Description

一种双指手势文字输入方法 技术领域:
本发明涉及一种双指手势文字输入方法。 背景技术:
随着触摸屏技术在电子产品领域的普及, 使用触摸屏技术的软件虚拟键盘, 亦称作软 键盘的文字输入方式也得到普遍应用。 但是, 目前已知软键盘输入方式与传统的机械键盘 相比, 体验感较差。 具体而言, 由于没有传统机械键盘按键的触感, 软键盘使用者在输入 字符时无法只凭手感进行盲打, 必须用目视保证输入准确度, 使用者需要同时关注相距较 远的文本编辑区和软键盘的每一个键位的位置, 输入效率低。 尤其对于平板电脑而言, 因 为使用者经常在缺少桌面等支撑物的情况下以双手持握操作, 当使用者以双手持握方式输 入文字时, 拇指在输入过程中有过长的操作距离, 这也降低了输入效率。
例如, 申请(专利)号为 CN95111187. 6 的一种文字的计算机输入方法及相应的键盘, 其特征是在键盘平面的一维顺序以音节辅音发音字母排序或从部首边旁的笔划数数目为 序, 键盘平面的另一维以元音字母数目或音节数为序或笔划数为序。
例如, 申请 (专利) 号为 CN94109513. 4 的一种手写文字输入方法, 当手写输入文字 时, 把它分解为 a〜f 的子字符, 并且, 把子字符 a〜f 中相邻的子字符组合成指定的数量, 识别为 1个文字。 在检测手写输入的文字各笔划的笔迹特征, 利用检测的上述特征量识别 子字符并将上述子字符组合后识别文字的手写文字输入方法中, 备有行切割规则和子字符 切割规则, 当输入上述笔划时, 根据该笔划的特征、 上述子字符和上述行切割规则判断输 入的行, 当输入的上述行与以前输入的行是同一行时, 根据上述笔划的特征、 上述子字符 和上述子字符切割规则, 进行上述子字符的判断。
例如, 申请 (专利) 号为 CN99101082. 5 的一种规定外字母文字的输入方法, 其通过 把输入的规定字母进行文字变换,能简单且迅速地输入规定外字母的文字输入方法及其装 置。 在该方法及其装置中,输入能直接输入的规定字母文字中所希望的规定字母文字。 调 出不能够直接输入的规定外字母文字中与上述输入的所希望的规定字母文字组合的至少 1 个规定外字母文字。 选择该至少 1个规定外字母文字中所希望的 1个规定外字母文字。 进 行从上述输入的所希望的规定字母文字向上述选择的所希望的规定外字母文字的文字变 换。 再例如, 申请 (专利) 号为 CN03112279. 5的 数字小键盘及拼音文字输入方法, 属于 拼音文字的计算机数字小键盘的输入方法技术领域。 全能数字小键盘包括数字字母键、 符 号键和功能键, 设有几个备用键可安排便捷键或触摸鼠标及其左右键, 可以替代现行的英 文大键盘。 其中, 数字字母键中的字母为可变部分, 它将根据不同文字的字母代码将每个 字母分配在对应的数字键上, 以满足任何一种文字进行计算机数字输入, 键盘排列格式为 竖排式和横排式。 拼音文字输入方法中的编码方法包括字母编码、 单词编码、 词语编码三 部分。
但是上述专利和技术均没有解决单指文字输入的技术问题。 发明内容:
为了克服已知软键盘体验感差、 输入效率低的问题, 本发明提供一种双指手势文字输 入方法, 使用者只需在便于单指操作的两个活动区内以单指手势指示方式, 通过单指划动 的方向和距离的不同, 确定并输入不同的字符, 本发明包括以下步骤:
( 1 ) 将角度范围值、 距离范围值、 活动区编号这三个数值变量赋值到字库中的相应的 字符上; 使字库中的每一个字符都具体对应一组相应的角度范围值、 距离范围值、 活动区 编号这三个数值变量; 所述角度范围值是手指抬起点坐标与手指按下点坐标间的相对角 度; 所述距离范围值是手指抬起点坐标和手指按下点坐标间的相对距离; 所述活动区编号 是手指按下点所在活动区的编号;
(2) 当使用者的手指在触摸屏上的活动区里按下, 即获得一个按下点坐标和按下点所 在活动区的编号;
( 3) 当使用者的手指在触摸屏上划动一段距离后抬起时, 即获得一个抬起点坐标;
(4) 当以下三个数值: 即步骤 (3) 中的手指抬起点坐标与步骤 (2) 中的手指按下点 坐标间的相对角度、 步骤 (3) 中的手指抬起点坐标和步骤 (2) 中的手指按下点坐标间的 相对距离、 以及步骤 (2) 中的手指按下点所在活动区的编号符合在步骤 (1 ) 中已经设定 好的赋值在字库中的某一个字符的数值范围要求, 则输入此字符。
本发明与目前现有的软键盘文字输入需要目视确定准确的按键位置不同, 本发明用相 对方向和距离代替固定键位, 大大降低了文字输入对使用者操作精确度和文字输入技能的 要求, 简化了文字输入的过程, 并可实现凭借手感快速输入, 极大地提高了文字输入效率, 适用范围广, 具有较强的实用价值。 附图说明: 图 1是本发明所述一种双指手势文字输入方法的实施例的软件界面示意图; 图 2是本发明所述一种双指手势文字输入方法的实施例的局部放大图;
