Abstract: A three-dimensional model providing system and a method thereof are provided to offer the three-dimensional model to a mobile terminal which does not have 3D engine for rendering the three-dimensional model. A storage unit(111) stores a plurality of three-dimensional models. A controller(112) forms a list of the multiple three-dimensional models in response to the connection of a mobile terminal, and generates rendering request information and image file formation request information based on the selection information of a specific three-dimensional model from the mobile terminal. A renderer(113) extracts a three-dimensional model corresponding to the selection information from the storage unit, and then forms rendering data by rendering the three-dimensional model.

Abstract: A 3D interaction system and method based on gaze and a 3D gaze tracking system and method are provided to determine a gaze direction by using the image of a user's eye and determine a gaze depth by using an interval between centers of pupils obtained from the images of user's both eyes, thereby quickly determining a 3D gaze. A 3D(Three-Dimensional) interaction system(100) based on gaze comprises a display unit(10), two light sources(12a,12b), an image acquisition unit, a first signal processing unit, a second signal processing unit, and a third signal processing unit. The display unit displays at least a 3D image. The light sources are aligned in both sides of the display unit. The image acquisition unit acquires both eye images of a user gazing the 3D image. The images of both eye include reflecting points formed by the light sources and the images of two pupils within both eyes. The first signal processing unit produces the reflecting points inputted from the image acquisition unit and a gaze direction and a gaze depth from the images of the pupils. The second signal processing unit determines the gaze of a point which the user gazes within the 3D image from the produced gaze direction and the gaze depth. The third signal processing unit executes the command of the user according to the determined gaze.
