A non-transitory computer readable storage medium, the computer readable storage medium recording an executable computer program, the executable computer program being loaded by a host to perform steps of:

• determining whether information of a hand is enough for identifying a hand gesture of the hand;
• in response to determining that the information of the hand is enough for identifying the hand gesture, identifying the hand gesture, receiving first hand gesture information from at least one external gesture information provider, and correcting the hand gesture based on the first hand gesture information;
• in response to determining that the information of the hand is not enough for identifying the hand gesture, receiving second hand gesture information from the at least one external gesture information provider, obtaining a predicted hand gesture, and obtaining the hand gesture based on the predicted hand gesture and the second hand gesture information, wherein the second hand gesture information comprises more hand gesture information than the first hand gesture information.
