Cyber hand lets net users 'touch' | The Sun |News (https://www.thesun.co.uk/sol/homepage/news/2931764/Cyber-hand-lets-net-users-touch.html)
NEIL MILLARD - The Sun (UK)
Hong Kong scientists have developed a robotic hand that allows people talking over the web to experience the sensation of touching each other - even feeling the strength of a handshake.
The cyber hand can grip and shake as well as make the signs for OK and 'V' for victory.
Professor Liu Yunhui, who led researchers from the Chinese University of Hong Kong, said: "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.
Sophisticated
"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."
Users wear a wrist band which picks up electrical impulses generated by muscles as they contract.
It was originally designed to help the elderly keep in contact with their loved ones in a more personal way.
Prof Liu added: "Although they can show their care through phone calls, physical touch is still a better way to express love.
"The main obstacle we have at the moment is the cost. Our project target was to produce a toy.
"It was intended to be low cost and so there were constraints because of the money we could spend.
"If you want high dexterity it is possible, but you need more motors and you have to spend more money."
The team intend to make progress with future models looking like the human hand - and one day hope to make an entire person which could copy every one of your movements.
The current model is expected to go on sale by Christmas for around å£20 each.
