We are all looking for the next thing in tech and manufacturers are not so different from us. Something that is innovative, might catch on, and they can quickly patent !!! In this case Samsung has a new design patent awarded to the company that shows a round smartwatch that is operated by a ring around the display.
This quick rotary input mechanism is found on Smat Camera's and other devices like sports watches. It is early days to know if this feature will come to market anytime soon, or if it will be found on a future Tizen Smart Watch, but I really like the added dimension that it brings.
