Abstract: | The aviation industry is investigating reduced crew flight deck operations as a solution to an impending pilot shortage and to reduce costs. A shift in operation requires a shift in interaction. This new interaction should be flexible, natural, and minimize task interference when managing multiple concurrent tasks. Gaze, voice, and gesture interaction techniques can provide such interaction. As an extension to existing research, this dissertation investigates how these interaction techniques, independent of input device technology or task design, affect an operator's ability to manage concurrent tasks. To test this, an interaction framework was developed, consisting of a model of human information processing and a device-independent interaction taxonomy. Ten human factors experiments were conducted to validate the framework and answer the research question. The experiment tasks were abstracted from flight deck tasks. The effects of the six investigated interaction techniques on the costs of concurrent task management were measured via interruption and resumption time, performance of the first and second task, and subjective workload. Interaction technique was found to have a significant effect on resumption and interruption time, but not on performance or subjective workload. Multimodal interaction, while providing flexibility, results in less effective concurrent task management when compared with unimodal interaction. It was also found that neither gender nor previous pilot experience had an effect on the operator's ability to manage concurrent task demands. The results of this work were then applied to the construction of a mobile flight deck simulator to demonstrate the author's vision for reduced crew flight deck operations with multimodal interaction. The simulator depicts six realistic scenarios of a reduced crew flight with investigated interaction techniques. Practical demonstrations have shown that the interaction is flexible, robust, and natural. The device-independent, (multi)modal interaction framework will provide a baseline for effective concurrent task management workflows using gaze, voice, and gesture interaction techniques towards the implementation of reduced crew operations. |
