Recognition of human body poses and gesture sequences with gesture description language

This paper presents our new proposition of human body poses and gesture description methodology for Natural User Interfaces. Our approach is based on forward chaining inferring schema performed on the set of rules that are defined with formal LALR grammar. The set of rules is called Gesture Description Language (GDL) script while automated reasoning module with heap-like memory is a GDL interpreter. We have also implemented and tested our initial GDL specification and we have obtained very promising early experiments results.
