Systems and methods for sign language recognition are described to include circuitry to detect and track at least one hand and at least one finger of the at least one hand from at least two different locations in a room, generate a 3-dimensional (3D) interaction space based on the at least two different locations, acquire 3D data related to the at least one detected and tracked hand and the at least one detected and tracked finger, extract 3D features associated with the at least one detected and tracked hand and the at least one detected and tracked finger, analyze a relevance metric related to the extracted 3D features, classify at least one pattern from each of the at least two different locations based on a fusion of data outputs by the circuitry, and generate a recognized sign language letter based on the fusion of the data outputs.
