The wristband consists of four pair of electrodes which comes under the screen of the watch and the ring on the finger emits continuous high-frequency A/C signals whenever in contact with the arm. The electrodes in the band utilise these signals for tracking the finger movements. Out of the two pairs, one pair of electrodes is used to monitor X-axis movement and another one to find the Y-axis position.

It turns your hand to a touchpad, which is an extension of the touchscreen of the device.

It comes very handily for giving commands because at times the tiny screen can be tough to use. It allows a larger area to interact with the smart watch. The technology used makes it so simple to the user to control the device with little movements by the finger.

We can dial a phone number, play music, selecting apps/items, and play games like angry birds or fruit ninja. The developers of the technology had opined that the touch sensitivity is 99% accurate and would give more comfort than the regular touch screens.

Different functionalities are assigned to each gesture such as swiping right is for selecting, swiping left for creating shortcuts, etc. It is very compact, low-cost & consumes less power.

The technology developed is not the first of its kind but the most stylish of all the others. The makers are looking to indulge this new tech into future smart watches which would make it more user-friendly and exciting.
