Abstract: In a field of electronic device technologies, a human-computer interaction method and device relates to a portable device receiving a first touch operation performed on a first image, where the first touch operation is directly performed on an area outside a first functional area, and the first functional area is a functional area in the first image. The portable device sends first data to a large-screen device, where the first data includes image data generated by the portable device in response to a second touch operation, the second touch operation is an operation that is generated based on the first touch operation and that is directly performed on the first functional area, and the first data is used by the large-screen device to update the second image.
