摘要:
A sign language translation system and method that not only recognizes words of a sign language but also supplements omitted words between the words of the sign language, to thereby generate a spoken language. The sign language translation system has an input unit for inputting at least the motion of hands, a language generating unit responsive to the inputted motion of hands for recognizing the words corresponding to the motion of hands and generating a spoken language using the relationship between the recognized words, and an output unit for outputting the generated spoken language. The sign language translation system and method can translate a sign language into an easy-to-understand spoken language.

A semiconductor device has a first interconnection pattern formed on a semiconductor substrate, and a second interconnection pattern located in and over a through hole formed at a composite insulating layer structure. The composite insulating layer structure is constituted by a first inorganic insulating film and an organic insulating film. At a peripheral region of the second interconnection pattern, the organic insulating film is partially eliminated to form an eliminated portion. The semiconductor device also has a second inorganic insulating film which is formed over the organic insulating film and is directly formed on the first inorganic insulating film, via the eliminated portion.
