Telemetric input and servo-powered animatronic output "Waldos" (see wikipedia, "remote manipulator") can be used to input and output sign language. 200-300 signs (American Sign Language, Spark Charts, 2004) would cover about 2/3 of conversations while 2000-3000 signs (American Sign Language Concise Dictionary, M. L. Sternberg, Collins, 1994) would cover about 95 % . Each sign would be stored as a brief script. Input to a telemetric input Waldo would be recognized by matching against the recorded script (case vector). Output would be accomplished by sending the recorded script to a servo-powered animatronic output Waldo.
I see this as an extension to the way in which protolanguage was used by Asa H. See chapter 1 of my book "Twelve Papers" (www.robert-w-jones.com, Book). Each of the 3000 or so signs can be recorded in a single pass from an input Waldo. Association of these signs with events that occur in the world (and "meaning") is then learned by associative learning in the usual way by Asa H.
