本发明涉及音视频播放多级快进/快退手势方法和设备，具体涉及一种利用多点触摸下的滑动实现音视频播放多级快进/快退的手势方法和设备。The invention relates to a multi-level fast forward/reverse fasting gesture method and device for audio and video playback, and particularly relates to a gesture method and device for realizing multi-level fast forward/reverse playback of audio and video playback by sliding under multi-touch.
常规的音视频播放控制通过遥控器或电脑键盘进行。电脑键盘过于笨重，遥控器对于需要频繁切换音视频源的应用而言过于繁琐。自从Apple公司于2007年发布iPhone以来，手势控制已经普及到了老人小孩无有不会的程度。现在是该为音视频播放控制引入一个重大变化的时候了。Conventional audio and video playback controls are performed via a remote control or a computer keyboard. The computer keyboard is too cumbersome, and the remote control is too cumbersome for applications that need to frequently switch audio and video sources. Since Apple released the iPhone in 2007, gesture control has spread to the extent that older people can't. It is time to introduce a major change in audio and video playback controls.
一些手机音视频播放器已经引入了部分手势操作，例如左滑快退(Rewind)、右滑快进(Fast Forward)，Youtube引入了左侧双击快退10”、右侧双击快进10”的手势(以及N+1左/右侧点击快退/进N×10”)。然而，有时候消费者需要多级快进/快退，譬如分别快进/快退10”、1'、10'等，尤其对于需要快速随机跳转视频的场景而言，根据滑动速度决定快进/快退速度无法精确控制，完全靠频繁点击加快跳转速度亦不可取。消费者需要的是准确、快捷的多级跳转手势。Some mobile audio and video players have introduced some gesture operations, such as Rewind and Fast Forward. Youtube has introduced a double-click on the left to rewind 10" and a double-click on the right to fast forward 10". Gestures (and N+1 left/right click rewind/into N×10). However, sometimes consumers need multi-level fast forward/rewind, such as fast forward/rewind 10”, 1', 10 respectively. 'Equivalent, especially for scenes that require fast random jump video, it is not possible to accurately control the fast forward/rewind speed according to the sliding speed. It is not advisable to speed up the jump speed by frequent clicks. What consumers need is an accurate and fast multi-level jump gesture.
发明概述Summary of invention
现在的触摸板/触摸屏等能感应触摸的装置都开始支持或已经支持多点触摸了。然而，音视频播放的多级快进/快退通常需要依靠遥控器或键盘。我们可以通过多点触摸来实现音视频播放的多级快进/快退。Devices that can sense touch, such as touchpads/touchscreens, are now supported or already support multi-touch. However, multi-level fast forward/rewind of audio and video playback usually requires a remote control or a keyboard. We can multi-level fast forward/rewind of audio and video playback through multi-touch.
最简单的实施例如下：The simplest implementation is as follows:
·单点左/右滑，每一次快退/快进10”· Single point left/right slip, each rewind/fast forward 10”
·双点左/右滑，每一次快退/快进1'·Double-point left/right slip, each rewind/fast forward 1'
·三点左/右滑，每一次快退/快进10'· Three-point left/right slip, each rewind/fast forward 10'
播放控制和音视频播放，可以是：Play control and audio and video playback, can be:
·整合于一个相同的设备，例如手机和平板，直接在播放的触摸屏滑动· Integrated on one of the same devices, such as mobile phones and tablets, sliding directly on the touch screen
·通过两个不同装置，例如笔记本电脑和电视，通过屏幕播放音视频，在另外一块触摸屏或触摸板滑动，以控制音视频多级快进/快退· Control audio and video multi-level fast forward/reverse by playing audio and video through the screen through two different devices, such as laptops and TVs, and sliding on another touch screen or touchpad

本发明公开了一种音视频多级快进/快退的手势控制方法，其实施例主要聚焦于触摸屏和触摸板。然而，本发明的实施例不限于专用的手势控制装置。例如，通过手机或平板电脑，与电视等设备进行多屏互动，也可以利用下面描述的技术方案，比如将手机兼作为手势控制装置。The invention discloses a multi-level fast forward/reverse gesture control method for audio and video, and an embodiment thereof mainly focuses on a touch screen and a touch panel. However, embodiments of the invention are not limited to dedicated gesture control devices. For example, through a mobile phone or a tablet computer, multi-screen interaction with a device such as a television can also utilize the technical solution described below, such as using a mobile phone as a gesture control device.
为了区分快进/快退，需要判断滑动方向。不仅为了区分快进/快退，也需要区分多级快进/快退的手势，与其他音视频播放控制的手势。我们假定用户滑动手指的时候，并未精确的按照绝对水平的方向进行。那么可以把滑动轨迹分解为水平/垂直两个方向的移动分量。如果水平移动大于垂直移动，并且为向左，则按向左滑动进行对应等级的快退；如果水平移动大于垂直移动，并且为向右，则按向右滑动进行对应等级的快进。In order to distinguish between fast forward/rewind, it is necessary to judge the sliding direction. Not only to distinguish between fast forward/rewind, but also to distinguish between multi-level fast forward/reverse gestures, and other audio and video playback control gestures. We assume that when the user slides the finger, it does not exactly follow the absolute horizontal direction. Then the sliding trajectory can be decomposed into moving components in both horizontal and vertical directions. If the horizontal movement is greater than the vertical movement and is to the left, slide to the left to perform the rewind of the corresponding level; if the horizontal movement is greater than the vertical movement and to the right, slide to the right to advance the corresponding level.
通常，两个或三个等级的快进/快退已经够用，而对于较小的触摸控制设备(例如普通笔记本的触摸板)，五根手指滑动的空间过于狭小，可以将最高等级的向左/右滑动(三根或四根手指滑动)设定为前一个/后一个音视频源。Usually, two or three levels of fast forward/rewind are enough, and for smaller touch control devices (such as the touchpad of a normal notebook), the space for five fingers to slide is too narrow, and the highest level of orientation can be used. The left/right slide (three or four finger slides) is set to the previous/next audio source.
