Gesture interfaces have long been pursued in the context of portable computing and immersive
environments. However, such interfaces have been difficult to build, in part due to a lack of
frameworks for their design and implementation. This paper presents a framework for automatically
producing a gesture interface based on a simple interface description. Rather than defining hand
poses in a low level high-dimensional joint angle space, we describe and recognize gestures in a
“lexical” space, in which each hand pose is decomposed into elements in a finger-pose alphabet.
The alphabet and underlying rules are defined as a gesture notating system called GeLex. By
implementing a generic hand pose recognition algorithm, and a mechanism to adapt it to a specific
application based on an interface description, developing a gesture interface becomes
