Strap turns your finger into a phone

BBC Click's Marc Cieslak reports on a device that allows one of your fingers to make phone calls.

A strap which effectively turns one of your fingers into a phone - which can send and receive calls -has been developed.

The strap sends vibrations down the wearer’s hand and can be fitted to any watch.

BBC Click's Marc Cieslak tried it out at the CES tech show in Las Vegas.
