when a starting instruction is received, acquiring side pressure information according to a preset time interval.
The terminal is composed of two long sides and two short sides. Pressure sensors may be provided on the two long sides, respectively. The contact of the pressure sensor may be located in the middle of the long side, the length of the contact being one third of the length of the long side. The pressure sensors may also be located in the third of the two ends of the long side. Because the user is when single-handed holding, the bottom of holding the terminal usually, set up pressure sensor's contact can more convenient detection pressure in the bottom. A plurality of contacts may be provided on the long side, each of which transmits the detected variable information to the pressure sensor. The pressure sensor may employ at least one of a piezoresistive force sensor, a ceramic pressure sensor, a diffused silicon pressure sensor, or a piezoelectric pressure sensor.
The pressure sensor comprises a pressure sensitive component and a processing component, the pressure sensitive component is connected with the contact, and the processing component determines a pressure value according to a variable signal acquired by the pressure sensitive component. The side pressure information may include the pressure value, and may also include out-point information corresponding to the pressure value, that is, a position where the user applies pressure, so as to obtain different pressure values detected by the plurality of contacts on the side.
Further, the user may initiate to perform step 110 by performing a preset terminal operation. For example, the user tilts the terminal while holding it with one hand. The terminal can be detected to be in a tilting state through the gyroscope. At this point, if the user presses the pressure sensor contact on the side of the terminal with the hand holding the terminal, execution of step 110 may be triggered.
Optionally, the user starts a pulse pressure detection function of a preset application program (APP), and when the user clicks a detection button in the function, step 110 is executed.

A computer readable signal medium may also be any computer readable medium that is not a computer readable storage medium and that can communicate, propagate, or transport a program for use by or in connection with an instruction execution system, apparatus, or device.
Program code embodied on a computer readable medium may be transmitted using any appropriate medium, including but not limited to wireless, wireline, optical fiber cable, RF, etc., or any suitable combination of the foregoing.
Computer program code for carrying out operations for aspects of the present application may be written in any combination of one or more programming languages, including an object oriented programming language such as Java, Smalltalk, C + +, or the like, as well as conventional procedural programming languages, such as the "C" programming language or similar programming languages. The program code may execute entirely on the user's computer, partly on the user's computer, as a stand-alone software package, partly on the user's computer and partly on a remote computer or entirely on the remote computer or server. In the case of a remote computer, the remote computer may be connected to the user's computer through any type of network, including a Local Area Network (LAN) or a Wide Area Network (WAN), or the connection may be made to an external computer (for example, through the Internet using an Internet service provider).
Of course, the storage medium provided in the embodiments of the present application and containing the computer-executable instructions is not limited to the above-described heartbeat detection operation, and may also perform related operations in the heartbeat detection method provided in any embodiments of the present application.
