Description of the invention: [Technical field to which the invention pertains] ▲ The present invention relates to a wheeled device, and more particularly to an input device that does not count. [Prior Art] With the development of multimedia technology, computers have been able to accurately represent the colorful three-dimensional images in the real world. Users can access computer-aided design software such as 祀-Max, Sketch-up, and AutoCAD through mouse, keyboard, handwriting, tablet, and other input devices, such as 祀-Max, Sketch-up, and AutoCAD. However, in space design, whether through computer-aided design software or manual drawing, the designer can only express and present the design in scale. Design drawings in scales are not easily understood by the general public who have not received architectural design training, and often cause poor communication between designers and operators. Moreover, the design drawings presented by the designers are also easy to fall with the sighs that the industry thinks. Therefore, how to effectively grasp the spatial scale to carry out space design is very important. SUMMARY OF THE INVENTION The present invention provides a spatial design input device that allows a designer to effectively grasp the design of a spatial scale and draw objects into a three-dimensional image. The present invention provides a spatially designed input device that is suitable for a drawing system. The input device includes a light emitting module and a photography module. The light emitting module includes a first transceiver unit and a light source. The first transceiver unit is configured to communicate the light 5 1379217 0970054TW 28520twf.doc/n line transmitting module with the edge map system. The light source is connected to the first transceiver unit. When the light emitting module receives the first input command, the light source emits light to the real world. The photography module includes a second transceiver unit, an image capture unit, and a ray tracing unit. The second transceiver unit is configured to enable the camera module to communicate with the graphics system. The image capturing unit is coupled to the first transceiver unit. The unit captures the real world and outputs the background image to the drawing system, so that the drawing system produces a three-dimensional image corresponding to the background image. The ray tracing unit is lightly connected to the first acknowledgment: the ray tracing unit measures the movement path of the ray to the real world, and generates a control signal to the drawing system to cause the drawing system to draw the i object into the three-dimensional image. In the first embodiment, when the light-emitting module receives the input, the drawing system is based on the surface of the towel in the first dimension image. In the second embodiment of the wheel device, in the embodiment, the distance measuring unit, i, the brother-transceiver unit is further included. #光发赖接接(四)第:, 'The distance measuring unit changes according to the distance from the light emission to the real world, I = 2= to _ New, so that the drawing line extends in the three _ image ς single-upper wheel ^ In one embodiment, the device further includes an axial value detection 70 coupled to the first transceiver unit. When the light is emitted and the '/, ^ command is commanded, the axial rotation detecting unit generates a third control signal to the edge map system according to the light emission to the angle change, and the data is rotated to rotate the object. The input device is further included in the embodiment, and further includes an axial value detection 6 1379217 0970054TW 28520 twf.doc/n unit, which is coupled to the first transceiver unit. When the light emitting module receives the third input command, the third control signal is generated to the drawing system according to the change of the moving angle of the light emission to the real world, so that the drawing system rotates the object. The input device of the present invention uses the photographic module to capture the real world, so that the drawing system generates a three-dimensional image corresponding to the real environment, and draws the object into the three-dimensional image by detecting the moving path of the light in the real world. In this way, the user can grasp the spatial scale and carry out the space design in the real world.
