Abstract
Development of a four key typewriter for Hebrew characters is described. It capitalizes on the visual imagery capabilities of human operators. Parallel and sequential key strokes are employed as graphic elements to reproduce the shape of printed letters. Preliminary experiments show that letter-shape code is acquired with little training and is highly resistant to forgetting. Single hand blind typing at a relatively fast rate is achieved after few hours of training. No difference is revealed between right and left hand operation. Only small and non reliable decrements in data entry rates were observed when system was operated during a simulated flight mission in a F-4 simulator.Keywords
