Method and device for adjusting video playing parameters by means of fingerprint identification

Abstract

The invention discloses a method and device for adjusting video playing parameters by means of fingerprint identification. The method and device are used for an electronic device with a touch screen, and the touch screen has the fingerprint identification and touch identification functions. The method comprises the following steps of judging whether fingerprints operating the touch screen are matched with the fingerprints of at least one pre-stored user; if the fingerprints operating the touch screen are matched with the fingerprints of the pre-stored user, obtaining the operation motion trail of the fingerprints, calculating the length of the motion trail, and judging whether the fingerprints move towards the first side of the touch screen or the second side, opposite to the first side, of the touch screen; if the fingerprints move towards the first side, increasing the video playing parameters according to the preset video playing parameters and the motion distance of the fingerprints; if the fingerprints move towards the second side, reducing the video playing parameters according to the preset video playing parameters and the motion distance of the fingerprints. According to the method and device, the video playing parameters are adjusted through the device with the touch screen, use is convenient and direct, and user experience is better.

Description

technical field [0001] The invention relates to the field of video playing, in particular to a method for adjusting video playing parameters by using fingerprint identification and a device for realizing the method. Background technique [0002] With the continuous development of smart phones, playing videos on mobile phones, such as watching movies, watching TV and other multimedia applications has been very extensive, but the video players currently used on mobile phones are all played by dragging the progress bar in the player. Realize the fast forward or rewind of the video progress, adjust the playback volume by clicking the volume button, or adjust the volume through the volume adjustment button on the mobile phone. In this way, the user experience is very poor, and since the screen of a smart phone is generally small, the progress bar in the player is even smaller, it is difficult for the user to select the progress bar on the screen of the mobile phone, and it is dif...

Problems solved by technology

In this way, the user experience is very poor, and since the screen of a smart phone is generally small, the progress bar in the player is even smaller, it is difficult for the user to select the progress bar on the screen of the mobile phone, and it is difficult to drag, which is very inconvenient to use. Moreover, using the volume adjustment keys to adjust the volume will also cause wear and tear on the keys, or even damage them.

[0003] However, the current touch technology on smartphones can recognize at least one touch point on the screen, that is to say, it can recognize fingers sliding or touching on the screen. Although this technology has been applied to video players, it must The operation can only be performed in conjunction with the playback menu, and the playback menu itself will cover part of the video screen, making it impossible for users to see the complete screen, resulting in poor user experience
