Digits - remote control bracelet

Researchers from the University of Newcastle and the Microsoft Research Center in Cambridge have successfully developed a device that allows users to control any electronic device (such as a mobile phone). or TV) with a simple wave.

The device called Digits is a sensor worn on the wrist. Thanks to its wireless connectivity, Digits users can control devices like cell phones without touching, whether it's in a bag or in another room.

To do so, the device uses a small camera to track the movement of the hand and can identify specific actions, and translate it into commands. For example, when you raise your thumb up, it will understand you want to answer the phone. However, the wearer still has to rely on the headset to talk if the phone is out of reach.

Experts say Digits can even help users use devices that need PINs, such as cash dispensers, safer by entering passwords from within the pocket.
