Augmented reality device and operating method of the same
A method for operating an augmented reality (AR) device includes identifying a first object from an image of the first object obtained through a camera, identifying a grip position at which a user grips the first object, and performing an operation based on the grip position.
1 . A method of operating an augmented reality (AR) device, the method comprising:
identifying a first object from an image of the first object obtained through a camera;
identifying a grip position at which a user grips the first object;
identifying a rotation of the first object; and
performing an operation based on the grip position and the rotation of the first object.
2 . The method of claim 1 , wherein the identifying the grip position comprises:
identifying at least one feature point from the image;
identifying a hand of the user based on the at least one feature point; and
identifying the grip position based on a position of the hand of the user and a position of the first object.
3 . The method of claim 1 , wherein a lengthwise area of the first object is divided into sections that respectively correspond to different operations of the AR device, and the sections represent a percentage of area of the lengthwise area of the first object.
4 . The method of claim 1 , wherein the first object is divided into sections that respectively correspond to different operations of the AR device.
5 . The method of claim 1 , further comprising providing the user with a virtual image of a guide to operation types respectively corresponding to different grip positions.
6 . The method of claim 1 , further comprising:
in case that the user contacts the first object at a plurality of contact areas, identifying a priority of each of the plurality of contact areas based on a preset rule; and
determining the grip position as a contact area having a highest priority.
7 . The method of claim 1 , wherein the identifying the rotation of the first object comprises:
identifying a first time point at which the rotation of the first object starts;
determining an accumulated amount of movement from the first time point up to a current time point; and
determining the rotation based on the accumulated amount of movement.
8 . The method of claim 7 , wherein the first time point is an earliest time point from among consecutive time points at which an amount of movement during a period of time is equal to or greater than a preset threshold.
9 . The method of claim 1 , wherein the first object comprises at least one of a touch sensor or a rotation sensing sensor, and
wherein the identifying the rotation of the first object comprises:
obtaining sensing information from the first object via the at least one of the touch sensor or the rotation sensing sensor; and
determining the rotation based on the obtained sensing information.
10 . The method of claim 1 , further comprising displaying a user interface (UI) corresponding to the operation being performed.
11 . An augmented reality (AR) device comprising:
a camera configured to obtain an image;
a display;
a memory storing at least one program comprising at least one instruction; and
at least one processor configured to execute the at least one instruction to:
identify a first object from the image;
identify a grip position at which a user grips the first object;
identify a rotation of the first object; and
perform an operation based on the grip position and the rotation of the first object.
12 . The AR device of claim 11 , wherein the at least one processor is further configured to execute the at least one instruction to:
identify at least one feature point from the image;
identify a hand of the user based on the detected at least one feature point; and
identify the grip position based on a position of the hand of the user and a position of the first object.
13 . The AR device of claim 11 , wherein the at least one processor is further configured to execute the at least one instruction to:
in a case that the user contacts the first object at a plurality of contact areas, identify priority of each of the plurality of contact areas based on a preset rule; and
determine the grip position as a contact area having a highest priority.
