Abstract
A user interface device which receives a user instruction for controlling at least one electronic device, includes a camera configured to obtain an image of a user; and at least one processor configured to divide the obtained image into a plurality of regions, determine an area occupied by the user's hand in each of the divided regions, and recognize gesture of the user based on the area occupied by the user's hand, wherein the at least one processor may be further configured to determine a direction in which the user's wrist faces based on the obtained image, and divide the obtained image into the plurality of regions based on the direction of the user's wrist.
Claims20
A user interface apparatus which receives a user instruction for controlling at least one electronic device, the user interface apparatus comprising:
- a camera configured to obtain an image of a user;
- and
- at least one processor configured to divide the obtained image into a plurality of regions, to determine an area occupied by the user's hand in each of the divided regions, and to recognize gesture of the user based on the area occupied by the user's hand,
- wherein the at least one processor is configured to determine a direction in which the user's wrist faces based on the obtained image, and to divide the obtained image into the plurality of regions based on the direction of the user's wrist,
- wherein the at least one processor is configured to set a second value for a ratio of the area occupied by the user's hand required to recognize a direction of the gesture in a second region among the plurality of regions to be smaller than a first value for a ratio of the area occupied by the user's hand required to recognize the direction of the gesture in a first region among the plurality of regions.
A vehicle comprising:
- a camera configured to obtain an image of a user;
- and
- at least one processor configured to divide the obtained image into a plurality of regions, to determine an area occupied by the user's hand in each of the divided regions, and to recognize gesture of the user based on the area occupied by the user's hand,
- wherein the at least one processor is further configured to determine a direction in which the user's wrist faces based on the obtained image, and to divide the obtained image into the plurality of regions based on the direction of the user's wrist, and
- wherein the at least one processor is configured to set a second value for a ratio of the area occupied by the user's hand required to recognize a direction of the gesture in a second region among the plurality of regions to be smaller than a first value for a ratio of the area occupied by the user's hand required to recognize the direction of the gesture in a first region among the plurality of regions.
A method of controlling a vehicle, the method comprising:
- obtaining an image of a user through a camera;
- determining, by at least one processor, a direction in which the user's wrist faces based on the obtained image;
- adaptively dividing, by the at least one processor, the obtained image into a plurality of regions based on the direction of the user's wrist;
- determining, by the at least one processor, an area occupied by the user's hand in each of the divided regions;
- and
- recognizing, by the at least one processor, gesture of the user based on the area occupied by the user's hand,
- wherein the dividing the obtained image into a plurality of regions comprises setting a second value for a ratio of the area occupied by the user's hand required to recognize a direction of the gesture in a second region among the plurality of regions to be smaller than a first value for a ratio of the area occupied by the user's hand required to recognize the direction of the gesture in a first region among the plurality of regions.
