Volume control method and system with audio and visual synchronization feedback

Abstract

The invention discloses a volume control method and system with audio and visual synchronization feedback. The method comprises the following steps: setting a touch screen control interface, wherein the touch screen control interface comprises a touch area and a figure representing a volume level, wherein the figure representing the volume level comprises a plurality groups of LED light sources equidistantly arranged at the rear end portion of a touch screen; performing a manipulation action on the touch screen, and acquiring corresponding coordinates and a touch event; matching the coordinates and the touch event to obtain a volume value, and controlling the volume level according to the obtained volume value; and converting the volume value to an opening and closing quantity value of an LED light via a function module, and controlling opening or closing of a corresponding number of the LED lights according to the opening and closing quantity value. According to the method and system, a blind operation is satisfied; sight separation is avoided; a problem that a rapid volume change cannot be realized by an electronic button is solved; a problem that an visual change cannot be realized by mechanical button regulation is solved; a problem that an UI figure regulating the volume in the display screen needs high precision alignment is solved; and precise regulation of a user under a steady operation is satisfied.

Description

technical field [0001] The present invention relates to the technical field of data transmission and storage, and in particular, to a volume control method and system for synchronous feedback of listening and vision. Background technique [0002] As all kinds of electronic products become more and more intelligent, people also require more and more intelligent operation experience of various products or equipment, more and more convenient, intuitive, WYSIWYG user demand is more and more intense. Or the volume adjustment and display of the device cannot be intelligent, convenient, intuitive, and what you see is what you get; even the sound and image cannot be fed back to the operator at the same time. The common implementation methods of volume adjustment in existing products or devices are: ① Mechanical knob or button, ② electronic device knob or button, ③ graphical interface overlay operation on the display screen. SUMMARY OF THE INVENTION [0003] In order to overcome t...
