Claim Text:
1. A method for controlling a content on an electronic device by detecting hand gestures and head gestures, comprising steps of: (a) detecting, via a processor, a head region and a hand region of a user by analyzing an input image from a camera in electronic communication with said processor with an object detection technology; (b) tracking the gestures in the head region and the hand region of the user by using a computer vision technology including said camera; and (c) allowing the content on the electronic device to be controlled by referring to gestures-combining information including data on the tracked gestures in the head region and the hand region, wherein, at the step (b), data on the gestures are acquired by storing data acquired by tracking, via the camera, a face, a central point of a palm of a hand, and fingers of the user for a predetermined time, wherein the step (c) includes the steps of: (c4) expressing, via the processor, a movement trajectory in an autoregressive model with reference of the data on the gestures acquired via the camera and stored for the predetermined time; (c5) applying, via the processor, a hidden Markov model (HMM) to the movement trajectory data expressed in the autoregressive model; and (c6) recognizing, via the processor, the data where the HMM is applied as a special command for controlling the content on the electronic device by comparing the data where the HMM is applied with prefixed command signal data in a motion dictionary database in electronic communication with the processor.
