Abstract
A drawing apparatus which allows a user to select various writing sensations without experiencing an unnatural operational feeling. This drawing apparatus comprises operating device designed to be movable within predetermined space; detection device which detects a moving position of the operating device within the space; display device which displays an image according to a locus of the operating device based on a detection output of the detection device; and driving device which imparts a reaction force to the operating device in motion. As the operating device is moved along an imaginary surface in the space, the image according to the locus of the operating device is displayed, the detection device detects a moving speed and/or velocity or an output of a pressure sensor corresponding to each position of the operating device in the space, and the driving device imparts the reaction force according to a detection result from the detection device to the operating device.
