A Comparison of Speech Input and Touch Screen for Executing Checklists in an Avionics Application

A range of input and control methods has been developed to ease the interaction between human and machine. This study considers two of these methods: speech recognition and touch screen. An experimental study was conducted that compares the use of speech and touch for executing checklists in a flight deck simulator. Findings showed that the use of speech recognition disrupted the primary tracking task to a lesser extent than control through a touch screen, and was preferred by participants. However, checklist completion was slower when speech was used. Limitations of this study and directions for future research are discussed.
