1. A method of controlling an electronics device via hand gestures, comprising: detecting, via an image processing module of the electronics device, a bare-hand position via a camera input based upon a detected sequence of bare-hand positions; determining whether the bare-hand position has been detected for a threshold duration of time; identifying the detected bare-hand position from a vocabulary of hand gestures, where the identified bare-hand position comprises a hand gesture associated with powering on the electronics device; and controlling, in response to determining that the bare-hand position has been detected for the threshold duration of time, the electronics device in response to the identified bare-hand position by powering on the electronics device.
