一种通过滑屏实现快速定位的方法及设备
【技术领域】
本发明涉及通信技术领域，特别是涉及一种通过滑屏实现快速定位的方法及设备。
【背景技术】
目前，各种无线通讯设备的应用越来越广泛。人们通过无线通讯设备例如手机来查看文件、阅读邮件、写文章、浏览网页等，因此无线通讯设备的记录信息也越来越多，例如电话号码、邮件地址，各种各样的文件、音乐、图片等。在这些记录信息中快速浏览查找到内容，对于用户而言十分重要。用户的需求还包括例如需要在电话簿中浏览搜索人名，或者在短消息列表中浏览搜索短消息，或者在设置界面中快速浏览搜索某个设置项，或者快速在某个文件夹中浏览查找文件，或者快速在图片中浏览查找图片。
现有技术在带有触摸板上的设备上，浏览文件需要不断地移动手指翻动屏幕，每当完成一页查看，手指必须移动一次甚至几次实现翻页，查看后面的内容。尤其是对于浏览定位的操作，手指需要移动很多次才能看到自己需要的条目。例如，对于一个很长的通信录，用户想要检索H开头的所有名单，而通信录是以A-Z的字母顺序排列的，当打开通信录，第一页总是A开头的名单，用户需要滑动屏幕很多次，直到H的名单出现在屏幕上才能进行真正的检索。如果A-G的名单很多，会使得手指滑屏的次数更多，整个操作会非常麻烦。又例如，一般情况下，系统在屏幕上以列表的形式显示内容，当内容很多时，系统需要很多屏才能显示完所有内容。按现有的方法，从第一屏幕变换到第二屏幕，在触摸屏上是由手指的滑动实现的，比如手指从屏幕下端滑动到屏幕的上端，系统就会相应的把第二页的内容滑动到当前屏幕上来显示，同时也把第一屏幕的内容滑动出当前屏幕。那么内容的屏数越多，手指滑动的次数越多，手指不动，内容也不会变化。
因此，现有技术通过滑屏实现定位的方法对于用户而言并不十分方便，有待改进。

【具体实施方式】
本发明实施例提供一种通过滑屏实现快速定位的方法，能够更简单实现快速定位，提高检索内容速度，更方便用户操作。
图1是本发明实施例的方法流程图。如图1所示，包括：
步骤101、检测用户触摸屏幕后是否发生滑屏行为，所述检测根据手指在屏幕接触原点并滑动到设定位置停止后进行判断；
步骤102、在检测出发生滑屏行为后，调用屏幕内容滚动程序，将从所述原点滑动到设定位置所对应的内容，进行滚动显示；
步骤103、当检测到手指离开屏幕时，停止屏幕内容滚动。
以下进一步更详细介绍本发明实施例的技术方案。
本发明实施例方案的思路是：当用户需要对屏幕的内容进行滚动以快速定位时，例如对条目滚动时，手指先在屏幕上接触一个原点，从原点开始向上或者向下滑动，滑动到某个终点后停下，并保持与屏幕接触。设备内的系统检测到这一系列行为后，便通知相关功能模块开始实施内容自动滚动，滚动的速度由手指从原点到终点的速度决定，滑动得越快，内容滚动的速度越快，当接近检索的内容后，手指便脱离屏幕，则系统指示屏幕内容停止滚动。对于可以跳过的内容，用户通过加快滑动速度，让屏幕内容快速滚动，对于需要逐条查看的内容，则通过缓慢的滑动速度，让屏幕自动逐条滚动。
实现上述自动滑屏的手指操作步骤如图2和图3所示。图2是本发明实施例的手指操作流程图；图3是本发明实施例的手指操作示意图。
如图3所示，手指开始接触屏幕原点，然后向下滑动到终点，并使手指保持不动，屏幕上的内容开始自动向下滚动，滚动速度由原点到终点的速度决定。直到手指离开屏幕位置，滚动停止。
图4是本发明实施例的设备结构示意图。
本发明实施例的设备，一般是指带有触摸板的设备，如手机、平板电脑、个人信息处理器等。此类设备一般都带有接收触摸屏信号的物理接口，以及响应这些物理信号的软件系统。先简单描述该设备中的相关模块的功能，在后续描述中将进行更具体介绍。
触摸屏：作为可以接受触摸的物理器件。
触摸屏驱动模块：执行屏幕内容显示功能，同时在用户对触摸屏进行触摸动作后，收集用户的触摸信息数据并记录到内存模块中。
内存模块：存储触摸信息数据，一般可以是系统内存。
滑屏检测模块：设立一个独立的线程专门用来检测是否有滑屏动作发生，根据内存模块中存储的触摸信息数据进行模式匹配。
屏幕信息处理模块：如果发现有滑屏滚动的处理，那么把滚动的内容信息发送给触摸屏驱动模块，触摸屏便显示滚动的内容。
根据上述结构，当手指接触触摸屏后，触摸屏驱动模块可以获取到触摸信号，本发明实施例涉及的触摸信号包括：
手指的位置信号：对于平面型的触摸屏，一般是（X,Y）坐标信号。
手指的滑动/停止滑动信号：即手指开始在屏幕上滑动/停止滑动。
手指的接触信号：即手指已经接触屏幕。
手指的脱离信号：即手指已经脱离屏幕。
上述各种信号由触摸屏驱动模块获取后，通过物理接口发送给设备内的系统,系统的相关模块根据这些信号，检测手指的操作行为并响应。
系统为每个信号设置一个中断服务程序，当某种行为发生时，获取到信号并触发中断服务程序。该触发行为是系统在开发时定义的，一般系统硬件中会有一个物理内存，称为向量空间。该内存预先定义了当某个中断信号发生时，系统该如何响应和调用哪个程序。比如侦测到某个设定的信号，那么中断服务程序会被立即调用，响应这个中断信号。比如当手指接触屏幕时，中断服务程序便记录下原点坐标(x0,y0),当手指开始滑动时，中断服务程序便为系统记录下每个滑过点的坐标，例如(x1,y1),(x2,y2),(x3,y3)……。这些数据最终都被保存在内存模块中，供系统使用。
系统在滑屏检测模块中运行一个独立的检测线程检测滑屏行为，通过不断检测内存模块中的数据，可以发现以上的滑屏信号的组合，依据具体的数值，进行相应的操作。
图5是本发明实施例方法的具体流程示意图。
如图5所示，包括：
步骤501：检测滑屏行为。
检测滑屏可以由多种方法，以下以一个通过分析数据，检测滑屏行为的实例进行说明，可以判断用户是否有一次滑屏行为。
当中断服务程序记录到手指接触屏幕时（例如第一次接触），中断服务程序为一个事件变量“触摸动作”ActionTouch赋值1，表明发生了第一次接触，当手指开始滑动时候，中断服务程序记录事件变量“滑动触摸”ActionMoveOnTouch为1，同时把每个移动过的坐标记录在一个数据变量MoveList队列中。当手指不滑动时，中断服务程序把事件变量ActionMoveOnTouch赋值为0，同时把滑动开始到滑动结束的时间记录在Movetime数据变量里，该滑动时间通过一个计时器得到。该计时器在ActionMoveOnTouch = 1时候由中断服务程序启动开始计时，在ActionMoveOnTouch = 0 时候，由中断服务程序停止计时，计时差即为滑动时间。当手指脱离屏幕，中断服务程序记录ActionTouch 为0。
当系统发现ActionMoveOnTouch从1变到0，即从滑动变成不滑动，而且同时ActionTouch仍为1时，那么就可以判断出手指还在屏幕上并保持不动，此时符合一次滑屏行为的定义，即手指接触屏幕，发生过滑动，并且最终停滞不动保持接触屏幕。线程会不断检测用户的触摸行为，当发现满足上述条件时候，就可以判断发生了一次滑屏行为。
需要说明的是，为了防止误触发或者接触过于敏感，可以加入各种各样的限定条件，例如ActionMoveOnTouch从1到0，要保持500ms（举例说明但不局限于此）,才可以判断为停滞不动。
又例如设定滑动必须在垂直方向上，才能判断为滑动发生，垂直判定可以通过分析Movelist队列中的所有点的纵坐标，所有点的纵坐标必须和原点的纵坐标的偏差不能超过一个有限范围（看滑动是否在垂直方向上，通过X轴横坐标的偏差确定），这样才可以判断所有的点近似在一条直线上，即用户是在垂直方向上滑动手指。
如果用户希望滑动必须发生在水平方向上，也可以比较横坐标范围来得到（即水平方向看纵坐标）。
总之，上述所有这些限定条件都是为了更好的检测滑屏行为。对于一些触摸板甚至可以直接提供滑屏的物理信号，则不需要系统自己进行判断。
步骤502：确定发生滑屏行为后，调用屏幕内容滚动程序，执行屏幕滚动。
系统发现有滑屏行为时，即通过函数调用的方式，调用屏幕内容滚动程序，执行屏幕滚动。屏幕滚动的速度可以由滑动的距离除以滑动的时间算出，例如垂直方向的滑动距离是原点和终点的纵坐标之差，滑动时间可以从MoveTime变量得到。通过计算就可以得知屏幕内容的滚动速度是多少。
步骤503：判断手指是否离开屏幕，若是，进入步骤505，若否，进入步骤504。
该步骤判断手指是否离开屏幕，可以通过读ActionTouch变量得知，如果它变为0，那么说明手指已经离开屏幕。
步骤504：内容继续滚动。
如果手指没有离开屏幕，那么继续按原来的速度滚动内容。
步骤505：内容停止滚动，数据清零。
如果手指离开屏幕，那么系统立即停止内容的滚动，并且把所有的数据变量MoveTime, MoveList等清零，为下一次滑屏检测做准备。此时线程开始重新检测下一次的滑屏行为。
可以发现，本发明实施例通过简单的滑动-停止的行为定义，实现了简单的可调速度的自动滚屏，极大方便了用户的浏览操作。本发明实施例不仅可以在垂直方向上实施自动滚屏，还可以在水平方向上实施。本发明实施例还可以把该方法扩张到光学手指导航（OFN，Optical Finger Navigation）等使用手指进行操控的设备上。
本发明实施例技术方案与直接拖动滚动条实现屏幕滚动相比，在边浏览边查询的时候，用户可以保持手指不动进行匀速浏览，而用拖动滚动条的方式则手指必须时刻保持匀速移动，而且要很好的控制手指的移动速度，这样才能使得屏幕实现匀速运动。现有方法用户边看边移动手指，需同时控制两个行为，而采用本发明实施例方案用户只需要关注一个行为，即浏览查询。例如用户如果在软件库里面查找希望下载的应用，整个应用列表有成百上千个，每个都浏览下来手指必须移动很多次，而用本发明实施例技术方案只要滑动一次手指就可以，因此大大方便用户使。
