Now comes a robotic hand that allows you to hold hands with your loved ones over the Internet - created by Hong Kong scientists.
The cyber-hand plugs into a computer and communicates with an electronic wristband to allow people talking over the Internet to experience the sensation of touch.
The hand can grip and shake as well as give the signs for 'OK' and 'V' for victory.
It also picks up the strength of the hand movement and is capable of giving a weak or a firm handshake.
"At this moment the function is not perfect and it can't copy exactly, partly because the robot hand is different from the human hand in terms of the degree of freedom of movement it has," the Sun quoted Professor Liu Yunhui, who led researchers from the Chinese University of Hong Kong, as saying.
"There are also a few errors such as delays in processing and mechanical problems. But in the future it will be possible to produce more sophisticated and more dextrous movements," Yunhui added.
The current model is expected to go on sale by Christmas for around 20 pounds each.
