Host, object-based operation system and method

An object-based operation system, comprising:

• a camera, configured to obtain an environment image of an environment around a user;
• a display configured to display information about the environment to the user;
• a storage circuit, configured to store a program code;
• and
• a processor, coupled to the storage circuit and configured to access the program code to execute:
• obtaining the environment image from the camera;
• identifying one or more objects in the environment based on the environment image;
• performing a hand tracking to determine a hand track of a hand of the user;
• determining one or more pointing periods of the one or more objects based on the hand track;
• determining one of the one or more objects as a target object based on the one or more pointing periods;
• and
• performing an object-based operation based on the target object.

An object-based operation method, comprising:

• obtaining, through a camera, an environment image of an environment around a user;
• identifying, through a processor, one or more objects in the environment based on the environment image;
• performing, through the processor, a hand tracking to determine a hand track of a hand of the user;
• determining, through the processor, one or more pointing periods of the one or more objects based on the hand track;
• determining, through the processor, one of the one or more objects as a target object based on the one or more pointing periods;
• and
• performing, through the processor, an object-based operation based on the target object.
