研究人员研发新式拇指键盘 手机打字更高效
<p>来自英国、德国及美国的研究人员共同研发了一款适合双手拇指同时打字的虚拟键盘应用，能够将平板及智能手机用户的打字速度从现在的每分钟20个字提高到每分钟37个字，而且打字体验更加舒适自如。参与研发的圣安德鲁斯大学一位博士表示，传统<span word="Qwerty">Qwerty</span>键盘将用户局限在“不够理想的文字输入界面”。新键盘的研发人员利用计算优化技术设置字母的排序，比如，使用频率较高的字母集中在键盘中区，以期让用户在打字时减少拇指移动的时间，从而提高打字速度。我们现在使用的标准键盘是以主键盘字母区左上角6个字母的连写<span word="Qwerty">Qwerty</span>来命名的，此次新研发的键盘则以主键盘右下角的四个字母连写命名为<span word="KALQ">KALQ</span>。研发人员将于今年5月1日在巴黎召开的美国计算机协会会议上展示该应用，之后该应用将免费供安卓用户下载使用。</p><p><span word="Researchers">Researchers</span> <span word="have">have</span> <span word="created">created</span> <span word="a">a</span> <span word="new">new</span> <span word="keyboard">keyboard</span> <span word="layout">layout</span> <span word="which">which</span> <span word="they">they</span> <span word="claim">claim</span> <span word="makes">makes</span> "<span word="thumb">thumb</span>-<span word="typing">typing</span>" <span word="faster">faster</span> <span word="on">on</span> <span word="touchscreen">touchscreen</span> <span word="devices">devices</span> <span word="such">such</span> <span word="as">as</span> <span word="tablets">tablets</span> <span word="and">and</span> <span word="large">large</span> <span word="smartphones">smartphones</span>.</p><p><span word="Dr">Dr</span> <span word="Per">Per</span> <span word="Ola">Ola</span> <span word="Kristensson">Kristensson</span>, <span word="from">from</span> <span word="St">St</span> <span word="Andrews">Andrews</span> <span word="University">University</span>, <span word="said">said</span> <span word="traditional">traditional</span> <span word="Qwerty">Qwerty</span> <span word="keyboards">keyboards</span> <span word="had">had</span> <span word="trapped">trapped</span> <span word="users">users</span> <span word="in">in</span> "<span word="suboptimal">suboptimal</span> <span word="text">text</span> <span word="entry">entry</span> <span word="interfaces">interfaces</span>".</p><p><span word="The">The</span> <span word="new">new</span> <span word="design">design</span> <span word="has">has</span> <span word="been">been</span> <span word="dubbed">dubbed</span> <span word="KALQ">KALQ</span>, <span word="after">after</span> <span word="the">the</span> <span word="order">order</span> <span word="of">of</span> <span word="keys">keys</span> <span word="on">on</span> <span word="one">one</span> <span word="line">line</span>.</p>
