平板电脑等设备或实现用眼睛操控
<p>不久的将来，人们手中的智能手机和平板电脑就或许可以用眼睛来操控了。一直致力于研究帮助残障人士用眼睛控制电脑技术的公司<span word="GazeGroup">GazeGroup</span>打算将该技术应用于适合普通用户使用的领域，这样不但能惠及更多人，同时还能明显降低此类技术的使用费用。据悉，该技术通过电脑设备向用户脸部投放红外光线，在校准用户的眼睛活动方式之后，该技术便可轻松感知用户眼睛活动的方向，并由此控制电脑光标。该公司负责人表示，虽然目前大部分智能手机和移动设备都未配备红外装置，不过他们可以通过安装屏幕过滤器来使用该技术。</p><p><span word="In">In</span> <span word="the">the</span> <span word="near">near</span> <span word="future">future</span>, <span word="we">we</span> <span word="may">may</span> <span word="be">be</span> <span word="using">using</span> <span word="our">our</span> <span word="eyes">eyes</span> <span word="to">to</span> <span word="operate">operate</span> <span word="our">our</span> <span word="smartphones">smartphones</span> <span word="and">and</span> <span word="tablets">tablets</span>, <span word="even">even</span> <span word="when">when</span> <span word="it">it</span> <span word="comes">comes</span> <span word="to">to</span> <span word="playing">playing</span> <span word="popular">popular</span> <span word="games">games</span> <span word="like">like</span> <span word="Fruit">Fruit</span> <span word="Ninja">Ninja</span>.</p><p><span word="NPR">NPR</span> <span word="profiled">profiled</span> <span word="the">the</span> <span word="GazeGroup">GazeGroup</span>, <span word="which">which</span> <span word="has">has</span> <span word="been">been</span> <span word="developing">developing</span> <span word="eye">eye</span>-<span word="controlled">controlled</span> <span word="computer">computer</span> <span word="technology">technology</span> <span word="for">for</span> <span word="nearly">nearly</span> 20 <span word="years">years</span>. <span word="But">But</span> <span word="those">those</span> <span word="devices">devices</span> <span word="have">have</span> <span word="been">been</span> <span word="primarily">primarily</span> <span word="designed">designed</span> <span word="to">to</span> <span word="aid">aid</span> <span word="those">those</span> <span word="with">with</span> <span word="disabilities">disabilities</span>, <span word="and">and</span> <span word="are">are</span> <span word="typically">typically</span> <span word="very">very</span> <span word="expensive">expensive</span>.</p><p>"<span word="After">After</span> <span word="a">a</span> <span word="while">while</span>, <span word="we">we</span> <span word="figured">figured</span> <span word="out">out</span> <span word="that">that</span> <span word="probably">probably</span> <span word="the">the</span> <span word="best">best</span> <span word="way">way</span> <span word="is">is</span> <span word="to">to</span> <span word="go">go</span> <span word="for">for</span> <span word="a">a</span> <span word="mass">mass</span>-<span word="market">market</span> <span word="approach">approach</span>," <span word="says">says</span> <span word="Gaze">Gaze</span>'<span word="s">s</span> <span word="Sune">Sune</span> <span word="Alstrup">Alstrup</span> <span word="Johansen">Johansen</span>.
