Smartwatch Patent For Google
This isn't the first smartwatch patent Google has submitted to the USPTO, but it does seem their most interesting.
The bezel, not just the screen seems to provide some sort of touch interaction, as does two touchpad areas on the wristband above and below the watch face itself.
Given the small screen size, that does seem like it could greatly enhance usability.
The touchpads on the wristband can also communicate with other devices in the 'data pipeline' - Phone or even Glass?
