Abstract
Integrating alternative control technologies into complex systems presents many challenges. Direct Voice Input (DVI) is one such technology being considered for operations within the complex Canadan Forces tactical helicopter domain. Most DVI research focuses on improving recognition rates by incorporating noise cancellation, adaptive speech algorithms, vocal chord sensors, and lip reading (Jennings & Rucker, 1995). Studies have reported over 99% recognition (Swail & Kobierski, 1997), which is better than humans in some circumstances. In contras, DVI performance may be sub-optimal in operational environments due to syntax and grammar issues (Farrell, Ebbers, & Sarkar, 1998), multiple task interference (Cain et al., 2001), inappropriate feedback (Farrell, Perlin, & Ho, 2001), as well as improper crew coordination procedures. If these challenges are not addressed, the crew may turn the DVI system off. This study looks at the impact of DVI on helicoper crew coordination procedures.
