To the visually oriented, words are a distraction. We see before we speak, and hear before we understand. An overlay of words helps us to see and understand anew, but it is that first vision which most excites us. Words will never replace what my eyes have seen. (Douglas Faulkner. Living Corals. 1979.p.258)
For Track Changes research we record gestures to explore how these can be combined with written words to convey intended meanings to a wider audience.
