American Sign Language Linguistic Research Project

Investigation of the syntactic structure of ASL, with particular emphasis on the hierarchical representation of functional categories. Recent work has explored clausal structure: both the manual and non-manual expressions found with question phrases, tense, aspect, negation, and agreement.

Image and Video Computing Group

Research in the computer vision fields of person, head and skin tracking, and gesture recognition.

National Center for Sign Language and Gesture Resources

The goal of this project is to make available several different types of experimental resources and analyzed data to facilitate linguistic and computational research on signed languages and the gestural components of spoken languages. Collection of data from native users of ASL by means of synchronized digital video cameras, to capture multiple angles of the signing, is ongoing.
