Abstract:
An electronic device is disclosed. The electronic device includes a communication interface such as a transceiver, a display, a processor electrically connected to the communication interface and the display, and a memory electrically connected to the processor, wherein the memory stores instructions for controlling, when executed, the processor to transmit a reception reject message to a caller device through the communication interface in response to an incoming call received from the caller device, to create a call back reminder linked to caller identification information of the caller device when the reception reject message contains context of a call back intention, and to output a notification of the created call back reminder.
Abstract:
An electronic device for displaying AR includes: an optical engine; a first polarizer; a polarization converter configured to maintain or convert a polarization direction of light of a real scene; a waveguide from which light of a virtual image is output and through which the light of the real scene is transmitted; a focus tunable lens; a second polarizer; and one or more processors. The one or more processors are configured to, during a first period, control the polarization converter to convert a polarization direction of a first light of the real scene such that at least part of the first light of the real scene is blocked by the second polarizer, and during a second period, control the polarization converter to maintain a polarization direction of a second light of the real scene such that the second light of the real scene is transmitted through the second polarizer.
