Electronic device for identifying a hand and method for controlling the same

An electronic device, comprising:

• memory storing one or more computer programs;
• a time-of-flight (ToF) sensor;
• and
• one or more processors communicatively coupled to the memory and the ToF sensor,
• wherein the one or more computer programs include computer-executable instructions that, when executed by the one or more processors individually or collectively, cause the electronic device to:
• obtain, via the ToF sensor, at least one image, wherein the at least one image includes a hand, and the TOF sensor emits infrared (IR) light and receives IR reflection of the IR light emitted from the ToF sensor,
• identify a plurality of key points associated with the hand in the at least one image,
• generate a reflectivity map of the hand based on the reflection of the IR light received by the ToF sensor,
• identify a plurality of regions of the hand in the at least one image using the reflectivity map and the plurality of key points, and
• based on the identified plurality of regions, identify the hand as either a left hand or a right hand.

One or more non-transitory computer-readable storage media storing one or more computer programs including computer-executable instructions that, when executed by one or more processors of an electronic device individually or collectively, cause the electronic device to perform operations, the operations comprising:

• obtaining, via a ToF sensor of the electronic device, at least one image, wherein the at least one image includes a hand, and the TOF sensor emits infrared (IR) light and receives IR reflection of the IR light emitted from the ToF sensor,
• identifying a plurality of key points associated with the hand in the at least one image,
• generating a reflectivity map of the hand based on the reflection of the IR light received by the ToF sensor,
• identifying a plurality of regions of the hand in the at least one image using the reflectivity map and the plurality of key points, and
• based on the identified plurality of regions, identifying the hand as either a left hand or a right hand.
