The invention provides a general gesture command transmitting and operating device and method and belongs to the field of electronic appliance control. The device comprises a computer, a camera, a card master page, cards, a wireless transmitter and a wireless receiver. The cards are graphs, or images, or symbols or identification with a semantic or operation function. A virtual interface corresponding to the cards has certain functional distribution. The card master page is a physical plane and provided with one or more different cards for representing the images or the graphs of different control objects or control functions. The camera obtains image data on the card master page and transmits the image data to the computer. The computer segments all the cards and recognizes the cards.
