Californian start-up Tactus has developed a sheet of transparent buttons that rise up out of a touch screen and disappear, the Daily Mail reported.

The company claims that the sheet only takes up the same amount of room as the layer of transparent glass found in current touch screens.

The technology could be used in tablets, phones and remote controls. It could even allow for touch screens to be played with the same precision that people use to play musical instruments with. （点击英国《每日邮报》网站查看原文）

未来手机将有隐形键盘

       据英国《每日邮报》报道，美国加州一家名为“触觉”的创业公司开发了一款透明键盘按钮——需要使用的时候，键盘可以从手机触摸屏中升起来，不用的时候就会消失。

       该公司表示，这一层键盘仅仅藏在普通手机触摸屏幕的透明玻璃层中。

       这种技术可以被应用在平板电脑、手机和遥控器中。它还能够在触摸屏幕上演奏出如乐器般精准的音乐。
