 新手机装备可远程“发短信” Scientists have devised a way for mobile phone users to operate the device without actually touching it. The technology uses light sensors to monitor where a user moves their hand on their palm and presses the screen on the phone accordingly. It means people can decline a call with the phone still in their pocket or send a text while simply drawing on their hand. In the experiments the light sensors were linked up to a camera installed on the user's head, but the researchers hope that one day it will be as small as a button。 科学家近日发明了一种手机装备，人们不用直接接触手机便可使用手机各项功能。据了解，这项技术使用光敏感元件来检测用户在手掌上移动的位置从而 相应地在手机屏幕上按下按键。这意味着即使手机在衣兜里人们也可以直接拒接来电，或者直接在手上写写画画便可发送一条短信。试验中的光敏感元件需佩戴于头 部，但研究人员希望有朝一日其大小可同按钮媲美。 |
