Abstract

An information transmitting method and an electronic device using the method are described. The method includes establishing a communication connection with an electronic device; projecting a to-be-transmitted object information into a display screen of the electronic device; transmitting the to-be-transmitted object information to the electronic device to make the electronic device display the to-be-transmitted object information in the display screen. The first electronic device includes a connecting unit, a projecting unit and a transmitting unit. The second electronic device includes a connecting unit, a receiving unit and a display unit. As a result, transmission of the to-be-transmitted object information between devices based on projection achieves a seamless operational experience combining an actual condition and a virtual condition, and the projecting mode is simple and convenient and intuitive and highly effective, which improves features of real-time and ease of use of the transmitted object.
