Abstract: An interactive method using a floating image display and a system thereof are provided. The method is performed in the display apparatus. The display apparatus links to a computer system that executes a driver for establishing a communication interface there-between. In the method, the display apparatus receives image data from the computer system and floating image data can be obtained therefrom. The floating image display apparatus displays a floating image via a display panel after a conversion process. After that, a user can manipulate directly on the floating image by gesture. A procedure running in the display apparatus can determine an interactive instruction according to variations of three-dimensional coordinates. When the interactive instruction is transmitted to the computer system, a new image data is formed in response to the interactive instruction. The display apparatus then displays a new floating image after receiving new data.
