Abstract:
1. A control method of a digital device using a Head Mounted Display (HMD) and an external digital device, the HMD displaying a first display object and the external digital device displaying a second display object independent and different from the first display object, the method comprising: determining whether the HMD is linked with the external digital device; detecting a positional state of the external digital device linked with the HMD, wherein the positional state includes a first state in which the external digital device is located in a predetermined view angle region of the HMD and a second state in which the external digital device is located outside of the predetermined view angle region of the HMD when the HMD is linked with the external device; detecting a gesture input of a user when the external digital device is in the first state, wherein the gesture input is located between the first display object displayed on the HMD and the second display object displayed on the external digital device; while the first and second display objects are being displayed and are seen by the user respectively on the HMD and the external digital device, determining whether the second display object shown to the user on the external digital device is different from the first display object being displayed on the HMD; detecting a pointing direction of the gesture if the second display object being displayed and shown to the user on the external digital device is different from the first display object being displayed on the HMD; while the HMD and the external digital device are displaying respectively the first display object and the second display object which is shown to the user and is different from the first display object, determining which one of the HMD and the external digital device is to be a control device which is to be controlled by the gesture input based on the pointing direction of the gesture input, wherein if the pointing direction of the gesture input points toward the HMD, the HMD is determined to be the control device, and if the pointing direction of the gesture input points toward the external digital device, the external digital device is determined to be the control device; and controlling the first display object displayed on the HMD based on the gesture input when the HMD is determined to be the control device or controlling the second display object displayed on the external digital device based on the gesture input when the external digital device is determined to be the control device, wherein during the controlling of the first or the second display object, the HMD and the external digital device are displaying respectively the first display object and the second display object which is shown to the user and is different from the first display object.
