Embodiment 1
[0026] figure 1 It shows a flow chart of an alarm method based on a smart terminal provided in Embodiment 1 of the present application, and the method includes:
[0027] Step S110: Obtain iris characteristic information of the user, and compare the iris characteristic information with preset user characteristic information.
[0028] In a specific implementation, the iris feature information can be obtained through the iris camera, or the user's iris feature information can be obtained in other ways. The purpose of iris feature information is enough.
[0029] Wherein, the preset user feature information is the iris feature information of the terminal owner, which is used to identify whether the user triggering the alarm operation is the owner of the terminal, so as to avoid false triggering or malicious triggering by others.
[0030] Step S120: When the iris feature information matches the preset user feature information, compare the acquired user's eye movement information w...
Embodiment 2
[0039] figure 2 It shows a flowchart of an alarm method based on a smart terminal provided in Embodiment 2 of the present application, and the method includes:
[0040] Step S210: Continuously monitor whether the user's eye state matches the preset user state information, and when the monitored user's eye state matches the user state information, perform step S220.
[0041] Wherein, this step is an optional step, and its function is to determine when to start implementing the alarm method, so as to avoid implementing the alarm method due to mistakes in normal use. Specifically, in this embodiment, it is judged whether to implement the subsequent alarm method by continuously monitoring the user's eye state. In this step, the preset user state information refers to a certain eye state of the user, and this state is also It is the trigger condition, which can be a static state, such as when the user looks at a certain position of the smart terminal for a preset specific length ...
Embodiment 3
[0062] image 3 A schematic structural diagram of an alarm device based on a smart terminal provided in Embodiment 3 of the present application is shown, and the device includes:
[0063] The user information obtaining unit 31 is configured to obtain iris characteristic information of the user and eye movement information of the user.
[0064] In a specific implementation, the iris feature image of the user may be acquired through the iris camera, and iris feature information may be extracted from the image through an iris algorithm, or the user's iris feature information may be acquired in other ways. In order to improve the clarity of the iris image, an iris camera dedicated to taking iris images can be further installed inside the smart terminal. The iris camera can accurately identify the user's iris information, thereby improving the accuracy of subsequent recognition. The user's eye movement information can also be extracted from the above-mentioned iris feature image t...
