Four keying logics for the entry of alphanumeric characters were evaluated for keying speed and accuracy. The logics were selected based on their compatibility with current keyboard designs being used for the pilot-aircraft interface with communication, navigation, and other aircraft subsystems. A logic utilizing individual keys (36) for alphanumeric character keying was significantly faster than three other logics which used push-button matrix (telephone) keyboards. All logics were equally accurate, with an error rate of approximately .5 percent. Significant performance differences among the three matrix keyboard logics were inconsistent.
