  • Patent number: 12681584
    Abstract: A method of object movement control is proposed. The method includes: in response to a hand gesture of a hand of a user being a predefined selection gesture, determining a target object corresponding to the hand gesture; in response to the hand gesture of the hand of the user changing to a predefined movement confirmation gesture, determining a target display position; and controlling the target object to be displayed at the target display position. Therefore, movement control of an object according to a hand gesture operation and “bare hand” control of an object can be achieved. This further enhances user experience of operations while improving the operation intelligence of object movement control.
