Problems solved by technology

When reading with their heads down, the chances of the holders of these handheld terminals to look up and look at the surrounding conditions are greatly reduced. Moreover, users tend to be immersed in the reading content and ignore the surrounding dangers, such as when walking, encountering people or things around them. Collision, or when encountering theft, the reaction is not timely, etc.

Embodiment 1

[0052] The flow chart of the obstacle warning method disclosed in the embodiment of the present invention is as follows: figure 1 As shown, the method is applied to a handheld terminal. Specifically, the method includes the following steps:

[0053] Step S101: Obtain obstacle information around the handheld terminal in real time, the obstacle information at least including the actual relative distance between the obstacle and the handheld terminal;

[0054] It should be noted that there are many ways to obtain information about obstacles around the handheld terminal, and various ranging sensors, cameras, or radar detection devices can be used. In this embodiment, only the radar detection device is used to detect obstacles around the handheld terminal in real time. The obstacle information is described as an example. In this embodiment, it is preferably an infrared or Bluetooth radar detection device, and the radar detection device can be externally installed or embedded in the...

Embodiment 2

[0075] The flow chart of the obstacle warning method disclosed in this embodiment is as follows: Figure 5 As shown, the difference between the method in this embodiment and the previous embodiment is that the way of warning and prompting the dangerous situation of the obstacle is embodied, as in step S204: according to the preset distance between the obstacle and the handheld terminal, According to the corresponding relationship between the level of the relative distance and the alarm mode, the alarm mode corresponding to the estimated relative distance level at the next moment is used to give an early warning prompt to the dangerous situation of the obstacle.

[0076] The corresponding relationship between the relative distance level and the alarm mode can be specifically understood as, when the relative distance between the obstacle and the handheld terminal is different, the alarm mode is also different. Generally, the closer the relative distance, the shorter the alarm mod...

Embodiment 3

[0086] The obstacle warning method disclosed in this embodiment is different from the above embodiments in that, on the basis of the above embodiments, functions such as automatic activation of the radar detection device and automatic update of the hazard judgment method are added.

[0087] Those skilled in the art can understand that when the holder of the handheld terminal lowers his head to read for a long time, the functions that the handheld terminal may continue to open include sending and receiving information, browsing the web, reading novels, watching movies, playing games, etc., although the handheld terminal holds Or can manually start or close described radar detection device at any moment, but often can forget to manually start or close described radar detection device in some cases, at this moment, the automatic opening and closing of radar detection device just becomes very important up.

[0088] The specific implementation method is that when the system of the ...

Abstract

An embodiment of the invention discloses an obstacle dangerous case prompting method and a hand-held terminal. The method includes: acquiring information of peripheral obstacles of the hand-held terminal in real time; computing to obtain relative average speed of the obstacles and the hand-held terminal at the current moment by means of a preset time interval and difference values of actual relative distance before and after the preset time interval; computing to obtain estimated relative distances of the obstacles away from the hand-held terminal at the next moment; and performing early warning prompt according to the estimated relative distances of the obstacles away from the hand-held terminal at the next moment. The information of various peripheral obstacles of the hand-held terminal can be acquired in real time, and the estimated relative distances of the obstacles away from the hand-held terminal at the next moment can be computed, so that early warning prompt is performed for a holder of the hand-held terminal according to the estimated relative distances to enable the holder to know threats of various peripheral obstacles to personal safety in advance and make timely response, and further, various dangers or accidents are avoided.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, and more specifically, relates to a method for prompting danger of obstacles and a handheld terminal. Background technique [0002] With the popularization of handheld terminals such as smartphones, pad terminals, and PDAs, more and more users are gradually accustomed to reading with their heads down anytime and anywhere, especially in leisure time such as walking, waiting, and riding. When reading with their heads down, the chances of the holders of these handheld terminals to look up and look at the surrounding conditions are greatly reduced. Moreover, users tend to be immersed in the reading content and ignore the surrounding dangers, such as when walking, encountering people or things around them. Collision, or when encountering theft, the reaction is not timely. [0003] Therefore, based on the occurrence probability of the above-mentioned situation is increasing, there...
