A device and method for adjusting volume using micro-expressions

Abstract

The invention provides an apparatus and method for adjusting the volume by using micro-expressions. The apparatus is arranged in a playing terminal having a playing portion and a camera for adjustingthe external volume of a video when the video played by the playing terminal is switched. The apparatus for adjusting the volume by using micro-expressions is based on the method for adjusting the volume by using the micro-expressions. The method comprises the following operation steps: step 101, when it is monitored that the playing terminal has a video being played, starting the present method;step 102, detecting a termination volume peak value; step 103, capturing a first eyebrow micro-expression; step 104, detecting a starting volume peak value; step 105, judging whether the volume has asignificant enhancement feature; step 106, if the judgment result is negative, performing no adjustment; step 107, if the judgment result is positive, capturing a second eyebrow micro-expression; step108, judging whether the eyebrow has a shrink feature; step 109, if the judgment result is negative, performing no adjustment; step 110, if the judgment result is positive, reducing the volume; and step 111, ending the present method.

Description
