abstract="A multifunction switch is one way to solve the diminishing real estate problem in the modern cockpit. This study looked at pictorial coding of such a switch. Twelve different symbols were used, each with three levels of complexity and two levels of polarity. An error rate count was taken for subjects under both a naive and learned 50 millisecond exposure condition. This study demonstrated that there were three classes of symbols. These were: intuitive to the naive subject, intuitive to a learned subject, and non-intuitive, even to a learned subject. Complexity levels had a significant effect in only three of the twelve symbols. Polarity differences also had a significant effect in only three of the twelve symbols, although they were a different three. The overall conclusion is that the majority of symbols were intuitive after learning and robust to changes in complexity and polarity.<p /><p>Language: en</p>",
