摘要
随着移动互联网的快速发展和移动触屏技术的广泛应用,滑行输入法以其流畅的交互体验和高效的输入速度,在移动设备上日益受到用户的青睐.针对传统9键拼音键盘滑行输入中拼音重码率高和26键字母键盘滑行轨迹跨度大的问题,设计一款基于六边形按键的中文滑行输入法,摒弃传统键盘中的矩形按键和布局,设计并采用具有更多相邻边的正六边形按键和键盘布局,根据汉语拼音字母组合方案,重构按键中字母映射关系,极力减少滑行轨迹匹配的拼音数,从而降低滑行输入的重码率,实现任何一条有效的滑行轨迹最多匹配4个拼音,平均拼音重码数为1.683,低于传统9键键盘滑行输入的重码数3.002,并在Windows和Android移动平台上进行实现和测试,结果表明,该输入法具备正确稳定的中文输入功能,并具有较高输入效率和较好用户体验.
Abstract
With the rapid development of mobile Internet and the wide application of mobile touch screen technology,sliding input method is increasingly favored by users on mobile devices with its smooth interactive experience and efficient input speed.This paper proposes a Chinese sliding input method based on hexagonal keys to address the issues of high pinyin repetition rate and large sliding trajectory span in traditional 9-key pinyin keyboard sliding input.This input method abandons the rectangular keys and layout in tradi-tional keyboards,and designs and adopts regular hexagonal keys and keyboard layouts with more adjacent edges.Based on the Chinese Pinyin letter combination scheme,we have reconstructed the letter layout in the buttons and made every effort to reduce the number of Pinyin matches for sliding trajectory,thereby reducing the repetition rate of sliding input.This input method ultimately achieves a maxi-mum of 4 Pinyin matches for any effective sliding trajectory,with an average Pinyin weight code of 1.683,which is lower than the tradi-tional 9-key keyboard sliding input weight code of 3.002.Finally,we implemented and tested this input method on Windows and An-droid mobile platforms,and the results showed that it has correct and stable Chinese input function,high input efficiency,and good us-er experience.
