Google might be facing mounting criticism against Google Glass. But Google is going ahead with improving the device, as it does look like a device for the future.

Google patented a method for using nasal vocalizations to control Google glass. Sensors are embedded in nose pads to sense nasal vocalizations. User performs affirmative vocalizations like Um-hum to select available option and Negative vocalizations like Mm-mm are used to negative options on the screen.

The patent makes it easier to use Google Glass and brings it more closer to the human experience!!!
