Abstract
A method and system are disclosed for encoding signs in a given sign language. The sign typically uses a dominant hand for some signs and a second hand is used for other signs the dominant hand remaining dominant of the two hands. In order to encode the signs into a useful form, each hand has various articles defined. The first article is that of handshape for both hands. The next article is that of palm orientation, with location and movement being the next two articles. A parametric value is associated with each of these particular articles. A combination of the articles, such as an article's concatenation in a parametric value string, allows for the transcription of a particular sign. Using this parametric value or even parts of the parametric value for the combined sign, a desired sign or a group of signs may be identified that closely resembles the particular sign being encoded. From this group of signs, the user can identify the exact sign that is of interest or that matches the sign desired by the user. A unique total parametric value is defined for each sign within the given sign language for matching against any of the articles identified by the user.
