Synopsis

Gesture interfaces have long been pursued in the context of portable computing and immersive environments. However, such interfaces have been difficult to realize, in part due to the lack of frameworks for their design and implementation. Analogical to a game engine used to build computer games, a gesture interface engine is a framework which can be used to build gesture interfaces systematically, conveniently, and efficiently. Rather than using a low-level high-dimensional joint angle space, we describe and recognize handposes in a ¿lexical¿ space, in which each handpose is decomposed into elements in a finger state alphabet. A handpose is defined by finger spelling, i.e. by specifying the pose of each finger and the interrelation between any two fingers. Dynamic gestures are defined as handpose transformation, hand translation, and rotation. The alphabet and the underlying grammar, designed by the authors, form a simple but expressive gesture notation system called GeLex.
