The invention discloses interaction methods based on holographic images. One of the interaction methods is applied between a terminal and a holographic image device, and includes: sending an operationrequest to the holographic image device according to a received operation instruction after the terminal establishes a connection with the holographic image device, wherein the operation instructionincludes at least one item in a nurturance instruction, a message instant pushing instruction and a timing reminding instruction; and displaying the holographic images by the holographic image device,and responding to the operation request. The invention also discloses an interaction system based on the holographic images. The holographic image device of the interaction methods based on the holographic images, the client and the system provided by the invention utilize the holographic images to accordingly respond according to the operation instruction, and thus the interaction methods basedon the holographic images, the client and the system of the invention are capable of real-time interaction with the holographic images, high in flexibility, simple to operate, and low in costs.
