Abstract
Projection methods and systems are disclosed in this disclosure. In an implementation, a method includes: A first device that displays first content, detects a first gesture operation, and recognizes the detected first gesture operation, where the first gesture operation is a continuous and moving gesture operation; a second device detects the first gesture operation, and recognizes the detected first gesture operation, where the second device establishes a communication connection to the first device; if recognizing that the first gesture operation is a projecting gesture, the first device projects, to the second device, the first content displayed by the first device; and if recognizing that the first gesture operation is a projected gesture, the second device receives the first content projected by the first device, and displays the first content on the second device.
