Embodiment Construction

[0087] The specific implementation manners of the present invention will be described in further detail below in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0088] When the human eye looks at the target object, the process of clearly imaging the object on the retina can be called the focus of the eye. Correspondingly, the point with the clearest image on the retina is the focus point of the human eye when viewing the target object.

[0089] Such as figure 1 As shown, the embodiment of the present invention provides a reminder method, which includes the steps of:

[0090] S110. Detect the focus point position of the user's line of sight;

[0091] S120. Remind the user according to the focus point position and the user status.

[0092] The method of the embodiment of the present invention can provide a more accurate reminder bas...

Abstract

The invention discloses a reminding method and device, and relates to the technical field of intelligent reminding. The method comprises the steps of detecting the focusing point position of sight of a user, and reminding the user according to the focusing point position and the user state. According to the method and device, the focusing point position of the sight of the user can be precisely detected, the user is precisely reminded according to the focusing point position, and the suitable range is wider. In addition, according to the user state, the user resources and the like, monitoring parameters are selected, a reminding threshold value is set, and suitable reminding can be carried out on the user in a more-targeted mode.

Description

technical field [0001] The invention relates to the technical field of intelligent reminders, in particular to a reminder method and device. Background technique [0002] According to research, in addition to age and genetic reasons, unhealthy or even incorrect eye use is the main reason for people's vision loss. For example, long-term, close-up eye use, etc. In addition to vision loss, in some scenarios, incorrect eye use may cause serious consequences. For example, in the driving state, if the driver loses focus for a long time and looks at the wrong direction, it may cause traffic accidents and pose a great threat to personal safety. [0003] In order to protect eyesight and supervise the correct use of eyes, there is a method of using infrared distance measurement to measure the distance between the eyes and the object in front of the user, and then reminding when the distance is inappropriate. This method can provide a good reminder to the user in certain application...
