Embodiment Construction

[0020] The following is attached image 3 , the present invention will be further elaborated by describing specific embodiments in detail.

[0021] A method for triggering screen capture by tapping the screen with finger joints, comprising the following steps:

[0022] Step 1: The acceleration sensor and the touch screen are in the state of constant sensing;

[0023] Step 2: When a picture to be captured appears on the screen of the smart terminal, the user uses a single finger joint to tap any same area of ​​the touch screen 2 times (or 3 times, or even more times) continuously within a certain period of time. );

[0024] Step 3: After the user taps the touch screen of the smart terminal for the first time, when the acceleration sensor detects the change of the acceleration vector, the smart terminal judges whether the change has reached the preset value Δg;

[0025] Step 4: After the user taps the touch screen of the smart terminal for the first time, when the touch scree...

Abstract

The present invention discloses a method for triggering screen capturing by tapping a screen with a finger joint. The method comprises: step 1: when a picture needed to be captured appears on a screen of an intelligent terminal, a user tapping any same area of a touch screen twice with a single finger joint in a certain period of time; step 2: when the first tap occurs, determining whether an acceleration sensor senses an event with an acceleration vector change value exceeding a preset value, and whether the touch screen senses a valid touch event at the same period; step 3: starting a timer for timing; step 4: when the second tap occurs, determining whether an event with the acceleration vector change value exceeding the preset value exists, and whether a valid touch event occurs at the same period; step 5: determining whether the effective distance between locations of early and later touch operations in the screen is smaller than a preset value; and step 6: performing screen capturing. The method disclosed by the present invention implements automatic screen capturing by determining the size and the number of times of the acceleration vector changes caused by finger tapping on the screen, and the occurrence number and the location of a corresponding tapping and touching event, so that a picture or text information in which the user is interested can be easily and conveniently captured.

Description

technical field [0001] The invention relates to a method for capturing a screen by an intelligent terminal, in particular to a method for triggering a screen capture by tapping on a mobile terminal with an acceleration sensor and a touch screen. Background technique [0002] Mobile terminals have become an indispensable communication and entertainment tool in people's work and life. With the popularity of smart phones, screen capture operations have become an indispensable function of mobile terminals. Due to many reasons such as appearance cost, it is impossible to set a single button for the screen capture function, so the screen capture function is often realized by combining buttons, such as the power button plus the volume up and down buttons, or adding some virtual buttons, but it is not easy to operate. Convenience, user experience is not good. Contents of the invention [0003] The purpose of the present invention is to provide a method of intelligent screen capt...
