Electronic device for obtaining user input through virtual keyboard and method of operating the same

A method of operating an electronic device, comprising:

• obtaining a second image by cropping a first image obtained through a camera of the electronic device;
• detecting at least one finger object in the second image, the at least one finger object corresponding to at least one finger;
• determining at least one key column corresponding to the at least one finger object among a plurality of key columns of a virtual keyboard by:
• matching the plurality of key columns of the virtual keyboard to a plurality of regions of the second image, and
• identifying at least one region corresponding to at least one position of the at least one finger object among the plurality of regions of the second image;
• determining at least one key row corresponding to the at least one finger object among a plurality of key rows of the virtual keyboard,
• identifying, based on the determined at least one key column and the determined at least one key row, at least one virtual key corresponding to the at least one finger object among a plurality of virtual keys of the virtual keyboard;
• and
• identifying an input of the identified at least one virtual key, based on detecting a typing movement of the at least one finger object.

A non-transitory computer-readable medium having recorded thereon computer executable instructions that, when executed by a processor of an electronic device, cause the electronic device to:

• obtain a second image by cropping a first image obtained through a camera of the electronic device,
• detect at least one finger object in the second image, the at least one finger object corresponding to at least one finger,
• determine at least one key column corresponding to the at least one finger object among a plurality of key columns of a virtual keyboard by:
• matching the plurality of key columns of the virtual keyboard to a plurality of regions of the second image, and
• identifying at least one region corresponding to at least one position of the at least one finger object among the plurality of regions of the second image,
• determine at least one key row corresponding to the at least one finger object among a plurality of key rows of the virtual keyboard,
• based on the determined at least one key column and the determined at least one key row, identify at least one virtual key corresponding to the at least one finger object among a plurality of virtual keys of the virtual keyboard, and
• identify an input of the identified at least one virtual key, based on detecting a typing movement of the at least one finger object.
