Scientists have devised a way for mobile phone users to operate the device by tapping their palm.
It works by linking light sensors to a camera installed on the user's head.
Light sensors are used to monitor where a user moves their hand on their palm and presses the screen on the phone accordingly.
The team from Hasso Plattner Institute at Potsdam University in Germany believes the breakthrough - dubbed "iPalm" - could make using a remote control far easier.
The technology allows people to decline a call with the phone still in their pocket or, send a text while drawing on their hand.
Lead researcher Patrick Baudisch told New Scientist that he hopes to shrink the camera so that it is so small it won't even be noticed.
"Ultimately, we envision the camera becoming so small that it integrates into clothing, such as the button of a shirt, a brooch, or a pendant", he said.



手机用户可以通过触摸手掌实现对手机的操作，这是科学家最近的一项新发明。

这项发明需要用户把光敏元件与一个固定在头部的摄影机相连接。
光敏元件的作用是监测手机用户触摸手掌的位置来对手机屏幕进行相应操作。

来自德国波茨坦大学哈索•普拉特纳研究院的研发团队给这项突破性发明命名为"iPalm",运用这项发明，远距离操作可以很容易的实现。
这项技术使人们不必拿出放在口袋里的手机，也能够挂掉电话；在手掌上写写画画就可以发信息。

《新科学家》杂志援引了这项发明的主要负责人帕特里克•博迪斯科的话，他希望安装在人头部的摄影机可以尽量小巧一点，这样它就不会显得这么惹眼了。

帕特里克说："我们想象一下，如果这个摄影机非常小巧，我们就可以把它放进衣服里，像衬衫扣子、胸针、或是项链的坠子一样。"
