Didactic device to improve penmanship and drawing skills

摘要

A didactic device for providing a learning experience and/or entertainment by serving as a learning aid to improve penmanship and drawing skills. The didactic device combines an optical image processing system with a speech synthesis system, wherein a drawing surface is provided in registration with the field of view of an optical imager. The user of the didactic device is requested either visually via a display mounted on the housing of the didactic device in proximity to the drawing surface or verbally via speech synthesis electronics to write or draw something on the drawing surface. When the user has completed the assignment by drawing indicia on the drawing surface, the image processing system, which includes an imager chip, a matrix memory in which signal data output from the imager chip is stored, and a data processor having an object recognition comparator, is actuated. The imager views the indicia as drawn by the user on the drawing surface and provides a signal data output indicative of the appearance of the indicia. The drawn indicia is then compared via the recognition comparator with the particular object configuration stored in memory and corresponding to the drawing instruction given to the user. Based upon the comparison, the speech synthesis system then gives an audible verbal response critiquing the writing or drawing of the user on the drawing surface and may be accompanied by visual showing of the correct drawing on the display.
