Abstract: An electronic device configured to project an image on a screen whose curvature is variable, may include: a projector; at least one processor; a communication interface configured to communicate with the screen; and memory storing images and instructions that, when executed by the at least one processor, cause the at least one processor to: obtain a curvature value of the screen based on context information related to the screen; transmit a control signal through the communication interface to the screen for bending the screen based on the curvature value; correct an image of the images stored in the memory based on the curvature value; and control the projector to project the corrected image on the screen.

Abstract: An electronic device for controlling devices includes: a communication module configured to communicate with the devices; a memory configured to store computer-executable instructions; and at least one processor. The at least one processor when executing the instructions by accessing the memory is configured to: determine a target device of which an envelope is to be registered among the devices, determine a first control area for the target device based on (i) first coordinates of a location of the electronic device in a preset coordinate system, (ii) a first direction from the first coordinates to the target device, and (iii) a field of view (FoV) for the target device, determine a second control area for the target device, and register an overlap area as the envelope for the target device, the overlap area being where the first control area and the second control area overlap.

Abstract: The disclosure relates to an electronic apparatus configured to, identifying that whether a correction of echo elimination on a sound signal which is received through a sound receiver is needed, output a test sound signal to an external speaker, identify a correction value of the echo elimination based on a characteristic difference between the test sound signal and a feedback sound signal received from the external speaker in response to the output test sound signal, and obtain a user voice signal by performing the echo elimination on a sound signal received through the sound receiver based on the correction value.
